An Agreement To Protect Biodiversity | Earth Wise

January 18, 2023 By EarthWise Leave a Comment

The UN Biodiversity Conference in Montreal in December concluded with a historic deal aimed at stemming the rising tide of extinctions.  Nearly 200 countries signed on to the agreement to protect 30% of the Earth’s land and sea by the end of this decade.

Part of the agreement also pledges that countries will reduce fertilizer runoff from farms by 50%, reduce the use of harmful pesticides by 50%, and stem the flow of invasive species. 

Of course, all of these promises are only words unless they are backed up by actions and actions cost money.  The agreement promises to direct $200 billion a year towards biodiversity by the end of this decade.  Wealthy countries were urged to provide $100 billion a year to fund the actions of poorer countries, but they resisted the pressure.  Eventually, they did agree to send $30 billion a year to developing countries by 2030.

It is a significant step forward to establish clear targets for stopping biodiversity loss.  However, the ultimate success of the pact will depend on the willingness of countries to cooperate and compromise.

According to UN estimates, about a million species across the globe face extinction as a result of rising temperatures, air and water pollution, invasive species, and habitat loss due to development.   At present, only 16% of land and 8% of the oceans are within protected areas. 

The UN Environment Program stated that “for far too long humanity has paved over, fragmented, over-extracted, and destroyed the natural world on which we all depend.  Now is our chance to shore up and strengthen the web of life, so it can carry the full weight of generations to come.”

A Green New Year | Earth Wise

December 30, 2022 By EarthWise Leave a Comment

Every year, millions of people around the world make resolutions in hopes of sparking positive changes in the new year.  Popular resolutions include improving health and fitness, traveling more, spending less, and so on.  With the New Year just around the corner, here are seven resolutions we all could make that would collectively have a major impact on the planet: 

1) Eat less meat.  Resource-intensive animal-based foods like meat, dairy, and eggs are one of the chief contributors to climate change. 

2) Get a home energy audit.  It’s a great way to understand your home’s energy footprint and discover ways to improve the energy efficiency of your home. 

3) Buy local whenever possible.  Shopping locally supports the local economy and dramatically cuts down on the carbon emissions associated with shipping.

4) Carry reusable shopping bags on errands. While disposable shopping bags are convenient, they are difficult to recycle and are often thrown away. 

5) Air dry your laundry whenever possible.  Drying clothes outside or using an indoor drying rack can save money and energy.  Americans spend about $9 billion a year on electricity to dry clothing. 

6) Purchase used or pre-owned items.  The market for second-hand items is booming, making it possible to purchase pretty much anything you want at thrift stores or online. 

7) Bring a reusable water bottle everywhere.  According to the EPA, Americans throw away enough plastic bottles each year to circle the earth five times.  Carrying your own bottle helps reduce this waste and will save you money.

As we ring in the new year this weekend, let’s raise our glasses to a cleaner and greener 2023.

Climate Promises | Earth Wise

November 23, 2022 By EarthWise Leave a Comment

Countries are making climate promises, but are they following through?

The United Nations climate change conference that recently took place in Egypt is an annual event.  Last year, the conference was in Glasgow, Scotland, and the participants – heads of state and business leaders – produced a long list of promises aimed at fighting global warming.  How have the countries and companies making those promises done so far?  Unfortunately, not very well.

Participants made pledges for progress in several major areas.

Countries promised to cut greenhouse gas emissions faster, but only 24 countries out of the 140 participants have actually done so.

Countries agreed to expedite the deployment of clean energy and the phasing out of government subsidies for fossil fuels.  There has been considerable progress on green power, but coal use actually reached record highs this year primarily because of Russia’s invasion of Ukraine, which caused natural gas prices to spike.

Countries pledged $100 billion a year to help poorer countries shift to cleaner energy sources.  There has been lots of effort in this area, but the target has not been met and it isn’t clear that all the money is going where it is supposed to.

More than 100 countries pledged to slash methane emissions, but most nations are only getting started.

More than 130 countries pledged to halt and reverse deforestation by 2030.  Deforestation is slowly declining, but not fast enough to meet the goals of the pledge.

