Canadian permafrost begins to melt seventy years early

During an expedition, a team of researchers from the University of Alaska at Fairbanks found that the unusually hot summer has quickly softened the upper layers of the massive underground ice blocks, which had been frozen for thousands of years.

“It’s an indication that the climate is now warmer than at any time in the last 5,000 or more years,” Vladimir E. Romanovsky, a professor of geophysics at the university, told Reuters by telephone. Their research results were published in the science journal Geophysical Research Letters.

The study was based on the data that Romanovsky and his colleagues had been analysing since their last expedition to the area in 2016. The group of researchers accessed the remote area by plane and found that the landscape had changed beyond recognition in the approximately ten years since the first time they had seen it.

The soil is covered in little hillocks
with small ponds between them,
the so-called thermokarst, which are created as permafrost melts and the surface collapses, and the previously sparse vegetation is burgeoning in the depressions that are protected
against the constant wind.

Scientists are alarmed by the instability of permafrost because fast melting could release great quantities of greenhouse gases, which may accelerate global warming further.

Icelandic glacier to be remembered by monument

A monument is to be erected to honour the glacier that was first lost to global warming in Iceland. The plaque will feature a note to future generations, as well.

The brutal price of air conditioning

According to the 2018 global report of the International Energy Agency, demand for air conditioning will triple by 2050, which will increase electricity consumption and carbon dioxide emissions and thereby accelerate the rate of global warming.

Terrible damage to aquatic ecosystems

The situation is worse than we thought – not only in the case of coral reefs, but also in freshwater fish populations.

Warming will claim many lives

Scientists have studied mortality data in 27 Chinese cities with high population densities to get an accurate estimate of the effect that global warming of 2 instead of 1.5 degrees Celsius would have on the mortality rate.

Climate change is destroying hundreds of reindeer

Scientists at the Norwegian Polar Institute have found an unprecedented reduction in Svalbard’s population of reindeer in 2019.

Lake found at 3400 metres in the Alps

Alpinist Bryan Mestre took an astonishing photo at the end of June, showing a lake in the French Alps that was probably created due to the heat wave that swept Europe.

Over 28 thousand species threatened with extinction

28,338 species on the planet are threatened with extinction according to the latest red list of the International Union for Conservation of Nature.

Astonishing record from beyond the Arctic Circle

The absolute temperature record was broken at one of Canada’s northernmost weather stations: 21 degrees Celsius was measured in Nunavut District beyond the Arctic Circle.

July set to be the hottest month ever recorded

According to data from NASA, this year’s was the hottest ever month of June, and July is well on the way to setting the record for the hottest month ever.
