It is Extremely Unlikely that SARS-CoV-2, the Virus that Causes COVID-19, Came from a Lab

The COVID-19 pandemic continues due to SARS-CoV-2, the virus that causes the disease COVID-19. Unfortunately and predictably, baseless claims spread on the origin of SARS-CoV-2, just as conspiracy theories also spread on the origin of the AIDS pandemic caused by the virus HIV. These claims center on the conspiracist idea that SARS-CoV-2 came from a lab, instead of naturally evolving and spreading completely outside of a lab. The sources below undermine this idea in its various forms.

1.  The Myth and Its Flaws



In 1997 [677] or 1998, global warming paused / underwent a hiatus [4; 5; 7; 8 - 10; 13; 54; 55; 57; 670; 680], and will likely continue to do so until the 2030s [4; 9; 14; 57; 1182, with 1180]. Moreover, climate shifted in 2001/2002 [2; 3], supporting a prediction of post-2002 global cooling [3]. This rebuts the United Nations Intergovernmental Panel on Climate Change's (IPCC's) [7; 10; 54; 55; 98] use of climate models [1140] to predict global warming, since the IPCC predicted a warming trend of about ~0.2°C/decade [7; 18; 97; 98; 211; 212, as per 211, 213, and 214; 215; 216, page 133; 217, figure 3; 218, pages 14 - 15; 219; 220, section 3.4; 221 - 223; 224, page 84; 225, page 16; 226; 227, figure 24 on page 456; 228]. Consistent with this lack of warming, as of the beginning of 2019, 2018 would not be one of the top five warmest years in the thermometer record [32].
