Climate change: Nearly 700 'natural thermometers' demonstrate the world is warmer than its ever been.

In the most comprehensive assessment of how the climate has changed over the period to date, researchers looked at a host of sources of historic information, including tree rings, ice cores, lake and sea sediments, corals, mineral deposits and written records.


Scientists have found evidence that wildfires, like
 this one near Clayton, California, have been getting
worse because of climate change 
Planet Earth is warmer than it has been for at least 2,000 years, according to a study that took its temperature from 692 different “natural thermometers” on every continent and ocean on the planet.

What they found confirmed the famous “hockey stick” graph, showing an undulating, but broadly flat, line followed by a sharp uptick that begins at around 1900.
