The All-Time Hottest Day | Earth Wise

February 14, 2022 By EarthWise Leave a Comment

Last year saw record high temperatures in many places around the world and this year started out with more of the same. In mid-January, Onslow, a small town in Western Australia, measured a high temperature of 123.3 degrees, tying the all-time highest temperature ever recorded anywhere in the Southern Hemisphere. The previous reading was also made in Australia back in 1960.

The new temperature record was set just as climate institutions around the world were announcing that the past seven years have been the highest in recorded history.

The list of temperature records set in 2020 and 2021 is a long one. 2020 was the hottest year in recorded history. July 2021 was the hottest month ever recorded. The hottest official temperature ever recorded anywhere in the world was 129.9 degrees, occurring in Death Valley, California on both August 16, 2020, and July 9, 2021.

The hottest temperature ever recorded in the Arctic was 100.4 degrees on June 20, 2020 in Verkhoyansk in Russia’s Sakha Republic. (Amazingly, that small town also holds the record for the coldest temperature ever recorded in Asia at -90 degrees). 2021 saw an all-time high temperature recorded in Europe, in Syracuse, Sicily, on August 11 at 119.8 degrees.

Overall, 400 documented weather stations in communities or outposts worldwide established all-time high temperatures in 2021 alone. The climate we have lived through over the past decades is changing and these changes will have consequences to our way of life.

Solar Power In Australia | Earth Wise

October 13, 2021 By EarthWise Leave a Comment

Historically, the electricity sector in Australia has been dominated by coal-fired power stations. Even now, coal accounts for about 60% of Australia’s electricity generation. But since 2005, wind power and rooftop solar have led to a fast-growing share of renewable energy in total electricity generation.

Australia is the second-largest exporter of coal in the world and has proven reserves equivalent to over 1,200 times its annual consumption. Australia is home to four of the world’s ten biggest coal mines. But despite this abundant resource, the country is increasing its use of renewable energy.

For just a few minutes on a sunny Sunday afternoon in August, more than half of Australia’s electricity came from solar power. Low demand and sunny skies resulted in the contribution from coal dropping to a record low of 9,315 MW while solar power provided 9,427 MW.

In 2020, 24% of Australia’s electricity came from renewable energy, up from 21% the year before. The increase was driven by a boom in solar installation.

Australia is still a long way from meeting its commitments under the Paris Climate Change agreement. The country ultimately needs 51 GW of new renewable energy generation by 2042 but only 3 GW of new wind and solar projects have been committed to date.

Overall, Australia has promised what has been described as the fastest energy transition in the world. It is all very ambitious, but Australia has a lot of work to do.

Wind Power Update | Earth Wise

October 8, 2021 By EarthWise Leave a Comment

The Department of Energy recently released three reports showing record growth in land-based wind energy, a growing number of offshore wind projects, and the continuing reduction in the cost of wind power.

The U.S. installed a record amount of land-based wind energy in 2020. In total, 16,836 MW of new utility-scale land-based wind power capacity was added during the year, representing $24.6 billion in new wind power projects. This was more added than from any other energy source and represented 42% of new U.S. energy capacity.

For the year, wind energy provided more than 10% of in-state electricity generation in 16 states. Notably, wind provided 57% of Iowa’s electricity and more than 30% in Kansas, Oklahoma, South Dakota, and North Dakota.

As wind turbines continue to grow in size and power, they are producing more energy at lower cost. Turbine prices have gone from $1,800/kW in 2008 to $770-850/kW now.

The pipeline for U.S. offshore wind energy projects has grown to 35,324 MW, a 24% increase over the previous year. The Bureau of Ocean Management created five new wind energy areas in the New York Bight with a total of 9,800 MW of capacity.

Distributed wind power, which are systems connected on the customer’s side of the power meter as opposed to those on the utility side, also saw increased growth last year.

Wind power is a key element in the adminstration’s goal of having a decarbonized electricity sector by 2035.

