Indian Ocean Warming at Faster Pace

According to a report by the Intergovernmental Panel on Climate Change (IPCC), the Indian Ocean is warming at a higher rate than other oceans, with scientists warning that India will witness increased heat waves and flooding, which will be the irreversible effects of climate change.
The authors of the Intergovernmental Panel on Climate Change's (IPCC) Sixth Assessment Report (AR6), "Climate Change 2021: The Physical Science Basis", said the warming of the ocean will lead to a rise in sea levels, which will contribute to more frequent and severe coastal flooding in low-level areas.

Ladakh Glacier Retreating, May Influence Summer and Winter Pattern

Establishing with observations that the Pensilungpa Glacier located in Zanskar, Ladakh, is retreating due to an increase in the temperature and decrease in precipitation during winters, a study shows how it is possible that the precipitation of summer periods at higher altitudes will change from snow to rain, and that may influence the summer and winter pattern.
Since 2015, a team of scientists from the Wadia Institute of Himalayan Geology (WIHG), Dehradun, has ventured to study the less explored region of the Himalayas, focusing on Zanskar, Ladakh.

Jurassic-Period Crocodile Ancestor Unearthed in Chile

Paleontologists have identified a new genus and species of small-sized mesoeucrocodylian from the fossilized remains found in the Patagonian mountains of southern Chile.
The newly-discovered crocodile species roamed Earth during the Late Jurassic epoch, some 148 million years ago.
The ancient creature lived alongside giant titanosaurs and other sauropod dinosaurs as well as smaller herbivorous species such as Chilesaurus diegosuarezi.
Previously recorded members of non-pelagic Jurassic Mesoeucrocodylia are the presumably fresh-water Atoposauridae, Goniopholididae and Paralligatoridae.

Massive Melting Event Strikes Greenland

Greenland's enormous ice sheet has been struck by a massive melting event, with enough ice vanishing in a single day to cover the whole of Florida in two inches (5 centimeters) of water.
Since July, roughly 9.37 billion tonnes (8.5 billion metric tonnes) of ice has been lost per day from the surface of the enormous ice sheet, twice its normal average rate of loss during. The huge loss comes after temperatures in north Greenland soared to above 68 degrees Fahrenheit (20 degrees Celsius), which is double the summer average.
High temperatures on July 28 caused the third-largest single-day loss of ice in Greenland since 1950; the second and first biggest single-day losses occurred in 2012 and 2019. Greenland's yearly ice loss began in 1990.
