  1. Heat waves have not been increasing in intensity or frequency in the United States. 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. This year only 4 US states have achieved higher temperatures than 1936. 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. So far in 2023 (upto 1st August, 2023) the percentage of US Historical Climatology Network Stations reaching or exceeding 95°F (35°C) is at a record low (1895-2023) of 51%. The record high was 1931 at 93%. The trend has been consistently downwards since that point. The climate crisis was 90 years ago. You missed it.

  2. There has been a 10% decline in natural disasters since 2000 (CRED). Normalised disaster losses have decreased since 1990 and human mortality due to extreme weather has decreased by more than 95% since 1920.

  3. @JacktheSmack  You probably want to start in the 1960s. That's fine. I understand why. Can I recommend you pop over to the website "our world in data" and go to the page "Annual Heat Wave Index in the United States"? Don't worry, it sources its data from NOAA. Now you should see a red spikey thing - that's a graph. You'll enjoy moving the blue slider along the bottom. Notice that all the tallest spikes are in the 1930s. The very tallest (1936) is 1.3 on the severity index. The most recent readings are around 0.1, so that's a factor of 13. Imagine if you had a heatwave like that now. People like you would be screaming and dropping from apoplexy. How did your ancestors survive without air-con (or global warming!)? Anyway, there's only one, just one, place on this graph you can start and show an increasing trend. That's the 1960s (0.05). And that's why you've chosen it (or it was chosen for you). Now that is a mighty fine cherry. Another lesson to draw from this is that there is zero positive correlation between the concentration of CO2 in the atmosphere and heatwaves.

  4. There has been no clear change in annual precipitation over the Earth's landmasses between 1850-2000 (Wijngaarden, 2015). Drought appears to be decreasing globally (Watts et al, 2018) measured by SPI 1901-2017.

  5. @JacktheSmack  Not into evidence based reality then?

  6. This is nonsense. It was hotter in the recent and distant past. There is no satellite data before 1979, and there was no real network of temperature stations outside Europe and America before the 1950s, so "hottest ever" is not very long! It was much hotter in America in the 1930s. Heatwaves were more than 6 times worse with greater frequency and covering a larger area (Kunkel, 2022, EPA). Further back the Vikings grew barley on Greenland, which is impossible today. This is bull meant to scare people into giving up their prosperity. Satellite data shows the Earth is continuing to warm at around one-tenth of a degree Celsius per decade. If we didn't have thermometers we couldn't even notice it. The IPCC AR6 report, chapter 11 'Weather and Climate Extreme Events in a Changing Climate' summarises the fact that severe weather events cannot be detected as increasing, nor attributed to human caused climate change: Pages 1761 - 1765, Table 11.A.2 Synthesis table summarising assessments Heavy Precipitation: 24 out of 45 global regions low confidence in observed trend (12 medium confidence, so 50-50), 43 out 45 low confidence in human attribution. Agricultural Drought: 31 out of 45 global regions low confidence in observed trend (14 medium confidence, so 50-50. No high confidence assessment). 42 out 45 low confidence in human attribution (3 medium, no high confidence). Ecological Drought as above. Hydrological Drought: 38 out of 45 global regions low confidence in observed trend. 43 out 45 low confidence in human attribution (2 medium confidence, no high confidence). So the IPCC are saying we didn't cause droughts and we didn't make it rain. How surprising!

  7. There is no objective observational evidence that we are living in a global climate crisis. The UN's IPCC AR6, chapter 12 "Climate Change Information for Regional Impact and for Risk Assessment", 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, Tropical Cyclones. There is no objective observational evidence that we are living through a global climate crisis. None.

  8. No. June 2023 was a long way from being the hottest. It ranks only 5th, behind 1676, 1822, 1826 and 1846