Wildfires And The Climate | Earth Wise

September 24, 2021 By EarthWise Leave a Comment

Scientists from the National Center for Atmospheric Research recently published a study analyzing the events that influenced the world’s climate in 2020. Among these were the pandemic-related lockdowns that reduced emissions and resulted in clearer air in many of the world’s cities.

While this was a significant event, the study found that something entirely different had a more immediate effect on global climate: the enormous bushfires that burned in Australia from late 2019 to 2020, producing plumes of smoke that reached the stratosphere and circled much of the southern hemisphere.

Those fires sprung up in September 2019 and lasted until March 2020. The fires burned more than 46 million acres (about 72,000 square miles), which is roughly the same area as the entire country of Syria. Thousands of homes and other buildings were lost.

Major fires inject so many sulfates and other particles into the atmosphere that they can disrupt the climate system, push tropical thunderstorms northward from the equator, and potentially influence the periodic warming and cooling of tropical Pacific Ocean waters known as El Nino and La Nina.

According to the study, the COVID-19 lockdowns actually had a slight warming influence on global climate, as a result of clearer skies enabling more heat to reach the earth’s surface. In contrast, the Australian bushfires cooled the Southern Hemisphere because the atmospheric particles reflected some of the incoming solar radiation back to space.

This summer, there have been raging wildfires in the western US and Canada, which have affected air quality in many parts of the nation and have been a serious health hazard. Undoubtedly, these fires are influencing the climate system as well in ways that we are still trying to understand.

Wine And Wildfire Smoke | Earth Wise

September 22, 2021 By EarthWise Leave a Comment

Rising global temperatures have made droughts and heatwaves more common and intense, leading to larger and more destructive wildfires. In 2020, wildfires in California blackened more than 4 million acres, the largest wildfire season on record. With its continuing drought, California has already had 1.5 million acres burned by wildfires this year, and the fires continue.

Wildfires can cause extensive damage throughout the agricultural industry by destroying crops and killing livestock. But the fires can have a unique effect on the wine industry: wine grapes can be affected by smoke taint.

Vineyards have demonstrated themselves to be good fire breaks. They definitely help prevent the movement of wildfires. But there is no way to stop smoke from the fires from drifting into vineyards. By far, the damage caused by smoke far outweighs direct losses from fires in vineyards.

Winemakers sometimes add subtle smoky notes to their vintages by aging them in toasted oak barrels. But wildfire smoke permeating vineyards – even from distant blazes – can end up making wines undrinkable. Smoke-tainted wines end up having unpleasant aromas that people describe as being like disinfectants or burnt rubber.

With wildfires an increasingly persistent presence in California, the state’s $43 billion wine industry is facing a major challenge. An estimated 165,000 to 325,000 tons of California wine grapes went unharvested last year, adding up to more than $600 million in losses from fire and smoke. The industry will need to figure out ways to detect and manage smoke taint as the problem isn’t going to go away.

Promoting Biodiversity In Agriculture | Earth Wise

September 13, 2021 By EarthWise Leave a Comment

The organic foods industry is one of the fastest growing agricultural segments in the United States. According to the Organic Trade Association, U.S. organic sales reached $61.9 billion in 2020, a jump of more than 12% over the previous year.

Organic food has many benefits. Organic food is free of antibiotics, growth hormones, and GMOs, and is grown using fewer pesticides. Organic farming tends to be better for the environment by reducing pollution, conserving water, reducing soil erosion, increasing soil fertility, and using less energy. And it’s also better for the health of nearby wildlife as well as the people who live close to farms.

But when it comes to promoting biodiversity in agriculture, is organic farming the only alternative to conventional agriculture? It turns out it’s not – at least according to a new study recently published in the journal Trends in Ecology and Evolution.

According to an international research team led by the University of Göttingen in Germany, a landscape mosaic of natural habitats and small-scale and diverse cultivated areas is the key to promoting biodiversity on a large scale in both conventional and organic agriculture.

