  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. Heat waves have not been increasing in intensity or frequency in the United States, which has by far the best meteorological data both spatially and temporally. Data from NOAA's Climate Reference Network shows no sustained increase in daily high temperatures in the United States since 2005 when that network began. In recent decades in the United States, heat waves have been far less severe than they were in the 1930s. At that time Heatwaves were more than 6 times worse with greater frequency and covering a larger area than the last decade (EPA). The most severe heatwave year was 1936, and was about 13 times worse than current. Many states in 1936 achieved temperatures 15° hotter than the present. The all-time high temperature records set in most states occurred in the first half of the twentieth century. The percentage of US Historical Climatology Network Stations reaching or exceeding 95°F (35°C) was at a record low (1895-2023) of 51% in 2023. The record high was 1931 at 93%. The trend has been consistently downwards since the thirties. The climate crisis was 90 years ago. You missed it.

  3. America has by far the best instrumental data, and it shows overall the South East cooled in the last 120 years. Though that sentence doesn't do justice to the climate's variability. Data from NOAA (2021) shows uneven warming in the twentieth century focused on the South East through until it peaks in the 1930s. Where it should be noted the highest average maxima temperature records remain to this day. Some areas of the West US showed negligible warming. There then followed a general continent-wide cooling into the 1970s. Then the West began to warm, but the South East continued to cool, so that by the end of the century some SE areas were cooler than they had been a century before. This pattern of uneven warming continues up to the present day.

  4. If you're worried about deaths due to climate, cold temperature events are the big killer, not heat. It is estimated that 5.1 million people annually die in association with non-optimal temperatures. 4.6 million are linked to the cold, so over 90% (Zhao et al, 2021). And it is worst in the warmer parts of the world. 98% of temperature related deaths in SubSaharan Africa are due to the cold. Temperature events may be linked to upto 10% of human deaths annually. In a warming world there will be less death. There are over 5 million excess deaths per annum globally due to abnormal temperatures from the 2000-2019 study led Prof. Guo of Monash University. It found that over 90% of excess deaths were caused by excess COLD rather than excess heat. So, in a world with increasingly mild temperatures, there will be less excess death. Lives will be saved. Warming is good not bad. A 2022 Lancet study reported 791 heat-related excess deaths and 60,753 cold-related excess deaths in England and Wales each year during the years spanning 2000-2019. That’s an excess death ratio of about 85 to 1 for cold vs. hot temperatures. Due to warmer urban temperatures, the number of premature cold-related excess deaths avoided averaged 447 per year from 1976-2019 in the city of London alone (Hajat et, 2024).
