Peter Sinclair has been putting out great videos for years on climate change as Climate Crock of the Week. They focus on having a close look at climate change deniers claims.
The following video looks at a series of talking heads claiming that the world is cooling. Such a pity that their own favorite crank on data appears to be finding that the La Nina of 2010 had such a short effect on global climate patterns. In fact it looks like it was trying to impose itself on a long term trend of warming, and really having little effect except during a very limited period at its peak.
What is notable about this video is that it pulls material in from the 1950’s to the present with scientists pointing out the consequences of our inadvertent experiment in large scale atmospheric modification. Looking at the emerging pattern of extreme weather events, it looks like those decades of wasted opportunities to correct the problem have given way to the decades of consequences.
Everywhere we look, impacts are coming faster and harder than we would have predicted just a few years ago.
The change that is happening to climate in the temperate zones like NZ is that the weather patterns are getting more extreme as the differences in energy stored in the atmosphere and oceans steadily increases. It doesn’t particularly change our average temperatures, winds and rainfall. We are islands surrounded by moderating ocean with its slow currents. But our weather events just get more intense as more cold air masses escape further north and warm air masses mover further south.
