The past year has brought new evidence that climate change is already beginning to damage the habitability of our planet. This year scientists have concluded that numerous long-term or mega-droughts are the result of man made climate change. Top scientists concluded that humanity may be close to a tipping point.

This year saw the lowest recorded sea-ice, the lowest recorded snow cover extent and duration, and the most extensive recorded melting event on the surface of the Greenland ice sheet.

A World Bank report concluded that a 4 degree Celcius rise in the average global temperature would be disaster while scientists believe in the next century temperatures may rise as much as 8 degrees. This year scientists also concluded that humans have caused dramatic tropospheric and stratospheric temperature changes.

A new US climate change report by the U.S. Geological Survey, the National Wildlife Federation and Arizona State University in Tempe found evidence of fish, plant and animal population declines and increased extinction risks, cascading effects through ecosystems that are causing dramatic changes in geographical fauna and floral throughout the U.S. In addition, the timing of flowering, laying eggs or migrating has changed throwing ecosystems into chaos. This is lowering the quality of drinking water, increasing pest control problems, reducing crop yields, and increasing erosion.

Another report indicated that that 100 million will die in the next twenty years as a result of climate change. Damages to agriculture and fisheries could cost $500 billion on year by 2030.

The third draft of U.S. Climate Assessment envisions hard times for the US. The report written by 240 scientists suggests that climate change will hit the U.S. hard with flood causing and erosive rains in the Northeast, Midwest and Plains, sea level increases that will destroy coastal communities and widespread fire producing and crop destroying droughts in the West. The report concludes that this isn’t a future scenario but the current situation and it states that it is being caused by humans.

The acidity of seawater has become so bad it’s dissolving sea snails and shells and coral that constitute a substantial part of humanity’s food supply.
