Globe is warming at 0.2°C per decade.
Seems less according to REMSS and UAH.

Most of your “predictions” have not been made by scientists.
"1. Warming rate predictions
1990 IPCC FAR: “Under the IPCC ‘Business as Usual’ emissions of greenhouse gases the average rate of increase of global mean temperature during the next century is estimated to be 0.3°C per decade (with an uncertainty range of 0.2°C – 0.5°C).”
2. 1990 IPCC FAR: “Under the IPCC ‘Business as Usual’ emissions of greenhouse gases … this will result in a likely increase in global mean temperature of about 1°C above the present value by 2025.”
3. Winter predictions
2001 IPCC TAR (AR3) predicts that milder winter temperatures will decrease heavy snowstorms,
4. Snow predictions
2000 Dr. David Viner, a senior research scientist at the climatic research unit (CRU) of the University of East Anglia, predicts that within a few years winter snowfall will become “a very rare and exciting event”. “Children just aren’t going to know what snow is.”
2004 Adam Watson, from the Centre for Ecology and Hydrology in Banchory, Aberdeenshire, said the Scottish skiing industry had no more than 20 years left.
5. Precipitation predictions
2007 IPCC AR4 predicts that by 2020, between 75 and 250 million of people are projected to be exposed to increased water stress due to climate change. In some countries, yields from rain-fed agriculture could be reduced by up to 50%.
6. Extreme weather predictions
2010 Dr. Morris Bender, from NOAA, and coauthors predict that “the U.S. Southeast and the Bahamas will be pounded by more very intense hurricanes in the coming decades due to global warming.” They say the strongest hurricanes may double in frequency.
7. Wildfire predictions
2001 IPCC TAR (AR3) said that fire frequency is expected to increase with human-induced climate change, and that several authors suggest that climate change is likely to increase the number of days with severe burning conditions, prolong the fire season, and increase lightning activity, all of which lead to probable increases in fire frequency and areas burned.
8. Rotation of the Earth predictions
2007 Dr. Felix Landerer of the Max Planck Institute for Meteorology in Hamburg, Germany, published a study predicting that Global warming will make Earth spin faster. See here.
2015 Dr. Jerry Mitrovica, professor of geophysics at Harvard University finds out that days are getting longer as the Earth spins slower, and blames climate change.
9. Arctic sea ice predictions
2007 Prof. Wieslaw Maslowski from Dept. Oceanography of the US Navy predicted an ice-free Arctic Ocean in summer 2013, and said the prediction was conservative.
2007 NASA climate scientist Jay Zwally predicted that the Arctic Ocean could be nearly ice-free at the end of summer in 2012.
2008 University of Manitoba Prof. David Barber predicted an ice-free North Pole for the first time in history in 2008.
2012 Prof. Peter Wadhams, head of the polar ocean physics group at the University of Cambridge (UK), predicted a collapse of the Arctic ice sheet by 2015-2016.
10. Polar bear predictions
2005 The 40 members of the Polar Bear Specialist Group (PBSG) of the World Conservation Union decided to classify the polar bear as “vulnerable” based on a predicted 30 percent decline in their worldwide population over the next 35 to 50 years. The principal cause of this decline is stated to be climatic warming and its negative effects on the sea ice habitat.
2017 The US Fish and Wildlife Service releases a report concluding that human-driven global warming is the biggest threat to polar bears and that if action isn’t taken soon the Arctic bears could be in serious risk of extinction. “It cannot be overstated that the single most important action for the recovery of polar bears is to significantly reduce the present levels of global greenhouse gas emissions.”
2010 Science: Fake polar bear picture chosen to illustrate a letter to Science about scientific integrity on climate change.
11. Glacier predictions
2007 IPCC AR4 says there is a very high likelihood that Himalayan glaciers will disappear by the year 2035 and perhaps sooner if the Earth keeps warming at the current rate.
IPCC officials recanted the prediction in 2010 after it was revealed the source was not peer-reviewed. Previously they had criticized the Indian scientist that questioned the prediction and ignored an IPCC author than in 2006 warned the prediction was wrong.
12. Sea level predictions
1981 James Hansen, NASA scientist, predicted a global warming of “almost unprecedented magnitude” in the next century that might even be sufficient to melt and dislodge the ice cover of West Antarctica, eventually leading to a worldwide rise of 15 to 20 feet in the sea level.
13. Sinking nations predictions
1989 Noel Brown, director of the New York office of the U.N. Environment Program (UNEP) says entire nations could be wiped off the face of the Earth by rising sea levels if the global warming trend is not reversed by the year 2000. As global warming melts polar icecaps, ocean levels will rise by up to three feet, enough to cover the Maldives and other flat island nations
