Renegade geoengineering

By Leave a Comment

As the dangers of climate change continue to grow, so has interest in geoengineering – deliberate tinkering with the earth’s climate system.  In particular, stratospheric solar geoengineering – releasing aerosols into the stratosphere to reduce the amount of heat from the sun reaching the Earth – is attracting increasing interest.  Scientists at Harvard, Cornell, Colorado State, Princeton, and the University of Chicago are all researching the topic.

Actually doing it on a scale that matters is fraught with peril from unintended consequences of disrupting the delicate interactions between the Earth’s atmosphere, ocean, land, and sea ice. 

Meanwhile, a tiny start-up company in Silicon Valley has raised more than a million dollars in venture capital and is busy releasing balloons full of sulfur dioxide into the atmosphere in the name of combatting global warming.  Furthermore, they are selling so-called “cooling credits” to customers who want to offset their personal carbon emissions.

The aerosol being released is on such a small scale that it can’t possibly have a meaningful effect on temperatures.  There really isn’t scientific analysis guiding or accompanying the work. 

There are no laws prohibiting the dispersal of small amounts of sulfur dioxide in California.  Even if there were, these people could go offshore or elsewhere to do their work.  But this renegade geoengineering highlights a serious issue; namely, that there doesn’t have to be scientific, political, or any other kind of consensus for someone to undertake a potentially catastrophic attempt to alter the climate.  It’s a real worry.

The right to not buy fossil fuels

By Leave a Comment

Minnesota has been one of the most aggressive states in setting and realizing clean energy goals.  As of this year, Minnesota gets 55% of its energy from net zero carbon emission sources.  The state has goals of reaching 80% green energy by 2030, 90% by 2035, and 100% by 2040.  Recent legislation in Minnesota aims at further reducing carbon emissions and job creation in the clean energy sector.

All of this is very good news, but not for the neighboring state of North Dakota.  Minnesota getting all of its energy from clean energy sources means that it would no longer be a customer for the fossil fuel products of North Dakota.

North Dakota is known for its vast reserves of coal, oil, and natural gas and, apart from agriculture, the energy industry is the biggest moneymaker in the state.  Faced with the aggressive clean energy initiatives of its next-door neighbor, North Dakota has threatened to sue Minnesota. 

What would be the basis of such a lawsuit?  The argument would be that Minnesota’s clean energy goals would be in violation of interstate commerce laws and infringe upon North Dakota’s economic sovereignty.  The claim would be that the energy regulations in Minnesota unfairly discriminate against North Dakota’s energy products.

Minnesota, on the other hand, would defend its energy goals as a legitimate exercise of its own state sovereignty and a necessary response to the climate crisis.

The outcome of any legal battle that may take place will have far-reaching implications for Minnesota and North Dakota as well as for other states across the country that have clean energy initiatives.

Koalas Are Endangered | Earth Wise             

By Leave a Comment

The koala is one of the world’s most iconic animal species and is widely considered to be the symbol of Australia.   Koalas are not bears; they are marsupials. 

Being iconic symbols is not sufficient to prevent koalas from going extinct.  In the 1920s, hundreds of thousands of koalas were shot for the fur trade, greatly reducing their population.

More recently, drought, bush fires, disease, and habitat loss have drastically reduced the numbers of koalas.  Since 2018, there has been a 30% decline in koala populations across Australia.  It is difficult to get an accurate count of the animals because they don’t move around much, and they live high up in tree canopies where they are hard to spot.

 Estimates are that the koala population has dropped from between 45,000-82,000 in 2018 to between 32,000-58,000 in 2021.  The koala is now extinct in 47 Australian electorates and in many others, there are only handfuls of animals remaining.   The population decline was accelerated by devastating wildfires in late 2019 into early 2020.  Some estimates are that koalas could be extinct by 2050.  Conservation organizations around the world have been demanding greater protection for koalas for years.

Given this dire situation, the Australian government recently declared the koala an endangered species, reclassifying it from being a vulnerable species.  The government plans to adopt a recovery plan that will include new laws protecting koalas and their natural woodland environments.  The details of the plan remain to revealed.

According to the Australian Koala Foundation, however, the new status of the koala means very little in and of itself.  If the clearing of the koala habitat continues, the species has little chance of surviving in the wild.

Five States Stepping Up On Clean Energy | Earth Wise

By Leave a Comment

While Congress continues to face partisan gridlock on climate issues, many states have moved forward with climate action.

In 2021, five states – Illinois, Massachusetts, Oregon, North Carolina, and Rhode Island – passed laws requiring a shift to 100% carbon-free electricity or net-zero emissions.  Washington State passed a law that helps to implement its strong 2019 and 2020 climate and clean energy laws.  Washington’s new legislation establishes a carbon trading program that will help the state to meet its goals of economy-wide emission cuts and 100% carbon-free electricity.

Several other states made progress on climate and clean energy by taking targeted actions not quite as aggressive as 100% laws, but significant, nonetheless.