An important goal for this year’s climate conference was to try to find a way to not just set admirable and valuable climate goals, but to actually accomplish them.  It isn’t easy, but it is essential.

Planting Millions Of Trees Isn’t So Easy | Earth Wise

November 11, 2022 By EarthWise Leave a Comment

Mass tree plantings are not always effective

There are initiatives around the world to plant millions of trees as a way to fight climate change.  Unfortunately, scientists have observed that many of these projects are ill-conceived and poorly managed.  Some have failed to grow any forests at all.

One such project was an attempt to plant a million mangrove seedlings in coastal mud on the Filipino island of Luzon in 2012.  Ten years later, less than 2% of the trees have survived.  The other 98% have died or have washed away.  The problem was that the site of the project was ecologically unsuited to mangroves because it is too waterlogged and there is no oxygen available except in a few sheltered spots.

In 2019, the Turkish government managed the planting of 11 million trees in 2,000 sites across the country.  A later survey found that 90% had died, although the government denies that assertion.

Many other projects have also had dismal results.  The causes of failure vary but include planting single species of trees that become vulnerable to disease, competing demands for land, changing climate, planting in areas not previously forested, and lack of ongoing care for the saplings including watering them.

Nobody is opposed to mass tree planting.  There is no anti-tree lobby.  But tree planting is sometimes a form of greenwashing.  It is great for public relations but unless it is done properly with appropriate planning, it can be a waste of effort and money.  The result can be a phantom forest that does nothing for the climate.

Forest planting can work if the social and environmental conditions are right, and if planting is followed by long-term monitoring and care of the trees.

Decarbonizing Could Save Trillions | Earth Wise

October 18, 2022 By EarthWise Leave a Comment

Decarbonizing could save $12 trillion globally

Scientists have long been calling for a transition to clean energy to prevent catastrophic impacts of climate change.  For much of that time, many people and, specifically, many of those in power, were skeptical of the need to do something about the warming climate.  But even as the facts about the changing climate became increasingly undeniable, there continued to be fears that the transition to clean energy sources would be unacceptably expensive and harmful to the economy.

A recent study published by Oxford University shows that the opposite is true:  a concerted effort to convert to green energy technologies such as solar, wind, and batteries, will save the world enormous amounts of money.

The Oxford study shows that a transition to nearly 100% clean energy by 2050 results in a lower-cost energy system that provides energy access to more people around the world.  The energy transition is expected to save the world at least $12 trillion compared to continuing our current levels of fossil fuel use.

The cost of renewable energy sources has been going down for decades and they are already cheaper than fossil fuels in many situations.  It is expected that they will become cheaper than fossil fuels across almost all applications over time.  Accelerating the transition will allow renewables to become cheaper faster.

The study made use of probabilistic models to estimate the costs of various possible future energy systems based on past data.  Even the most pessimistic models showed that scaling up green technologies is likely to drive their costs down so far that they will generate net cost savings and that the faster the transition goes, the more will be saved.  The result will be a cleaner, cheaper, more energy secure future.

Saving Money By Predicting The Wind | Earth Wise

July 1, 2022 By EarthWise Leave a Comment

Managing an electrical grid that utilizes significant amounts of intermittent generation sources – solar and wind power – brings with it some unique challenges.  There are abundant wind resources in this country and more and utilities are taking advantage of these resources.   But there are times when there is more wind, times when there is less wind, and times when there is no wind at all.   Utilities need accurate wind forecasts to determine when they need to generate or purchase energy from alternative sources.

Poor wind forecasts can cost utilities a lot of money.  If there is overprediction – that is, when there is less wind than predicted – utilities have to purchase energy off the spot market at higher prices.  If there is underprediction – more wind than predicted – utilities may needlessly burn fossil fuels and waste money that way. 

The National Oceanic and Atmospheric Administration produces wind forecasts using its High-Resolution Rapid Refresh (HRRR) weather model, which provides hourly updated forecasts for every part of the United States looking forward up to 48 hours.  The model generates predictions of wind speed and direction at multiple levels of the atmosphere, information that utilities can use to predict the output of their wind turbines.

