Methane meltdown, global warming will accelerate
Yet Global Warming has hit a critical threshold which has made even some thought leaders in the space wonder if it's still reversible. Troubling new signs of a collapse are occurring, beyond the periodic reports of large disappearing swaths of ice. Now, boosted by increasing temperatures, frozen methane is thawing. Note that the further from the equator, the more extreme warming has become:
Why do we care about methane? For one, it's about 21 times more potent a greenhouse gas than CO2. And there's a lot of it in a frozen state in areas which have crossed or are near a threshold temperature. As well, there are other greenhouse gases we need to worry about, including Nitrogen trifluoride (NF3), which ironically results from the manufacturing of thin-film photovoltaic cells. NF3 is 17,000 times more potent a greenhouse gas than CO2!
"Springtime air temperatures on the East Siberian Arctic shelf [have] increased up to 5 degrees Celsius [9 degrees Fahrenheit]," Semiletov said. "It's a hot spot."
In comparison, the world as a whole has warmed about 1.25 degrees Fahrenheit (0.7 degrees Celsius) since pre-industrial times.