The five states that entered the so-called 100% club joined with the six states that had earlier passed such legislation.  Those are California, Hawaii, New Mexico, New York, Virginia, and Washington.  Both Puerto Rico and Washington D.C. are also members of the club.

The past year may well be the biggest year yet for significant clean energy legislation.  Some of the states that finally passed laws had been gearing up for it for years.  This is particularly true of Massachusetts and Illinois.

Actions by individual states are not an antidote to inaction by the federal government, but they help.  At this point, about one-third of the country’s population lives in states that have laws requiring a transition to 100% carbon-free electricity, 100% renewable electricity, or net-zero emissions. 

All of this activity began in 2015, when Hawaii passed its renewable energy law.

Banning Gas Cars | Earth Wise

By Leave a Comment

The transition to electric vehicles from gas-powered vehicles is essential for reducing greenhouse gas emissions as well as air pollution in general.  Currently, transportation is responsible for 30% of greenhouse gas emissions in the United States.

There is no doubt that there is surging interest in electric cars.  There are now millions of them being sold around the world each year.  But they still represent a small fraction of new car sales in most places.  Notable exceptions are several European countries such as Norway and Switzerland where plug-in vehicles are dominant.  In the United States, on the other hand, EVs still represent less than 3% of new car sales.

Given the urgency in reducing vehicle emissions, many countries around the world have devised plans, goals, or laws to end the sale of gasoline cars.  Gas car bans vary quite a bit around the world, but they are being implemented in many places.

There are 28 countries and US states that have imposed gas car bans to take effect over the next five to 20 years.  These include European countries like Norway, Belgium, Austria, Netherlands, Denmark, Iceland, Ireland, Sweden, Scotland, Slovenia, the UK, France, and Spain.  Asian countries include South Korea, India, Japan, China, Singapore, Sri Lanka, and Taiwan.  In the Middle East, Israel and Egypt have announced bans.  Here in the US, New York and California both have bans starting in 2035.  Canada also has announced a ban.

Car manufacturers have seen the writing on the wall.  Most have started adding EVs to their lineups.  Many have announced their own timetables for phasing out gas cars entirely.  There are more than 15 new electric models available this year and there are many more to follow next year.

Progress Towards Carbon-Free Power | Earth Wise

By Leave a Comment

Climate change has driven countries, states, utilities, and corporations to set goals to eliminate power-sector carbon emissions.  So far, 17 U.S. states plus Washington, D.C. and Puerto Rico have adopted laws or executive orders to achieve 100% carbon-free electricity over the next couple of decades.  Forty-six U.S. utilities have pledged to go carbon-free no later than 2050.   Adding these together, these government and industry goals cover about half of the U.S. population and economy.

New research from the Lawrence Berkeley National Laboratory has analyzed historical trends to determine how much progress the power sector has already made in reducing emissions.  The study focused on the 2005 Annual Energy Outlook from the U.S. government’s Energy Information Administration.

If the previous growth in emissions had continued from 2005 to 2020, annual CO2 emissions would have risen from 2,400 to 3,000 million metric tons.  But actual 2020 emissions fell to only 1,450 metric tons.  So, by this metric, the U.S. power sector cut emission by 52% below projected levels.

According to the study, total consumer electricity costs were 18% lower than projected values, but meanwhile, the number of jobs in electricity generation was 29% higher. 

Among the driving forces for these trends were wind and solar power dramatically outperforming earlier expectations, delivering 13 times more generation in 2020 than projected. 

The study shows that dramatic changes in emissions are possible over a 15-year span, but much has to happen over the next 15 years to ensure the progress required to meet the ambitious goals set for emissions reductions.

Europe’s Green Deal: Bad For The Planet? | Earth Wise

By Leave a Comment

In 2019, the European Union announced the “Green Deal,” a comprehensive program aimed at making Europe the first climate-neutral continent, implementing environmentally friendly transport, increasing recycling, and expanding renewable energy.

The Green Deal involves significant changes to European agriculture.  Over the next ten years, under the ambitious environmental program, at least a quarter of all agricultural areas will be farmed organically, the use of fertilizers and pesticides greatly reduced, 3 billion trees planted, 15,000 miles of rivers restored, and the population declines of pollinators reversed.

However, in a recent article published in Nature, scientists at the Karlsruhe Institute of Technology show that this Green Deal might actually be a bad deal for the planet.

The problem is that the EU is likely to basically be outsourcing environmental damage by its high imports of agricultural products.

According to the Karlsruhe study, the EU annually imports millions of tons of agricultural products, as much as 20% of its produce and much of its meat and dairy products.  Quite often, these imports come from countries whose environmental laws are far less stringent than those in Europe.

The EU cannot impose environmental standards on other countries, but it can demand that goods entering the European market meet EU requirements.  The study points out that Europe’s carbon footprint has to be evaluated on a global basis.  If the EU is truly to become a climate-neutral continent, it must include foreign trade goals and requirements in its environmental programs.  Otherwise, Europe will simply be outsourcing its environmental problems and will continue to cause damage to the planet.

