  1. There is no objective observational evidence that we are living in a global climate crisis. The UN's IPCC AR6 WG1, chapter 12 "Climate Change Information for Regional Impact and for Risk Assessment", page 1856, section 12.5.2, table 12.12 confirms there is a lack of evidence or no signal that the following have changed: Air Pollution Weather (temperature inversions), Aridity, Avalanche (snow), Average precipitation, Average Wind Speed, Coastal Flood, Agricultural drought, Hydrological drought, Erosion of Coastlines, Fire Weather (hot and windy), Flooding From Heavy Rain (pluvial floods), Frost, Hail, Heavy Rain, Heavy Snowfall and Ice Storms, Landslides, Marine Heatwaves, Ocean Acidity, Radiation at the Earth’s Surface, River/Lake Floods, Sand and Dust Storms, Sea Level, Severe Wind Storms, Snow, Glacier, and Ice Sheets, Antarctic Sea Ice, Tropical Cyclones.

  2. @franckr6159  The only real change identified is an increase in heat globally but that has not resulted in any of the other calamitous changes foretold. No man made droughts, floods or hurricanes etc. How boring. Even table 12.12 confirms evidence is lacking or the signal is not present, leading to overall low confidence of an emerging signal both for the recent past and out to 2050 even under the most extreme climate modelling (RCP 8.5) of the following: Air Pollution Weather (temperature inversions), Aridity, Avalanche (snow), Average Wind Speed, Coastal Flood, Agricultural drought, Hydrological drought, Erosion of Coastlines, Fire Weather (hot and windy), Flooding From Heavy Rain (pluvial floods), Frost, Hail, Heavy Rain, Heavy Snowfall and Ice Storms, Landslides, Marine Heatwaves, Radiation at the Earth’s Surface, River/Lake Floods, Sand and Dust Storms, Severe Wind Storms, Glacier, and Ice Sheets, Tropical Cyclones. And that's under the extreme model 8.5, which is laughable. For more realistic trajectories there will be nothing to see.
