For years, RSS have been an embarrassment to the climate establishment. Their satellite data has consistently shown the pause in global temperatures since 1998, which so many scientists have attempted to explain.
At the same time, the surface datasets of GISS, NOAA and HADCRUT have diverged, with the help of adjustments, to show much greater warming.
The pressure on RSS to conform has been immense, and now the inevitable has happened. Highly conveniently they have found huge errors in their previous version, and have now adjusted to a new version, v4, which miraculously finds that global warming has continued unabated after all!

Carbon dioxide truly is “the gas of life.” The plants that feed us and wildlife can’t live without inhaling CO2, and then they exhale the oxygen that lets humans and animals keep breathing.
Our crop plants evolved about 400 million years ago, when CO2 in the atmosphere was about 5000 parts per million! Our evergreen trees and shrubs evolved about 360 million years ago, with CO2 levels at about 4,000 ppm. When our deciduous trees evolved about 160 million years ago, the CO2 level was about 2,200 ppm – still five times the current level.

Statistician Bjorn Lomborg had already pointed out that the Paris CO2 emission promises would cost $100 trillion dollars that no one has, and make only a 0.05-degree difference in Earth’s 2100 AD temperature. Others say perhaps a 0.2 degree C (0.3 degrees F) difference, and even that would hold only in the highly unlikely event that all parties actually kept their voluntary pledges.