A new study by economists and scientists from Colorado State University and NOAA estimated the financial impact of the HRRR model on wind farm production.  The research team calculated that increasingly accurate weather forecasts over the last decade have saved consumers over $150 million a year.   Estimates are that if the newest model was in use in previous years, the savings would have been over $300 million a year.

New York Bight Offshore Wind | Earth Wise

May 2, 2022 By EarthWise Leave a Comment

Late in February, the U.S. completed the most successful offshore wind lease auction in history.  The auction for rights to develop offshore wind in the New York Bight brought in a record $4.37 billion from the companies bidding for them.

The New York Bight is an area of ocean off the coasts of New York and New Jersey that the Bureau of Ocean Energy Management has divided into six lease areas for offshore wind development.  It covers a total of 480,000 acres.  The more than $4 billion secured in the auction is more than three times the revenue received from all U.S. offshore oil and gas lease auctions over the past five years.

Five out of the six winning bids have European connections in the form of various partnerships.  Europe has a far more advanced offshore wind market than the U.S. with a total of 25 GW of installations as of 2020.  Winning bidders included participation by RWE from Germany, British-owned National Grid, and Copenhagen Infrastructure Partners, among others.  Chicago-based Invenergy was the only American company without a European partner to have a winning bid.

The expected installed capacity for the 6 leased areas in the New York Bight is expected to be between 5.6 and 7 GW, enough to power 2 million homes.  The Bureau of Ocean Energy Management said capacity could be even higher.

The successful action has set the tone and expectations for auctions to come.  BOEM has six more offshore wind auctions planned over the next three years.  Forthcoming auctions are for areas of the Carolinas, Northern and Central California, the Gulf of Mexico, the Central Atlantic, Oregon, and the Gulf of Maine.

Cleaning Up Abandoned Wells | Earth Wise      

March 3, 2022 By EarthWise Leave a Comment

Addressing the abandoned oil and gas wells

There are 130,000 documented abandoned oil and gas wells in the US, according to the Department of the Interior.  The key word is documented.  According to an EPA study in 2018, the actual number of abandoned wells could be as high as two or three million.  According to an analysis by the Environmental Defense Fund and McGill University, about nine million people in the United States live within a mile of one of these wells.

Some of these wells might be fairly harmless, and others might be quite dangerous.  Wells can emit a variety of gasses, including methane, which is a far stronger greenhouse gas than carbon dioxide.  Leaking wells are a major source of air and groundwater pollution.  Apart from methane, substances such as arsenic can continue to leak from wells even after they are no longer operational.

At the end of January, the Biden Administration announced a series of new actions to tackle methane pollution.  Among these measures is $1.15 billion in funds from the Department of the Interior that states can use to seal up abandoned oil and gas wells.  That funding comes from the Bipartisan Infrastructure Law passed in November, which sets aside $4.7 billion for a federal program dedicated to orphaned wells.

Addressing the largely ignored problem of abandoned wells is important from the standpoint of climate pollution as well as human health.  Efforts to plug the wells will also provide high-paying jobs

Other methane-reduction measures include increased enforcement from the Department of Transportation on reducing pipelines leaks, research funding for limiting methane emissions from beef and dairy farming, and technical assistance from the Department of Energy on well-plugging efforts.

Eating To Help The Planet | Earth Wise

November 30, 2021 By EarthWise Leave a Comment

Agriculture accounts for more carbon dioxide emissions than transportation.  Producing our food is one of the largest contributors to climate change.   Experts agree that the world cannot achieve net zero emission targets without changing our diets.  Be that as it may, we still have to eat. 

According to experts from Oxford University, there are things we as individuals can do to lower the impact of the food system on the climate.

There are three primary actions that would have the greatest impact: avoiding eating too much, cutting down on food waste, and reducing consumption of meat and dairy.

We all know that overeating is bad for our health, but it is also bad for the environment as it drives excess production and the emissions associated with it.

