Krafla is one of the most explosive volcanoes in Iceland, which is home to many active volcanoes, including one recently in the news near Reykjavik that hadn’t erupted for 800 years .  Krafla is the site of the Krafla Magma Testbed, which may end up being for geoscientists what the Large Hadron Collider has been […]

Researchers predict that climate change will negatively impact the yield and nutritional quality of most staple food crops, including rice, corn, and soybeans, due to factors like extreme weather events, rising temperatures, and altered precipitation patterns, potentially leading to reduced food security globally.    As a result, many experts contend that alternative food sources – like […]

One of the largest solar projects in the US has recently come online in Texas.  Three solar farms built side-by-side in Buckholts, Texas by SB Energy can provide 875 megawatts of electricity, nearly the size of a typical nuclear power plant.  The project will supply the largest solar energy purchase ever made by Google and […]

Wildlife trafficking is the world’s fourth largest form of organized crime, behind only drug trafficking, counterfeiting, and human trafficking.  When we hear about wildlife trafficking, we think of elephant ivory, rhino horns, tiger parts, and the like.  But so-called forest crimes, which includes poaching protected trees and illegal logging added up to somewhere between $30 […]

People’s views and level of concern about climate change tend to vary according to age, political affiliation, and other demographic categories.  But one clear trend is that young people are overwhelmingly concerned about climate change.  Given that they will ultimately suffer from its effects far more than older generations, this is not really surprising. A […]

The US is the world’s largest user of nuclear power.  Its 94 reactors supply nearly 19% of the country’s electricity. But the number of U.S. reactors has steadily fallen over the past 30 years and new nuclear power plants are a real rarity.  The reasons are a combination of perceived dangers following several nuclear accidents […]

According to the U.S. Department of Energy, the United States is the world’s largest producer of natural gas.  In fact, natural gas supplies approximately one third of the United States’ primary energy consumption, most of which is used to heat buildings and to generate electricity.  While most natural gas is delivered in its gaseous form […]

Cement production accounts for about 7% of global carbon emissions.  It is one of the most difficult challenges for emissions reduction.  The emissions associated with producing cement come from both the energy used to provide heat for the process and from the chemical reactions that take place in the formation of cement.  Cement is an […]

Vast areas of South America have been gripped in drought conditions for months.  Rivers in the Amazon basin fell to record-low levels in October.  The drought has amplified wildfires, parched crops, disrupted transportation networks, and interrupted hydroelectric power generation in parts of Brazil, Bolivia, Colombia, Ecuador, Peru, and Venezuela. The drought is related to the […]

Arctic sea ice has shrunk to near-historic lows during this Northern Hemisphere summer.  The minimum extent for the year occurred on September 11th.  Ice cover in the Arctic Ocean has been shrinking and thinning for more than 40 years.  The amount of frozen seawater in the Arctic goes up and down during the year as […]
