There is no consensus that Human activity drove the warming from 1900 to 1998. It only exists among Western scientists, who are now the second tier scientists in the world, behind Russia and China, apparently.
Cold sun rising - The Nation
The sun will go into "hibernation" mode around 2030, and it has already started to get sleepy. At the Royal Astronomical Society's annual meeting in July, Professor Valentina Zharkova of Northumbria University in the UK confirmed it - the sun will begin its Maunder Minimum (Grand Solar Minimum) in 15 years. Other scientists had suggested years ago that this change was imminent, but Zharkova's model is said to have near-perfect accuracy.
So what is a "solar minimum"?
Our sun doesn't maintain a constant intensity. Instead, it cycles in spans of approximately 11 years. When it's at its maximum, it has the highest number of sunspots on its surface in that particular cycle. When it's at its minimum, it has almost none. When there are more sunspots, the sun is brighter. When there are fewer, the sun radiates less heat toward Earth.
But that's not the only cooling effect of a solar minimum. A dim sun doesn't deflect cosmic rays away from Earth as efficiently as a bright sun. So, when these rays enter our atmosphere, they seed clouds, which in turn cool our planet even more and increase precipitation in the form of rain, snow and hail. ...
Around 2000, the PDO Index started to blow cold again, possibly causing global warming to "pause", as the mainstream scientists describe it. IPCC-affiliated scientists as well as Nasa and the NOAA attribute the pause to other factors. This is when the plot thickens.
Solar cycle 24 - two cycles prior the cycle that's expected to bottom out into a Maunder Minimum - was weak. In 2013-14 it reached its maximum far below average. Meanwhile extreme cold-weather anomalies have occurred around the world. Last year "polar vortices" slammed into the central US and Siberia as a third hovered over the Atlantic. All 50 US states, including Hawaii, had temperatures below freezing for the first time in recorded history. Snowfall records were broken in cities in the US, Canada, Italy, New Zealand, Australia, Japan and elsewhere. Southern American states and central Mexico, where snow is rare, got heavy snow, as did the Middle East.
This past summer the cold didn't let up, with more temperature records across the US and rare summer snows seen in Canada, the US and China. Birds have migrated early in the last two years. Antarctic sea ice set a new record in 2013 and it was broken again in 2014.
Not even Thailand was immune. In 2014 Bangkok hit its coldest low in 30 years, while 63 lives were lost in the North.
Scientists at the Climate and Environmental Physics and Oeschger Centre for Climate Change Research at the University of Berne in Switzerland have recently backed up theories that support the sun's importance in determining the climate on Earth. A paper published last year by the American Meteorological Society contradicts claims by IPCC scientists that the sun couldn't be responsible for major shifts in climate. Judith Curry, chair of the School of Earth and Atmospheric Sciences at the Georgia Institute of Technology, rejected IPCC assertions that solar variations don't matter. Among the many studies and authorities she cited was the National Research Council's recent report "The Effects of Solar Variability on Earth's Climate".
Other researchers and organisations are also predicting global cooling - the Russian Academy of Science, the Astronomical Institute of the Slovak Academy of Scientists, the Institute of Terrestrial Magnetism Russia, Victor Manuel Velesco Herrera at the National University of Mexico, the Bulgarian Institute of Astronomy, Dr Tim Patterson at Carleton University in Canada, Drs Lin Zhen at Nanjing University in China, just to name a few.
For now nevertheless, the IPCC and other authoritative agencies are sticking to their CO2-dominant climate-forcing theory. They attribute the cold spells to a disruption in the jet stream caused by Anthropogenic Global Warming. Some of their theories have heads being scratched, for instance the "pause" in global warming they attribute to heat being absorbed deep into the oceans. When Antarctic ice reached record levels in 2013, scientists were "baffled" because the water beneath the ice was warm, they claimed. In climate science old and new, nothing is certain.
