Twenty-three million years ago, the Antarctic Ice Sheet began to shrink, going from an expanse larger than today's to one about half its modern size. Computer models suggested a spike in carbon dioxide levels as the cause, but the evidence was elusive - until now. Ancient fossilized leaves ...
(Phys.org) —For the first time in human history, concentrations of the greenhouse gas carbon dioxide (CO2) could rise above 400 parts per million (ppm) for sustained lengths of time throughout much of the Northern Hemisphere as soon as May 2013. To provide a resource for understanding the...
The calculated price should decrease as we move back in time to take into account that carbon dioxide is a stock pollutant, and that one unit added to the present large stock is likely to cause more damage than a unit emitted under the lower concentration levels in the past. We incorporate...
Understanding Carbon Footprint Calculating your carbon footprint can help you understand your individual impact on greenhouse gas emissions. This footprint includes the carbon dioxide and other greenhouse gases you produce through daily activities such as driving, electricity use, and waste generation. By...
The Inflation Reduction Act is expected to cut roughly a billion tons of greenhouse gas emissions a year by 2030, save thousands of lives a year, and prompt a transformation of the U.S. energy and transportation landscape.
Gases like carbon dioxide are also absorbed into the ocean. This makes the ocean temperature rise. It can also make the ocean more acidic. Gaston Browne is the prime minister of Antigua and Barbuda. This is one of the cou...
Better still, it has reduced greenhouse gas emissions by 13,403 tons of carbon dioxide (80 percent) per year. “We expect the savings to continue to increase as we extract more consumption data from the operation and analyze why reductions have occurred,” says Savall. “Using the ...
protect and improve our water resources; and invest in climate change mitigation projects that will reduce pollution and lower carbon emissions. The Bond Act will also support a substantial investment in the Clean Green Schools initiative that will reach every public school located in a disadvantaged...
In the historic center of the city of Cuenca, Ecuador, during the period January-August of 2020, the total sum of carbon monoxide for restriction without traffic light 1 is 7.4779 mg/m3 and the number of infected is 13. This period has the lowest levels of contamination due to the appeara...
Researchers also evaluated whether increases in renewable energy resources, like wind and solar energy, could help prevent increases in emissions of carbon dioxide from power generation during drought in the future. "Usually what happens in California during a drought is they have to turn on natural...
