Climate Claim Fact Checks Updated

Joseph D’Aleo, CCM

Below are a series of fact checks of the 13 most common climate claims such as those made in the recently released Fourth National Climate Assessment Report. The authors of these reviews are all recognized experts in the relevant fields. For each claim, a summary of the relevant rebuttal is provided below along with a link to the full text of the rebuttal, which includes the names and the credentials of the authors of each rebuttal.

Climate Change Claim Fact Checks With updates through 04/18/21

Claims that the globe has experienced the warmest ever month or year are unsupported by data and are in reality politically driven fictions.

Heat Waves - have been decreasing since the 1930s in the U.S. and globally.

Hurricanes - the decade just ended as the second quietest for landfalling. hurricanes and landfalling major hurricanes in the U.S since the 1850s. 2020 saw a record 30 named storms and many Gulf impacts like the quiet solar periods in the late 1800s and this century, but the AC index ranked 13th highest. See 2020 Update showing similarities to late 1800s here and global contrasts here.

Tornadoes - the number of strong tornadoes has declined over the last half century. More active months occur when unseasonable cold spring patterns are present.

Droughts and Floods - there has no statistically significant trends

Wildfires - decreasing since the very active 1800s. The increase in damage in recent years is due to population growth in vulnerable areas and poor forest management. See Australia Wildfire story here.  See this analysis that shows how public lands are ablaze but private lands are not because they are properly managed here.

Snowfall - has been increasing in the fall and winter in the Northern Hemisphere and North America with many records being set.

Sea level - the rate of global sea level rise on average has fallen by 40% the last century. Where today, it is increasing - local factors such as land subsidence are to blame. See how sea level trends are being adjusted here.

Arctic, Antarctic and Greenland Ice - the polar ice varies with multidecadal cycles in ocean temperatures. Current levels are comparable to or above historical low levels. Arctic ice returned to higher levels with a very cold winter in 2019/20. Ice was highest level since 2013. See update here on the AMO, PDO ocean cycles, the Solar and Arctic temperatures.

Alaska July 2019 heat records/ winter 2019/20 cold - the hot July resulted from a warm North Pacific and reduced ice in the Bering Sea late winter due to strong storms. Record ice extent occurred with record cold in 2012. 2019/20 has been the third coldest winter in Fairbanks since the Great Pacific Climate Shift in the late 1970s.

Ocean Acidification” - when life is considered, ocean acidification (really slightly reduced alkalinity) is a non-problem, or even a benefit.

Carbon Pollution as a health hazard - carbon dioxide (CO2) is an odorless invisible trace gas that is plant food and it is essential to life on the planet. CO2 is not a pollutant.

Climate change is endangering food supply - the vitality of global vegetation in both managed and unmanaged ecosystems is better off now than it was a hundred years ago, 50 years ago, or even a mere two-to-three decades ago thanks in part to CO2.

There is a 97% consensus that climate change is man-made - a 97% consensus is a convenient fiction meant to bypass the scientific method and sway public opinion and drive societal changes and policies that support political agendas.

Thank you for your support. You have kept us going the last few years. No corporate donor or grants come to our aid on fear of the cancel culture. Support Icecap efforts with even small donations via a secure access to Paypal. All work is done pro bono. Be sure to check out the search engine for many stories on any topic. We have 9000 entries with 150 million page views. Our team is fact checking the alarmist claims now that 2020 has ended. I will update by April. We are publishing a paper also on the topic.

Going to be a wild ride the next few years. Politics and science pushed by globalists and the media are corrupted and young people are being misled by a failing education system and this causes family discord. So many honest scientists are being attacked or punished and legions have been silenced. The battle started nearly 25 years ago when 31,487 American scientists signed this petition, including 9,029 with PhDs. The battle will continue, must continue.
