On Nov. 10, 2016, scientists on NASA's IceBridge mission photographed an oblique view of a massive rift in the Antarctic Peninsula's Larsen C ice shelf. Icebridge, an airborne survey of polar ice, completed an eighth consecutive Antarctic deployment on Nov. 18.

Ice shelves are the floating parts of ice streams and glaciers, and they buttress the grounded ice behind them; when ice shelves collapse, the ice behind accelerates toward the ocean, where it then adds to sea level rise. Larsen C neighbors a smaller ice shelf that disintegrated in 2002 after developing a rift similar to the one now growing in Larsen C.

The IceBridge scientists measured the Larsen C fracture to be about 70 miles long, more than 300 feet wide and about a third of a mile deep. The crack completely cuts through the ice shelf but it does not go all the way across it – once it does, it will produce an iceberg roughly the size of the state of Delaware.

Many species will not be able to adapt fast enough to survive climate change, say scientists.

A study of more than 50 plants and animals suggests their ability to adapt to changes in rainfall and temperature will be vastly outpaced by future climate change.

Amphibians, reptiles and plants are particularly vulnerable, according to US researchers.

And tropical species are at higher risk than those in temperate zones.

If an infectious disease was killing 7 million people a year, it would be ludicrous to work to allay its impact decades from now rather than taking immediate action against it. Yet that is exactly how we are approaching the causes of climate change, which are both immediate and long-term killers.

This week’s “airpocalypse” in New Delhi shows just how urgently action is needed to prevent the air pollution that is not only damaging our planet and human health in the long term but killing millions of people around the world in the present.

13 November 2016 – Ten days after the entry into force of the landmark Paris Agreement, dozens of heads of State and Government are expected on Tuesday at the United Nations Climate Change Conference (COP 22), which started in Marrakech, Morocco, on 7 November 2016.

Before the Conference wraps up on 18 November, State Parties hope to define the rules for the accord and to lay out a viable plan for providing at least $100 billion a year to developing countries to support climate action.

Adopted by 196 States Parties to the UN Framework Convention on Climate Change (UNFCCC) last December, the Paris Agreement, so-named after the French capital where it was approved, aims to strengthen the global response to the threat of climate change by keeping the global temperature rise this century well below 2 degrees Celsius above pre-industrial levels and to pursue efforts to limit it to 1.5 degrees Celsius. It entered into force in record time on 4 November 2016.
