Climate knowledge Here's your pocket guide to COP29—the world's largest climate conference COP29 took place in Azerbaijan and wrapped up on November 24, 2024. Read our key takeaways and outcomes.
Climate knowledge The key to fighting climate change In order to combat this crisis, we need to accept just how big the problem is.
Climate knowledge What is El Niño? El Niño is one piece in a long-term climactic pattern that influences the weather across the globe.
Climate knowledge What is the IPCC? The Intergovernmental Panel on Climate Change is the world's clearing house for climate-related science.
Climate knowledge Climate change and the Amazon rain forest An essential carbon sink is facing new threats.
Climate knowledge How much is the sea level rising? The rising seas are perhaps the most famous consequence of climate change—and they're already doing real damage.
Climate knowledge Nuclear power and climate change Essential tool or a dangerous distraction? Nuclear power tends to draw strong opinions on both sides.
Climate knowledge What is the problem with methane? So much attention is focused on carbon dioxide. But there's another villainous greenhouse gas out there that we need to rein in, too.
Climate knowledge What is the Anthropocene? Humans have re-shaped the Earth—so much that some scientists think we've entered a new geological era.
Climate knowledge Carbon Pricing 101 Carbon has a cost. The question is when we will pay for it—and how.
Climate knowledge Heat waves and climate change If we don't make a change, extended periods of hot weather pose a real threat.
Carbon Offsets 101 Carbon Offsets 101 Overwhelmed by the concept of carbon offsets? Here's where to start.
Climate knowledge What's the deal with fracking? Nasty nuisance or climate solution? Here's the full scoop.
Carbon Offsets 101 What is a carbon credit? A carbon credit is like a certificate: it records an accounted-for mass of greenhouse gas emissions. The simple move of tracking these gases opens many new possibilities.
Carbon Offsets 101 What distinguishes a high-quality carbon offset? It can be difficult to verify the impact of carbon offset projects—which is why transparency and rigor are key.
Carbon Offsets 101 What is a carbon offset? Is it really possible to make up for carbon emissions? In the first post of a three-part series, here's a look at the wide variety of projects trying to do just that.
Climate knowledge What's an aerosol? Scientists are still working to understand the climate impacts of these tiny particles.
Climate knowledge What is geothermal energy and why does it matter? The same forces that underlie Old Faithful might just be a key answer in the fight to slow climate change.
Climate knowledge The emerging story of the climate refugees The climate is changing. People are moving. But who is considered a refugee?
Climate knowledge What are the "planetary boundaries"? In an effort to ensure policy is informed by science, researchers have proposed a set of "planetary boundaries," red lines that we do not want to cross.
Climate knowledge What is the state of global climate policy? There are plenty of tools available to address the climate crisis. The obstacle, for now, is getting politicians to pick them up and put them to work.
Climate knowledge Is there a sustainable future for tourism? We all get wanderlust sometimes. But, given the climate crisis, we may have to rethink the way we hop across the world.
Climate knowledge Essential facts about pollution Despite decades of clean-up efforts, real concerns about pollution remain. We cannot afford to ignore our waste.
