*Extreme heat breaks temperature records across Europe | DW News*
132,084 views Jul 19, 2022 The United Kingdom on Tuesday provisionally
recorded its hottest-ever temperature reading, with the mercury rising
above 40 degrees Celsius (104 degrees Fahrenheit) for the first time. A
temperature of 40.2 C was recorded at London Heathrow shortly before
noon GMT, according to the Met Office weather service. The
record-breaking day follows the UK's warmest-ever night, with
temperatures in some regions remaining above 25 degrees Celsius (77
Fahrenheit) from Monday to Tuesday, according to the Met Office. The 40
C mark was announced shortly after the day's first record-breaking
reading of 39.1 C was provisionally recorded at Charlwood in the
southern Surrey region. The UK's previous all-time record high of 38.7 C
(101.7 F) was set in 2019. Tuesday's record could be broken again as the
day goes on, with temperatures expected to continue rising in the
afternoon.
On the other side of English Channel, several towns and cities in France
recorded their highest-ever temperatures on Monday. Saint-Brieuc, on the
normally temperate coast of Brittany, topped 39.5 C. The western city of
Nantes recorded 42 C, beating a decades-old high of 40.3 C set in 1949.
In southwestern France's Gironde region, two large wildfires raging for
a week across dry pine forests have forced the evacuation of 32,000
people. The blazes have already destroyed a total of 190 square
kilometers (more than 70 square miles) of forest. Fire officials said
strong winds and heat are fanning the flames, despite the deployment of
waterbombing aircraft.
Germany's weather service (DWD) said Tuesday that parts of the country's
west could crack the 40 C mark, putting the all-time temperature record
of 41.2 C recorded in 2019 within reach. The DWD said the extreme heat
is centered on the Western states of Saarland, Rhineland-Palatinate and
North Rhine-Westphalia, especially including low-lying areas on the
Rhine and Ruhr rivers. Areas of Germany have also raised forest fire
alert levels. In 10 of Germany's 16 states, predominately in the south,
west and northeast, the highest of five alert stages has been issued.
The Bavarian forestry minister has called on the public to be especially
careful when walking through forests, warning that even a single
cigarette butt can ignite an inferno.

*Record UK temperatures fuel climate change fears - BBC News*
69,076 views Jul 19, 2022 The UK has recorded record temperatures
above 40C for the first time, heightening concern over the impact of
global climate change.
Thermometers hit 40.3C at Coningsby in Lincolnshire while dozens of
other locations exceeded the UK’s previous highest recorded temperature
of 38.7C.
Fire services declared major incidents after a spate of blazes. Some
rail services were cancelled after tracks overheated or buckled and
overhead cables failed.
The Met Office chief of science and technology Prof Stephen Belcher said
exceeding 40C in the UK was "virtually impossible" in an undisrupted
climate. However global warming due to greenhouse gas emissions meant
extreme temperatures had become common.
The world has already warmed by about 1.1C since the start of the
industrial era and climate scientists say that temperatures will keep
rising unless governments around the world make steep cuts to emissions.

/[ Melting ice - recent paper published from cryologist Dr. Jason Box ] /
*Greenland Ice Sheet Rainfall, Heat and Albedo Feedback Impacts From the
Mid-August 2021 Atmospheric River*
Jason E. Box, et al
2 June 2022 - - https://doi.org/10.1029/2021GL097356
*Abstract*
Rainfall at the Greenland ice sheet Summit 14 August 2021, was delivered
by an atmospheric river (AR). Extreme surface ablation expanded the
all-Greenland bare ice area to near-record-high with snowline climbing
up to 788 ± 90 m. Ice sheet wet snow extent reached 46%, a record high
for the 15–31 August AMSR data since 2003. Heat-driven firn deflation
averaged 0.14 ± 0.05 m at four accumulation area automatic weather
stations (AWSs). Energy budget calculations from AWS data indicate that
surface heating from rainfall is much smaller than from either the
sensible, latent, net-longwave or solar energy fluxes. Sensitivity tests
show that without the heat-driven snow-darkening, melt at 1,840 m would
have totaled 28% less. Similarly, at 1,270 m elevation, without the bare
ice exposure, melting would have been 51% less. Proglacial river
discharge was the highest on record since 2006 for late August and
confirms the melt-sustaining effect of the albedo feedback.
Key Points
-- A mid-August 2021 Greenland atmospheric river (AR) produced extreme
ice sheet snow cover changes and high proglacial river discharge
-- Surface heating from rainfall is small compared to latent and
sensible heating, net longwave radiation or sunlight absorption
-- Melt-albedo feedback enhanced upper elevations snow melt under clear
skies following the heating delivered by the AR
*Plain Language Summary*
While rainfall at Summit station atop of the Greenland Ice Sheet in
mid-August 2021 captured global attention, its direct surface
thermal effects were weak and unable to explain the major melt and
river discharge that occurred during and after the event.
Exceptional heating of the ice sheet first occurred due to the heat
transfer from condensation and the elevated air temperature during
an atmospheric river (AR) episode. Satellite measurements reveal a
rapid retreat of the snowline to higher elevations, exposing a large
extent of relatively dark bare ice. Where snow remained, darkening
due to wet snow metamorphism was responsible for sustained
additional solar heating of the upper ice sheet elevations for the
following 2 weeks. Observations from automatic weather stations and
satellites, and river gauging, reveal that the AR had an immediate
and sustained impact.

/*July 20, 2006*/
July 20, 2006: NPR reports on the GOP's show trials, er, hearings
regarding climate research in the House Committee on Energy and Commerce.
A congressional committee took up the topic of global climate change
Wednesday, focusing on an eight-year-old study suggesting that the world
is warmer now than it has been in a thousand years. Congressman Joe
Barton (R-TX) used the hearing to question the study and the debate over
global warming.
