India to Soon Launch Deep Sea

According to a top official of the Ministry of Earth Sciences, India will soon launch an ambitious 'Deep Ocean Mission' that envisages the exploration of minerals, energy and marine diversity of the underwater world, a vast part of which still remains unexplored.
The required approvals are being obtained for the futuristic and game-changing mission.
The mission is expected to cost over Rs. 4,000 crore, will give a boost to efforts to explore India's vast Exclusive Economic Zone and Continental Shelf.

Sentinel-6: 'Dog Kennel' Satellite to Measure Sea-level Rise

A satellite that will be critical to understanding of climate change was launched from California.
Sentinel-6 Michael Freilich will become the primary means of measuring the shape of the world's oceans.
Its data will track not only sea-level rise but reveal how the great mass of waters are moving around the globe.
The Sentinel is a joint endeavour between Europe and the US, and will continue the measurements that have been made by a succession of spacecraft, called the Jason-Topex/Poseidon series, going back to 1992.
These earlier missions have shown unequivocally that sea levels globally are rising, at a rate in excess of 3 mm per year over the 28-year period. And their most recent data even suggests there is acceleration under way, with levels recorded as going up at over 4 mm per year.

Global Map of Bees Created in Conservation First

Scientists have mapped the distribution of all 20,000 bee species on earth.
As per researchers from Singapore and China, the new global map of bees will help in the conservation of the insects we rely on to pollinate our crops.
Bees are facing pressure on their population numbers from habitat loss and the use of pesticides.
Yet little is known about the array of species living on every continent save Antarctica, ranging from tiny stingless bees to bees the size of a human thumb.
Millions of records have been combined to create the first maps of global bee richness, and understand why we see these patterns.
These maps and framework, can then form the basis of future work, enabling to better understand patterns of bee richness and ensure that they are effectively conserved into the future.

Hurricane Iota: Strongest Atlantic Hurricane of the Year

At least 30 people have lost their lives as the strongest Atlantic hurricane of the year ripped through areas of Central America.
Tens of thousands were forced to flee their homes as Hurricane Iota hit Nicaragua and neighboring countries.
The rainfall caused mudslides and potentially deadly flash flooding and river flooding.
Winds of 257km/h (160mph) have hit areas still recovering from Eta, a major hurricane that hit two weeks ago.
Iota is the strongest Atlantic hurricane of the year and only the second November hurricane to reach category five — the last was in 1932.
This year's Atlantic hurricane season has broken the record for the number of named storms. Only for the second time on record, officials have had to start using the letters of the Greek alphabet to start storm names after running out of names on its traditional alphabetical list.

France's Biggest Glacier is Melting

France's largest glacier once looked so mighty sliding down the granite slopes of the Mont Blanc, Western Europe's tallest peak that early explorers struggled to find the words to capture it.
British adventurer William Windham was one of the first tourists to explore the glacier in 1741.
La Mer de Glace, the Sea of Ice. At that time and until the late 1980s, thousands of years of ice covered the steep valley. Visitors walked from the nearby town of Chamonix to Montenvers, where the glacier was so close they only had to hike down a few metres to touch it.