Food waste occurs across the supply chain but much of it is in the hands of consumers.  Food waste costs us a lot of money and is associated with emissions that are ultimately unnecessary.  The goal of the consumer should be to buy only the food one needs and to eat what one buys.

Meats, particularly from ruminant animals, result in the highest emissions per pound of food compared with vegetables, grains, and such.  Some people have given up animal proteins entirely, but properly managed livestock are an important part of the agricultural ecosystem and provide valuable services including enhancing the carbon sequestering ability of grasslands.  Nevertheless, it is important to reduce the global demand for meat and thereby prevent the need to clear more land for livestock and reduce emissions from meat animals.  So, we should all eat less meat and dairy even if we don’t become vegetarians.

Community Solar With Storage In New York | Earth Wise

November 16, 2020 By EarthWise Leave a Comment

Community solar

Community solar allows members of a community to share the benefits of solar power even if they cannot or prefer not to install solar panels on their own property.  There are several models for how community solar works, but all of them allow members to benefit from solar power being generated by an offsite solar array by effectively allocating a portion of its output to them.  In any event, community solar can save money on electric bills and allow people to make use of renewable energy for their needs.

A next step in the evolution of a decentralized energy system is incorporating energy storage into community solar projects.  The first one of these in New York State has now been completed in Yorktown Heights in Westchester County.  The project consists of 557kW of rooftop solar in the form of nearly 1,500 solar panels paired with 490kW of four-hour Tesla Powerpack battery energy storage.  The system is expected to provide 150 participants with approximately 10% savings on their monthly electric bills over 25 years, as well as providing power to 12 Tesla electric vehicle charging stations.

The project was funded by NYSERDA, under its Retail Energy Storage Incentive program, which currently includes 50 community solar-storage paired projects across New York State that are expected to be installed in the next two to three years.

New York has been actively promoting community projects in support of goals announced by Governor Andrew Cuomo to install 6,000MW of solar in the state by 2025 and 3,000MW of energy storage by 2030.

Paying To Combat Climate Change | Earth Wise

November 2, 2020 By EarthWise Leave a Comment

Fighting climate change

The majority of Americans believe that climate change is happening, that human activities are largely responsible, and are actually willing to put up their own money to help fight it.   Unfortunately, these views diverge sharply along party lines and, as in many other areas these days, the will of the overall majority has little influence on policy.

According to Yale University research, 73% of adults think that global warming in happening and 57% think it is mostly caused by human activities.  Furthermore, only 32% believe it is due to natural forces.

A survey conducted in the U.S. in August found that more than two-thirds of Americans – actually 70% – indicated willingness to donate a percentage of their personal income to support the fight against climate change.

Breaking that down further, 28% were willing to provide less than 1% of their income, 33% were willing to contribute 1-5% of their income, 6% said they would give 6-10% of their income, and 3% said they would contribute more than 10% of their income.  On the other hand, roughly 30% indicated that they were unwilling to contribute.

The survey also looked at opinions on how the fight against climate change should be paid for.  The majority (59%) chose government incentives for both businesses and consumers.   Three other options each favored by over 40% of those surveyed were taxes, conservation programs, and business investments. 

Another finding of the survey was that 44% are dissatisfied with the job that the federal and state governments are doing to address climate change, 35% are somewhat satisfied, and only 21% are very or completely satisfied with the government’s role.

An Incentive For Carbon Capture | Earth Wise

April 1, 2020 By EarthWise Leave a Comment

Convincing industries to reduce their carbon dioxide emissions has not been easy.  Many approaches have been debated, including carbon taxes, carbon tax-and-trade schemes, and passing a giant Green New Deal.  Most economists agree that putting a price on carbon is likely to be the most effective approach.

But there is already in place an adjustment to the US tax code that is more of a carrot than a stick.  It is a tax credit that is designed to make capturing CO2 a financial winner for a number of high-emitting industries.  The credit, called 45Q, was enacted in February 2018.

The 45Q credit earns industrial manufacturers $50 per metric ton of CO2 stored permanently or $35 per ton if the CO2 is put to use.  An earlier credit for capturing carbon dioxide was limited to only $20 per metric ton and was capped at 75 million tons.  Some large fossil fuel companies did make use of the earlier credit.

