SEA LEVEL RISE
India witnessing average sea level rise of 1.7mm/year
The government has told the Rajya Sabha that Indian coast have risen by 8.5 cm during the past 50 years. The data shared in the upper house of the Parliament is from 10 major ports across the country. The data, collected at 10 Indian ports, indicates sea levels at Diamond Harbour in West Bengal recorded the highest annual average increase.
Sea-level rise could put 300 million people at risk by 2050
The study estimates that by 2050, without dramatic reductions in greenhouse gas e...
7-fold surge in Indians at risk due to rising sea level
That projection is a seven-fold rise from a previous estimate of 5 million for the country, and the impact is likely to be concentrated in Mumbai, Kolkata, Odisha, coastal Gujarat, as well as Chennai and Kochi, the study shows.
7-fold surge in Indians at risk due to sea level
By 2050, 36 million Indians may be at affected by flooding and inundation due to sea level rise by 2050, according to a new study published this week. That projection is a seven-fold rise from a previous estimate of 5 million, and the impact is concentrated in Mumbai, Kolkata, Odisha, coastal Gujarat, as well as Chennai and Kochi, the study shows.
Sea levels rising faster, Indian cities at high flood risk: IPCC
Four Indian cities are among 45 such coastal port cities globally where even an increase of sea level by 50 cm will lead to flooding.
Cut emissions to avert catastrophic sea-level rise: UN climate report
Days after millions of young people demanded an end to the fossil fuel era at protests around the globe, a new report by a UN-backed panel of experts found that radical action may yet avert some of the worst possible outcomes of global warming.
Humanity must rescue oceans to rescue itself, UN warns
Crumbling ice sheets, rising seas, melting glaciers, ocean dead zones, toxic algae blooms -- a raft of impacts on sea and ice are decimating fish stocks, destroying renewable sources of fresh water, and incubating superstorms that will ravage some megacities every year, according to a landmark assessment approved by the 195-nation Intergovernmental Panel on Climate Change (IPCC).
Underwater glacial melting much faster than predicted: Study
Underwater melting of tidewater glaciers is occurring much faster than previously thought, according to a study which could lead to improved forecasting of climate-driven sea level rise. The study, published in the journal Science, shows that the prevailing theory for melt significantly underestimates melt rates.
How artificial snow can save Antarctica’s crumbling ice sheet
Scientists believe global warming has caused enough melting at the south pole that the giant ice sheet is now on course to disintegrate, which would trigger a global sea-level rise of at least 10 feet over centuries. New research envisaged using 12,000 wind turbines to pump seawater 4,900 feet and freeze it into “snow” to weigh the sheet down from collapsing.
Sea levels along Indian coast rose by 1.3 mm/yr during last 40-50 years: Govt
Ashwini Kumar Choubey said rising sea levels can exacerbate the impacts of coastal hazards such as storm surge.
Greenland may lose 4.5 per cent ice by end of century: Study
Greenland may lose 4.5 per cent of its ice by the end of this century - contributing up to 13 inches of sea level rise - if worldwide greenhouse gas emissions remain on their current trajectory, a study has warned.
Halting biodiversity loss and ecosystems degradation is central to Asia-Pacific region’s growth and well-being
The 2018 report highlights the importance of biodiversity and ecosystem services in the development of the region
Antarctica ice melting increased by 280% in last 16 years, study says
The researchers were able to discern that between 1979 and 1990, Antarctica shed an average of 40 gigatonnes of ice mass annually. From 2009 to 2017, about 252 gigatonnes per year were lost.The rate jumped 280%. The study published researchers conducted the longest-ever assessment of remaining Antarctic ice mass.
