Crested and rockhopper penguins are threatened by climate change – but this time the penguins could be at risk because they cannot change their own ways. Evolution has left them with a rigid parenting strategy, probably well adapted for climate conditions so far. But as temperatures rise, conditions change and food supplies become precarious, the inflexible roles of male and female […]

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 […]

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 […]

What happened A United Nations panel of the world’s leading environmental scientists issued its most dire warnings on the dangers posed by climate change, saying global warming is already affecting every continent and threatens to devastate food supplies, cause mass extinctions of plants and animals, worsen droughts, and raise the risk of wars over resources. The longer society holds off […]

Climatologists have started to drill into the oldest ice core in Antarctica to find some air that may have been there around 1 million to 900,000 years ago. The teams are from Australia, China, and Europe in a friendly type competition to find samples of air that is about 1.5 million years old. They would like to find out what […]

Simple statement: 13 of the 15 warmest years ever recorded have occurred within the first 15 years of this century. Complicated question: what is the probability that this happened purely by chance? The latest calculated answer: it could be one in 5000, or it could be as unlikely as one in 170,000, or it could be somewhere in between. Conclusion: […]

Tropical groundwater may prove to be a climate-resilient source of freshwater in the tropics as intense rainfall favours the replenishment of these resources, according to a new study published in Environmental Research Letters. As climate observations show that global warming leads to fewer but more intense rainfalls, a clearer understanding of how these sources are replenished is crucial for developing […]

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 […]

The monster forest fires rampaging across the Western states may soon be the norm, thanks to climate change. New research indicates that as rainfall diminishes and vegetation dries out on a warmer planet, the West is headed into a more fire-prone future,” wildfire specialist Max Moritz tells the Los Angeles Times. After studying satellite imaging of fires and data from […]

The open deliberation about environmental change is done – on the grounds that it has been completely demonstrated NOT to exist, one of the world’s best known environmental change doubter has asserted. John Coleman, who helped to establish the Weather Channel, stunned scholastic’s by demanding the hypothesis of man-rolled out atmosphere improvement was no more deductively dependable. Rather, what ‘little […]
