The melting of glaciers: was the maths all wrong?

What if the mathematical models that we use today to estimate the impacts of climate change are wrong? What if the situation is even worse than we thought?

According to a study published in Science, current models underestimate the effect of warming sea water on the underwater melt of glaciers: under the water, the ice of glaciers is melting a hundred times faster than previously thought, whereby sea level rise may also be even more drastic.

Instead of using estimates based on mathematical models, researchers from the University of Oregon actually measured the underwater melting of the LeConte Glacier in Alaska. Co-author Rebecca Jackson likened underwater melting to a “spark” that accelerates the melting of glaciers a great deal, something that has not been taken into account in the models at all.

Dachstein Glacier melting at an alarming rate

Immediate climate protection measures are required, said Rudi Anschober, an Austrian politician responsible for environmental protection after an on-site inspection.

Man-made sand dunes protect Britain against sea level rise

Massive sand dunes are being built along a section of East Anglia’s shores to protect 400 homes against storm waves. This is the first such attempt in the United Kingdom to protect against the effects of sea level rise and to prepare for climate change.

Devastating floods in Asia

The June to September rainy season is vital for agriculture and for the replenishment of water reserves, but the heavy rains also do a great deal of harm each year.

Norwegian glaciers threatened by the heat wave

The heat wave that has swept Europe has reached also Norway. Researchers say the record temperatures in excess of 30 degrees Celsius may result in some of Norway’s glaciers disappearing completely within a few years.

The heat is breaking up Greenland’s ice sheet

Researchers claim that the hot air flowing north from North Africa has “smashed” European weather records in the second half of July, as in some places previous temperature records were surpassed by up to 4 degrees Celsius.

High water

If the people of a country only try to imagine how rising sea levels could transform our world as we know it today by looking at the map, the risk remains an incomprehensible, surreal abstraction.

The tragedy of climate change is playing out in South Asia

An increasingly urgent problem that, however, only casts shadows on the distant future for the residents of the developed world has already cost hundreds of lives in South Asia and it is threatening a much more severe refugee crisis than any seen so far.

Annual sea level rise revealed

According to a new study based on satellite measurements by a research group from the Technical University of Munich and the Technical University of Denmark, sea levels in the Arctic region have risen 2.2 millimetres a year on average.

Water crisis: millions at risk in India

The floods brought on by monsoon rain in the north and west of India impact the lives of more than four million people: the destructive waters have claimed lives, and the residences of hundreds of thousands were put at risk by the natural disaster.

Indonesia has lost land equal to the size of Jakarta

Over the last 15 years, Indonesia has lost 29,261 hectares of its land surface area due to soil erosion and growing sea levels.
