El Niño has not been this strong in centuries

Drought and forest fires, or on the contrary, massive storms and floods. The natural disasters caused by El Niño keep growing ever larger. The problem is already massive in Australia, Southeast Asia and America, but experts warn that the situation will get even worse in the future.

It is no novelty for scientists that El Niño, a natural phenomenon associated with the flow of the ocean, is exhibiting a trend of increasing intensity, but so far we had no suitable data to determine the changes of the occurrence exactly. A new study, however, for which samples were taken from deep in the cores of coral reefs, has provided more data about the last four hundred years of El Niño than we have ever had before.

Mandy Freund, a post doctoral fellow at the Center of Excellence for Climate Extremes, determined changes in climate patterns using coral samples which – similarly to the growth-rings of trees, hold information about the climate of recent centuries.

According to Freund, over the last
thirty years, the intensity of El Niño
has grown to unprecedented levels
for instance in the central Pacific,
and this has resulted in the increased frequency of extreme
weather anomalies.

The study, which the researchers published in the journal Nature Geoscience, is expected to facilitate preparation for future El Niño events and the modelling of their destructive impact.

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.
