Year begins with warmest January despite shift toward cooling La Nina

Define pre-industrial times on the graph here:

That would be all the graph, what do you think you are proving by presenting something at a completely wrong scale? the current changes are being noticed at a scale of single years, not thousands of them. Pretending previous ages somehow make the current changes "natural" or "innocuous" is like pretending there is nothing wrong with pouring boiling water onto someone because the hydrogen and oxygen that make that water have been at thousands or degrees before.

Japan in January was colder than normal in Kyushu but milder than normal in Hokkaido.

Snow was also a mixed bag, less in some snowy places but others also got hammered. While regional differences always happen, they've been more extreme than normal. As witnessed by the price of cabbages, for example.

The graph above highlights how extreme climate can be as the world's natural systems react to big changes - snowball earth, mass CO2 drawdown when continents and plants evolved etc. And the speed of the current climate changes are VERY fast in terms of geological time and give us and much of nature little chance of adapting.

Who will tell the people in Western Japan, that the snow they are digging out of just now is just an illusion, since

"snow is starting to disappear from our lives, within a few years winter snowfall will become a very rare and exciting event. Children just aren't going to know what snow is".

(According to Dr. David Viner, a senior research scientist at the climatic research unit (CRU) of the University of East Anglia, published in "The Independent" March 20. 2000.)

Invalid misrepresentation, climate change is well described to come with extreme local variations. That the end product will make snow much rarer do not mean it will do it gradually and homogeneously around the planet.
