Globe is warming at 0.2°C per decade.


Seems less according to REMSS and UAH. Wink

Jovial Monk wrote on Aug 17th, 2021 at 11:22am:
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

Continued ..

14. Food shortage predictions

1994 A study, by Columbia and Oxford Universities researchers, predicted that under CO2 conditions assumed to occur by 2060, food production was expected to decline in developing countries (up to -50% in Pakistan). Even a high level of farm-level adaptation in the agricultural section could not prevent the negative effects.

2008 Stanford researchers predicted a 95% chance that several staple food crops in South Asia and Southern Africa will suffer crop failures and produce food shortages by 2030, due to 1°C warming from the 1980-2000 average.

15. Climate refugee predictions

2005 Janos Bogardi, director of the Institute for Environment and Human Security at the United Nations University in Bonn and the United Nations Environment Program (UNEP) warned that there could be up to 50 million environmental refugees by the end of the decade.

2008 UN Deputy secretary-general Srgjan Kerim, tells the UN General Assembly, that it had been estimated that there would be between 50 million and 200 million environmental migrants by 2010.

2011 Cristina Tirado, from the Institute of the Environment and Sustainability at UCLA, says 50 million “environmental refugees” will flood into the global north by 2020, fleeing food shortages sparked by climate change.

16. Climate change casualty predictions

1987 Dr. John Holdren, director of the Office of Science and Technology Policy for the Obama administration then a professor at U.C. Berkeley was cited by Paul Ehrlich: “As University of California physicist John Holdren has said, it is possible that carbon dioxide climate-induced famines could kill as many as a billion people before the year 2020.”

1989 Noel Brown, director of the New York office of the U.N. Environment Program (UNEP) says that within the next 10 years, given the present loads that the atmosphere must bear, we have an opportunity to start the stabilizing process.

2006 NASA scientist James Hansen says the world has a 10-year window of opportunity to take decisive action on global warming and avert catastrophe

2007 U.N. Scientists say only eight years left to avoid worst effects .

B. Failure to predict

1. A greener planet

1992 The CO2 fertilization effect was well known, and experiments since at least 1988 showed that farm yields increased significantly. This was an easy prediction to make, yet it was ignored.

2. Increase in forest biomass

2006: For four of the past five decades global forest dynamics were thought to be primarily driven by deforestation. It was only in the last decade when it was noticed that a great majority of reports were contradicting that assumption. “Of the 49 papers reporting forest production levels we reviewed, 37 showed a positive growth trend.” The authors also write “climatic changes seemed to have a generally positive impact on forest productivity” when sufficient water is available.

3. Carbon sinks increases

1992: In the late 80’s a “missing sink” was discovered in the carbon budget accounting, and was discussed through the 90’s. The possibility that Earth’s oceans and terrestrial ecosystems could respond to the increase in CO2 by absorbing more CO2 had not occurred to climate scientists, and when it occurred to them they mistakenly thought that deforestation would be a higher factor.

The predictions are linked to their source.

Plenty of scientists there. Wink

Bushfires (wildfires elsewhere) are also growing in intensity—and dumping CO2 into the atmosphere.

While fuel reduction burns are done it gets hot earlier in the spring and summer so it gets harder and harder to manage fuel reduction burns safely.

Some alternative to fuel reduction burns is badly needed. AGW is not stopping as I have made clear in this thread.

The latest IPCC Report states we will reach 1.5°C above preindustrial by 2020.

Pretty much correct: we are 1.1°C above preindustrial now so two decades of 0.2°C warming and we are at 1.5°C.

Possibly the West Antarctic ice sheet is about to slide into the sea. It is heading that way. That will be “fun.” It will happen tho, unless emissions are stabilised and reduced.

At what temperature pet? The Antarctic is showing no sign of warming.

"Low Antarctic continental climate sensitivity due to high ice sheet orography"

"The Antarctic continent has not warmed in the last seven decades, despite a monotonic increase in the atmospheric concentration of greenhouse gases. In this paper, we investigate whether the high orography of the Antarctic ice sheet (AIS) has helped delay warming over the continent."

https://www.nature.com/articles/s41612-020-00143-w

Now we know CO2 is a well mixed gas and therefore the concentrations are the same as elsewhere. We also know Antarctica is a frozen desert with little precipitation. Therefore it seems clear that it is water and not CO2 that controls climate. Wink

That was the link requested petal. You said they are "growing in intensity" - that can only happen with more fuel. Why do you say something and then try and pretend it was something else entirely? Grin Grin Grin

Poor petal. Can't accept the obvious. Just as well you are not the mod here otherwise it would have disappeared.

No changes to the post. And there was a nine minute gap between mine and your posts so the change would have been noted. Why do you have this pathological need to lie? Grin Grin Grin Grin Grin
