According to the 2018 global report of the International Energy Agency, demand for air conditioning will triple by 2050, which will increase electricity consumption and carbon dioxide emissions and thereby accelerate the rate of global warming.
It is forecast that within 30 years, the number of air-conditioned buildings may increase from 1.6 to 5.6 billion, while the one billion tonne annual carbon dioxide emission of the sector will at least double.
In the United States and Japan, 90 percent of households have air conditioning, and even China has reached 60 percent. According to a new energy report from Bloomberg, demand has begun to increase in the poorest regions where warming has the strongest impact. This claim is confirmed by a study published in Nature, which states that in India, for instance, the number of presumably cheap and not particularly energy efficient air conditioning units producing cool air could increase from thirty million to as much as a billion by 2050.
Data indicate that cities are warming faster than the global average. Urban climate researchers have found that the drastic warming of urban areas is caused by extra anthropogenic heat, 80 to 90 percent of which is produced by the air conditioning devices operating during the summer in residential and office areas.
According to researchers at the Lawrence Berkeley National Laboratory of the University of California, there is a way out of the vicious circle: climate-friendly development of air conditioning technology could reduce the negative impact by 20–25 percent. They believe that improving the efficiency of air conditioners could reduce global greenhouse gas emissions by about 89.7 gigatonnes.
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.
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.
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 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.
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.
More than a quarter of all mammals are threatened with extinction.
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 French falconer Jacques-Olivier Travers has surveyed the glaciers of the Alps using a camera attached to a white-tailed eagle.
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.
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.
