Dec. 3, 2018 – Scientists are to copy the effects of a massive volcanic eruption to block the Sun’s rays and combat global warming.
As part of a £2.3million ($3million) experiment partly-funded by Microsoft’s Bill Gates, a team from Harvard University will spray tiny chalk particles into the atmosphere 12 miles above the Earth to reflect some of the Sun’s rays back into space.
They hope this will have a similar effect to an erupting volcano releasing Sulphur dioxide. In 1991, Mount Pinatubo erupted in the Philippines, releasing 20million tons of Sulphur dioxide. That cooled the planet by 0.5C for 18 months (32.9 Fahrenheit).
Anchorage, Alaska has a subarctic climate due to its short, cool summers. Average daytime summer temperatures range from approximately 55 to 78 °F that would change it an average summer temperature of 25- to 48 degrees Fahrenheit. Nothing would grow!
Winters would be worst, average winter temperatures is 5 to 30 °F, but with this planed cooling it would be minus -30 to minus -5F. That’s without wind chill.
It is not unusual for South Dakota to have severe hot, dry spells in the summer with the temperature climbing above 100 °F (38 °C) several times a year. Winters are cold with January high temperatures averaging below freezing and low temperatures averaging below 10 °F (−12 °C) in most of the state.
So, winters in South Dakota would be harsh. Average temp would drop to Minus 15F. But there has been winter as cold as minus 50F. Can you live in an environment of a whopping 85 degrees below zero??????
In 2013 Tens of thousands of cattle perished in a freak snowstorm during the first weekend in October in Wyoming, Montana and South Dakota
Remember the movie “Day After Tomorrow.
New York. Low temperatures that drop below freezing are common in New York throughout winter. As well, November and April usually get the occasional night of frosty weather. New York on average has three nights a year when the thermometer sinks to 10 °F or lower. Just January and February normally have temperatures this cold. But what will people thing of an average winter temperature of minus -20F!
The goal is to reduce the worst effects of climate change in the hope that this could save coral reefs and polar ice sheets.
The team hopes to launch a steerable balloon over the southwest United States before next July. It will release jets of calcium carbonate: chalk dust. Scientists will measure how this affects the Sun’s light.
Opponents say spraying particles in such a way might damage the ozone layer and disrupt rainfall patterns, snow, which could cause drought in some areas, and flooding in others according to The Times.
Also, areas already cold could become too cold to live.
And they say such geo-engineering diverts attention from cutting greenhouse gas emissions.
They never mention the effects upon heath either, breathing in that chalk dust.