The new version does not have a cap, but to qualify, companies need to start constructing carbon-capture facilities within 7 years and have 12 years to claim their money.

Companies with emission-intensive operations are busy figuring out how to take advantage of the credit.  These include cement makers, steel and power plants, corn ethanol producers, and ammonia plants.

Because the credit mandates that companies start constructing their carbon-capture facilities within seven years, most companies will tend to rely on mature technologies.  But the tax credit should also drive demand for next-generation carbon-capture technologies, of which there are many under development.  Saving lots of money on taxes is likely to lure US companies to capture carbon dioxide.

Out-Migration And Reforestation

November 4, 2019 By EarthWise Leave a Comment

A challenging global trend is that of deforestation in developing countries.  But there are places where the opposite trend is happening.  Nepal is one such place.

According to satellite imaging, in 1992 forest covered 26% of Nepal.  As of 2016, that number was 45%. 

To some extent, the forest regrowth was a result of policy changes from about three decades ago, when the government began removing management authority from bureaucrats and shifting it to local communities across the country.  This local management helped to reduce illegal logging and many local villages undertook tree-planting campaigns.

But perhaps a bigger factor at play is human migration.  In recent decades, millions of Nepalis have left the country to work in the Persian Gulf, Southeast Asia, and elsewhere.  The out-migrants wire money home and meanwhile, families left behind rely less on forest products or abandon farmland, aiding reforestation.  A 2018 study showed that the areas with the highest out-migration experience, on average, had the most forest recovery.

Globally, migration has important impacts on forests, but not always positive ones.  In many countries, forests seem to recover as people leave rural areas to work elsewhere.  El Salvador, for example, has seen a rebound of its forests as many of its rural residents move to cities or even to the United States. But in Guatemala and Nicaragua, the return of migrants bringing money they have earned overseas has led to an expansion of cattle ranching that has harmed forests.

The global relationship between migration and forests is a complicated one that depends on whether the migration is one-way or “circular” (meaning that the migrants eventually return) and how returning migrants make use of their earnings from abroad.

Which Cities To Save From The Changing Climate

October 28, 2019 By EarthWise Leave a Comment

After several years of brutal flooding and hurricanes in the U.S., a distressing debate is emerging:  if there is not enough money available to protect every coastal community from the effects of global warming, how do we decide which ones to save first.

Recent research looked at the costs involved in providing basic storm-surge protection in the form of sea walls for all coastal cities with more than 25,000 residents.  That number was $42 billion.  Expanding the list to include communities smaller than 25,000 people would increase that cost to more than $400 billion.   Realistically, that is just not going to happen.

This particular study only looked at sea walls and no other methods for minimizing flood risk, such as moving homes and businesses away from the most flood-prone areas.   It also didn’t look at additional and costlier actions that will be required even with sea walls, such as revamping sewers, storm water, and drinking water infrastructure.

The facts are that many cities, especially small ones, will not be able to meet the costs facing them.  Those that can’t will depend on federal funding.  But even optimistically large proposals for federal infrastructure spending are likely to fall far short of the vast need.  Ultimately, the money will end up being spent where it can do the most good – even if it means that some places are left out.

But what criteria will be used to direct the money?  Economic value?  Historic significance?  Population?  Political influence?

This is a looming and massive issue whose chief obstacle may be that many officials refuse to acknowledge that it is happening.  This is the next wave of climate denial – denying the costs that we are all facing.

A Powerful Case For Protecting Whales

October 24, 2019 By EarthWise Leave a Comment

Efforts to mitigate climate change typically face two major challenges.  One is to find effective ways to reduce the amount of atmospheric carbon dioxide.  The other is how to raise enough money to implement climate mitigation strategies. 

Many proposed solutions to climate change, like carbon capture and storage, are complex, expensive, and in some cases, untested.  What if there was a low-tech solution that was effective and economical?

Well, it turns out there is one, and it comes from a surprisingly simple, “no-tech” strategy to capture CO2: increase global whale populations. 

