  1. From the NOAA GFDL website 'Global Warming and Hurricanes, An Overview of Current Research' (dated Feb. 9, 2023). And I quote "We conclude that the historical Atlantic hurricane data at this stage do not provide compelling evidence for a substantial greenhouse warming-induced century-scale increase in: frequency of tropical storms, hurricanes, or major hurricanes, or in the proportion of hurricanes that become major hurricanes."

  2. windspeed overland throughout the Northern Hemisphere has been dropping in recent decades. Also the number of intense storms (below 960 mbars) in the Northern Atlantic has fallen sharply since 1990 (Tilinina et al, 2021).

  3. @Junieper  Didn't you just do a "fun cherry pick" starting in 1979, a year of record high ice extent? But chose to ignore the longer term data in my comment "The AARI data shows the sea ice concentration anomaly was lower in 1952 (-5%) than 2005 (-3%). The anomaly increased in the 50s, 60s and 70s. In the 80s, 90s and early 2000s it decreased. Since 2007 the trend has been flat. " You have to cherry pick 1979.

  4. Globally the ACE index (accumulated cyclone energy) 1980-2021 shows no increasing trend. Global Hurricane Landfalls 1970-2021 (updated from Weinkle et al, 2012) shows no trend.

  5. Satellite data since 1980 shows a slight downward global trend for total hurricaine numbers with 2021 being a record low year.

  6. Global temperatures maxed out in 2016 and have been lower ever since (UAH v6 global satellite data). 500 billion tonnes of emissions in that time (14% of man-made CO2) and no warming. There is no climate crisis.

  7. NOAA data 1851-2021 shows no trend in number of hurricaine landfalls with the record high being 1886.

  8. @Junieper  As regards the melting of Arctic Ice, the doomsters records nearly always seem to start in 1979. Strange that, considering it was a year of record extent for Arctic Ice. Didn't someone predict in 2007 Arctic ice free by 2010, or 2015, or 2013, or in 5 years? Or was it in 2008 the Arctic ice sheet would melt away. Also predicted in 2008 North Pole ice free in ... 2008 ... or in 10 years. 2009 prediction: Arctic ice free in 2014. 2012 prediction: snow will be gone by 2020. And 2013 star prediction: Methane catastrophe in 2 years because of ice free Arctic. 2018 prediction: zero chance of permanent ice in Arctic by 2022. The Arctic Ice is still there, and it's stopped shrinking. If you consider global sea ice cover, it was basically flat from 1981 to 2008, rose until 2010, stayed level until 2015, dropped until 2018, and then rebounded almost all the way back to the 1990-2000 average. And now it's gone down again. So what? Nobody predicted theses changes, nor can they explain them. The changes have no relationship to the concentration of CO2 in the atmosphere. The climate crisis/emergency/apocalypse is make-believe.

  10. @Junieper  Are you choosing to ignore data from before 1979? How convenient, as it shows growth in the ice for the decades prior. Do you accept that the Arctic Ice may have grown in the 50s 60s and 70s? And what happens if you start plotting after 1989?

  11.  @Junieper  What about Polyakov, Vinje, HadCRUT4 Arctic, and KMNI? They make reference to the situation before 1979. Do you accept them?

  12. @Junieper  Thank you for the reply. Where are you getting your 1950s onwards ice data?

  13. Lies and propaganda. Burn acreage was much, much, higher in the US during the 1920's, 30's and 40's. It peaked in 1930 at well over 50,000,000 acres. The trend is downwards (1926-2020 NIFC US) eventhough CO2 has increased exponentially. For 2000 onwards the average burn acreage is much less than 10,000,000 acres. The number of fires has also declined. Remember CO2 was increasing all the time. For the whole of Canada the largest burn acreage was 1989, and there is no trend for the period 1980-2021. Over that same period the trend for number of fires was slightly downwards (CNFDB). Note that 2020 had the lowest recorded burn acreage and number of fires. Data for Siberia seems harder to come by. However, for the period 1997-2016, the trend was highly variable (by a factor of 4) but the trend for the annual burn acreage was downwards (Global Fire Data). For the Amazon (2003-2019), 2010 was the record year for fire emissions with all subsequent years lower by at least ½. Furthermore, with regard to the IPCC, they have not detected or attributed the number of fires or the burn acreage to man-made climate change. Also IPCC only has medium confidence ( that's a 50-50) that weather conditions that promote wildfires (fire weather) have become more probable in southern Europe, northern Eurasia, the USA, and Australia over the last century. Note that annual Global Wildfire Carbon Emissions have been declining dramatically since 2003, with 2022 being the lowest on record (Copernicus). There is no climate crisis.

  14. NASA satellite data (1993-present) for Global Mean Sea Level shows a linear rise of 3.3mm per year. That's the same as two stacked penny coins. All linear. No acceleration, so no relationship to the exponential increase in CO2 in the atmosphere. It's going to be decades before even your big toe is submerged.
