Herds of wooly mammoths once shook the earth beneath their feet, sending humans scurrying across the landscape of prehistoric Ohio. But then something much larger shook the Earth itself, and at that point these mega mammals’ days were numbered. Something – global-scale combustion caused by a comet scraping our planet’s atmosphere or a meteorite slamming [...]

Researchers show that high ancient shorelines do not necessarily reflect ice sheet collapse millions of years ago For decades, scientists have used ancient shorelines to predict the stability of today’s largest ice sheets in Greenland and Antarctica. Markings of a high shoreline from three million years ago, for example – when Earth was going through [...]

 A melt of ice on Greenland and Antarctica is likely to be less severe than expected this century, limiting sea level rise to a maximum of 69 cm (27 inches), an international study said on Tuesday. Even so, such a rise could dramatically change coastal environments in the lifetimes of people born today with ever more severe storm surges and erosion, [...]

Given our lack of knowledge, we should avoid jumping to conclusions based on one piece of data. Last week we got some bad news from a Hawaiian volcano. Not an eruption, but an emissions measurement that has far greater global significance. At a facility on Mauna Loa, instruments measured carbon dioxide levels at 400 parts [...]

Climate change is melting Greenland’s ice sheet at a rapid pace. But now, new research has shown that the ice may not melt as quickly in the future as we once thought. Computer models have revealed that the shape of the ground beneath the ice sheet could drastically impact how fast melting occurs. Over the [...]

EXPERTS on a panel responsible for handing out $200 million in government research funds have awarded so many grants to entities linked to each other or colleagues that independent MP Rob Oakeshott has referred them to the Auditor-General. An analysis by The Australian reveals the Department of Agriculture, Fisheries and Forestry’s advisory panel chaired by [...]

David Holland Takes On The IPCC’s Lack Of Transparency Can the Internet help climate scientists? Not everyone thinks so. “The Internet is a double-edged sword,” Met Office scientist Peter Stott told a London courtroom last week. “There’s a whole cacophony of voices on blogs, people with different opinions and people very motivated to dig around. [...]

Most people have never heard of the Anthropocene era and with good reason—it is not an officially recognized geologic time period. It is the invention of a small group of scientific busy bodies who evidently have nothing better to do than try to effect a change in the official timeline of Earth’s past. The International [...]
