A fierce drought melted glaciers during Europe's hottest recorded summer last year, a phenomenon that could repeat as the continent warms at nearly twice the global rate, the EU's climate observatory said Thursday.
Two-thirds
of Europe's rivers fell below average levels and five cubic kilometres (two
cubic miles) of ice disappeared from Alpine glaciers, the Copernicus Climate
Change Service (C3S) said in its yearly update.
With
human-caused emissions heating the planet, Europe is warming around twice as
quickly as the world average -- 2.2 degrees Celsius over the past five years
compared to the pre-industrial era.
In 2022
it saw its second-hottest year and its hottest summer since comparable records
began in the 1950s, said Copernicus, which monitors numerous climate indicators
via satellites plus land- and sea-based instruments.
The
forecast for 2023 remains uncertain but "with higher concentrations of
greenhouse gases in the atmosphere, the probability of more warm years
continues to increase," said Samantha Burgess, deputy director of C3S.
With
soils in southern Europe still "incredibly dry", impacts will be felt
this year "unless we have significant spring rainfall," she added.
"Unfortunately
the impacts are probably already in place for growing season. So we're likely
to see reduced crop production this year because of the dry winter and spring
period."
Drought
in Europe
Copernicus
had earlier announced that the past eight years have been the hottest on
record.
It found
2022 "another record-breaking year in terms of greenhouse gases concentration,
temperature extremes, wildfire and precipitation, which have all had a notable
impact on both ecosystem and community all over the continent," said C3S
director Carlo Buontempo.
"We
are really moving into uncharted territory."
The
continent had less snow and rain than average in winter 2021-2022, followed by
prolonged heatwaves in the summer which hit the agriculture, river transport
and energy sectors.
River
levels were the second-lowest on record with nearly two-thirds of Europe's
rivers below their average level.
The
heatwaves drove wildfires, with carbon emissions from such summer blazes the
highest since 2017 across the EU.
"The
lack of winter snow and the high summer temperatures resulted in a record loss
of ice from glaciers in the Alps, equivalent to a loss of more than 5km3 of
ice," the report said.
Southern
Europe experienced a record number of days with "very strong heat
stress" on the human body.
Emissions
reductions
Copernicus
said satellite measurements of major greenhouse gases in the atmosphere reached
their highest level on record in 2022.
Under
the 2015 Paris Agreement, countries have pledged to slash their use of fossil
fuels with the aim of reaching "net zero" emissions of these gases to
limit the rise in global temperatures to 1.5C.
Global
temperatures in 2022 were 1.15C above the pre-industrial average, according to
the World Meteorological Organization.
Copernicus
meanwhile calculated that Europe in 2022 received its highest amount of surface
solar radiation in 40 years -- a boon for renewable electricity production.
The heat
in non-summer months reduced demand overall for electricity as less was needed
for heating, it said. In southern Europe demand rose however as people cranked
up the air conditioning.
Climate
think tank Ember calculated in a report this month that solar and wind energy
surged to make a record 12 percent of the world's electricity in 2022. It
forecast emissions from fossil fuels would peak in 2023.
"We
have many adaptation options available today by changing supply and
demand," said Daniela Schmidt, earth sciences professor at the University
of Bristol, commenting on the Copernicus report.
"Some
of these are investments into our infrastructure which will take lead time, but
they also include teaching people and companies about land cover change, water
savings and efficiency."
