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.

The moment caught in the act – Ice melting through the eyes of a nature photographer

“Ice is the canary in the global coal mine. It’s the place where we can see and touch and hear and feel climate change in action.” Internationally recognised nature photographer James Balog believes it is extremely important to pay attention to the processes underway in the polar regions.

Dutch use innovative device to protect against sea level rise

Rising sea levels caused by climate change and global warming are an increasing threat to the Netherlands, so the Dutch have started using an innovative device, a storm surge barrier to protect against them. The world’s largest storm surge barrier was built in the south of the country, at Maeslantkering.

Switzerland’s glaciers have lost 10 percent of their ice mass in five years

The melting of glaciers has broken new records in Switzerland this year; they lost two percent of their ice mass this summer, while over the last five years, they have lost 10 percent of their volume altogether, which is unprecedented in the existing records spanning over 100 years.

Typhoon Hagibis wreaks tremendous destruction

The typhoon raging in Japan has claimed more than fifty lives; the number of injured has exceeded two hundred.

Hurricanes, typhoons, cyclones – what’s the difference?

As a result of climate change, humanity is expected to face growing numbers of destructive storms in the future.

An important agricultural region is the latest victim of climate change

The rising sea levels and melting permafrost caused by climate change are causing crisis situations in a number of places around the world, resulting in tens of thousands of people having to leave their homes, while important agricultural areas also fall victim to the changes.

A new sign of the climate crisis: tens of thousands of meltwater lakes were found in Antarctica

Climate change is causing severe problems in Antarctica, too: recently, a piece of ice weighing 315 billion tonnes broke off the area, while scientists investigating satellite images covering an area of 5 million square kilometres found tens of thousands of meltwater lakes, which indicates severe problems.

State of emergency declared in Montana due to early snow

Massive snowstorms hit a number of north-western and northern states of the USA on 29 September.

Monsoon claims over a hundred lives in India

Monsoon rain accompanied by storms and lightning hit the states of Uttar Pradesh and Bihar in India on 27 September. Tempestuous winds toppled trees and utility poles and tore off roofs, killing more than a hundred people.

Mont Blanc glacier in Italy threatened to collapse

On 24 September, the Fondazione Montagna Sicura (Safe Mountain Foundation) issued an avalanche warning on the Planpincieux Glacier, which is located on the eastern slope of the Grandes Jorasses peak.
