Energy Secretary Ernest Moniz said Friday that the Obama administration’s “all of the above” approach to energy sources means it seeks to reduce carbon dioxide from the energy sector.

Moniz sought to clarify the “all of the above” policy, saying that while certain energy sources such as wind and solar have no carbon emissions, the administration is truly committed to all forms of energy, including fossil fuels.

A major glacier in Greenland that holds enough water to raise global sea levels by half a meter has begun to crumble into the North Atlantic Ocean, scientists say.

The huge Zachariae Isstrom glacier in northeast Greenland started to melt rapidly in 2012 and is now breaking up into large icebergs where the glacier meets the sea, monitoring has revealed.

When it comes to his role in the climate change debate, we’ve learned in recent years to think of Bill Nye as a kind of warrior on behalf of reason — the guy who goes on cable TV and stands up to the voices of doubt and denial.

But that’s not the Nye of Bill Nye the Science Guy, the beloved kids show. And it’s not the picture you get from reading his new book Unstoppable: Harnessing Science to Change the World — which is fundamentally about changing how we get energy and thereby solving global warming. Here, Nye the inventor and engineer shines through — celebrating causes ranging from designing better batteries (doing so could get someone “rich, crazy rich,” he writes) to deploying fleets of robocabs in cities, to eventually powering rockets using hydrogen fuel.

For thousands of years, human beings have been helping evolution along by tinkering with the breeding habits of plants and animals.

Now, as one of our favorite underwater features faces serious threats from warming oceans, acidification, pollution and overfishing, scientists are rallying to breed a better future for coral reefs.

The UK is alone among G7 nations in dramatically increasing its fossil fuel subsidies, despite an earlier pledge to phase them out, a new report has found.

The revelation will embarrass ministers who want to take a leading role at a crunch UN climate change summit in Paris in December, but who have been sharply cutting support for green energy at home.

A major international climate conference in Paris will move forward later this month, and President Obama is still slated to attend, despite a series of attacks in the city Friday.

An administration official confirmed Saturday that Obama is still planning on going to Paris later this month to attend early sessions of the United Nations climate change conference.

Security fears in the wake of Friday's brutal slaying of 129 people in Paris threaten to overshadow a crunch climate summit to be launched by 120 world leaders in the French capital on November 30.

France's government has said it will not "give in" to terrorism and insists that the long-anticipated conference will go ahead, tasked with no less than producing a plan to rescue Earth's climate.

Primatologist Jane Goodall called Friday for bold action next month at high-stakes United Nations climate change talks.

The 81-year-old British chimpanzee expert said she has her "fingers crossed" heading into the summit in Paris, which will seek a comprehensive deal on curbing carbon emissions warming the planet.

Australia should “tell the story of the Pacific to the world” when global leaders sit down to climate change talks in Paris at the end of this month, Labor has said.

The impact of climate change on the nations of the Pacific is a focus for both the government and opposition ahead of COP21, where governments of more than 190 nations will gather to discuss a possible new global climate accord.

Insects should become a staple of people’s diets around the world as an environmentally friendly alternative to meat, according to a report by the UK government’s waste agency.

But persuading consumers to overcome “the yuck factor” will be a key issue, says the report by the Waste and Resources Action Program (Wrap) which assesses challenges to the development of the food system in the next 10 years.
