Coral reefs continue to die until carbon output drops

Scientists have concluded for the last decade that more-acidic seas have been harming coral, making it more difficult for coral reefs to grow or regenerate themselves. Conducting an experiment over the course of 22 days, scientists flooded Australia’s Great Barrier Reef with an antacid. They found that by lowering the water’s acidity, it caused the coral to grow. Research has […]

The research challenges the conclusions of other studies, including the Intergovernmental Panel on Climate Change’s (IPCC) 2013 report, which says that […]

How Native American depopulation impacted ecology

But when it comes to the timing, magnitude, and effects of this Native American depopulation — it depends on who you ask. Many scholars claim that disease struck the native population shortly after their first […]

Ancient fossil forest unearthed in Arctic Norway

UK researchers have unearthed ancient fossil forests, thought to be partly responsible for one of the most dramatic shifts in Earth’s climate in the past 400 million years. The fossil forests, with tree stumps preserved in place, were found in Svalbard, a Norwegian archipelago situated in the Arctic Ocean. They were identified and described by Dr Chris Berry of Cardiff […]
