Hot Heatwave News 1

Hot heatwave news daily, through June, July and on into August. The turnaround in weather and water since the early spring is unbelievable. Despite a brief lull and the wet Sunday at the end of July, real worries about drought entering August. Not just in the UK, but Ireland, Scandinavia and yet again continental Europe. It's coming from a particularly persistent, blocked weather pattern, with high pressure over these areas for much of June and July and weak jetstream running further north than usual. The heatwave further aggravated by drying soils, so no evaporative cooling. Comparisons in Britain and Europe with the hot summers of 1976 and 2003. The particularly disturbing thing is the heatwave is planet-wide; the jetstream weak and slow moving all around the northern hemisphere, making for blocked weather over Siberia; 30C+ north of the Arctic Circle in Finland. Heatwave in Scandinavia, Iberia, Canada, Japan. In Japan, too, exceptionally intense rainfall bringing flooding. Wildfire in NW England, Sweden, California. Disturbing again is that this doesn't look as if it will be a one-off. Not if anthropogenic climate change predictions are to be believed, which they should be. It's crazy and scary that lots of people, including some very powerful people say they shouldn't be. The carbon dioxide shortage in June affecting food and drink industries in Britain and Europe was ironic, given that atmospheric carbon dioxide concentration is now above 400ppm and rising. When I started secondary school and learned about the constituents of the Earth's atmosphere in the early 1980s, it was about 320ppm. The mean global temperature is already 1C above that at the beginning of the Industrial Revolution and the rate of increase is accelerating. If it's not global heating that's driving the extremes of heat, drought and intense rainfall seen in globally since the beginning of this century, I don't know what else is. Somthing must be up, or down.

Guardian 13/07/18 - global heatwave / record temperatures in many areas. Climate change inducing more blocking weather, prolonging episodes of heat and drought. La Nina this year. Should be cooler, not continuation of upward trend seen this decade.






The 2018 Great Britain and Ireland heat wave is a period of unusually hot weather that has led to record-breaking temperatures in the UK and Ireland,[1] and has helped to cause widespread drought, hosepipe bans, crop failures, and the 2018 United Kingdom wildfires.
A heat wave was officially declared on 23 June, with even Scotland and Northern Ireland recording temperatures above 30 °C (86 °F) for the first time since the July 2013 heat wave, something which is rare in these places, but more common in England and Wales.[2]
The British Isles are in the middle of a strong warm anticyclone inside a strong northward meander of the jet stream. It is part of a larger heat wave affecting the northern hemisphere, caused by the jet stream being farther north than usual, trapping hot air above North America, Europe, and Asia, and blocking low-pressure systems that would bring cooler air and rainfall.
t is part of a heat wave spanning the Northern Hemisphere, which has seen the hottest night ever recorded on Earth in Oman, where the lowest temperature was 42.6 °C (108.7 °F),[11] and the deaths of at least 33 people in Canada.[10]

Temperature
In Wales and Northern Ireland, June 2018 was the warmest June ever recorded and in England and Scotland, June 2018 ranks within the top 5 warmest on record.[23] In the Central England region, the CET is a long running temperature series, with records back to 1659. 2018's temperature was 16.1 °C (61.0 °F), meaning it ranks as the 18th warmest June recorded in England in the past 359 years, also being the warmest since 1976.[24]


Much of northern Europe has been experiencing a heatwave - notable for its intensity and duration. It's caused by "atmosphere blocking". Can we predict when these blocks will come and how long they will last? Adam Rutherford talks to Jana Sillmann, director of the Centre for International Climate Research in Oslo, Norway, author of a new study that has modelled 40 years' worth of heatwaves and blocking, and looked to the end of the century in attempting to predict blocking patterns as the climate changes.

FB 20/07/18:
It was above 90°F north of the Arctic Circle on July 18, 2018 in northern Finland -- more than 30°F warmer than a normal mid-July day.
PEOPLE are rapidly impacting the Earth's climate, and the Arctic is the most rapidly changing place on the planet. We need to do something!!

It is very very hot in Japan right now.
Sadly, this type of deadly heatwave is going to become more common as anthropogenic climate change keeps marching on. (H/T twitter: @HakimAbdi)

  
https://www.dwd.de/DE/wetter/thema_des_tages/2018/7/22.html - German weather service 22/07/18 - average temperatures across Germany not as hot as summer 2003 (yet), but heat set to build this week. (Also drought problems in Germany, Holland and Belgium.) Summer heatwave city temperatures around Germany compared with averages from 1961 onwards: 2018 stands out high by a large, well above average in Frankfurt and Berlin, but not all.

https://www.theguardian.com/world/2018/jul/22/heatwave-northen-hemisphere-uk-algeria-canada-sweden-whats-the-cause - Observer 22/08/18 - cause of heatwaves is the jetstream weak and slow all around the northern hemisphere, enabling blocking high pressure systems to persist for weeks on end.

Hitze in Deutschland – der eine freut sich über das hochsommerliche Wetter, für den anderen können die hohen Temperaturen zur (gesundheitlichen) Belastung werde...
Heat in Germany - the one is happy about the summer weather, for the others, the high temperatures can become the (Health) burden. Overall, the number of hot days has risen in recent decades, and in the future there will be more heat waves in the future.

With the consequences, especially cities have to fight - that is why we encourage measures to adapt to climate change, such as concepts for more city green and outdoor cleared, an appropriate building and event, as well as safe drinking water supply: www.bmu.de/PM7885

It is also clear: to prevent even stronger and more serious consequences of climate change, we must move forward in climate change. That is why we are going to put a climate protection law on the way, which, for the first time in Germany, is legally binding and binding on us to achieve our climate targets by 2030