According to the research team, areas cultivated to organic standards have one third more species, but don’t reach the yield level of conventional farming. This means that more land would need to be cultivated organically in order to produce the same amount of food. But as larger areas are cultivated, the advantages for biodiversity would disappear.

Landscapes with small fields, long edges, high crop diversity, and at least 20% near-natural habitats can promote biodiversity significantly more than just organic certification.

Insanely Cheap Energy | Earth Wise

June 11, 2021 By EarthWise Leave a Comment

The International Energy Agency, founded in 1974, keeps track of the world’s energy systems and anticipates how they are likely to change over time. Policymakers around the world look to the agency’s annual World Energy Outlook publication for guidance.

In 2000, the agency made the prediction that by the year 2020, there would be a total of 18 gigawatts of photovoltaic solar power installed. Within seven years, that number was already too small.

The IEA was not the only source to miss the mark on solar power. The head of solar analysis at BloombergNEF in 2005 expected solar to eventually supply 1% of the world’s electricity. It is already 3% and Bloomberg now predicts that it will be 23% by 2050 and expects that to be an underestimate.

What has happened is that the world has unexpectedly gotten to the point where solar is the cheapest source of energy in most places. Over the past decade, every time solar production capacity has doubled, its cost has dropped by 28%.

Historically, a combination of groundbreaking research in Australia and intense Chinese industrial development led to the creation of a massive new industry. When Germany passed laws encouraging the use of solar power, suddenly there was massive global demand and a struggle to keep up with supply.

The industry had its fits and starts, and many players fell by the wayside. But at this point, solar technology continues to get better and cheaper. Market forces are pretty hard to beat and when solar technology can supply insanely cheap energy, it is going to be used in more and more places.

New Records For U.S. Wind Power | Earth Wise

March 22, 2021 By EarthWise Leave a Comment

Wind-powered electricity has been increasing its contribution to the American energy mix for years as the number of installed turbines has rapidly grown. In the final months of 2020, wind power set a number of new records. Strong wind conditions in November and December, especially in the central states, led to record output from wind turbines.

On April 10, 2019, the U.S. set a record for daily electricity generation from wind turbines in the lower 48 states by producing 1.42 million megawatthours. That record stood until several different days during November and December. The newest record was set on December 23 when wind generation reached 1.76 million MWh. That constituted 17% of total electricity generation in the U.S. For the entire year of 2020, wind power accounted for 9% of U.S. electricity generation.

Late 2020 also saw new records set for hourly dispatch of wind resources. On December 22, between 9 and 10 pm Eastern Time, 82 gigawatts of electricity sourced from wind power was dispatched across the U.S., breaking the one-month-old previous record of 73.4 GW. Wind power varies considerably over the course of a day. During December, wind power across the country varied between that record of 82 GW to a low of 14.6 GW.

The contributions from wind power are expected to continue to grow. The U.S. currently has over 112 GW of installed wind capacity. Project developers and grid operators plan to add another 12.2 GW of new wind capacity to the U.S. grid by the end of 2021. More than half of that new capacity will be in Texas and Oklahoma.

The Pandemic And Global Temperatures | Earth Wise

March 12, 2021 By EarthWise Leave a Comment

The early months of the Covid-19 pandemic last year saw dramatic reductions in travel and many forms of commerce. With much of human activity greatly curtailed, greenhouse gas emissions were greatly reduced. And yet, all of that did not slow down global warming: 2020 ended up tied with 2016 as the warmest year on record and atmospheric greenhouse gas levels reached a new high.

In order to understand how this came about, it is necessary to understand the complex climate influences of different types of emissions from power plants, motor vehicles, industrial facilities, and other sources. The fact is that some types of pollution actually have a cooling effect rather than contributing to global warming.

Tiny industrial pollution particles called aerosols actually make clouds brighter, causing them to reflect away more solar heat from the surface of the planet. During the drastic shutdown last year, the biggest emissions decline was from the most polluting industries. The reduction of aerosols had immediate, short-term effects on temperatures. These types of pollutants are very bad for human health, but when they are present, they do have the effect of reducing temperatures.

