Scientists believe they have identified the world's cleanest air, free from particles caused by human activity, located over the Southern Ocean, which surrounds Antarctica.

In a first-of-its-kind study of the bioaerosol composition of the Southern Ocean, researchers from Colorado State University identified an atmospheric region which remains unchanged by human activity.

Researchers found that the boundary layer air, which feeds the lower clouds over the Southern Ocean, was free from aerosol particles produced by human activity Researchers decided to study what was in the air, and where it came from, using bacteria in the air as a diagnostic tool to infer the properties of the lower atmosphere.

Scientists sampled the air in the marine boundary level -- the part of the atmosphere that has direct contact with the ocean -- while aboard a research boat traveling south to the Antarctic ice edge from Tasmania, Australia. Scientists then examined the composition of airborne microbes, which are found in the atmosphere and often dispersed thousands of kilometers by the wind.

Climate change behind increases in extreme rain danger, scientists sayResearch from Environment Canada shows that climate change is behind more extreme rainfalls in Canada and suggests the problem is likely to get worse So every time it rains and snow and there is sunny its climate change wow the best way to brain wash 12-16 years old. Climate models are just as accurate as the covid models. Scientists say is the new way to say “we are spouting shit so you should pay attention”. No credibility when I see this.

Man found dead at home on Salt Spring, woman dies later; police say no public riskMan found dead at home on Salt Spring, woman dies later wtf? maybe don't spend half the article praising a guy who murdered his wife Please pull this article immediately - this man murdered his wife. Her family and friends do not deserve to have to read accolades in the press about his life, nor thinly veiled excuses about how the stress of the pandemic may have caused this. I am enraged after reading this hagiography of a man who murdered his partner, . It is offensive and irresponsible. You should pull the entire piece and either re-write completely or let more responsible publishers cover the story.

The sixth mass extinction is happening faster than expected. Scientists say it's our fault.The sixth mass extinction is not a worry for the future. It's happening now, much faster than previously expected, and it's entirely our fault, according to a study published Monday. That’s because we’re a plague on this planet....an insidious virus thats multiplying and getting worse by the minute. so stop fucking talking about it and do something. the average citizens dont have the resources to help in a meaningful way. this needs to start with the top, but we know all they care about is how much money they can die with A tax would probably help.
