Only 2 Degrees Separates Mankind from the Climate Catastrophe

According the IPCC Final Draft of the report, which full name is Global Warming of 1.5°C, an IPCC special report on the impacts of global warming of 1.5°C above pre-industrial levels and related global greenhouse gas emission pathways, in the context of strengthening the global response to the threat of climate change, sustainable development, and efforts to eradicate poverty, the global temperature is highly likely to increase more than 2°C by the end of the century.

Among the possible outcomes of the global temperature increase are the sea level rising, the dropping in GDP, the global starvation and the lack of drinking water,  super droughts, increasing wildfires, intense hurricanes and the melting of the Arctic, scientists say. 

For human beings rising temperatures and shifts in weather could mean reduced air quality, food and water contamination, more infections carried by mosquitoes and ticks and stress on mental health.

“It is quite obvious that there are colossal changes in the climate on Earth in the event of a temperature increase of 2 degrees. We must avoid them,” said senior lecturer at the University of Bristol Dan Mitchell.

According to different studies using entirely different methods and all climate models published in the Nature Climate Change journal there is a slim chance of avoiding a 2-degree global temperature increase.

The climate modeling shows that Earth will continue to heat up about two more degrees by 2100. If different emissions of greenhouse gases and the burning of fossil fuels continue for 15 more years, Earth's global temperature could rise as much as 3 degrees.

"Even if we would stop burning fossil fuels today, then the Earth would continue to warm slowly," said the author of one of the studies Thorsten Mauritsen. "It is this committed warming that we estimate."

WHAT HAPPENS NOW AND WHAT WE ARE GOING TO DO IN THE FUTURE

Today the temperature on the globe has risen by one degree. As a result, according to the World Health Organization that 12.6 million people die globally due to pollution, extreme weather and climate-related diseases. The climate change between 2030 and 2050 is expected to cause 250,000 additional global deaths, according to the WHO.

Researchers said that the changing public policy is the key driver of changing this situation.

"Are we going to get to work installing clean energy, or stick to old polluting sources? If we don't act quickly, we better get to work preparing for many severe consequences of a much hotter world." said Dargan Frierson, one of the authors of the study.

"There are only 2 realistic paths toward avoiding long-run disaster: increased financial incentives to avoid greenhouse gas emissions and greatly increased funding for research that will lead to at least partial technological fixes," said Dick Startz, an economist and global warming expert.
