-Down to Earth By 2080, Greenhouse gases are expected to raise the risk of extreme wildfire by 50%, according to the study Greenhouse gas (GHG) emissions and air pollution caused by human activities had distinct regional impacts on extreme outbreaks of wildfire, according to a new study conducted by the University of California Santa Barbara in the United States. The study examined the weather under various combinations of human influences since 1920, isolating...

-Down to Earth Study highlight need to use sustainable management to preserve and enhance soil carbon storage of grasslands. A new study shows that emissions of methane (CH4) and nitrous oxide (N2O) from grasslands increased by a factor of 2.5 since 1750 mainly due to increased emissions from livestock. This has more than compensated for reduced emissions from the shrinking number of wild grazers, said the study published in Nature Communications. The net...

-Down to Earth 43% of total emissions of nitrous oxide, a greenhouse gas 300 times more potent than carbon dioxide, came from human sources, the report said Human emissions of nitrous oxide (N2O) — a greenhouse gas 300 times more potent than carbon dioxide (CO2) — increased by 30 per cent between 1980 and 2016, according to a research paper published in Nature October 7, 2020. Nitrous oxide is a dangerous gas for...

-The Hindu Leaders should act on the climate crisis with the same alacrity they have shown towards COVID-19 Two interrelated curves began their upward trend two centuries ago with the advent of the industrial age. The first curve was the atmospheric concentration of carbon dioxide (or, more generally, all Greenhouse gases, GHGs) and the second was the average global temperature curve. An upward trend Actually, the CO2 curve began its upward march about 18,000...

-Down to Earth Rising temperatures due to climate change may be compounding the stress on crops in multiple ways, it says Insect attacks are becoming stronger with rising temperatures and plants are not able to cope with the double whammy from pests and rising heat. These are the findings of a recent study published in the journal Proceedings of the National Academy of Sciences. The study reinforces previous findings that persistent warm and...