It is important to keep in mind that carbon dioxide spreads through the Earth’s atmosphere and stays there for a century or more, trapping heat on a global scale. Industrial aerosols stay relatively concentrated in the region where they are emitted and are often removed by rain and winds within a few weeks. So, their cooling effect doesn’t spread very far or last very long.

Overall, the initial pandemic slowdown probably didn’t have any real long-term impact on the climate but over the short term, the effects were not as simple as one might expect.

The Hottest September | Earth Wise

November 5, 2020 By EarthWise Leave a Comment

Here’s a news item that is like many other recent news items: September 2020 was the hottest September since 1880, according to the National Oceanic and Atmospheric Administration. The warm September is a part of a year that so far is poised to be at least the second hottest year in the 141-year climate record.

The ten warmest Septembers on record have all occurred since 2005, and the seven warmest Septembers have occurred in the past seven years.

So far, the year-to-date average global temperature has been the second warmest on record, being just 0.07 degrees Fahrenheit lower than the record year-to-date temperature set in 2016. Expectations are that 2020 will end up somewhere among the three warmest years on record for the globe.

September was warm in many places around the world. California and Oregon had their warmest September ever. Europe had its warmest September on record, Asia had its second warmest September on record as did Australia and South America.

So far, it has been the hottest year-to-date on record in Europe, Asia, and the Gulf of Mexico. No land or ocean areas anywhere had record-cold year-to-date temperatures.

Global temperatures represent an average over the entire surface of the planet. The fact that the global temperature is now nearly one Celsius degree above the 20th century average means that a vast amount of heat has been added in order to warm all the oceans, atmosphere, and land by that much. So, every uptick in global temperature is a big deal.

Meanwhile, the average Arctic sea ice coverage for September was the second smallest on record. The 14 smallest minimum annual sea ice extents have all occurred in the past 14 years.

Renewables Are Slowly Taking Over | Earth Wise

August 17, 2020 By EarthWise Leave a Comment

According to data released by the Federal Energy Regulatory Commission, wind, solar, and hydropower provided 100% of the 1.3 GW in new U.S. electrical generating capacity added in April 2020. Furthermore, the FERC report revealed that renewable sources accounted for 56% of the 9 GW added during the first four months of the year. Apart from renewables, the balance of new generation was almost entirely made up of new natural gas capacity. There have been no new capacity additions by coal, oil, nuclear power, or geothermal energy since the beginning of the year.

Renewable energy sources now account for nearly 23% of the nation’s total available installed generating capacity and continue to increase their lead over coal, which now accounts for only 20% of the nation’s electricity generation.

FERC data also suggests that renewables’ share of generating capacity should increase significantly over the next three years. So-called “high probability” generation capacity additions for wind, minus anticipated retirements, project a net increase of nearly 27 GW, while solar is projected to grow by 24 GW. By comparison, net growth for natural gas is expected to be just over 20 GW.

Hydropower, geothermal, and biomass are all expected to experience net growth while the generating capacity of coal and oil are expected to plummet. Nuclear power is forecasted to remain essentially unchanged.

In total, over the next three years, the mix of all renewables is predicted to add more than 50 times the net new generating capacity added by natural gas, coal, oil, and nuclear power combined. Renewables are truly on the rise.

Renewables Could Take Over By 2035 | Earth Wise

July 15, 2020 By EarthWise Leave a Comment

A study by UC Berkeley looked at the prospects for renewable energy sources to become the primary source of energy in the United States over the next 15 years. Even though fossil fuels continue to fill that role at present, the plummeting costs of alternative energy sources – primarily solar and wind power – are making them increasingly attractive on the competitive market.

These cost reductions have occurred much faster than what was anticipated even just a few years ago. According to the study, it is technically and economically feasible for renewable sources to provide 90% of our electricity by 2035.

