A research paper published in Nature Climate Change predicts widespread death of needleleaf evergreen trees (NET) within the Southwest United States by the year 2100 under projected global warming scenarios. The research team that conducted the study, which includes University of Delaware’s Sara Rauscher, considered both field results and a range of validated regional predictions and global simulation models of […]

A floating island made out of plastic the size of Hawaii made entirely from plastic bottles could become the hottest postcode on earth, and is part of an incredible environmental vision for the future. CGI images show how a team of Dutch scientists plan to take 44 million kilos of plastic waste currently bobbing around in the Pacific Ocean and […]

Climate change is killing off Bees In India. A lethal combination of climate change and human interference is helping to wipe out colonies of the giant honeybees on which many plants and trees in India depend for their survival. The precise cause of colony collapse disorder (CCD) is not known, but researchers say that the loss of the bees will […]

The year 1934 was a very hot year in the United States, ranking fourth behind 2012, 2006, and 1998. However, global warming takes into account temperatures over the entire planet. The U.S.’s land area accounts for only 2% of the earth’s total surface area. Despite the U.S. heat in 1934, the year was not so hot over the rest of […]

Today’s solar cell technology has its roots in the early days of America’s space program, when in 1958, NASA launched the solar-powered Vanguard I satellite. Solar power technology has become more efficient. But the cost is still two to four times more than other energy sources. 10. The Netherlands Most solar energy in The Netherlands comes from solar cells […]

Geologists are convinced that humans have left a mark upon the planet that will detectable millions of years from now. Long after human civilization has perished, there could be a stratum of fossilized rock and a geological time zone that says: “We were here.” So there is a case for calling the present epoch “the Anthropocene” − probably dating from […]
