HEAT Waves 2018

Maybe this should be under a new thread, perhaps 'climate whiplash'?

But I'll dump it here for now:

Unprecedented Change From Cold April To Hot May

Did you freeze your a– off in April? Did you sweat your a– off in May? Well, you are not alone. In fact, a record number of stations observed a record cold April followed by a record warm May. This is the largest area on Earth to experience a record cold to record warm flip (or vice versa) of temperatures in consecutive months in the last 100 years!…

If the whiplash from cold to hot seemed unusual, it was. In fact, it was unprecedented for any time of year. Using the NASA GISS temperature gridded data set, approximately 130,000 square miles went from record cool to record warm from April to May in 2018. The next largest “event” was the transition from record cold to record warm from December 1946 to January 1947, in the tropical Pacific Ocean southeast of Hawai’i (107,000 square miles). Given that it occurred over the ocean, I find this a little dubious.

We had a record-setting late blizzard in April followed by a record-setting string of days in the 90's and 100's in May. A very bizarre spring!

Did others experience similar temperature whiplash between April and May this year?

We arrive in Newfoundland on June 30. Here are some pics of the weather two days ago, Tuesday June 26. Worth glancing at. Remember we are coming from Grenada for summer vacation.

Irish Water lowers night-time water pressure in Dublin as temperatures reach 32C
https://www.rte.ie/news/weather/2018/06 ... r-ireland/
Met Éireann has confirmed that the highest temperature since 1976 - 32 degrees Celsius - has been recorded this afternoon at Shannon Airport.

The heat is threatening drought conditions in many parts of the country and a Status Yellow temperature warning remains in place until tomorrow evening.

Met Éireann said the country was in a "heatwave situation". A heatwave is defined as five continuous days of temperatures above 25C.

Irish Water has announced additional measures to protect the water supply in the Greater Dublin area.


A few fine days and we have a drought, this country has very limited water storage because it's nearly always raining.
But now it isn't

Newf, wow! I had seen a headline about that freakish storm, but hadn't seen any pictures. Happy summer!! :shock: 8O :? :-D

Hang in there dolan. About scores of millions of us State side are facing some pretty fierce temps, too:

U.S.: Nearly 60 million people are under some type of heat watch, warning or advisory from the National Weather Service as the worst heat wave of 2018 arrives.

More than 120 million people will see the temperature climb above 95 degrees F (35°C) during the next week.

Worst heat wave of the year grips Midwest, Northeast


Unfortunately, not everyone in these northern climates has the luxury of central air. According to the US Energy Information Administration, about 2 million household units across the Midwest do not have air-conditioning equipment.

Overnight low temperatures are expected to dip only into the upper 70s, which does not allow buildings (and their occupants) much of a chance to cool off. It is the lack of overnight cooling that has proved deadly in past Midwest heat waves.

Does anyone else care to chime in and share how things are looking in their neck of the woods?

(Also, for a bit of perspective: On Tuesday, the LOW temperature in Quriyat, Oman was 42.6 °C (108.7 °F) — a new global record.

Sorry New Yorkers, this heat wave ain’t going anywhere soon
If you think your 4th of July plans will be the hottest thing about this week, you’ve got another thing coming.

And still...it persisted!

Dangerous heat wave won't let up across U.S.


Extreme heat and humidity will continue through the end of the holiday week across the eastern U.S., before it shifts westward, roasting the Midwest and Great Plains, potentially setting records and intensifying ongoing wildfires all the way to California.

Why it matters: Heat is the top weather killer in the U.S. during most years. According to the Centers for Disease Control and Prevention, more than 600 people are killed every year due to heat-related illnesses in the U.S.
...
Historical context: The actual air temperatures during this heat wave are not smashing all-time records in most cases, since they're only 10 to 20 degrees Fahrenheit above average for this time of year. However, the combination of heat and humidity, plus the long duration of this event, make it a public health threat.

Daily high temperature records have fallen in some places, along with records for the highest overnight low temperature. Research has shown when air temperatures fail to cool below about 80 degrees Fahrenheit overnight, the risk of heat-related illnesses, including heat stroke, increases. On Sunday night into Monday morning, the temperature failed to drop below that 80-degree threshold in New York City and other locations along the East Coast.

