Australia s bushfires circle Sydney as temperatures soar Reuters
samedi, 21 décembre 2019 à 13:54 - Six fires in the state were rated at emergency level, including two around Sydney.
SYDNEY (Reuters) - Catastrophic conditions fueled massive bushfires across Australia s New South Wales state on Saturday, with two blazes around Sydney burning at emergency level, while in South Australia one person was found dead in a fire zone.
Some major roads heading to the south and west from Sydney were closed for part of the day and authorities asked people to delay travel at the start of the Christmas holiday period, warning of the unpredictability of the fires due to high winds and temperatures above 40°C (104F).
Melting permafrost splitting trees, threatening highways in Yukon

mardi, 28 juillet 2020 à 06:30 - Many communities in Northern Canada are beginning to brace for an increased threat as temperatures warm and permafrost continues to melt.
The research has told us that Canada’s North is warming faster than the rest of the country. A 2019 study entitled Canada’s Changing Climate Report says that Northern communities, like the Yukon, are warming two times faster than the rest of the world, with territories seeing a 2.3°C increase.
This change in temperatures has had several impacts in the Yukon, including changes in amounts of rain and snow, more extreme weather events, melting glaciers and sea ice, and thawing permafrost. On a recent trip to the Yukon, The Weather Network had a chance to experience the later first hand.
NASA astronauts return to Earth in SpaceX capsule after historic mission Reuters
dimanche, 2 août 2020 à 19:40 - The landmark mission, launched from NASA s Kennedy Space Center on May 31, marked the first time the U.S. space agency launched humans from American soil since its shuttle program retired in 2011.
(Reuters) - U.S. astronauts Bob Behnken and Doug Hurley, who flew to the International Space Station in SpaceX s new Crew Dragon, splashed down in the capsule in the Gulf of Mexico on Sunday after a two-month voyage that was NASA s first crewed mission from home soil in nine years.
Behnken and Hurley undocked from the station on Saturday and returned home to land in calm waters off Florida s Pensacola coast on schedule at 2:48 p.m. ET following a 21-hour overnight journey aboard Crew Dragon Endeavor.
How cold is too cold to exercise outside?

As life in lockdown continues, Canadians have had to get creative with their workout regime and for many, it meant heading outside.
However, as the coldest months of the year are now underway, it s important to know the potential risks involved in taking your workout outdoors during winter.
“Through my research, the threshold of -15 C is something individuals and habitually active Canadians should pay attention to,” says Michael Kennedy, Associate Professor at the University of Alberta who specializes in Kinesiology and Recreation.
The reason for this is respiratory distress. Kennedy and his team conducted a study that tested athletes running on a treadmill in the following temperatures: 0, -5, -10, -15 and -20 C (40 per cent humidity).
2020 is on track to be Earth’s warmest year on record

jeudi, 23 avril 2020 à 13:15 - Despite the widespread drop in greenhouse gas emissions during the COVID-19 pandemic, NOAA reports that global temperatures will be record-breaking in 2020.
While the COVID-19 lockdowns have caused dramatic declines in greenhouse gas emissions, abnormally warm global temperatures are telling us that the climate is still heading into unprecedented territory.
The National Oceanic and Atmospheric Administration (NOAA) has reported that there is a 75 per cent chance 2020 will be the warmest year on Earth since record-keeping began in 1880. Global temperatures are expected to be warmer than those in 2016, which was declared the warmest year on record at the time. The unusually strong El Niño event of 2015-2016 contributed to 2016’s record-breaking warmth. There are currently no indications that we will see an El Niño event this year, however, which makes NOAA’s projection
