This is the 33rd issuance of the annual assessment now known as State of the Climate, published in the Bulletin since 1996. As a supplement to the Bulletin, its foremost function is to document the status and trajectory of many components of the climate system. However, as a series, the …
Part of East Antarctica is more vulnerable than expected to a thaw that could trigger an unstoppable slide of ice into the ocean and raise world sea levels for thousands of years, a study showed on Sunday. The Wilkes Basin in East Antarctica, stretching more than 1,000 km (600 miles) …
More ice means fewer elephant seal pups, according to Australian scientists studying breeding colonies on Macquarie Island near Antarctica and atmospheric changes in the region that have affected the feeding grounds. "When there's more sea ice the population is likely to go down and in years when there's less sea …
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 …
The steam and heat from volcanoes allowed species of plants and animals to survive past ice ages, a study showed Tuesday, offering help for scientists dealing with climate change. An international team of researchers said their analysis helped explain a long-running mystery about how some species thrived in areas covered …
The southern hemisphere westerly winds have been strengthening and shifting poleward since the 1950s. This wind trend is projected to persist under continued anthropogenic forcing, but the impact of the changing winds on Antarctic coastal heat distribution remains poorly understood. Here we show that a poleward wind shift at the …
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 …
Closure of ISROs activities at research station at Antarctica - Question raised in Rajya Sabha, 10/02/2014. Minister For Ministry Of Science And Technology And Ministry Of Earth Sciences, S. Jaipal Reddy has stated in the Parliament that ISRO’s activities at Bharti came to a temporary halt due to the shut-down …
A number of floating ice shelves in Antarctica are at risk of disappearing entirely in the next 200 years, as global warming reduces their snow cover, a new study has warned. Their collapse would enhance the discharge of ice into the oceans and increase the rate at which sea-level rises, …
Pine Island Glacier, the largest single contributor to sea-level rise in Antarctica, has started shrinking, say scientists. The work, published in Nature Climate Change, shows the glacier's retreat may have begun an irreversible process that could see the amount of water it is adding to the ocean increase five-fold. 'At …
The world's largest tropical desert, the Sahara, has suffered a catastrophic collapse of its wildlife populations, a new study has warned. The study assessed 14 desert species and found that a shocking half of those are regionally extinct or confined to one percent or less of their historical range. Led …
We assess climate impacts of global warming using ongoing observations and paleoclimate data. We use Earth’s measured energy imbalance, paleoclimate data, and simple representations of the global carbon cycle and temperature to define emission reductions needed to stabilize climate and avoid potentially disastrous impacts on today’s young people, future generations, …
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 …
Scientists have identified regions in Antarctica that could store information about Earth’s climate and greenhouse gases dating back to 1.5 million years, twice as old as ice core drilled to date. By studying the past climate, scientists can understand better how temperature responds to changes in greenhouse-gas concentrations in the …
A new scientific report shows that by moving rapidly to reduce pollutants such as methane and black carbon, could slow warming in critical snow and ice-covered regions while benefitting human welfare. Continued melting in snow and ice-covered regions will rise sea levels further, threaten water resources, and release more carbon …
Failure to protect Antarctic waters long-term could leave it vulnerable to oil drilling and fishing within 15 years Talks to create the world’s two largest marine reserves in the Antarctic could be undermined by a last-ditch push for a “sunset clause” that would allow protections from fishing and oil drilling …
"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 …
The opening in the earth's stratospheric ozone layer over Antarctica is closing slowly and should recover completely in the later half of this century, though its effect on global climate change is still uncertain. The Montreal Protocol, which effectively banned chlorofluorocarbons (CFCs), had helped reduce the size of the hole …
Analysis of an Antarctic ice core has revealed that warming in the frozen continent began about 22,000 years ago, a few thousand years earlier than suggested by earlier records. The new research shows that Antarctic warming began at least two, and perhaps four, millennia earlier than had been previously believed. …
