Here they are again. I'd hate to have to strain your brain looking for them
It is an old argument that AGW is not falsifiable. Let me put up a few things that might undo it:
1) Show that CO2 does not act as a greenhouse gas
2) Show that CO2 levels are not increasing
3) Show that the increased CO2 in the atmosphere is not of human origin
4) Repeat 1-3 concerning methane
5) Show that humans are not responsible for deforestation
6) Show that deforestation has had no effect on CO2 levels in the atmosphere
7) Show that the planet is not warming
8) Show that something other than the greenhouse effect is responsible for the observed warming
9) Show that the planet will soon cease to warm and begin cooling off
10) Show that all the world's climate scientists are involved in a massive conspiracy to falsify all the evidence supporting AGW
11) Show that warming threatens no harm whatsoever
12) Show that warming will be a net benefit to humankind.
Let me know if you need more.
Cute list...completely stupid but cute that you believe it amounts to something...you want to know what falsifies a hypothesis? Predictive failures falsify a hypothesis...
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).” See, page xi.
Reality check: Since 1990 the warming rate has been from 0.12 to 0.19°C per decade depending on the database used, outside the uncertainty range of 1990.
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.” See, page xi.
Reality check: From 1990 to 2017 (first 8 months) the increase in temperatures has been 0.31 to 0.49°C depending on the database used.
2001 IPCC TAR (AR3) predicts that milder winter temperatures will decrease heavy snowstorms
2014 Dr. John Holdren, director of the Office of Science and Technology Policy for the Obama administration said: “a growing body of evidence suggests that the kind of extreme cold being experienced by much of the United States as we speak is a pattern we can expect to see with increasing frequency, as global warming continues.
Reality check: By predicting both milder winters and colder winters the probability of getting it right increases. Now, to cover all possibilities they simply need to predict no change in winters.
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.”
2001 IPCC TAR (AR3) predicts that milder winter temperatures will decrease heavy snowstorms.
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.
Reality check: 2014 had the snowiest Scottish mountains in 69 years. One ski resort’s problem was having some of the lifts buried in snow. Northern Hemisphere snow area shows remarkable little change since 1967. The 2012-2013 winter was the fourth largest winter snow cover extent on record for the Northern Hemisphere.
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%.
Reality check: Only six years later, IPPC acknowledges that confidence is low for a global-scale observed trend in drought or dryness (lack of rainfall) since the middle of the 20th century, and that AR4 conclusions regarding global increasing trends in drought since the 1970s were probably overstated.
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.
Reality check: After 40 years of global warming no increase in hurricanes has been detected. NOAA U.S. Landfalling Tropical System index shows no increase, and in fact, a very unusual 11-year drought in strong hurricane US landfalls took place from 2005-2016.
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.
2012 Steve Running, a wildfire expert, ecologist and forestry professor at the University of Montana says the fires burning throughout the U.S. offer a window into what we can expect in the future as the climate heats up.
Reality check: The global area of land burned each year declined by 24 percent between 1998 and 2015, according to analysis of satellite data by NASA scientists and their colleagues. Scientists now believe the decrease in forest fires is increasing 7% the amount of CO2 stored by plants.
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.
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
Reality check: Doing one thing and its opposite simultaneously has always been possible for climate change. However, the International Earth Rotation and Reference Systems Service (IERS) informs us that the Earth slowed down from the start of measurements in 1962 to 1972, and sped up between 1972 and 2005. Since 2006 it is slowing down again. It shows the same inconsistency as global warming.
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
2010 Mark Serreze, director of the NSIDC predicts the Arctic will be ice free in the summer by 2030
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
Reality check: No decrease in September Arctic sea ice extent has been observed since 2007,
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.
Reality check: Average September Arctic sea ice extent for the 1996-2005 period was 6.46 million km2. It declined by 26% to 4.77 million km2 for the 2007-2016 period. Despite the sea ice decline the polar bear population increased from a 20,000-25,000 estimate in 2005 to a 22,000-31,000 estimate in 2015.
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.
PCC 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.
981 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
Reality check: Since 1993 (24 years) we have totaled 72 mm (3 inches) of sea level rise instead of the 4 feet that corresponds to one-fourth of a century. The alarming prediction is more than 94% wrong, so far.
And it goes on and on...predictions of sinking nations...predictions of global food shortages....predictions of climate refugees...time running out predictions...
Then there are the things that climate science failed to predict like a greener planet.....an increase in forest biomass...increases in CO2 sinks....the slow down in warming....and on and on...
predictive failure after predictive failure and every one of them is falsification of the AGW hypothesis...