Environmental Injustice And the Coronavirus | Earth Wise

By Leave a Comment

Cities and towns across the United States continue to wrestle with the devastating impacts of the COVID-19 pandemic and none have been hit harder than low-income and minority communities.  Places like Detroit, Chicago, and St. James Parish in Louisiana have suffered from decades of economic inequality and pollution in their poorest neighborhoods and many of these same places have experienced some of the highest mortality rates from the virus.

Recent studies have shown a link between high levels of pollution and the risk of death from COVID-19.  Pollution of various kinds are higher in low-income communities and communities of color.  Such communities don’t have a strong political voice so that laws and environmental regulations are not enforced like there are in white, higher-income communities.  Thus, these communities have highways, landfills, factories, chemical facilities, paper mills, and other pollution sources that communities with economic power – and therefore political power – manage to avoid.

People living in low-income communities and communities of color tend to have higher rates of underlying health conditions like diabetes, heart disease, and asthma.  They have less healthy diets – more fast food and fewer grocery stores.  Part of the reason these communities have a higher risk of mortality from COVID-19 infection is that many people have reduced lung capacity as a result of exposure to pollutants.

The Trump administration has been suspending enforcement of environmental regulations during the pandemic.  Communities already affected by environmental injustice will bear the brunt of this decision.  Groups like nursing home populations, meat packers, prisoners and the poor are suddenly highly visible.  COVID-19 is exposing the real differences between the Haves and the Have-Nots in this country.

A Victory For Clean Water | Earth Wise

By Leave a Comment

Many of the nation’s environmental laws are under siege from the current administration, but a recent decision by the U.S. Supreme Court has solidified the Clean Water Act’s place as one of the country’s most effective environmental laws.

The case in question was about whether a wastewater treatment plant in Maui has been violating the Clean Water Act by polluting the ocean indirectly through groundwater.  Since the 1980s, the Lahaina wastewater treatment facility has been discharging millions of gallons of treated sewage each day into groundwater that reaches the waters off of Kahekili Beach, which is a popular snorkeling spot.   Groundwater, like any water beneath the land’s surface, can flow into major waterways such as rivers, streams, and, in this case, the ocean. 

In 2012, the nonprofit Earthjustice sued Maui county on behalf of four Maui community groups. Over the years, the Hawaii district court and the 9th Circuit appeals court ruled in favor of Earthjustice.  Last year, Maui County successfully petitioned the U.S. Supreme court to hear the case, which could have endangered the Clean Water Act.

On April 23, by a 6-3 vote, the court ruled that point source discharges to navigable waters through groundwater are regulated by the Clean Water Act when the addition of pollutants through groundwater is the functional equivalent of a direct discharge into navigable waters.

With this ruling, the Court rejected the Trump administration’s polluter-friendly position in the clearest of terms.  According to the opinion, written by Justice Breyer, the Court could not see how Congress could have intended to create such a large and obvious loophole in one of the key innovations of the Clean Water Act.  This is a victory for clean water.

Packing With Banana Leaves

By Leave a Comment

More and more places are instituting bans on single-use plastic bags.  Places like California and Hawaii already have bans in place and New Jersey is considering such a ban.  New York’s law will go into effect next March.  Supermarkets will no longer provide plastic bags at the checkout line.  But the laws have some exceptions, including the plastic bags used to hold produce and to pack up meats.

Banning or reducing single-use plastic bags is a growing trend in Asia as well including places like South Korea, Vietnam and Thailand.

One supermarket in Thailand came up with a novel approach to eco-friendly packaging:  wrapping produce in banana leaves.  The idea quickly became a viral hit on social media and drew the attention of supermarkets in Vietnam.  Several big supermarket chains in that country also began experimenting with banana leaves as a packaging alternative.

Representatives of Vietnam’s Lotte Mart chain said that the banana leaf packaging was still in the testing phase, but they plan to replace plastic with leaves nationwide very soon.  Aside from wrapping vegetables and fruits, the grocery chain intends to also use the leaves for fresh meat products.

Customers seem to be quite positive about the new packaging noting that it is actually quite attractive visually.  The banana leaf packaging also makes people more aware of the need for protecting the environment.

While Vietnam is a relatively small country, it turns out that it ranks number four in the world for the largest amount of plastic waste dumped into the ocean.  The country disposes of about 2,500 tons of plastic waste per day. So, efforts like the banana leaf packaging are not just symbolically important, they are genuinely a major environmental imperative.

Diesel Is Dirty

By Leave a Comment

Three years ago, Volkswagen was found to have illegally cheated federal emissions tests in the US using devious programming of emission control devices.  The subterfuge enabled 11 million passenger cars to meet U.S. emissions standards in the laboratory despite that fact that they actually produced up to 40 times higher emissions than the legal limit in real-world driving.
