Trees are Dying of Thirst in the Western Drought – Here’s What’s Going on Inside Their Veins
June 29, 2021

https://theconversation.com/trees-are-d ... ins-162385

Introduction:
(The Conversation) Like humans, trees need water to survive on hot, dry days, and they can survive for only short times under extreme heat and dry conditions.

During prolonged droughts and extreme heat waves like the Western U.S. is experiencing, even native trees that are accustomed to the local climate can start to die.

Central and northern Arizona have been witnessing this in recent months. A long-running drought and resulting water stress have contributed to the die-off of as many as 30% of the junipers there, according to the U.S. Forest Service. In California, over 129 million trees died as a consequence of a severe drought in the last decade, leaving highly flammable dry wood that can fuel future wildfires.

Firefighters are now closely watching these and other areas with dead or dying trees as another extremely dry year heightens the fire risk.

As someone living in the Pacific Northwest, it's been absolutely brutal the past few days. Daytime temperatures broke records, reaching into the mid-high 40s multiple days in a row. There was no reprieve at night, with high humidity keeping temperatures elevated into the high 20s. It seems like the heat dome has started breaking down, as temperatures finally failed to break 40 today. It's the first time I can even think in days, it's been so hot. The hottest I ever remember.

According to climate science, we can expect events such as these to become more common than once a century. I think if this becomes a typical summer phenomenon, living in underground cities would not be such a bad idea. AC places a huge demand on the power grid, and it may end up being a better solution to simply live in naturally cool places.

Multnomah County Medical Examiner finds 45 deaths related to historic heat wave
Status message

June 30, 2021
https://www.multco.us/multnomah-county/ ... qKIq_UQdgA
The Multnomah County Medical Examiner Program has identified 45 deaths related to excessive heat since Friday, June 25. The preliminary cause of death is hyperthermia. Hyperthermia is an abnormally high body temperature caused by a failure of the body to deal with heat coming from the environment.

The people who died ranged in age from 44 to 97; and include 17 women and 27 men. (records regarding gender were not complete). Many had underlying health conditions. Many of those who died were found alone, without air conditioning or a fan.
For comparison, for all of Oregon between 2017 and 2019, there were only 12 deaths from hyperthermia.

“This was a true health crisis that has underscored how deadly an extreme heat wave can be, especially to otherwise vulnerable people,’’ said Multnomah County Health Officer Dr. Jennifer Vines. “I know many county residents were looking out for each other and am deeply saddened by this initial death toll. As our summers continue to get warmer, I suspect we will face this kind of event again.’’

The deaths occurred as County officials recorded the highest-ever number of 911 calls for medical emergencies and a dramatic spike in heat-related emergency department and urgent care care visits.

Between Friday, June 25, when the National Weather Service excessive heat warning went into effect, and Monday, June 28, there were 131 emergency department and urgent care clinic visits for heat illness in Multnomah County. Normally we would see one.

US heatwave: NASA satellite photos show ‘exponential’ heat dome as 250 die and AC price gougers cash in

https://www.independent.co.uk/climate-c ... 75368.html
Temperatures have soared close to 50C as the US Pacific north-west and Canada is gripped by a heatwave that has already contributed to dozens of deaths.

The sweltering heat is being caused by a “heat dome” according to meteorologists, as temperatures climbed to 49.5C in Lytton, British Columbia, on Tuesday.

In Vancouver, the police department said it had redeployed dozens of officers and asked the public to call 911 only for emergencies because heat-related deaths had depleted frontline resources and delayed response times.

The force added that it had already responded to 130 sudden deaths since last Friday. In total, nearly 250 deaths have been reported across the Pacific Northwest

In the American west, temperatures hit a high of 46C in Portland, Oregon, as roads buckled, schools were closed and large wildfires continue to burn in the region.

Satellite photos from NASA showed the extraordinary temperatures in the Pacific Northwest compared to that of other portions of North America, as residents continue to grapple with record-breaking temperatures.

After smashing Canadian heat records over three consecutive days, Lytton, BC, burns to the ground in a wildfire.
After a dangerous fire forced all residents of a small B.C. village to evacuate their homes Wednesday evening, the province's solicitor general says some people are still unaccounted for.

Mike Farnworth spoke about Lytton's devastating blaze at a last-minute news conference Thursday.

"Because the fire hit so fast, people evacuated very quickly, about 1,000 people," he said

Surface temperatures in Siberia heat up to a mind-boggling 118 degrees
It's not just the Western region of the US that's sweltering right now. Siberia in Russia is baking, and satellites are bearing witness to a brutal heat wave above the Arctic Circle. Copernicus Sentinel-3A and Sentinel-3B satellites captured a snapshot of land surface temperatures on June 20, and it was hot.

According to NASA, "Land surface temperature is how hot the 'surface' of the Earth would feel to the touch in a particular location." The Sentinel image shows a peak ground temperature of 118 degrees Fahrenheit (48 degrees Celsius) near Verkhojansk, a small town usually known for its extreme cold temperatures.

The World Meteorological Organization has been tracking the rise in temperatures around the world. "The most dramatic change is in the Arctic, which is warming more than twice as fast as the global average," the agency said Monday in a statement aimed at raising awareness of the urgency to act on the climate crisis.
