"Take unusually warm Atlantic ocean surface temperatures (temperatures are in the 70s off the coast of Virginia), add a cold Arctic outbreak (something we’ll continue to get even as global warming proceeds), mix them together and you get huge amounts of energy and moisture, and monster snowfalls, like we’re about to see here," said Michael Mann, a climate researcher who directs Penn State University's earth systems science center. Mann said the ocean temperature anomalies of 5 to 6 degrees Fahrenheit above average would yield more than a 20% increase of the moisture content of the air overlying that layer of ocean waters. That air, in turn, "is getting entrained into the system to produce the heavy snowfalls," he said in an email to Mashable. Mann said it isn't clear how big of a role climate change might be playing, though, compared to other factors.
But...Ryan Maue, a meteorologist with the private weather firm WeatherBell Analytics, said on Twitter that the process of forming a rapidly intensifying coastal storm involves much more than just higher-than-average sea-surface temperatures.
The ‘Danmask-19 trial’ was conducted in the spring with over 6,000 participants, when the public were not being told to wear masks but other public health measures were in place. Unlike other studies looking at masks, the Danmask study was a randomised controlled trial – making it the highest quality scientific evidence. ...
In the end, there was no statistically significant difference between those who wore masks and those who did not when it came to being infected by Covid-19. 1.8 per cent of those wearing masks caught Covid, compared to 2.1 per cent of the control group. As a result, it seems that any effect masks have on preventing the spread of the disease in the community is small. ...
The results of the Danmask-19 trial mirror other reviews into influenza-like illnesses. Nine other trials looking at the efficacy of masks (two looking at healthcare workers and seven at community transmission) have found that masks make little or no difference to whether you get influenza or not.
"Fat is converted to carbon dioxide and water. You exhale the carbon dioxide and the water mixes into your circulation until it’s lost as urine or sweat." "If you lose 10kg of fat, precisely 8.4kg comes out through your lungs and the remaining 1.6kg turns into water. In other words, nearly all the weight we lose is exhaled."
"To lose 100 grams of fat, you have to exhale 280 grams of carbon dioxide on top of what you’ll produce by vaporizing all your food, no matter what it is."