The Berkeley researchers took the available data on renewable energy and created two scenarios for the next 15 years. The first has energy policy remaining as it is now, without ambitious policy changes that encourage the growth of renewable energy. In that scenario, they estimated that 55% of the US energy infrastructure would come from renewables. That amount will not produce the change needed to meet Paris Climate Agreement goals but would simply come about because of the dramatically lower costs for renewable energy.

The second scenario includes state and federal governments leading the way to finance and facilitate the energy reform needed for a greener 2035. It also relies on the large-scale use of grid-scale batteries to store the energy collected from solar and wind installations for when it is needed.

Which scenario is more realistic will depend on several major influential factors, notably the trajectory and consequences of the COVID-19 pandemic as well as the results of the November elections. These things will have a huge impact on the future of our energy system.

More Trouble For Monarchs | Earth Wise

April 14, 2020 By EarthWise Leave a Comment

Monarch butterflies have been in trouble for quite a while and now it seems like their prospects are worse than ever. Multiple surveys of butterfly populations are reporting plummeting numbers.

Western monarch butterflies spend their winters on the central California coast. Months later, they breed in California’s Central Valley and as far north and east as Idaho. But in recent years, it has become harder and harder to find them in their breeding sites.

The Western monarch population was in the millions in the 1980s. In 2017, an annual survey found 200,000 butterflies. In 2018 and 2019, only about 30,000 butterflies were tallied. The loss of Western butterflies in general has come about from a variety of factors, including development, climate change, farming practices and the widespread use of pesticides by farmers and on home and business lawns.

Scientists use the area of land that migrating Monarchs occupy in Mexico to gauge populations. This year, they covered about 7 acres, down from 15 acres in 2019.

Meanwhile, there are also far fewer Eastern monarch butterflies on the opposite side of the country. According to a new population survey, the Eastern monarch has passed the extinction threshold. Its population in 2020 dropped 53% from its already low 2019 numbers. Scientists were expecting lower numbers this year, but they were staggered by their findings.

Butterfly populations are quite variable, so it is possible that the drastic declines this year are not necessarily irreversible, but the news is not good. Researchers and environmental advocates continue to point out that mitigating the climate crisis, reducing pesticide use and planting pollinator gardens could help the butterflies to recover.

Building The World’s Largest Battery Energy Storage Plant | Earth Wise

April 6, 2020 By EarthWise Leave a Comment

The Monterey County Planning Commission has unanimously approved a joint project between Tesla and Pacific Gas and Electric to turn the Moss Landing Power Plant in California into the world’s largest battery energy storage facility.

The Moss Landing Power Plant is a natural gas-powered electricity generation plant located at the midpoint of California’s Monterey Bay. At one time, it was the largest power plant in the state of California with a generation capacity of 2560 MW but has been gradually shutting down over time.

The new facility will incorporate 1.2 GWh of storage capacity for energy generated by solar and wind systems. The stored energy will be available for use during periods of high energy demand and lower output. This is about ten times larger than Tesla’s Hornsdale energy storage project in Australia, which was three times bigger than any other batter storage facility when it was built a few years ago. In 2018, the battery system at Hornsdale made back a third of its cost in just one year. The systems make use of Tesla’s Megapack battery products which come in pre-assembled units that provide 3 MWh of energy storage capacity.

The project will make use of existing power lines to transmit energy around Monterey County and parts of Silicon Valley. Tesla and PG&E hope to break ground in early spring with completion scheduled for the end of the year. California has been adding massive amounts of wind and solar power to its electrical grid and incorporating energy storage is an important step towards creating a truly resilient power system.

A Record Antarctic Temperature | Earth Wise

March 5, 2020 By EarthWise Leave a Comment

It is still early in the year, but extreme weather events are already piling up. January was the warmest month on record globally and there have been many records shattered in Europe and Asia. A number of places in Eastern Europe, including parts of Russia, have seen temperatures 12 to 13 degrees above average.

While the warming of the Arctic has been in the news with increasing frequency, the Antarctic is also seeing rising temperatures and is one of the fastest-warming regions in the world.

