Does @AOC's prediction that we are all going to fry within 12 years because of CO2 emissions have any basis in empirical reality? (Or, for that matter, does her #GreenNewDeal utopia?)
Here is a chart from the NOAA National Centers For Environmental Information. It is a plot of the maximum temperatures for the hottest U.S. month - July - going back to 1895.
The trend line (blue line) plotted by NOAA reveals that maximum temperatures in July have been on a declining trend of -0.07°F per century since 1914 through July 2018.
And if the exact same NOAA plot was done for August maximum temperatures - the 2nd hottest month for U.S. summers - there is a declining trend of -0.26°F per century since 1928.
Unequivocally, the recent maximum temperatures over the most recent 5 years, during the two hottest months of summer, are not unprecedented.
Below is a table of the 10 hottest months since 1895, along with the respective global atmospheric CO2 level at the time. The lack of correlation between hottest years and CO2 is striking.
Clearly, all the human CO2 emissions produced during the modern era have not significantly changed the overall trend of maximum temperatures since the early 20th century.
Conclusion: The AOC climate change fearmongering, along with her fellow Green New Deal Democrats', is a narrative without any empirical evidence. The narrative that U.S. adults, children, and grandchildren will to survive in a 'living hell' that will destroy our society within the next 12 years is highly, highly unlikely. Per the evidence presented in the chart and table, we have survived warmer temperatures in the past, and will do so in the future because we've adapted and can now better cope with both higher and lower temperatures (thank the modern advances in technology, engineering, medicine, and food production and they will continue).
Note: Trend lines are not predictions. They provide a sense of direction from the past to a specific endpoint, but they provide absolutely no proof of what will take place in the future, especially with a global climate that is dominated by large natural oscillations and variations.
