Alarmist Claim Rebuttal Overview[1]

Below are a series of rebuttals of the 11 most common climate alarmists’ claims such as those made in the recently released Fourth National Climate Assessment Report.[2] The authors of these rebuttals are all recognized experts in the relevant

For each alarmist 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.

  • Heat Waves – have been decreasing since the 1930s in the U.S. and globally
  • Hurricanes – hurricane activity is flat to down since 1900, landfalls in the US are declining
  • Tornadoes – the number of strong tornadoes have declined over the last half century
  • Droughts and Floods – no statistically significant trends
  • Wildfires – decreasing since 1800s. The increase in damage in recent years is due to population growth in vulnerable areas and poor forest management
  • Snowfall – 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 it is increasing – local factors such as land subsidence are to blame.
  • 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
  • Alaska July 2019 heat records – this resulted from a warm North Pacific and reduced ice in the Bering Sea late winter due to strong storms. The opposite occurred with record cold in 2012.
  • Ocean Acidification – when life is considered, ocean acidification is often found to be 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. It 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.
Claim: Heat Waves are increasing at an alarming rate and heat kills.
