Chennai, Kolkata, in India, at particular risk due to sea level rise

The Hindu  

Sea level rise this century may disproportionately affect certain Asian megacities as well as western tropical Pacific islands and the western Indian Ocean, according to a new research. The study showed that internal climate variability could increase sea level rise in some locations by 20-30% more than what would result from climate change alone, exponentially increasing extreme flooding events, it said. Internal climate variability will also increase sea level rise along the west coasts of the United States and Australia, it said. "The internal climate variability can greatly reinforce or suppress the sea level rise caused by climate change," said NCAR scientist Aixue Hu, who co-authored the paper. "In a worst-case scenario, the combined effect of climate change and internal climate variability could result in local sea levels rising by more than 50% of what is due to climate change alone, thus posing significant risks of more severe flooding to coastal megacities and threatening millions of people," said Hu.

Warming of Indian Ocean to accelerate: IITM study

The Hindu  

From 1950-2020, the Indian Ocean had become warmer by 1.2°C and climate models expect it to heat up a further 1.7°C–3.8°C from 2020–2100. Mostly attributable to global warming, the tropical Indian Ocean will likely be in a “near-permanent heatwave state” and accelerate coral bleaching, seagrass destruction, and loss of kelp forests, affecting the fisheries sector adversely, said an analysis led …

THESE two Indian cities may be submerged within a few decades: Study

Live Mint  

A report published on Nature Climate Change has now shown that several Asian megacities run the risk of getting submerged within the next few decades owing to the threat of rising levels. While many shoreline Asian megacities were already at risk of flooding, the study suggests that previous analysis underestimated the degree of sea level rise and subsequent flooding caused …