What's next: The heat should peak along the East Coast on Monday, but high temperatures all week are likely to reach or exceed 90 degrees Fahrenheit from the Mid-Atlantic to New England, which may put this event in the top 10 for long duration heat events.

Meteorologists define heat waves as occurring once the temperature hits or goes above 90 degrees for at least three consecutive days. Many locations in the East are on their fourth or fifth such day as of Monday, with no relief expected until next weekend.

A Lengthy European Heat Wave Will Enter Its Second Week As July Begins

That kind of warmth doesn’t seem unusual to those of us across the Atlantic, but many homes in western Europe aren’t air conditioned and the effects of prolonged heat can quickly become a problem for vulnerable populations.

Lets hope the denoument is not as deadly as areas of and around France when thousands perished due to heat wave some years back

Heat wave gripping the country enters 5th day with no relief in sight
As the July Fourth holiday weekend approaches, millions are trying to deal with the oppressive heat sweeping the nation. Those on the East Coast are waking up to day five of the prolonged heat wave, while those in Los Angeles are expected to see temperatures above 100 degrees, NBC’s Stephanie Gosk reports for TODAY and Dylan Dreyer tells us what we can expect next.

It's my understanding total global CO² content in the atmosphere must not exceed 350 ppm without serious consequences. I just checked several sites and found it to be north of 400 ppm. Perhaps this has something to do with it??? Image

And wait till the oceans begin being sources of CO2 rather than sinks, then warming will go into overdrive 8O

Don't worry. The liberals have a solution. They can't get it together to support a carbon tax or take steps to banning cars or stopping the use of fossil fuels or even have a climate treaty that actually cuts CO2 emissions, but the liberals do have a solution.

The Ds in California and Seattle want to ban plastic straws. They say it will help stop global warming. Thats a pretty bold step there. I hope the Ds don't alienate any voters by supporting such a radical plan to cut CO2 emissions.

The Ds are taking action against climate change! No word on a carbon tax or limits on CO2 emissions, but they want to ban plastic straws! We are saved! I guess?

A little over 20 years ago we moved into our “new” house, I took a couple of weeks off to do some much needed repairs. Temps topped out over a 100 in Philly during that period.

There have always been heatwaves. Global warming just progressively makes them a little hotter, and they occur a little more often and they last longer.

According to NOAA, the west and the Great Lakes Region of the east should get hit the worst by global warming and heatwaves

Nice post, P.

They're feeling the (relative) heat in Siberia, too:

Extreme Heat Event in Northern Siberia and the coastal Arctic Ocean This Week

...an extreme heat event for this particular region…with high temperatures of greater than 40 degrees F above recent normals…will impact the coast of the Arctic Ocean (specifically the Laptev Sea and Eastern Siberian Sea) Wednesday-Friday. This will generate maximum daily temperatures as high as 90-95 degrees [F] near the open ocean coast!

Yes, you read that correctly.

Needless to say, a true roasting for this area.

I’ve looked over the European model and there appears to be general agreement over the intensity and timing of this extreme event. It is absolutely incredible and really one of the most intense heat events I’ve ever seen for so far north. Climate change has sent temps skyrocketing in the far north of the planet over just the past 20 years. While that’s been quite reflected in the rapid rise in wintertime temperatures, it’s increasingly being reflected in summertime temperatures as more and more sea ice disappears earlier in the season, leaving more dark blue ocean to absorb more daytime sunlight. This heating of the ocean surface by low albedo (very low reflectivity…little sunlight being reflected back off into space) causes some heat to be released back to heat the atmosphere above, speeding up warming of the Arctic region. This is known as Arctic Amplification. And one larger-scale hemispheric consequence being actively researched by Dr. Jennifer Francis (YouTube Video Presentation) and on others is that Arctic Amplification is causing an abrupt weakening of the polar jet stream (on timescales of just the past decade or two), the main feature which steers and intensifies weather patterns in the mid-latitudes. The weakening is causing the polar jet to become much wavier, with greater wave “breaks” and blocking patterns where waves sit in the same place for weeks promote extreme weather patterns (extreme cold relative to normal as well as extreme heat, very wet, and drought conditions).

2018 has unfortunately been a prime example of global warming’s effect on the jet stream. And northern Siberia has been getting blowtorched by heat that refuses to quit because of an ongoing blocked pattern favorable for intense heat...
