Scientists say warm air caused the Larsen-B ice shelf to shatter in 2002. Unprecendented warm summers led to the collapse of over 1,000 square miles.

Futuristic 3-D Weather Graphics Grace the Weather Forecast for 2050
By: Dr. Jeff Masters
Published: 10 septembre 2014
Futuristic and creative 3-D weather graphics like you've never seen before light up the screen in today's impressive forecast for September 23, 2050 released by the Weather Channel. The video was made in response to an appeal by the World Meteorological Organization (WMO) to television weather presenters world-wide to imagine a “weather report from the year 2050,” based on the best science we have.
Climate Case Study: California Drought (2)

One of the problems I have with the press coverage is that this 63 trillion gallons and the change in the Earth’s crust is out of context of any other numbers. It is the first time the measurement has been made, not the first time there has been the change in the water sufficient enough to change the Earth’s elevation. There are also many pictures showing depleted reservoirs, again out of context. If one were so inclined, then one could find many inconsistencies and allusions, which would be open, potentially, to criticism of exaggeration. All of this is generated by the reportage on the paper on points that, to the best of my reading, were not made in the paper.

I can’t help but think of the carnivores finding the easy pickings of the herds collected around the drying water holes at what would become the Agate Fossil Beds. Then, from that, we don’t have to be beardogs. We humans are unique because of our ability to remember, to reason, to develop and to accumulate knowledge; we have the ability to make decisions that influence the future of our environment.
Wunderground's Climate Change Position
Based on the evidence, more than 97% of climate scientists have concluded that human-caused climate change is happening. Climate change is already causing significant impacts to people and ecosystems, and these impacts will grow much more severe in the coming years. We can choose to take economically sensible steps to lessen the damage of climate change, and the cost of inaction is much higher than the cost of action.

Earth Has its Warmest Summer and August on Record

August 2014 and the summer of 2014 were Earth's warmest since records began in 1880. Global ocean temperatures during August 2014 were the warmest on record, and the 0.65°C (1.17°F) ocean temperature anomaly was the highest ever measured, beating the record set just two months previously in June 2014. The first eight months of 2014 (January–August) were the third warmest such period on record for the globe.
