A huge swath of the Antarctic ice cap is already crumbling, and preventing the thawing of the ice caps might now be impossible, a major new study suggests. The melting of the area studied alone would raise the world's sea level by nearly four feet, and total thawing could lead to up to a 12-foot surge in sea levels. Still, that probably won't happen for a century or two, since the ice is melting slowly, researchers say

A new study says that as the world gets warmer, parts of North America, Europe and Asia could see more frequent and stronger visits of that cold air. Researchers say that's because of shrinking ice in the seas off Russia.

As the Arctic melts, oil companies are moving in to drill for more oil. Next year, the Norwegian owned oil company Statoil will drill further north than ever - unless we stop them. An unprecedented case was filed this morning that could do just that. This case is about holding back the oil industry at this final frontier, it is about protecting the beautiful Arctic, and it is about people stepping up to hold governments to account. If we win, millions of barrels of oil could be kept in the ground. We will argue in court that we must take action to keep the Paris climate agreement on track, and we will invoke Norway's constitutional right to a healthy and safe environment for future generations.

While national leaders spout optimistic platitudes celebrating the great achievement of the globally unifying Paris Agreement on climate, environmentalists note that there is little in the way of substantial action plans behind the many promises made last December. Meanwhile, the most intense El Niño in history is leaving in its wake a world gripped by 7 months of record high temperatures; drought, water shortages, and famine (especially in India and Africa); wildfires (Fort McMurray, Canada); record coral bleaching; and a fast shrinking Arctic ice cap that set stunning early melt records this winter and spring.

Sea level rise is caused primarily by two factors related to global warming: the added water from melting land ice and the expansion of sea water as it warms. The first chart tracks the change in sea level since 1993 as observed by satellites. The second chart, derived from coastal tide gauge data, shows how much sea level changed from about 1870 to 2000.

But climate change is making it harder for resort owners and tour operators to make good on this promise. Climate change is having more of an impact on tourist destinations by eroding beaches and bleaching coral reefs. Mountain destinations are not immune either, as a warming climate melts glaciers and snow pack. The latest bleaching of the Great Barrier Reef has again brought to the forefront the growing impact of climate change on tourist destinations. According to the Great Barrier Reef Marine Park Authority, warmer than usual waters have caused bleaching (PDF) along much of the reef, and have killed nearly a quarter of its coral.

Climate change is already taking a serious toll on the planet, leading to heat waves, water shortages, melting ice caps, dying coral reefs and the extinction or migration of fish stocks, according to a report from the U.N.'s Intergovernmental Panel on Climate Change. Decisions made -- or left unmade -- by policymakers in the immediate future will shape global society for the rest of the century, the panel's report warns. "Nobody on this planet is going to be untouched by the impacts of climate change," said Rajendra K. Pachauri, the panel's chairman

A new Google-powered tool called Google Earth Engine is helping environmental groups and researchers to keep tabs on problems including Amazonian deforestation, overfishing, sea-ice melt and the spread of diseases. The tool's real-time data trove and mapping features make it easier to stay on top of the wealth of data now available, researchers say. "When you visualize it, you can get it at the gut level. ... You can see it happening," says Randy Sargent of Carnegie Mellon University.

The team, at the Istituto Italiano di Tecnologia (IIT) in Genoa, is using coffee grounds to clean water, turning the grounds into a foam that can remove heavy metals like mercury. "We actually take a waste and give it a second life," says materials scientist Despina Fragouli. Her team took spent coffee grounds from IIT's cafeteria, dried and ground them to make the particles smaller. They then mixed the grounds with some silicon and sugar. Once hardened, they dipped it in water to melt away the sugar, which leaves behind a foam-like material.

In the Arctic Ocean, some ice stays frozen year-round, lasting for many years before melting. But this winter, the region hit a record low for ice older than five years.

Each of the first six months of 2016 set a record as the warmest respective month globally in the modern temperature record, which dates to 1880, according to scientists at NASA's Goddard Institute for Space Studies (GISS) in New York. The six-month period from January to June was also the planet's warmest half-year on record, with an average temperature 1.3 degrees Celsius (2.4 degrees Fahrenheit) warmer than the late nineteenth century.

For thousands of years, sea level has remained relatively stable and human communities have settled along the planet's coastlines. But now Earth's seas are rising. Globally, sea level has risen about eight inches (20 centimeters) since the beginning of the 20th century and more than two inches (5 centimeters) in the last 20 years alone. All signs suggest that this rise is accelerating.

Continuing greenhouse gas emissions and climate change could cause Nepal's Everest region to lose 99% of its glaciers by the end of the century, researchers say. "The numbers are quite frightening," said Joseph Shea, a glacier hydrologist at Nepal's International Center for Integrated Mountain Development
