WASHINGTON DC - Concentrations of carbon dioxide in the atmosphere in May were 50 percent higher than during the pre-industrial era, reaching levels not seen on Earth for about 4 million years, the main US climate agency said on Friday. Global warming caused by humans, particularly through the production of electricity using fossil fuels, transport, the
NEW YORK - Humans' historical greenhouse gas emissions have caused the climate crisis the world is in today. But it's the amount emitted now and in coming years that will determine whether humanity can avert catastrophic climate changes. That's the main finding of a new study published in the journal Nature Climate Change on Monday, which
TOKYO, Japan - A team of researchers led by Professor Seiji Yamazoe at the Tokyo Metropolitan University has developed a new direct air capture method to trap carbon dioxide. It works with 99 percent efficiency, a Eureka Alert press release said. The world is transitioning to cleaner sources of energy. However, the transition is prolonged, and
DETROIT - For the last 100 years, the leading method for carbon capture in chemistry has been a process known as amine scrubbing. Amines are organic, ammonia-derived compounds that contain nitrogen. In an aqueous solution, they are able to selectively remove carbon dioxide from gas mixtures. However, oxygen degrades them every time they're cycled, which means that more
DETROIT - A new study, published today in Nature Climate Change, will certainly make the IPCC—and other environmental bodies—take notice. A team of scientists led by Dr. Rei Chemke of Weizmann's Earth and Planetary Sciences Department revealed a considerable intensification of winter storms in the Southern Hemisphere. The study, conducted in collaboration with Dr. Yi Ming of
DETROIT - Water scarcity is a growing problem around the world. Desalination of seawater is an established method to produce drinkable water but comes with huge energy costs. For the first time, researchers use fluorine-based nanostructures to successfully filter salt from water. Compared to current desalination methods, these fluorous nanochannels work faster, require less pressure
DETROIT - The power of the wind has been harnessed for millennia and began to be used for electricity generation in the late 1800s and early 1900s before the advent of rural electrification. The oil shortages of the 1970s sparked a comeback. Small power-generating windmills, called turbines, were constructed as something of a novelty, usually
DETROIT - A new study by scientists from British Antarctic Survey (BAS) has used computer modeling to rank the factors responsible for the Larsen C ice shelf melt according to their severity. The review is an important contribution to our understanding of the largest remaining ice shelf on the Antarctic Peninsula. Research into Larsen C
WASHINGTON DC - The United Nations’ climate change panel is calling for a “substantial reduction” in the global use of fossil fuels in order to avoid the worst impacts of climate change. Warning there is limited time to act, the latest report from the panel says that by 2030, greenhouse gas emissions need to be
WASHINGTON — The Biden administration on Monday proposed strict new limits on pollution from buses, delivery vans, tractor-trailers and other heavy trucks — the first time in more than 20 years that tailpipe standards have been tightened for the biggest polluters on the road. The new draft rule from the Environmental Protection Agency would require
