TORRID TEMPS IN TUNDRA: Canada’s Central Yukon Territory is the warmest its been in 13,600 years, researchers at the University of Toronto Mississauga have concluded in a new study.
Paleoclimatologists, who use radiocabon dating preserved in permafrost, along with other methods, were able to reconstruct summer temperatures over the last 13,600 years. They found that temperatures are nearly 2 degrees Celsius warmer than any previous summers during the Holocene period.
“We’re seeing the evidence right now that climate warming is destabilizing permafrost in northern Canada and releasing greenhouse gases,” said lead author Trevor Porter. “This is potentially the new normal and, if it accelerates in the near future, it threatens to further amplify global climate change.”
In March, the temperature soared to an unprecedented 71 degrees in Yohin Lake in Canada’s Northwest Territories and 76 in Tofino, British Columbia. Temperatures in the Arctic have been increasing at more than twice the rate of increases in the continental U.S., experts say.
MORE RECORD WARMTH FOR FLORIDA: Overnight lows could run up to 10 degrees above average this week as an unusually strong ridge of high pressure builds over the state, forecasters said Sunday.
For perspective, the normal low this time of the year in Miami is 68; the normal high is 83.
After a slight cool-down statewide on Tuesday and Wednesday as the cold front clears the peninsula, highs will pop back to “significantly” above normal by mid-week, the National Weather Service said.
A round of record warm lows occurred on Saturday. Here’s the rundown:
- Fort Pierce tied a record warm low with 74 degrees. The city hasn’t seen an April 13 low that warm in 71 years — the record was originally set in 1948.
- Marathon set a new record warm low with a balmy 81 — easily beating the old record of 79 set in 2015.
- The low in Fort Lauderdale was 77, which tied a record warm low set in 2015.
- Daytona Beach tied a record warm low with 72, a mark originally set in 1991.
- Melbourne tied a record warm low with 73, matching the record set in 2015.
- The low was also 73 in Vero Beach, tying a record set in 1991.
- Sanford broke a record warm low with 72. The old record was 71 set in 2001.
- Jacksonville’s low of 71 beat the previous record warm minimum of 69 degrees set in 2015.
- Gainesville’s low of 71 smashed the old record, set in 1974, by 3 degrees.
