Nature World: Patagonia in South America was once the home of Ice Age giants, like huge sloths, bears and saber-toothed cats. Suddenly, they all died at exactly the same time--around 12,300 years ago. A new study published in the journal Science Advances revealed that the species were killed off as a result of human activities and rapid climate change. Molecular biologist Alan Cooper of the University of Adelaide said his team discovered that human hunting drove a swift blow to the populations of these Ice...
Changing Winter Climate Causing Permafrost Below Shallow Arctic Lakes to Thaw

Nature World: A new study revealed that warmer winters and increasing snowfalls due to climate change is causing the permafrost below the shallow arctic lake. According to the study published in Geophysical Research Letters, changing winter climates over the last 30 years have limited the growth of seasonal sea ice, leading to warming of lakebed temperature of Arctic lakes less than 1 meter deep by 2.4 degree Celsius. This makes the annual lakebed temperature to be above the freezing point. This rate of...

Climate change 'the key to megafauna extinction'

Cosmos: Bears the size of cars and savage sabre-toothed cats that ruled the plains of ice age Patagonia were no match for a fatal combination of humans and climate change that wiped them out about 12,300 years ago, according to a new study. But contrary to previous research, humans alone did not cause their downfall. The fossil record shows humans had been at Monte Verde, on the edge of Patagonia, from about 14,600 years ago. That means the South American megafauna had coexisted with humans for up to...

New Climate Change and Global Warming Records Unprecedented

Business Times: Climate scientists are stunned at the latest findings that suggest the previous month May was the 13th month in a row to break previously held temperature records. Apart from the soaring heat recorded in February and March, alarm bells are ringing continuously in the form of extreme weather events, ranging from vanishing Arctic sea ice, droughts in India, the vast bleaching of the Great Barrier Reef and flash floods in the UK and in Paris. "It is in my view highly unlikely that we would be...
