Last January, a study in Nature Climate Change showed the world's glaciers are the smallest they've been in human history, revealing radiocarbon material that hasn't been exposed for 40,000 years. Now, new research published in Nature quantifies how much the world's lost glaciers have contributed to rising sea levels. From …
Heavy rains from the Amazon to Australia have curbed sea level rise so far this century by shifting water from the oceans to land, according to a study that rejects theories that the slowdown is tied to a pause in global warming. Sea level rise has been one of the …
Global warming will disrupt food supplies, slow world economic growth and may already be causing irreversible damage to nature, according to a UN report due this week that will put pressure on governments to act. A 29-page draft by the Intergovernmental Panel on Climate Change will also outline many ways …
The last edge of the Greenland ice sheet that had resisted global warming has now become unstable, adding billions of tonnes of meltwater to rising seas, scientists say. In a study published in the journal Nature Climate Change, they say a surge in temperature from 2003 has eased the brakes …
Sea levels are set to rise perceptibly as the last remaining stable bit of the Greenland ice sheet has turned unstable, a new study has found. The findings of the study, which could lead to higher estimates of expected sea level rise in the future, appears in the latest edition …
The Greenland ice sheet has been one of the largest contributors to global sea-level rise over the past 20 years, accounting for 0.5 mm yr−1 of a total of 3.2 mm yr−1. A significant portion of this contribution is associated with the speed-up of an increased number of glaciers in …
Daily June-July melt fraction variations over the Greenland ice sheet (GIS) derived from the Moderate Resolution Imaging Spectroradiometer (MODIS) (2000–2013) are associated with atmospheric blocking forming an omega-shape ridge over the GIS at 500 hPa height. Blocking activity with a range of time scales, from synoptic waves breaking poleward ( …
Some of the world's most recognizable and important landmarks such as the Statue of Liberty and Sydney Opera House could be lost to rising sea-levels if current global warming trends are maintained over the next two millennia, a new study has warned. The study calculated the temperature increases at which …
At the Boatkhali Kadambini Pre-primary School on Sagar Island in the Sunderbans, classes stop for five-six days each, twice a month, during June to August. Sea water invades the classrooms to a height of one-and-a-half feet, rendering teaching impossible. "It recedes after two-three hours, but it happens twice a day …
The year 2013 is currently on course to be among the top ten warmest years since modern records began in 1850, according to the World Meteorological Organization. The first nine months, January to September, tied with 2003 as the seventh warmest such period on record, with a global land and …
Greenland's parliament voted on Thursday to end a decades-long prohibition on mining for radioactive materials like uranium, further opening up the country to investors from Australia to China eager to tap its vast mineral resources. The move will not only allow the mining of uranium deposits, but also of rare …
A landmark report from the world's top climate scientists this week is likely to say with heightened certainty that humans are behind the planet's rising temperatures, and that surface temperatures are not the only indicators of climate change. Senior scientist Kevin Trenberth of the National Center for Atmospheric Research in …
"Climate Change 2013: The Physical Science Basis" is the contribution of Working Group I to the Fifth Assessment Report of the Intergovernmental Panel on Climate Change. This comprehensive assessment of the physical aspects of climate change puts a focus on those elements that are relevant to understand past, document current, …
New research shows traditional IPCC models could be underestimating global warming due to feedbacks As the world awaits the Intergovernmental Panel on Climate Change's (IPCC) latest verdict on the state of the climate, new research out this year finds that climate change could have double the impact previously thought. The …
Some parts of nature and human society are more vulnerable than expected to climate change, according to a draft of a U.N. report that adds a new purple color to a key diagram to show worsening risks beyond the red used so far. It says "unique and threatened systems" like …
The world's most sparsely populated country could be covered by swathes of forests instead of barren ice sheet, experts say Climate change could bring about the greening of Greenland by the end of the century, scientists predict. Today only four indigenous tree species grow on the island, confined to small …
LONDON: Global warming five million years ago may have caused parts of Antarctica's large ice sheets to melt and sea levels to rise by approximately 20 metres, a new study has claimed. The researchers, from Imperial College London, and their academic partners studied mud samples to learn about ancient melting …
A satellite has detected that 300 billion tonnes of ice is being lost every year from the Antarctic and Greenland glaciers, dramatically increasing sea levels around the world. The satellite that detected the melting is Gravity Recovery and Climate Experiment (GRACE). British scientists have been using it since 2002 to …
Each degree celsius rise in global temperatures is likely to raise world's sea levels by more than 2 metres within the next 2,000 years, a new study has warned. While thermal expansion of the ocean and melting mountain glaciers are the most important factors causing sea-level change today, the Greenland …
A proposal to ban the international trade in polar bear parts was rejected Thursday at a major international conference on wildlife trade, highlighting the difficulties of reaching a global consensus on protecting many kinds of endangered wildlife. The decision on whether to upgrade the protective status of polar bears was …
As the Arctic ice melts it will raise the sea level. But as it does it removes the enormous weight of the ice and the land will rise too in places, Sophisticated computer modelling has shown how sea-level rise over the coming century could affect some regions far more than …
