Climate-exodus expected in the Middle East and North Africa
Part of the Middle East and North Africa may become uninhabitable due to climate change
When myth meets reality: fabled beasts and real-life creatures
Fantastic creatures have fascinated humans for thousands of years. When a new skeleton of the extinct horned mammal Elasmotherium sibiricumwas discovered recently, its common name –the “Siberian Unicorn” – quickly resurfaced. But this “unicorn” was very different to the creature of Western mythology.
DNA proves mammoths mated beyond species boundaries
Several species of mammoth are thought to have roamed across the North American continent. A new study in the open-access journal Frontiers in Ecology and Evolution, provides DNA evidence to show that these mammoths, which should only mate within their species boundaries, were in fact likely to be interbreeding.
Volcanoes tied to shifts in Earth’s climate over millions of years
A new study in the April 22 edition of Sciencereveals that volcanic activity associated with the plate-tectonic movement of continents may be responsible for climatic shifts from hot to cold over tens and hundreds of millions of years throughout much of Earth's history.
Accounting for volcanoes using tools of economics
When Mount Tambora erupted in 1815, it spewed dust and sulfate aerosols into the stratosphere with a force more powerful than any eruption since.
Ice Age Antarctic Ocean gives clue to ‘missing’ atmospheric carbon dioxide
Climate is not constant on Earth. Consider ice ages coming and going as an example. Parallel to ice age cycles, atmospheric carbon dioxide reduces during glacial periods and increases during warmer times, although modern fossil fuel-related carbon dioxide emission broke this natural cyclicity. With the proper proxy measurements, scientists can look into these past cycles to determine how exactly climate systems were naturally governed.
