Nearly 70% of U.S. oil consumption is for transportation and transportation accounts for 28% of the country’s greenhouse gas emissions.  Therefore, technology improvements in transportation that can reduce emissions are a key element of combating climate change.  The highest impact strategy is the electrification of the transportation sector, and it is definitely accelerating. Demand for […]

A research team led by scientists at UCLA have developed a super-white paint that reflects as much as 98% of incoming heat from the sun.  Such paint, if used on rooftops and other parts of buildings, could have a major impact on reducing the costs of keeping buildings cool. Passive daytime radiative cooling is a […]

In late July, the two houses of the New York legislature passed a number of environmental bills covering a wide range of topics. These included a bill to add protected status for streams that support fisheries and non-contact recreation.  A second bill bans the use of PFAS in food packaging.  A third bill classifies all […]

The domestication of cows, pigs, chickens, and other animals as livestock for their meat, milk, and eggs was historically revolutionary.  It boosted food security by giving people a readily-available means of feeding themselves as opposed to more traditional methods such as hunting and fishing.  But animal agriculture has plenty of drawbacks.  The industrialization of animal […]

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 […]

Major automakers as well as dedicated specialized companies are actively developing autonomous vehicle technology.  Many cars already offer varying degrees of self-driving capability.  These vehicles have a variety of sensor systems that allow them to detect other objects on the road.  Many rely on lidar or on cameras using visible or near-infrared light and these […]

Last year, we talked about the troubles facing the Colorado River.  Nearly two decades of drought conditions have reduced the water levels of the two largest reservoirs of Colorado River water and have threatened the water supply of millions of people in the region.  Clear scientific evidence shows that climate change is constricting the iconic […]

The California condor is the largest North American land bird.  Its wingspan is nearly 10 feet and its weight of up to 26 pounds nearly equals that of the trumpet swan, the heaviest native North American bird.  California condors can live up to 60 years, making them among the world’s longest-living birds as well.  But […]

PFAS, short for poly and perfluoroalkyl substances, have been used in commercial products since the 1940s.  There are more than 4,000 different chemicals in the class.   Some of the most commonly used PFAS chemicals, like PFOS and PFOA, have long half-lives, which has earned them the moniker “forever chemicals.”  These dangerous chemicals have not been […]

According to a study led by researchers at Ohio University, the South Pole has warmed more than three times the global average over the past 30 years.  While the warming was driven by natural tropic climate variability, the researchers argue that rising greenhouse gas emissions likely intensified the warming.  The climate in the antarctic has […]
