Global warming: NASA has been able to predict which regions of the world may become uninhabitable in 30 to 50 years.
Regions already exposed to global warming
NASA has established that a person cannot survive if the index of a wet bulb is above 35 ° C for six hours. This temperature has been recorded several times in the subtropics of Pakistan and the Persian Gulf. As Future-Sciences points out, most of the Earth’s hot and humid regions have a wet bulb index between 25 and 27 ° C maximum.
South Asia and global warming, the Persian Gulf and some American states uninhabitable for 30 to 50 years?
Within 30 to 50 years, many regions may become uninhabitable due to a wet bulb index above 35 ° C. This could be the case, by 2050, in South Asia, the Persian Gulf (Iran, Oman, Kuwait), countries bordering the Red Sea (Egypt, Saudi Arabia, Sudan, Ethiopia, Somalia, Yemen).
By 2070, eastern China and parts of Brazil could also exceed 35 ° C. This is the same in many American states: Arkansas, Missouri and Iowa.
For its work, NASA relied on instruments installed on the International Space Station (ISS), in particular the AIRS (Atmospheric Infrared Sounder) and the ECOStress (ECOsystem Spaceborne Thermal Radiometer Experiment).
Global warming: 4 things to keep in mind from the IPCC shock report
On Monday October 8, the IPCC published a report on the effects of global warming of 1.5 ° C and its recommendations.
In 2015, the climate conference (COP21) set a goal of not exceeding a temperature rise of 2 ° C. For the IPCC (Intergovernmental Panel on Climate Change), this is too much.
Specialists recommend 1.5 ° C to prevent the effects of global warming on the planet.
Among the various courses of action, the reduction of greenhouse gas (GHG) emissions from fossil fuels (oil, coal, gas, etc.). On the other hand, by 2040, the average temperature on the planet will reach or exceed 1.5 ° C compared to the industrial era.
Reducing greenhouse gases thanks the earth to fight global warming
To achieve a reduction in greenhouse gases that cause global warming, the IPCC is calling on soils, which store three times more carbon than the atmosphere, according to the National Institute of Agronomic Research (INRA).
This new study confirms that we have about 10 years left before global warming reaches 1.5 ° C.

The goal of zero CO2 emissions is possible before 2050 with the absorption of carbon in the earth, says Joël Guiot, one of the authors of the IPCC report and paleoclimatologist at the National Center for Scientific Research (CNRS).
Today, the amount of carbon in the atmosphere is increasing, while the earth may have it in excess through plants that absorb CO2.
Better absorption of GHG emissions requires non-bare lands to limit carbon loss, to stop all deforestation and to replace intensive agriculture with more land-respecting agriculture.
The development of renewable energy

The IPCC recommends a rapid shift from fossil fuels to renewable energy to curb global warming. To achieve a 45% reduction in global GHG emissions by 2030 (compared to 2010). With a target of 70% renewable energies by 2050 for 7% fossil fuels.
As a reminder, France has included a target of 32% green energy by 2030 in the energy transfer law. However, the Climate-Energy Observatory reported a 12.8% decrease in the share of renewable energy in 2016 and an overall increase of 6.7% in greenhouse gas emissions in 2017.
Urban development is a factor in global warming. The IPCC recommends that cities avoid urban sprawl, as urban construction can contribute to rising temperatures. Even when the sun goes down, the buildings will stay warm and the temperature in the cities will not drop, explained Joël Guiot.
There are ancestral solutions; Mediterranean cities, for example, use white stones that reflect sunlight. Unlike cities in the north, which are made of bricks that absorb energy. Urban areas should also create more room for green spaces and waters to lower the temperature and eliminate air conditioning that can increase greenhouse gases.
Fight against global warming to eradicate poverty
The IPCC report raises another important point: limiting global warming to 1.5 ° C can curb the rise of poverty. The first to be affected by climate change are the poorest.
Rising temperatures are gradually drying up the southern regions where fishing and agriculture are the main economic factors. And diseases like malaria grow faster in a mosquito -friendly climate.
Staying below 1.5 ° C costs three to four times more than doing nothing. The reduction of cheap fossil fuel and the development of renewable energy will increase energy costs.
This is not easy for countries like China or India, which have experienced rapid growth. Countries that choose to move towards 1.5 ° C will leave with a green economy in the long term. But it can be difficult in the short term, explained Joël Guiot, one of the report’s authors.
