Fire Earth

Earth is fighting to stay alive. Mass dieoffs, triggered by anthropogenic assault and fallout of planetary defense systems offsetting the impact, could begin anytime!

A huge sandstorm engulfs the Saudi capital of Riyadh, Saudi Arabia, Tuesday, March 10, 2009. The storm, which was still raging hours after it started, disrupted flights at the city’s King Khalid International airport, with weather authorities announcing that visibility would drop to zero, and warning residents to take precautionary measures.

Human-induced Climate Change

Posted by feww on February 25, 2008

“Dust fall” in the West in the last 100 years is up to seven times heavier than at any period in history.

Human activities such as settlement, railroad, industry, farming and ranching has caused a huge increase in the dust levels in the air, according to a report by the University of Colorado at Boulder.

“The chemical composition of the dust is changing. And it’s changing in a way that we actually see the byproducts of both industrial activity and agricultural activities in the dust. We see elevated phosphorous and we see elevated nitrogen in these lake sediments,” said Neff of the University of Colorado at Boulder, who led the study.

According to another study, published in January, human-caused climate change has altered river flows, snow pack and air temperatures.

“The dust we see in these lakes is the same dust that causes earlier spring snowmelt here, so we can now definitively say that humans are in large part responsible for this melt,” said Neff.