According to a recent analysis by economists with the International Monetary Fund, whales help fight climate change by sequestering CO2 in the ocean. 

Whales sequester carbon in a few ways.  They hoard it in their fat and protein-rich bodies, stockpiling tons of carbon apiece.  When whales die, they turn into literal carbon sinks on the ocean floor.  While alive, whales dive to feed on tiny marine organisms like krill and plankton before surfacing to breathe and excrete. Those latter activities release an enormous plume of nutrients, including nitrogen, iron, and phosphorous, into the water.  These so-called “poo-namis” stimulate the growth of phytoplankton, microscopic marine algae that pull CO2 out of the air and return oxygen to the air via photosynthesis.  Phytoplankton are responsible for every other breath we take, contributing at least 50% of all oxygen to the atmosphere and capturing approximately 40% of all CO2 produced. 

With other economic benefits like ecotourism factored in, economists estimate that each whale is worth $2 million over its lifetime, making the entire global population possibly a one trillion dollar asset to humanity.

Wildlife And The Border Wall

February 14, 2019 By EarthWise Leave a Comment

The border between the United States and Mexico is nearly 2,000 miles long, stretching from San Ysidro, California to Brownsville, Texas.  Discontinuous barriers currently cover approximately 650 miles of our southern border. As the particulars of how to better secure the remaining 1,350 miles of border are worked out, one thing is abundantly clear: extending physical barriers would negatively impact wildlife and the environment.

The Trump Administration has called for a 1,000-mile wall, which would cut across land that includes important habitats for wildlife.  According to an article signed by nearly 3,000 scientists, this plan would “threaten some of the continent’s most biologically diverse regions” by inhibiting species movement and triggering flooding. The paper, which was published in the journal Bioscience, highlights how more than 1,500 native animal and plant species would be affected by the wall, including 62 that are listed as endangered or vulnerable.

An extended border wall would not only impede movement of many wildlife species but it would also put pressure on creatures already in peril, such as the Mexican gray wolf and the Sonoran pronghorn.  Other at risk animals include the ocelot, black bear, and desert bighorn sheep. 

According to researchers, extending the border wall could cause problems for low-flying birds and insects. Even plants, including the endangered wildflower Zapata bladderpod and the threatened whiskerbush cactus, are particularly at risk.

According to a 2011 study, bird-watching and other forms of ecotourism in the Lower Rio Grande Valley brought in more than $344 million in economic activity and approximately 4,400 jobs. 

Preserving our natural heritage must be part of this national security discussion.

Saved By The Trees

February 1, 2019 By EarthWise Leave a Comment

The island of Kokota, part of the Zanzibar Archipelago off the coast of Tanzania, is tiny – only one square kilometer and home to just 500 people.  For centuries, its residents subsisted by harvesting the islet’s natural resources, including its trees.

By the early 21st century, the deforestation had become unsustainable and the islanders faced a crisis.  Fisheries were depleted, and rivers ran dry.  The changing climate brought rising sea levels, more erratic rainfall, and coral bleaching in the surrounding waters.  The situation looked hopeless.

But in recent years, the island has come back from the brink of ruin.  Reforestation efforts began in 2008 on the larger island of Pemba and on Kokota itself, led by a Pemba local and a Canadian tree planter who formed the non-profit Community Forests International.  Since then, nearly 2 million trees have been planted on the two islands.  Enthusiastic volunteers on Kokota usually help plant trees during the rainy season, when water is plentiful.

Community Forests International, along with spearheading the tree planting effort, also built Kokota’s first school, and installed rainwater storage tanks for the community.

The conservation group is now devising ways for Kokota to make more money by diversifying its agriculture with crops that grow well in its climate including spices like cloves, cinnamon, and nutmeg.  They are also helping locals to grow more and different vegetables in their gardens.

Small, poor communities are often the most vulnerable to the effects of climate change, such as drought, powerful storms, and depleted fisheries.  Tiny Kokota provides an example of an environmental comeback.  Fighting climate change requires economic solutions along with environmental solutions.  For this one tiny island, it  appears to have been saved by the trees.
