Forecasts have proven too optimistic

Europe is warming up faster than expected, with climate change increasing the number of extremely hot days while reducing the number of extremely cold ones, reported researchers at ETH Zürich University in their study published in the journal of the American Geophysical Union, the Geophysical Research Letters.

The scientists found that since 1950, the number of extremely hot days has tripled in Europe, and summers have become generally warmer, while the number of extremely cold days has halved, and winters have also become warmer.

According to the study, some parts of Europe are warming faster than predicted in previous climate models. The researchers knew that Europe was warming, but previous research into extreme temperatures analysed longer-term trends.

In their new study, Ruth Lorenz and her colleagues used observational data from Europe’s meteorological stations between 1950 and 2018, and analysed the changes in the occurrence of hot and cold temperature extremes. 90 percent of the weather stations included in the study showed that the weather was getting warmer.

They found that extremely hot days have become 1.4 degrees Celsius warmer on average, while
extremely cold days
have become
3 degrees warmer.

The warmest and coldest nights have also warmed significantly, by more than the corresponding summer and winter mean temperatures. Drastically different temperature trends were detected in various regions of Europe. In Central Europe, for instance, days with extreme temperatures warmed by 0.14 degrees Celsius more than the summer mean each decade, resulting in an increase of almost 1 degree in the period studied, the science portal EurekAlert quoted Lorenz.

The ocean is too hot

From Alaska to California, the temperature of the Pacific Ocean is well above average.

Prague saying goodbye to a record hot summer

Since measurements began in Czechia almost two and a half centuries ago, there has not been a summer as hot as this year’s in Prague, when daily average temperatures reached 22.9 degrees Celsius.

UN High Commissioner: the world is in an alarming state

In her opening address at the 42nd Regular Session of the UN Human Rights Council, Michelle Bachelet, UN High Commissioner for Human Rights, expressed grave concern about the condition of the global environment.

Proposal to introduce the siesta in Germany due to climate change

Climate change is making Germany’s climate warmer, with a series of new high temperature records and heat waves making people’s lives more difficult. In response to the changes, the German Trade Union Confederation has proposed introducing the siesta break to protect workers.

Britain’s birds suffer the impact of climate change

Climate change will have a long-term effect on the future of a third of the bird species studied.

Russia is warming up at over twice the average rate

The country’s average temperature has increased by 0.47 degrees Celsius each decade since 1976.

Future is bleak for European skiing industry

The European skiing industry has to reckon with much less snow and much shorter seasons as a result of climate change. Skiing resorts are responding to the challenge by using snow cannons and employing innovative snow production technologies – a practice that environmentalists believe to be particularly harmful.

Dropping oxygen levels of the oceans to cause ecological crisis

It is a lesser known fact that climate change is also making the oxygen levels of the oceans drop. Over the last 50 years, the average oxygen content of the world’s oceans has dropped by almost 2%, which may have dramatic consequences.

Climate change presents new challenges for healthcare

A study by researchers at the University of Colorado claims that along with new types of psychological problems such as climate anxiety and ecological grief, climate change has many other unfavourable consequences for human health, such as the chronic kidney disease that is becoming increasingly common among agricultural workers.

New islands discovered in the Arctic Ocean – after a glacier melted

The hydrography research group of the Russian Navy’s Northern Fleet has discovered five islands in the region of Franz Josef Land in the Arctic Ocean, the website of the Russian news agency RIA Novosti reported.
