Antarctic ice drives crucial deep-ocean currents that help regulate Earth’s climate. But the system is slowing down. Part of Earth’s deep-ocean conveyor belt is slowing, and melting ice is to blame, according to new research. When the sea freezes around Antarctica’s fringes in winter, the ice expels salt into the water below. Trillions
In the past few weeks, climate records have shattered across the globe – 4 July was the hottest global average day on record, breaking the record set the previous day. Average sea surface temperatures have been the highest ever recorded and Antarctic sea ice extent the lowest on record. Also on 4 July,
A new genealogy based on similarities in the computer codes of different climate models could improve studies that combine projections from multiple models. Climate models are sophisticated numerical tools used to estimate and explore what Earth’s climate was like in the past, how it behaves now, and how it will change in the
The current head of Argentina’s National Meteorological Service (SMN, for its acronym in Spanish) has been appointed the new Secretary-General of the World Meteorological Organization. For the first time in its 150-year history, the top agency for weather, climate and water will be run by a woman. The professional career of Celeste Saulo
A pair of studies demonstrate the uncertainty over when the Arctic will become seasonally sea ice free. Every September since 1979, the U.S. government has measured the extent of sea ice in the Arctic. And the picture is not a pretty one—more than 2 million square kilometers have been lost in that time,
Deciphering Climate Shifts Emerging from an eminent British academic environment, I present a learned view on the daunting subject of climatic shift. The Earth’s meteorological character has been eternally versatile, oscillating naturally across epochs. Yet, the accelerated fluctuations we’re observing presently are largely the consequence of human pursuits, with extensive repercussions on global
Social media trolls have become a dangerous and often unavoidable part of our online lives. They bully, lie, and try to confuse social media users, and some are even paid to do so. While they may seem like a mere annoyance, they have the ability to influence opinion on some of the world’s
Climate transformation poses a relentless global menace, and the urgency to unearth solutions capable of counteracting, if not entirely reversing, the repercussions of our historical and current behaviour, is skyrocketing. The instrumental impact of technological innovation in this crusade cannot be overemphasised. We venture to delve into five potentially revolutionary technologies that could
A new book from water expert Peter Gleick urges a rethinking of how we use, manage and value one of our most important resources. It’s time for a reckoning … with water. It’s central to our bodies, the planet, our modern lives, and yet we continue to use it unwisely, to pollute rivers,
Only a third of U.S. consumers consider “climate-friendliness” when shopping at the grocery store, a new survey finds. Environmental sustainability lags far behind taste, price, healthfulness and convenience for the 11th year in a row, according to this year’s consumer research from the International Food Information Council (IFIC). The number of self-reported vegans
