Climate Change Helped Kill the Wooly Mammoth

29 Jul

Wooly Mammoth

According to a new study published in Science, abrupt climate change was part of the one-two punch that killed off most of the Earth’s mammalian megafauna, such as the wooly mammoth and wooly rhinoceros. A series of rapid warming events, called interstadials, happened between 60,000 and 12,000 years ago, and coincided with extinction events even […]

New Data on Polar Bears Reinforces Fears for their Survival

Polar Bear

A new study published recently in the journal Science has some good and bad news about polar bears. The study is based on research completed from 2008 to 2010, in which over two-dozen polar bears were captured and tagged with temperature loggers, and then tracked. First the bad news. As most readers should be aware, […]

Climate Change

According to a recent report lead by professors at the University of Cambridge, we need to take global climate change as seriously as we once took the threat of nuclear war. The report, which included experts from the United Kingdom, the United States, China, and India, put forth a number of significant threats to humans, […]

Bearded Dragons Change Sex in Extreme Temperatures

Bearded Dragon

From melting ice caps to fish migrating to find cooler water, climate change has a great deal more impact on the world than just raising temperatures. Researchers at the University of Canberra in Australia have discovered another way climate change impacts the world: it is changing the sex of bearded dragons. For some time now, […]

Evolutionary Biologist Predicts Earth-like Evolutionary Trends on Other Planets

14 Jul

Earthlike Planet

In his new book, The Runes of Evolution, Professor Simon Conway Morris makes the argument that evolution follows predictable paths, which includes the eventual development of intelligence, and as such, there should be other intelligent life forms in the galaxy. Conway Morris is a leading evolutionary biologist, but he supports the idea of convergent evolution, […]

Astronomers Confirm the Existence of Five Supermassive Black Holes

Black hole

According to astronomers at Durham University in the United Kingdom, there may be millions of supermassive black holes in the universe. This estimate is based on their having finally confirmed the existence of five supermassive black holes that were clouded from view by gas and dust. The international team used NASA’s Nuclear Spectroscopic Telescope Array […]

Warmer Northern Seas Means Colder Western Europe

11 Jul


According to new research by scientists in Canada, the United Kingdom, Norway, and the United States, retreating sea ice in the Iceland and Greenland seas will lead to colder weather in Europe. Warm weather in Western Europe is dependent upon a cold North Atlantic, which helps to perpetuate the Gulf Stream that helps keep Europe […]

Combined Effect of Carbon Emissions Place the Worlds Oceans in Extreme Danger

10 Jul

Carbon Emissions

The world’s oceans are under constant threat from anthropocentric (human caused) carbon emissions. Numerous studies in recent years have shown that the oceans are becoming increasingly acidic, that water temperatures are rising, and that ice in the polar regions is melting. Most such studies point to carbon emissions and, by association, humans as the culprits. […]

Some Californian Wildflowers Face Extinction

2 Jul


California can’t win when it comes to water. This year’s drought and water rationing is old news, but a study by researchers from UC Davis, published in Proceedings of the National Academy of Sciences, has brought another problem to light: California’s wildflowers are at risk of severely reduced biodiversity. While many of California’s water problems […]
