PARIS, Sept 6, 2023 (BSS/AFP) - 2023 is likely to be the hottest year in

human history, and global temperatures during the Northern Hemisphere summer
were the warmest on record, the EU climate monitor said on Wednesday.

Heatwaves, droughts and wildfires struck Asia, Africa, Europe and North
America over the last three months, with dramatic impact on economies,
ecosystems and human health.

The average global temperature in June, July and August was 16.77 degrees
Celsius (62.19 degrees Fahrenheit), smashing the previous 2019 record of
16.48C, the European Union's Copernicus Climate Change Service (C3S) said in
a report.

"The three months that we've just had are the warmest in approximately
120,000 years, so effectively human history," C3S deputy director Samantha
Burgess told AFP.

Last month was the hottest August on record and warmer than all other months
except July 2023.

Climate breakdown has begun," said UN Secretary General Antonio Guterres.

"Scientists have long warned what our fossil fuel addiction will unleash," he
added. "Our climate is imploding faster than we can cope, with extreme
weather events hitting every corner of the planet."

Record-high global sea surface temperatures played a major role in stoking
heat throughout the summer, with marine heatwaves hitting the North Atlantic
and the Mediterranean Sea.

"Looking at the additional heat we have in the surface ocean, the probability
is that 2023 will end up being the warmest year on record," Burgess said.

The average global temperature through the first eight months of 2023 is the
second-warmest on record, only 0.01C below the benchmark 2016 level, the
report added.

If the Northern Hemisphere has a "normal" winter, "we can almost virtually
say that 2023 will be the warmest year that humanity has experienced,"
Burgess said.

- Warming oceans -

Oceans have absorbed 90 percent of the excess heat produced by human activity
since the dawn of the industrial age, according to scientists.

This excess heat continues to accumulate as greenhouse gases -- mainly from
burning oil, gas and coal -- build up in the Earth's atmosphere.

Excluding the polar regions, global average sea surface temperatures exceeded
the previous March 2016 record every day this summer from July 31 to August
31.

The average ocean temperature has been topping seasonal heat records on a
regular basis since April.

Warmer oceans are also less capable of absorbing carbon dioxide (CO2),
exacerbating the vicious cycle of global warming as well as disrupting
fragile ecosystems.

Antarctic sea ice remained at a record low for the time of year with a
monthly value 12 percent below average, "by far the largest negative anomaly
for August since satellite observations began" in the 1970s, C3S said.

Higher temperatures are likely to come: the El Nino weather phenomenon --
which warms waters in the southern Pacific and beyond -- has only just begun.

Scientists expect the worst effects of the current El Nino to be felt at the
end of 2023 and into next year.

At the 2015 Paris climate summit, countries agreed to keep global temperature
increases to "well below" 2C above pre-industrial levels, with an
aspirational target of 1.5C.

A report by UN experts due this week will assess the world's progress in
meeting the goal and will inform leaders ahead of a high-stakes climate
summit in Dubai starting on November 30.

The so-called "Global Stocktake" is expected to show that countries are well
behind meeting their commitments.

"Surging temperatures demand a surge in action. Leaders must turn up the heat
now for climate solutions," said Guterres.

The C3S findings came from computer-generated analyses using billions of
measurements from satellites, ships, aircraft and weather stations around the
world.

Proxy data such as tree rings and ice cores allow scientists to compare
modern temperatures with figures before records began in the mid-19th
century.
