Researchers are trying to determine why a once green Sahara turned into a desert. Today there is enough evidence to show that the Sahara Desert had once a grassland ecosystem and was a much wetter place than it is today. We do know that Sahara...

Scientists are trying to unlock the secrets of Sahara and understand why and when this region that had once a grassland ecosystem turned into a desert. An ancient peat bog in Romania may shed some new light on this long-standing mystery. Using carbon dating and...

Perhaps now is a good time to wake up and change our environmental policy. Scientists warn that 74% of the world’s population will be exposed to deadly heatwaves by 2100 if carbon gas emissions continue to rise at current rates. Even if emissions are aggressively...

– For some unknown reason millions of bizarre, luminous jelly-like creatures have suddenly appeared off the Pacific Northwest and Alaska. Scientists are puzzled and currently no-one knows why these creatures have showed up. Water along the western coast of the USA has been extremely warm...

Noctilucent or “night-shining” clouds (NLCs) are mysterious, electric glowing clouds that are beautiful to watch. They were first seen 1885 about two years after the powerful eruption of Krakatoa hurled plumes of volcanic ash as much as 80 km high in Earth’s atmosphere. These eye-catching...

The effects of climate change are most apparent in the Earth’s north and south poles, which one of the reasons why scientists monitor changes on Antarctica very closely. New satellite images show a giant iceberg will split from Antarctica anytime now. The iceberg is estimated...

As the climate change debate continues, many keep asking – who is responsible for climate-warming trends over the past century? Should we blame humans, Mother Nature or a combination of both? The vast majority of climate scientists seems to agree that human activities are changing...

– Researchers have long argued what caused the global mass extinction 30,000 years ago. According to a new study the reason was climate change. During the last Ice Age, Australia, Tasmania and New Guinea formed a single landmass. It was a strange and often hostile...

– The Siberian craters are small in comparison to these giant methane “monsters” that have been discovered on the Arctic Sea floor. Methane, a potent greenhouse gas is still leaking in large amounts from the enormous craters that formed about 12,000 years ago. “The crater...

– A group of historians and climate scientists challenge assumptions that widespread environmental pollution began with the Industrial Revolution in the 1700s and 1800s. By examining ice from the time when the Black Death struck Europe, researchers found evidence that Europeans have polluted the air...
