1/13》I remember when @Scientific American was a highly respected scientific periodical, rather than a political tabloid that reprinted disinformation like this, from other publications, written by nonscientists. https://twitter.com/ncdave4life/status/1508833038167330819…

2/13》Back when @Scientific American was trustworthy, you could read it to learn about what real scientific research was discovering about a wide variety of topics, including CO2. Here's an excellent Scientific American report — from a century ago: https://sealevel.info/ScientificAmerican_1920-11-27_CO2_fertilization.html…

3/13》The best evidence shows manmade climate change is modest & benign, and CO2 is beneficial. CO2 emissions & global warming have caused neither extinctions nor any other significant harm. In fact, they're saving thousands of human lives each year. Articles: https://www.heraldscotland.com/politics/19612103.bjorn-lomborg-blaming-deadly-floods-wildfires-climate-change-convenient-politicians/… https://unherd.com/thepost/bjorn-lomborg-how-global-warming-will-save-lives/… Paper: https://www.thelancet.com/journals/lanplh/article/PIIS2542-5196(21)00081-4/fulltext… Zhao et al (2021). Global, regional, and national burden of mortality associated with non-optimal ambient temperatures from 2000 to 2019: a three-stage modelling study. The Lancet 5(7), E415-425, July 2021. doi:10.1016/S2542-5196(21)00081-4

4/13》Have you noticed how little fur you have? Humans are a tropical species, and most of the Earth is much too cold. Studies show that even in tropical countries cold kills far more people than heat does. https://twitter.com/ncdave4life/status/1670083998087823362…

5/13》One of the reasons that global warming is saving lives is that it isn't very "global." It's disproportionately at chilly high latitudes, where it makes frigid winters slightly less harsh. The tropics are affected less, which is nice, because they're warm enough already. https://www.thelancet.com/journals/lancet/article/PIIS0140-6736(14)62114-0/fulltext…

6/13》Rising CO2 levels greatly improve global food security, by increasing crop yields, through "CO2 fertilization," and thanks to crops' improved water use efficiency and drought resilience. That's helping make famines rare for the first time in history. https://sealevel.info/learnmore.html?0=benefits#benefits…

7/13》Throughout human history, until the latter 20th century, famine was a Damoclean sword hanging over mankind: the "Third Horseman of the Apocalypse." If you're too young to remember catastrophic drought-triggered famines, count yourself blessed. https://sealevel.info/learnmore.html?0=madrasfamine#famine…

8/13》To put it in perspective: ● Covid-19 killed 0.1% of world population. ● 1918 flu killed about 2%. ● WWII killed 2.7%. ● The near-global drought and famine of 1876-78 killed about 3.7% of the world population. https://journals.ametsoc.org/view/journals/clim/31/23/jcli-d-18-0159.1.xml…

9/13》Natural ecosystems benefit from CO2 emissions, too. In fact, CO2 emissions are greening the Earth. https://www.nasa.gov/technology/carbon-dioxide-fertilization-greening-earth-study-finds/… https://sealevel.info/greening_earth_spatial_patterns_Myneni.html… This is NASA's video about it: https://www.youtube.com/watch?v=zOwHT8yS1XI…

10/13》Here are some more papers documenting the major beneficial effects of CO2 emissions. https://sealevel.info/negative_social_cost_of_carbon.html…

11/13》The CO2 Coalition has many great resources for learning the facts about CO2 and climate change: https://co2coalition.org/…

12/13》Many top scientists are members of the CO2 Coalition, where they volunteer their time for free, in support of sound science. https://twitter.com/GWrightstone/status/1655634353387446276…

13/13》To understand #ClimateChange (or any other politicized or contentious topic), you need balanced information. Sadly, you won't get it at Scientific American, anymore. But I'm here to help: https://twitter.com/ncdave4life/status/1215246375040049152…