On February 6th, Esperanza Base along Antarctica’s Trinity Peninsula measured a temperature of 65 degrees Fahrenheit, which is the highest temperature ever recorded on that continent. This rather balmy temperature narrowly beat out the previous record of 63.5 degrees, which occurred in March of 2015.

This one-time reading is certainly anomalous, and scientists say it is associated with a ridge of high pressure that was lingering over the region for several days. Local wind conditions led to additional warming.

However, the conditions leading to record-breaking high temperatures are not one-time anomalous events. Over the past 50 years, temperatures in the Antarctic have surged by an extraordinary 5 degrees in response to the Earth’s rapidly warming climate. A rise of five degrees in day-to-day weather is no big deal. A five-degree rise in a region’s average temperature is enormous.

About 87% of the glaciers along the west coast of Antarctica’s Trinity Peninsula have retreated over that 50-year period, most of which doing so during just the past 12 years.

Some researchers claim that the new temperature record is an extreme event that doesn’t tell us anything about the changing climate. Many others are convinced that there will be many more high temperature records to follow.

The Largest Community Solar Program

November 22, 2019 By EarthWise Leave a Comment

Community solar projects allow customers to benefit from the economic and environmental attributes of solar energy when they don’t have the ability to invest in their own system for any number of reasons.

Florida Power & Light company is proposing to build the largest community solar program in the United States, pending regulatory review. The planned installation of 1,490 MW of new solar capacity at 20 new power plants distributed across FPL’s service territory is expected to generate an estimated $249 million in net savings for all FPL customers over the long term.

In addition to becoming the largest community solar program in the country, the new program would also be the largest voluntary low-income solar offering in the country. Low-income households are typically unable to benefit from solar energy because of not having the means to invest in the technology. The new SolarTogether program will have more than 35 megawatts of capacity dedicated to low-income Florida families. Solar energy is a critical tool for enabling low-income families to tap into energy savings.

The SolarTogether program would provide direct savings in the form of bill credits, making solar an affordable option for any customer. The Southern Alliance for Clean Energy and Vote Solar joined with FPL to help design the program to include a low-income component and request Florida Public Service Commission approval. There is broad support for the program from universities, county and city governments, and private companies. In addition, more than 90,000 residential and small business customers have already signed up to receive more information. The utility hopes to receive regulatory approval in time to launch during the first quarter of 2020.

New Nutrition Labels

February 26, 2019 By EarthWise 1 Comment

Food and beverage packaging in this country has included a Nutrition Facts panel for nearly 25 years. Over 700,000 products have the labels which provide consumers with information like serving sizes, calories per serving, ingredients, and nutritional content.

Surveys indicate that 77 percent of all U.S. adults claim to use the labels at least some of the time. Whether the labels are actually useful is somewhat debatable. A couple of years ago, the FDA released a proposal to update the labels to make them more useful and to reflect more recent nutritional research. The new labels are finally going to be implemented and food manufacturers with annual sales exceeding $10 million have until January of 2020 to update their packaging with the new labels.

One of the biggest changes is that the “serving size” section of the label will be changed to more accurately reflect the actual portions consumed by the typical American. For example, a 20-ounce soft drink will now be labeled as a single serving because most people will drink the whole bottle in one sitting.

The new labels will no long list the amounts of Vitamin A and C, because recent research shows most Americans are not deficient in these nutrients. Instead, the amount of Vitamin D and potassium will be listed, two nutrients lacking in many diets. New labels will also show amounts of “added sugars”, defined as caloric sweeteners with no nutritional value. The new labels will also display the calories per serving in much large type making that piece of information far more noticeable.

There is surely more to be done to make food labeling more transparent and useful for consumers, but the new changes at least seem to be in the right direction.

Recycling And Olympic Medals

March 23, 2017 By EarthWise

Organizers of the Tokyo 2020 Olympic Games announced in February that all the Olympic medals for the games will be made from recycled materials. The strategic roadmap for the games, laid out in the document “Olympic Agenda 2020”, specifically calls for the inclusion of sustainability in every aspect of the games.
