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 …
Bangladesh is taking part in a climate change expedition to Antarctica to explore and highlight the pace and alarming impacts of greenhouse pollution unfolding even in the world's most remote frozen continent. Al Gore, a Nobel Peace Prize winner and former US vice president, is leading the 116-member expedition, “A …
The melting down of the Himalayan glaciers due to climate change may be solving the current water crisis, but can also have a devastating effect on animal and human lives in the long run, environmentalist and polar explorer Robert Swan has said. “What scares me is that people think that …
Developed for troops serving on glaciers high in the Himalayas, the non-flushing “bio-digester” toilet made by India’s top defence research body is now being offered to companies and poorer states. It is one of 200 technologies produced by the Defence Research and Development Organisation (DRDO) identified as for-sale via the …
The root of the mysterious range of Antarctic mountains completely hidden under the continent’s massive ice sheet may be over 200 million years old, dating back to the dinosaur age, scientists have claimed. Researchers, on a project to understand the Gamburtsev Subglacial Mountains in east Antarctica better, said the mountains …
Panaji: Nearly 28 years after it set up the first permanent research station in the South Polar region, India is all set to commission and occupy a third such station in Antarctica by March next year. After the station named 'Bharti' becomes operational, India will join the league of select …
Chemical ozone destruction occurs over both polar regions in local winter–spring. In the Antarctic, essentially complete removal of lower-stratospheric ozone currently results in an ozone hole every year, whereas in the Arctic, ozone loss is highly variable and has until now been much more limited. Here we demonstrate that chemical …
Washington: The first significant ozone hole above the Antarctic is now as big as North America, scientists have claimed. Spanning about 25 million square kilometers, the ozone hole over the South Pole reached its maximum annual size on September 14, becoming the fifth largest on record, they said. The largest …
An ambitious mission to search for life that has been buried beneath 3km of ice in an Antarctic lake for hundreds of thousands of years begins in earnest this week. A team of British scientists and engineers will start transporting the 70 tonnes of drilling equipment needed to penetrate the …
An ancient lake hidden deep beneath West Antarctica's Ice Sheet may reveal vital clues about climate change and future sea level rises, and uncover new forms of life, according to a group of UK engineers and scientist. This month a British engineering team will travel to one of the most …
Paris: An ozone hole five times the size of California opened over the Arctic this spring, matching ozone loss over Antarctica for the first time on record, scientists said on Sunday. Formed by a deep chill over the North Pole, the unprecedented hole at one point shifted over eastern Europe, …
An ozone hole five times the size of California opened over the Arctic this spring, matching ozone loss over Antarctica for the first time on record, scientists said on Sunday. Formed by a deep chill over the North Pole, the unprecedented hole at one point shifted over eastern Europe, Russia …
This work aims to identify the geographic distribution of photovoltaic (PV) energy potential considering the effect of temperature on PV system performance. A simple framework is developed that uses the JIS C 8907 Japanese industrial standard to evaluate the effects of irradiation and temperature on PV potential. The global distributions …
We review the sea-level and energy budgets together from 1961, using recent and updated estimates of all terms. From 1972 to 2008, the observed sea-level rise (1.8 ± 0.2 mm yr−1 from tide gauges alone and 2.1 ± .2 mm yr−1 from a combination of tide gauges and altimeter observations) …
A new map of Antarctica illustrates for the first time how ice moves across the continent. The map’s creators believe it may be a crucial tool in helping researchers understand how a warming climate is changing the continent. The creation of the digital map was supported by NASA and combines …
Images of the sea floor in Pine Island Bay, West Antarctica, reveal impressive evidence that a massive ice-shelf break-up occurred before about 12,000 years ago, and point to a tidal influence on sea-floor features produced during deglaciation.
Methane and ethane are the most abundant hydrocarbons in the atmosphere and they affect both atmospheric chemistry and climate. Both gases are emitted from fossil fuels and biomass burning, whereas methane (CH4) alone has large sources from wetlands, agriculture, landfills and waste water. Here we use measurements in firn (perennial …
The Indian Ocean bed promises to be the next frontier for earth system scientists in the country. India, who has been granted mining rights for 75,000 sq km of the ocean bed in the central Indian Ocean by the International Seabed Authority, plans to expedite its activities in the region. …
Two decades after setting foot on the land of blizzards, India is all set to rebuild Maitri, the first permanent station on Antarctica. The research station would be totally redone with a view to making it eco-friendly and independent of fossil fuels. Though use of petroleum products cannot be totally …
