The gas-rich United Arab Emirates will invest $35 billion in clean energy by 2021 as it seeks to reduce its dependence on fossil fuels following crude's global price slide, it said Sunday.

"By 2021, our investments in nuclear and solar projects will reach $35 billion (31 billion euros)," Energy Minister Suhail al-Mazrouei said at an energy conference in Abu Dhabi.

The Philippine island of Cebu suffered its seventh straight day of haze on Saturday, the weather bureau said, as Southeast Asian countries battle pollution suspected to emanate from illegal fires on Indonesian plantations.

Monsoon winds blowing northeast from the Indonesian blazes towards the direction of the central Philippines could have carried the smog, state weather forecaster Romeo Aguirre told AFP.

Earth is on track for average warming of 2.7 degrees Celsius by 2100, outstripping the U.N. target, said an analysis Thursday of country pledges for curbing climate-altering greenhouse gas emissions.

While exceeding the U.N. goal of limiting overall warming to 2 Celsius (3.6 degrees Fahrenheit) over pre-Industrial Revolution levels, the number was an improvement on the 3.1 C forecast issued in September by Climate Action Tracker (CAT), a tool developed by a quartet of research bodies.

Indonesia's disaster chief on Thursday defended the country's efforts to fight forest fires that have blanketed Southeast Asia in choking haze, and said he believed rains would arrive within a month to finally douse the blazes.

"Are we able to manage the fires? The answer is clearly a yes... we are not overwhelmed, we can manage it and there is progress," National Disaster Management Agency chief Willem Rampangilei told reporters.

The Philippines pledged on Thursday to cut the archipelago nation's carbon emissions by 70 percent by 2030, pending financial support from developed countries.

President Benigno Aquino approved the country's climate change mitigation and adaptation plan, which is set to be implemented after 2020, spokesman Herminio Coloma said in a statement.

Sea-level rise along the Atlantic and Gulf coasts combined with more frequent and violent storms could increase flooding from the Northeast to Texas by several-hundredfold, according to a new study out Monday.

Over the past century, the East Coast has seen sea-level rise far above the 8-inch global average - up to a foot in much of the Mid-Atlantic and Northeast, including New York City. It is expected to increase as much as four feet by 2100, mostly due to the melting ice sheets as well as the expansion of the seawater as the oceans warm.

Most people know that global warming spells bad news for polar bears and other creatures that depend on Arctic sea ice. But it could have an unexpected effect on a kind of animal rarely considered in climate change debates: crocodiles.

According to a new study, climate change could lead to a huge population increase and diversification of crocodile species in North America and Europe.

What did Volkswagen do?

The company is said to have been caught cheating on American air pollution tests. Volkswagen installed sophisticated software known as "defeat devices" in the electronic control module of diesel vehicles issued between 2008 and 2015. This software was able to sense when emissions testing was in progress based on the position of the steering wheel, vehicle speed, the duration of the engine's operation and barometric pressure. Once the software picked up on these inputs, it went into a type of "test mode" when the front wheels of the car were on a dynamometer. This allowed emissions controls to run full-tilt during official testing, but emitted 10 to 40 times the legal amount while on the road.

Last month, wildlife photographer Kerstin Langenberger shocked the world when she revealed a horrifying photograph of a severely emaciated polar bear, shot on the Norwegian island of Svalbard. In a Facebook post, she expressed her concerns about the health of the Svalbard polar bears and the ways climate change might be affecting the Arctic. Her photo, visible here, quickly went viral — having been shared more than 50,000 times since then.

So when Langenberger’s photo surfaced, the immediate conclusion for many people was that the starving bear was the victim of warming-induced ice-melt in the Arctic. But while this is possible, experts are cautioning the public not to make the image the new face of climate change just yet. As a recent Live Science article pointed out, that bear’s condition could have been caused by a variety of other factors. And while climate change remains a serious long-term threat to polar bears, immediately blaming global warming for a single bear’s starvation could even be considered misleading, or could obscure some of the other challenges bears face in the short term.

The Arctic is one of the most vulnerable parts of the world when it comes to climate change, and has the potential to contribute some costly climate-related effects, such as sea-level rise from melting glaciers. But one of the biggest emerging talking points in conversations about climate change in the Arctic involves something else — permafrost.
