There have been decades of government support for renewable, crop-based fuels – primarily corn ethanol. In fact, it is a required component of gasoline sold in this country. The biofuels industry has long claimed ethanol to be a clean, greene
Temperature extremes on Earth currently range from a low of -129°F to a high of 134°F. But these climatic limits have changed throughout history. In fact, during the last interglacial period 130,000 years ago, temperatures were warmer, resemb
Scotland, and the UK in general, used to suffer from sulfur dioxide pollution. Industrial and domestic emissions, especially from burning coal, contributed heavily to urban air leading to the London smog of the 1950s and the acid rain of the 1
Many industrial processes require extremely high temperatures, typically more than 1,800 degrees Fahrenheit. This heat is generally produced by burning fossil fuels – either coal or natural gas – which emits large amounts of greenhouse gases.
There are about half a million school buses in use in the U.S. A large number of them are older, highly polluting diesel buses. There are well-established health and climate benefits of switching from diesel vehicles to electric vehicles but
Scientists have been sounding the alarm on the global struggle of pollinators for decades. Many recent studies have highlighted alarming declines in pollinator populations, sparking concern about the potential negative impacts on ecosystems an
There are about 18,000 desalination plants around the world that take in 23 trillion gallons of water each year. The plants produce more than 37 billion gallons of brine – enough to fill 50,000 Olympic-size swimming pools – every day. Disposi
There seems to be no end to the types of pollution we have introduced into the environment. One that has only recently started to gain attention is pollution caused by vehicle tires. Through normal wear and tear, as vehicles drive along roadw
Despite the increasing concern about the warming climate, the period between March of last year and March of this year has set a new record for the largest 12-month gain in atmospheric CO2 concentration ever observed. The new level, measured a
There are nearly 200,000 glaciers in the world. About 91% of them are in Antarctica and 8% in Greenland. The rest are scattered across nearly 50 countries. The non-polar country with the most glaciers is actually Pakistan, which has over 7,2
Concrete is the second-most-used material on the planet. Only water is used more. Producing concrete is responsible for 7.5% of human-produced carbon dioxide emissions. So, finding a cost-effective way to reduce these emissions is a major ch
For the past 10 years, there have been several occurrences of a vast expanse of ocean stretching from Alaska to California in which water temperatures are as much as 7 degrees Fahrenheit warmer than normal. Known jocularly as “the Blob,” the p
The past 12 months have been the hottest ever measured across the globe. This may not be everyone’s experience in every location, but the average person on Earth experienced 26 more days of abnormally high temperatures than they would have in
Olive oil is a liquid fat obtained by mashing whole olives and extracting the oil. A superfood staple of the Mediterranean diet, olive oil is used in kitchens around the world for frying, sauteing, baking, and as a condiment. It can also be w
Solar geoengineering is a type of climate intervention: deliberate actions designed to affect the climate. There are several ways to try to reduce the amount of sunlight reaching the surface of the earth and all of them are controversial. Pe
Using solar and wind power can go a long way toward replacing fossil fuel-generated electricity, particularly with the addition of battery energy storage. But because of the intermittent nature of both sun and wind, other sources are still nee
The combination of a warming climate and human disruption of traditional habitats has been causing changes in the ranges of many animal species. Over the past century, white-tailed deer have greatly expanded their range in North America. Rese
California has aggressively pursued the use of renewable energy, particularly solar and wind power. Last year, renewables supplied 54% of the state’s electricity needs. This year, California has been achieving some remarkable milestones with
Direct air capture (DAC) is process that removes carbon dioxide out of the air and stores it away where it can no longer trap heat in the atmosphere. It is intended to be a way of getting rid of the greenhouse gases that have built up in the a
If you are seeing fewer fireflies each year, you’re not alone. Like many insects, firefly populations are in decline. A new study by researchers from the University of Kentucky, Bucknell University, Penn State University, and the USDA has she
There has been lots of talk recently about the transition to electric vehicles sputtering out. Several automakers have delayed their EV programs citing reduced demand for the vehicles and lack of profitability. In the bigger picture, the auto
About 40% of the world‘s population lives in coastal regions. People really like ocean-front property. But worldwide, rising sea levels mean that more and more people want to live on land that may someday be swallowed up by the sea. One possi
Emperor penguins, the tallest and heaviest of all living penguins, are also the most famous, being the subject of a very popular documentary film. The ongoing loss of sea ice in Antarctica has led to unprecedented breeding failures in emperor
For the past several years, the Swiss-based company Energy Vault has been developing an energy storage system based on the principle of using mechanical devices to lift heavy concrete blocks into stacks using power generated by wind turbines or
Palm oil is the world’s cheapest and most widely used vegetable oil. In fact, more than 86 million tons of palm oil was consumed last year alone. Even though few of us cook with it, palm oil can be found in approximately half of all packaged
