Some wetlands are a significant source of methane emissions [6] [7] and some are also emitters of nitrous oxide. [8] [9] Nitrous oxide is a greenhouse gas with a global warming potential 300 times that of carbon dioxide and is the dominant ozone-depleting substance emitted in the 21st century. [10] Wetlands can also act as a sink for greenhouse ...
BAKU (Reuters) -The world's warming tropical wetlands are releasing more methane than ever before, research shows — an alarming sign that the world's climate goals are slipping further out of reach.
Tropical Storm Alberto making landfall in Florida in 1994; Alberto became the costliest tropical cyclone in the history of Georgia October 12–14, 1990 – The remnants of Tropical Storm Marco and moisture from the remains of Hurricane Klaus combine, producing heavy rainfall in Georgia, peaking at 19.89 inches (505 mm) near Louisville .
[109] [110] [111] Shakhova et al. (2008) estimate that not less than 1,400 gigatonnes of carbon is presently locked up as methane and methane hydrates under the Arctic submarine permafrost, and 5–10% of that area is subject to puncturing by open talik. Their paper initially included the line that the "release of up to 50 gigatonnes of ...
However, 2022 research by the same team which had originally discovered this peatland not only revised its area (from the original estimate of 145,500 square kilometres (56,200 sq mi) to 167,600 square kilometres (64,700 sq mi)) and depth (from 2 m (6.6 ft) to (1.7 m (5.6 ft)) but also noted that only 8% of this peat carbon is currently covered ...
In the United States, a tropical storm watch was posted on July 2 for locations between Sabine Pass, Texas and Pensacola, Florida. The watch was subsequently upgraded to a tropical storm warning from Gulfport, Mississippi, to Cedar Key, Florida; it was soon altered to a hurricane warning. Later on July 3, the hurricane warning was discontinued ...
A "greenhouse Earth" is a period during which no continental glaciers exist anywhere on the planet. [6] Additionally, the levels of carbon dioxide and other greenhouse gases (such as water vapor and methane) are high, and sea surface temperatures (SSTs) range from 28 °C (82.4 °F) in the tropics to 0 °C (32 °F) in the polar regions.

ATLANTA (Reuters) -Hoax bomb threats, many of which appeared to originate from Russian email domains, were directed on Tuesday at polling locations in five battleground states - Georgia, Michigan ...
