Climate change, not just increasing atmospheric temperatures, has been affecting the Jet Stream. When the Jet Stream travels across from the West to the East over the Northern Hemisphere in normal conditions the weather is not greatly affected, but because of the climate change it has been slowing down and causing massive heat waves and flooding. When the jet stream […]

Coral reefs around the world are experiencing a massive die-off that could be the worst in recorded history, a new study warns. Stoked by climate change and a powerful El Nino, record-high ocean temperatures have triggered the global event, which began last year and is expected to destroy 5 percent of the world’s coral reefs by 2016. The temperature changes […]

Aerosols, tiny solid and liquid particles suspended in the atmosphere, impact the environment by affecting air quality and alter the Earth’s radiative balance by either scattering or absorbing sunlight to varying degrees. What impact does climate change, induced by greenhouse gases (GHGs), have on the aerosol “burden”–the total mass of aerosols in a vertical column of air? Past research done […]

Chikungunya is a serious health threat. Mosquitoes once limited to tropical I regions are spreading north to the U.S., carrying both dengue fever and Chikungunya, a virus that causes fever, chills, headache, and punishing joint pain that can persist for years. Once a relatively obscure illness limited mostly to Africa, Chikungunya (pronounced chicken gunya) has transformed over the past decade […]

Tropical forests account for a third of the total carbon fixed by photosynthesis. Lianas’ increasing abundance may be driven by changing climate, increased disturbance or by more severe seasonal drought. By reducing the ability of tropical forests to accumulate and store carbon released through burning fossil fuels, lianas could cause a positive feedback loop, accelerating climate change. “This study has […]

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 […]

An influential panel of climate scientists has expressed higher confidence than ever that human activity is the main cause of the rise in global temperatures since the 1950s, Reuters.com reports. A leaked draft of an upcoming report of the United Nations’ Intergovernmental Panel on Climate Change, based on a broad analysis of published scientific studies, concludes with 95 percent certainty […]

Despite no exposure to sunlight or fresh air for more than a million years, a lake located half a mile beneath the Antarctic ice sheet sustains an entire ecosystem, scientists have confirmed—raising the prospect that life might exist in similar environments elsewhere in the universe. Researchers had long suspected the existence of tiny life-forms living below the ice pack, and […]

Cold-blooded animals like lizards, insects and fish have a preferred body temperature range at which they hunt, eat, move quickly and reproduce. Fear that a warming climate will constrict this temperature range underlies recent studies that warn of the detrimental effects of climate change on the activity and survival of cold-blooded animals. While not contradicting these warnings, a new paper […]

UK researchers have unearthed ancient fossil forests, thought to be partly responsible for one of the most dramatic shifts in Earth’s climate in the past 400 million years. The fossil forests, with tree stumps preserved in place, were found in Svalbard, a Norwegian archipelago situated in the Arctic Ocean. They were identified and described by Dr Chris Berry of Cardiff […]
