The Pacific’s Ring of Fire is being Wracked by Powerful Earthquakes: Could California’s “Big One” be Far Behind?
A series of 70 major earthquakes that have occurred around the Pacific Ocean’s Ring of Fire has prompted fears that California may be hit by the dreaded "Big One", an anticipated earthquake with a magnitude powerful enough to have catastrophic consequences for the state. The sequence of earthquakes struck Indonesia, Bolivia, Japan and Fiji, but so far no major seismic activity has been reported in California. But could this recent rash of earthquakes mean that the "Big One" could be close behind?

Melting Arctic May be Cause of Drop in Tornadoes
It mightn’t be quite a case of the flapping of a Brazilian butterfly’s wings causing a tornado in Texas, but a team of climate researchers has found a correlation between melting Arctic sea ice and the formation of tornadoes in the United States, with fewer tornadoes being reported when northern sea ice is unseasonably low.
"A relationship between Arctic sea ice and tornadoes in the US may seem unlikely," says study co-author Jeff Trapp, an atmospheric sciences researcher with the University of Illinois at Urbana. "But it is hard to ignore the mounting evidence in support of the connection."

Hothouse Earth: It’s Getting Too Warm Too Fast
Despite the pledges and measures being taken to address the rising concentrations of atmospheric carbon dioxide, CO2 levels continue to climb. This trend is causing concern amongst climate researchers, including worries that limiting global warming’s effects to two degrees Celsius, as per the Paris Agreement, might still trigger a cascade effect that would lead to a "Hothouse Earth" situation that we would have no control over.
