Climate change refers to long-term shifts in temperatures and weather patterns. These shifts may be natural, such as through variations in the solar cycle. But since the 1800s, human activities have been the main driver of climate change, primarily due to burning fossil fuels like coal, oil and gas.

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

Against the backdrop of turbulent markets and a crucial meeting of the COP26 conference on climate change in Glasgow, the 2021 World Energy Outlook

In this Our Changing Climate environmental video essay, I look at the environmental and social cost of the military and militarism. I narrow in on the United States military-industrial complex because it is by far the biggest military machine in the world.

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

From Iowa's farm fields to Washington's corridors of power, and from the algae-choked surface of the Great Lakes to the poisoned depths of the Gulf of Mexico, "The Ethanol Effect" investigates the human, environmental and political costs of growing and refining corn for ethanol in America.

In this Our Changing Climate environmental video essay, I look at the environmental and social cost of the military and militarism. I narrow in on the United States military-industrial complex because it is by far the biggest military machine in the world. I look at how the military and the military-industrial complex is a massive polluter in terms of both emissions and chemical waste. In addition, the video looks at whether or not these environmental and monetary burdens caused by the military-industrial complex are justified.

What's the big deal about a few degrees anyway? Find out in the last episode of Global Weirding. We'd like to thank everyone who has supported us along the way.

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.

What would happen if we started repairing things again - our toasters, vacuum cleaners, and air conditioning units instead of casting them aside and replacing them altogether? The world has an unhealthy obsession with stuff: we are somehow OK with creating a mountain of staggering trash as long as we can continue to satiate our appetite to buy, buy, buy.

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.

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

In December of 2017, China announced plans to roll out the largest carbon market in the world. Here's a look at how it's going to lower carbon pollution across the board.

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?

As we observe another anniversary of the Sept. 11, 2001 attack, Neta Crawford, political scientist and co-director of the Costs of War project, discusses the environmental impacts of the post-9/11 wars. Although greenhouse gas emissions from war were excluded from country reporting during the negotiation of the Kyoto Protocols, a major consequence of war is increased use of fossil fuels. During this event, Crawford will share her recent research calculating the U.S. military’s greenhouse gas emissions associated with the post-9/11 wars.

The destructive Carr wildfire in California is so big, it has created its own micro weather system, making it harder to predict what it will do next.

Bypassed in the ‘30s and '40s, one third of homes in Navajo Nation still have no access to grid electricity. Yet ironically, Nevada is a huge electricity exporter, with one of the biggest coal-fired plants churning out and exporting power. And, now a plan to shut down the plant could sorely cost the reservation. Bt, there might be a new opportunity.

Elizabeth Warren says she "has a plan for that" and fighting the climate crisis is no exception. In this video we take a look at her green manufacturing plan for America that she would enact if she's elected President of the United States in 2020.

According to a new report from the United Nations, our planet is in worse shape than at any other time in human history. The Trump Administration has done everything they can to do nothing about climate change. They just don’t listen to scientists. A lot of people don’t. Scientific fact is suddenly seen as some kind of partisan scare tactic. It endangers us all, so George Clooney is spearheading a new initiative to raise awareness of this foray into ignorance, and what he has to say is important.

Glacier: A Climate Change Ballet uses movement and dance to make climate change more emotionally immediate to audiences.

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

Greta Thunberg's speech at Davos.

Although levees can protect the people directly behind them, they make flooding worse for those upstream and across the river. Levees don’t make the water disappear, they simply displace it. We wanted readers to understand this idea in a visceral, visual way. We hired scientists at the University of Minnesota to build a room-sized model of a river. Then we added tiny houses.

Climate researchers are reviewing myriad studies of heat and human behavior, adding them up, and looking for sound conclusions about the relationship between temperature and economic productivity. Here's a short, colorful video guide to this new, and worrisome, research.

One of the most effective ways to protect the world's forests is by supporting the people who have been protecting them for generations. If we want to solve climate change, we have to support the land rights of indigenous peoples.

The Green New Deal has seemingly come out of the blue to become a litmus test for 2020 presidential hopefuls. But it didn't happen by accident. Alongside multiple members of Congress—notably Rep. Alexandria Ocasio-Cortez and Sen. Ed Markey—a group of young activists has pushed the plan into the headlines, working behind the scenes to reshape America's approach to the climate crisis.

In an exclusive interview, California Governor Jerry Brown (D) joins Chuck to discuss the aftermath of passing the gas tax in his state and how the wildfires this year have pushed him to "wake up the country, wake up the world" on climate change.

Up to eight feet below the ocean’s surface, former cod fisherman Bren Smith grows groves of a plant that he says could feed the planet and heal its oceans. “You know, for a fisherman it’s kind of weird to grow plants,” he said. “But this is the future.” Smith’s referring to kelp, a seaweed capable of soaking up five times more carbon than land-plants and filtering excess nitrogen out of the water. In Smith’s mind, kelp could become the new kale — and help reverse some of the dangerous effects of human-caused climate change.

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.

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.

They still look beautiful, but coral reefs are dying at staggering rates — experts project that 90 percent of the world's reefs will be gone by 2050. But a growing group of scientists around the world are searching for innovative solutions to make sure that doesn't happen.

We recently got an important update from the IPCC, the definitive source on the climate crisis. And while there's not a ton of good news, there are some bits of hope if we can ramp up our actions now.

Sea level rise can no longer be stopped, so it is urgent that we commence intelligent adaptation as a high priority, argues John Englander.

A video of Sen. Dianne Feinstein (D-CA) clashing with children over the Green New Deal has gone viral. Some say the widely-shared clip misrepresents the full discussion, cutting out Feinstein’s efforts to explain her own climate change plan. Others say it reveals a true generational divide over the urgency of climate action. Here is the raw, un-edited, 11-minute exchange. Decide for yourself.

This video (which is utterly fabulous, by the way, and watched by 22 million people, is then followed by a very extensive April 26, 2018 television news report by KREM 2 News — also great. Scott and Julie Brusaw have been working on this for ten years, each installation teaching them how to improve for the next installation. 

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.

A new government report says man-made climate change is already wreaking havoc on the U.S., and it will only get worse in the coming decades. The report from 13 federal agencies warns of more destructive wildfires, longer heat waves, and more powerful Atlantic hurricanes. Tony Dokoupil reports from an Indiana farm struggling with the effects.

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.

How do you talk to someone who doesn't believe in climate change? Not by rehashing the same data and facts we've been discussing for years, says climate scientist Katharine Hayhoe. In this inspiring, pragmatic talk, Hayhoe shows how the key to having a real discussion is to connect over shared values like family, community and religion -- and to prompt people to realize that they already care about a changing climate. "We can't give in to despair," she says. "We have to go out and look for the hope we need to inspire us to act -- and that hope begins with a conversation, today.”

TWith the ocean plastic cleanup, Boyan Slat has set up the first and the greatest ocean plastic cleanup campaign in history. And it all started about five years ago, with a graduation project about the plastic soup in the ocean.

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.

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.

One of the most effective ways to protect the world's forests is by supporting the people who have been protecting them for generations. If we want to solve climate change, we have to support the land rights of indigenous peoples.

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.

We should act as if this is an emergency, because it is. But part of that is understanding the tools and strategies countries are using to decarbonize and stabilize the climate. This is work that's already being done. We have already decoupled economic growth from the emission of greenhouse gasses which, frankly, was unthinkable just a couple decades ago.

Leading Scientists compare current Human pressure on the planet's life support systems to great Extinction events of the past.

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

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.  

In the face of Trump’s hostility to the landmark Paris Agreement, a U.S. delegation helped move it forward.

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.

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.
