Examining short- and long-term risks of global warming methane “time bomb”. Scientists explain the evidence.

Greta Thunberg realized at a young age the lapse in what several climate experts were saying and in the actions that were being taken in society. The difference was so drastic in her opinion that she decided to take matters into her own hands.

The Sun delivers more energy to Earth in one hour than all of humanity uses in an entire year. How can we make this power more accessible to everyone, everywhere? Solar designer Marjan van Aubel shows how she’s turning everyday objects like tabletops and stained glass windows into elegant solar cells — and shares her vision to make every surface a power station.

Bill Nye is just as frustrated as you are with Donald Trump’s climate change denial — but he’s confident the next generation of progressives will bring about action.

Introduced by Minority Leader of the U.S. House of Representatives Nancy Pelosi, Mike Bloomberg shares the trailer for Bloomberg Philanthropies and RadicalMedia’s new film, “Paris to Pittsburgh,” and delivers remarks Summit on the U.S. commitment to make progress on the goals of the Paris Agreement and more at the Global Climate Action.

This video is a product of an AGCI workshop on Understanding the Causes and Consequences of Polar Amplification that took place in 2017.

What if we took out more greenhouse gases than we put into the atmosphere? This hypothetical scenario, known as “drawdown,” is our only hope of averting climate disaster, says strategist Chad Frischmann. In a forward-thinking talk, he shares solutions to climate change that exist today — conventional tactics like the use of renewable energy and better land management as well as some lesser-known approaches, like changes to food production, better family planning and the education of girls. Learn more about how we can reverse global warming and create a world where regeneration, not destruction, is the rule.

The Great Barrier Reef is in trouble. With its coral dying in record numbers, CNN explores the wonders of the reef and meets the scientists who are trying to save it.

Earth Overshoot Day marks the date, each year, when humans use more natural resources than our planet can renew in that entire year. This date is arriving earlier each year, since it started being observed in 1986. This year it arrived on 1 August in 2018. This means that as a species, we are currently using up nature’s resources around 1.7 times faster than the planet’s ecosystems can regenerate them, through our consumption rates and a growing population.

Dramatic declines in costs over recent years are making solar a ‘go to’ source across America, as corporations, investors, and electric utilities help drive increasing demand.

What do you think of when you hear the words “climate change?” Chances are, you might think of sad nature, somewhere far away. But climate change also affects humans, in every corner of the world, including the corner where you live, and where I live. It impacts the people and places we see everyday, and it will impact some of us more than others.

The one thing Katherine Hayhoe wishes we did about climate change.

Wooden skyscrapers are an ambitious and innovative solution to the problems posed by urbanisation. Not only are they faster to build, they have smaller carbon footprints than high-rises made of concrete and steel.

Earth’s global surface temperatures in 2017 were the second warmest since modern record-keeping began in 1880, according to an analysis by NASA.

President Donald J. Trump announced a new national security strategy for the United States, removing climate change from the list of global threats. Maybe he should have consulted with the U.S. Military first?

Deep in the Himalayas, on the border between China and India, lies the Kingdom of Bhutan, which has pledged to remain carbon neutral for all time. In this illuminating talk, Bhutan’s Prime Minister Tshering Tobgay shares his country’s mission to put happiness before economic growth and set a world standard for environmental preservation.

Carbon Tax and Cap and Trade are two different policies that aim to reduce carbon emissions and increase sustainable consumption.

NASA created a visualization of the ocean garbage patches using data from floating, scientific buoys that NOAA has been distributing in the oceans for the last 35-years.

Climate change is unfair. While rich countries can fight against rising oceans and dying farm fields, poor people around the world are already having their lives upended — and their human rights threatened — by killer storms, starvation and the loss of their own lands. Mary Robinson asks us to join the movement for worldwide climate justice.

A skyrocketing demand for food means that agriculture has become the largest driver of climate change, biodiversity loss and environmental destruction. Jonathan Foley shows why we desperately need to begin “terraculture” — farming for the whole planet.

Senator Sanders spoke about climate change science and compared critics of climate change to deniers of the Nazi threat in the 1930s.

In 4 minutes, atmospheric chemist Rachel Pike provides a glimpse of the massive scientific effort behind the bold headlines on climate change, with her team — one of thousands who contributed — taking a risky flight over the rainforest in pursuit of data on a key molecule.
