Heatwaves that used to arrive once every 20 years or so could become annual events by 2075 across almost two-thirds of the planet’s land surface – if humans go on burning ever more fossil fuels and releasing ever more greenhouse gases. Claudia Tebaldi, visiting scientist at the US National Center for Atmospheric Research, and Michael Wehner, senior staff scientist at […]

Scientists have recorded that the temperature of the oceans has been on the rise. The temperatures have been rising at a rate of 40% on average over what they previously predicted over the past five years. The year 2018 was warmer than the previous year and it’s still getting warmer. Heating of the ocean plays a big role in climate […]

Soil frost is a nearly universal process in the Arctic. In a recent dissertation by doctoral student Marina Becher at Umeå University, it is shown that the frequency and extent of Arctic soil frost is important for the release of the greenhouse gas carbon dioxide from arctic soil. Soil in the Arctic has for thousands of years gathered large quantities […]

The world’s leading economies are heading in the right direction on tackling climate change, but some still have a long way to go to make their undertakings politically credible, according to a UK research center. With the Paris Agreement barely two months old, the world now moves from talk to action − or at least that’s the theory. The Agreement […]

At least half of the world’s killer whales will become extinct because of toxic waste in the oceans within the next century according to researchers. Some areas despite efforts to control the pollutants of polychlorinated biphenyls (PCBs) still remain at high levels. Research scientists from the Zoological Society of London (ZSL) are saying that if we don’t bring down the […]

Climate change may have helped to alter the course of history. A period of extreme and unprecedented cooling in the northern hemisphere 1,500 years ago may have reduced the eastern Roman empire, set the stage for a famine and a devastating pandemic that killed millions, and favored the rise of the Islamic forces that created the Arab empire. The so-called Little […]

It seemed like a good idea at the time. In 1972, Broward County, Fla., organized more than 100 boats to dump an estimated 700,000 tires into the Atlantic Ocean in hopes of sparking the growth of an artificial reef. Ultimately corals never grew on the bundles of tires, and over time the bundles became loose, causing damage to nearby natural […]

Until recently, Pakistan has not used the bulk of its coal reserves – some of the largest in the world – for power generation. Within the past year the government in Islamabad has signed a number of financial and technological agreements with China aimed at exploiting massive coal reserves at the Tharparkar mine in Sindh province, in the south of the […]

Climate change appears to be affecting the jet stream, altering the weather patterns over the U.S. so that regions can get “stuck” in extreme weather for weeks, a new study has found. The jet stream is the fast-moving, high-altitude air current that shuttles weather from west to east over North America and Europe. But the pronounced warming of the Arctic—where […]
