The Paris Climate Agreement of 2016, which saw 195 nations come together in the shared goal of ameliorating climate change, set forth an ambitious goal of limiting global temperature rise to less than 2 degrees Celsius. Since then, many have wondered, is that even scientifically possible? Unfortunately, the odds aren’t looking good.

Boston, MA – If CO2 levels continue to rise as projected, the populations of 18 countries may lose more than 5% of their dietary protein by 2050 due to a decline in the nutritional value of rice, wheat, and other staple crops, according to new findings from Harvard T.H. Chan School of Public Health. Researchers estimate that roughly an additional 150 million people may be placed at risk of protein deficiency because of elevated levels of CO2 in the atmosphere. This is the first study to quantify this risk.

A Canadian-led investigation involving York researchers has opened a new chapter in antimatter research.

In a study published in Nature today (Aug. 3), the ALPHA Collaboration – a group of international physicists including physics Professor Scott Menary in the Faculty of Science at York University – reported the first detailed observation of spectral lines from an antimatter atom.

With many Americans choosing to eat less meat in recent years, often to help reduce the environmental effect of meat production, UCLA geography professor Gregory Okin began to wonder how much feeding pets contributes to issues like climate change.

University of Lethbridge biogeography professor Dr. Dan Johnson and his team have been monitoring Prairie potato fields for the past few years, looking for evidence of the potato psyllid insect and a bacterium it can carry that can lead to zebra chip disease in potato crops.

“We found hundreds of potato psyllids last year, but we have found under 10 so far this year and none have the bacteria that cause zebra chip,” says Johnson, who coordinates the Canadian Potato Psyllid and Zebra Chip Monitoring Network.
