A significant rise in temperature, not the increase of 0.8 degrees C,which is not enough to justify the current warming fraud. And by the way temp. measuring devices were not very accurate 100 years ago, so the rise of even 0.8 degrees in 100 years is suspect.
Ice core samples that go back thousands of years, can all be analysed by today's standards of accuracy , and all show a steep acceleration in global warming since the industrial revolution.
