Milan’s marble facades and narrow, stone-paved streets look elegant and timeless. But all of that stone emits heat and does nothing to absorb rain, and temperatures and flooding in the posh Italian city are only predicted to increase in the coming decades. In Jakarta, black floodwaters already rush into homes every winter along the Indonesian … Read more
he world’s oceans are home to microscopic organisms invisible to the human eye. The tiny creatures, known as “prokaryotes”, comprise 30% of life in the world’s oceans. These organisms play an important role in keeping the oceans in balance. But new research by myself and colleagues shows this balance is at risk. We found prokaryotes … Read more
Researchers have synthesized highly durable solar cells made from perovskite — a common crystal structure (in its natural form a calcium titanium oxide mineral) — in a breakthrough that could revolutionize the solar industry. Solar power is the fastest-growing energy technology and plays a key role in cutting greenhouse gas emissions. Solar power converts sunlight … Read more
Scientists believe Earth may have briefly lost protection from the sun around two million years ago, left to endure the extreme environment of interstellar space as the solar system passed through a dense cloud of gas and dust between stars. At that time, early human ancestors shared our planet with prehistoric animals like mastodons and … Read more
So-called “zombie fires” in the peatlands of Alaska, Canada and Siberia disappear from the Earth’s surface and smoulder underground during the winter before coming back to life the following spring. These fires puzzle scientists because they appear in early May, way ahead of the usual fire season in the far north, and can reignite for … Read more
The “gateway to the underworld,” a huge crater in Siberia’s permafrost, is growing by 35 million cubic feet (1 million cubic meters) every year as the frozen ground melts, according to a new study. The crater, officially known as the Batagay (also spelled Batagaika) crater or megaslump, features a rounded cliff face that was first … Read more
Mars’ gravitational pull on Earth may be influencing the climate on our planet, new research hints. Geological evidence tracing back more than 65 million years and taken from hundreds of sites across the world suggests that deep-sea currents have repeatedly gone through periods of being either stronger or weaker. This happens every 2.4 million years … Read more
Water vapor in the stratosphere forms a sponge-like barrier that prevents heat radiating from Earth from escaping out into space. Now, scientists are exploring the plausibility of dehydrating this layer of the atmosphere to cool our warming planet. The stratosphere extends between 7.5 and 31 miles (12 and 50 kilometers) above Earth’s surface and sits … Read more
Earth’s present-day climate change is human-induced, but the gravitational tugs of other planets can also cause long-term climatic patterns by slightly changing our planet’s orbit. Now, research suggests that massive passing stars can alter Earth’s path, too — and that these cosmic tugs may limit researchers’ ability to study the links between past changes in … Read more
A new study has claimed that we may breach the 2 degrees Celsius (3.6 degrees Fahrenheit) climate change increase threshold by the late 2020s — almost two decades earlier than current projections. The study, published Feb. 5 in the journal Nature Climate Change, claims global surface temperatures had increased by 1.7 C (3 F) above … Read more
