West Antarctica's Getz Glaciers Flowing Faster

Wherever you look in West Antarctica right now, the message is the same: Its marine-terminating glaciers are being melted by warm seawater.
Scientists have just taken a detailed look at the ice streams flowing into the ocean along a 1,000 km-stretch of coastline known as the Getz region.
It incorporates 14 glaciers - and they've all speeded up.
Since 1994, they've lost 315 gigatonnes of ice - equivalent to 126 million Olympic swimming pools of water.
If you put this in the context of the Antarctic continent's contribution to global sea-level rise over the same period, Getz accounts for just over 10% of the total - a little under a millimetre.
This is the first time anyone has done a really detailed study of this area of West Antarctica. It's very inaccessible to people to go and do field work because it's so mountainous; most of it hasn't ever been stepped on by humans.

World's Largest Iceberg Disintegrates Into Alphabet Soup

The ocean north of Antarctica has turned into an alphabet soup of broken icebergs.
In a satellite photo, the jagged outlines of 11 fractured icebergs swirl around a remote, penguin-filled island called South Georgia, located about 940 miles (1,500 kilometers) northeast of the Antarctic Peninsula.
Each frozen chunk is a piece of the once-mighty iceberg A-68a, which held the title of the world's largest iceberg for more than three years before shattering into a dozen pieces a few weeks ago.
Now, each broken bit of the puzzle has its own name, beginning with A-68b, and ending with A-68M.

Edinburgh Aims to Become Sanctuary for Swifts as Numbers Decline

Conservationists are hoping to turn Edinburgh into a sanctuary for swifts after a drastic decline in the bird's population.
Numbers fell by more than 50% in the UK between 1995 and 2016, when the estimated average population dropped from 125,500 to 59,000.
One of the biggest challenges that the species faces is the loss of nesting sites in older buildings, which are often blocked off during renovation work or lost when buildings are demolished.
The Edinburgh Swift City Project is asking people to make boxes in a bid to encourage pairs to nest and breed.
Residents are also being urged to report any sightings of swift screaming parties - groups of two or more swifts flying at low level while calling loudly, which means they are breeding nearby.
Hubs are being created along a cycle route through the city to raise awareness, and a huge mural depicting the bird's long migration path between Africa and Europe is also being planned.
The bird conservation charity RSPB Scotland is currently searching for a building in the city and an artist to create the mural.

TN to Get its Fifth Tiger Reserve

In what comes as a major boost for wildlife and nature conservation, Tamil Nadu will now have a new tiger reserve, encompassing over one lakh hectares of land that falls under the Meghamalai Wildlife Sanctuary and Srivilliputhur Grizzled Squirrel Wildlife Sanctuary.
The Union government granted approval for the state's fifth tiger reserve following a letter from the Tamil Nadu government on January 7. This was based on the technical committee meeting that was held on January 22. The state government will notify the reserve as soon as the Union government does.
The Forest Department's proposal was to declare 1.48 lakh hectares of land encompassing Meghamalai Wildlife Sanctuary, Srivilliputhur Grizzled Squirrel Wildlife Sanctuary and Tirunelveli Wildlife Sanctuary as Tamil Nadu's fifth tiger reserve.
With the creation of Periyar and Kalakkad Mundanthurai Tiger Reserves, the water needs of several southern districts have mostly been taken care of. With the new Srivilliputhur – Megamalai Tiger Reserve, the forests will be better protected and the rivers and streams will start flowing again.
