Every Other Summer Will Shatter Heat Records Within a Decade

Every Other Summer Will Shatter Heat Records Within a Decade

SOURCE: Motherboard and Earth’s Future Open Access Journal DATE: November 1, 2017 SNIP: Think of the stickiest, record-hot summer you’ve ever experienced, whether you’re 30 or 60 years old. In 10 years or less, that miserable summer will happen every second year across most of the US and Canada, the Mediterranean, and much of Asia. By the 2030s, every second summer over almost all of the entire Northern hemisphere will be hotter than any record-setting hot summer of the past 40 years, the study found. By 2050, virtually every summer will be hotter than anything we’ve experienced to date. Record hot summers are now 70 times more likely than they were in the past 40 years over the entire Northern hemisphere, the peer-reviewed study...
Warm winters, scorching summers: New maps project impact of climate change

Warm winters, scorching summers: New maps project impact of climate change

SOURCE: National Post DATE: October 26, 2017 SNIP: Is this the end of the Great Canadian winter? A new report says that even if greenhouse gas emissions are reduced, all of Canada is projected to get warmer by the end of the century, while the number of 30 C plus days per year are predicted to “explode” under the current global warming trajectory. Overall, the globe is projected to warm by two to three degrees Celsius by 2051 to 2080, compared to 12 degrees or more for some places in the Canadian High Arctic, assuming the high-carbon future we’re trending towards, Smith said in an email. Toronto’s summers are projected to warm by four degrees Celsius by 2051 to 2080 in a high-carbon scenario; in comparison, its winters are projected to warm five degrees Celsius. Churchill summers will warm by 3.5 degrees Celsius; its winters by nine...
Australian cities to have 50C summer days by 2040, study says

Australian cities to have 50C summer days by 2040, study says

SOURCE: The Guardian DATE: October 3, 2017 SNIP: Even if the Paris agreement to limit the global temperature rise to below 2C is met, summer heatwaves in major Australian cities are likely to reach highs of 50C by 2040, a study published on Wednesday warns. The lead author of the study, the climate scientist Dr Sophie Lewis, said Sydney and Melbourne could expect unprecedented summer temperatures of 50C under two degrees of global warming. Governments needed to start thinking about how the public transport system would cope during peak hour in extreme temperatures, how emergency departments would respond to increased demand from elderly people and others vulnerable to heatstroke, and how energy requirements would be met during peak temperatures, she said. “I don’t think we have any plans in place that would be adequate to withstand days of 50 degrees and it is another urgent warning to our leaders and all levels of government that we need a strong plan to cut commissions and deal with climate...
In the U.S., year-to-date temperature and precipitation patterns not playing by their usual rules

In the U.S., year-to-date temperature and precipitation patterns not playing by their usual rules

SOURCE: Climate.gov DATE: August 31, 2017 SNIP: This year so far has been one of the warmest on record for the contiguous United States, with the January-July temperature ranking as the 2nd highest since records began in 1895. It has also been a wetter than average year (even before Hurricane Harvey), with the precipitation total for the first seven months of the year ranking as the seventh wettest in the 123-year record. So far, 2017 has been an extreme year. Temperatures and precipitation have been above average. The Climate Extremes Index ranked as the third highest on record. There have been nine billion dollar weather disasters. Hurricane Harvey broke the record-long streak of a major hurricane not hitting the United States. This year has also broken the mold in terms of how we think about the relationship between precipitation and temperature outcomes for the nation. Could this be a symptom of climate change or a potential new aspect of understanding climate and weather interactions? Well, that remains to be...
Death Valley just experienced the hottest month ever recorded in the U.S.

Death Valley just experienced the hottest month ever recorded in the U.S.

SOURCE: Washington Post DATE: Aug 3, 2017 SNIP: The average temperature in Death Valley last month was a stifling, suffocating 107.4 degrees. It was the hottest month ever recorded in the United States, and the second-hottest in the world — by just a fraction of a degree. The temperature didn’t fall below 89 degrees at any point in the month of July at Death Valley. On three nights, the “low” temperature was 102-103 degrees. The record-hot month in Death Valley adds to a growing group of locations to set all-time heat records this summer around the Northern...
