Climate change could destroy mankind by 2050

We have known for a long time that global warming is jeopardising the future of humanity on planet Earth. However, a new study about the survival chances of the human species paints a bleaker picture than seen ever before: unless we do everything to avoid such a fate, we could be on the brink of extinction in 30 years.

The report, published by the Australian organisation Breakthrough National Center for Climate Restoration and written by climate researchers David Spratt and Ian Dunlop paints a dark future for mankind unless we are able to curb the consequences of climate change in the next three decades.

“After nuclear war, human-induced global warming is the greatest threat to human life on the planet,”

said Chris Barrie, former head of the Australian Defence Force, in the foreword to the paper. Although he doesn’t believe that destruction of human civilization is unavoidable, he does claim that avoiding it requires immediate action.

The study has used the results of previous research to model potential scenarios – of which the most pessimistic one is more than alarming. If the global temperature was to rise by 3 °C relative to the period before the industrial revolution, the consequences would be dire:

  • On 35% of Earth’s land area (currently home to 55 percent of the human population) heat waves that are physiologically incompatible with human survival would last 20 days a year.
  • In West Africa, South America, the Middle East and Southeast Asia, there would be more than 100 days a year of deadly heat, which would mean that more than a billion people would have to move from those areas.
  • Rising water levels would erase many cities around the world.
  • Food production would collapse due to the drastic decline of insect populations that play an important role in agriculture, the climate becoming unsuitable for plant cultivation and chronic water shortages.
  • Many large ecosystems of the world (the Arctic, Amazonia and the coral reefs) would also collapse.

This is not the only recent study that has reached the conclusion that a global catastrophe developing as a result of the climate crisis is a realistic possibility. The autumn 2018 report of the Intergovernmental Panel on Climate Change (IPCC) and the March 2019 UN report also made similar predictions.

Corals back from the dead discovered in the Mediterranean Sea

For the first time ever, living polyps were discovered in Mediterranean coral colonies that were previously thought to be completely dead by researchers who published their finding in the periodical Science Advances.

Oceans absorb massive quantities of carbon dioxide

The oceans play a very important role in controlling Earth’s climate. New research has shown that the planet’s five oceans absorb much more carbon dioxide, one of the gases responsible for the greenhouse effect, than previously thought.

Temperatures in Israel increase by 0.25 degrees Celsius per decade

According to a study published in the International Journal of Climatology, Israel’s average temperature has been rising continuously since the proclamation of the Middle Eastern state in 1948, but over the last thirty years the rate of warming has also increased.

Temperatures increase much faster than global average in the Mediterranean region

Temperatures are rising much faster than the global average in the region of the Mediterranean Sea, and this represents a threat to the food and water resources of the region, researchers have warned in a new study.

Fates, faces, contrasts

The news about climate refugees are alternating sequences of frightening numbers and apocalyptic landscapes that obscure the real face of the problem: the disfigured human fates.

Climate change causing great damage to UK wildlife

More than a quarter of all mammals are threatened with extinction.

Several hundred temperature records broken in 2019

Between 1 May and 30 August, higher than ever temperatures have been measured in 29 countries, on almost 400 occasions in the Northern Hemisphere.

The perishing glaciers of the Alps – shown from a special perspective

The Polarstern sets off on a unique expedition frozen to an ice floe

The ice floe that the German research boat will be attached to as it drifts around the Arctic for almost a year on the most important Arctic expedition ever has been selected.

September 2019 the warmest so far

Data from European climate researchers indicates that this year’s was the warmest September since the Copernicus Climate Change Service began keeping regular records of meteorological data in 1981.
