Future Ice Age
4:54 | Dana Nuccitelli looks at what caused ice ages in the past and explains why we don’t expect them to occur in the foreseeable future.
Climate science in the 1970s
5:56 | What were climate scientists thinking and publishing in the 1970s, before there was empirical evidence that the globe was warming? Daniel Bedford explains.
Principles that models are built on
4:43 | Dana Nuccitelli explains the principles that climate models are built on: fundamental physical laws. No one can know the future for certain, but these models allow us to make educated decisions looking forward.
Tendency to underestimate climate impacts
5:39 | Keah Schuenemann explains the role of the IPCC and their tendency to underestimate climate impacts.
Weather vs climate
6:23 | Keah Schuenemann explains the differences between weather models and climate models.
Ancient CO2 levels
5:48 | Observing the effects of ancient CO2 levels and their correlation to ancient climate change can inform us what to expect today.
The greenhouse effect
4:32 | Mark Richardson takes us to the Reading University Atmospheric Observatory to explain how the greenhouse effect works. He concludes by busting the myth that the greenhouse effect violates the 2nd law of thermodynamics.
Taking up residence
5:15 | Gavin Cawley explains the carbon cycle, how human activity is causing an increase of CO2 in our atmosphere, and uses bank accounts to show how we can know humans are increasing atmospheric CO2.
Reinforcing feedback
5:33 | Ice core records tell us global warming causes the ocean to emit more CO2. More atmospheric CO2 in-turn traps more heat, making this is a reinforcing feedback loop.
Measuring from space
4:24 | Sarah Green explains how satellites monitor outgoing radiation to measure global warming. She concludes by busting the myth that CO2 must be unimportant in our atmosphere because it is only a trace gas.
Structure of the atmosphere
4:50 | Mark Richardson examines one of the human fingerprints being observed in the structure of the atmosphere and debunks a myth about the elusive tropospheric hot spot.
Heat in the City
6:09 | This video features Kevin Cowtan talking about urban heat and temperature records.
Wavy Jet Stream
6:23 | Keah Schuenemann explains what the jet stream and the “polar vortex” effect it is having in the United States.
Consensus of Evidence
5:26 | This lecture introduces some “human fingerprints” of warming we observe in our climate system.
Consensus of Papers
6:50 | What does peer-reviewed literature have to say about climate change?
Consensus of Scientists
6:57 | This video covers several studies showing the high levels of agreement about anthropogenic global warming among scientists, and concludes by debunking the infamous “Global Warming Petition Project.”
Knowledge Based Consensus
7:56 | When should a consensus be considered scientific, or “knowledge-based”?
Scientific method
6:01 | Climate change is real, so why the controversy and debate? Learn to make sense of the science and to respond to climate change denial.
What do you say to someone who says the science isn’t settled?
2:16 | Gavin Schmidt, Kevin Anderson, Erik Conway and Erick Fernandes tell us what they say to someone who asks if the science is settled.
Why People Don’t Believe In Climate Science
7:34 | Here’s what psychologists and sociologists have to say about why some people don’t believe in climate science.
A visual tour of the world’s CO2 emissions
2:33 | A new high-resolution computer model created by NASA shows CO2, the greenhouse gas driving global warming, as you’ve never seen it before.
Climate Science: What You Need To Know
6:20 | Whether you already trust in the science, you’re undecided, or you disagree with all this, this video is for you!
NASA’s Earth Minute: Gas Problem
1:42 | Greenhouse gases are vital to life on Earth, but the growing concentration of certain gases, such as carbon dioxide, is throwing the planet’s delicate balance out of whack.
NASA’s Earth Minute: Earth Has a Fever
1:40 | Earth’s average temperature has risen over 1º F in the past century. It is projected to rise an additional 3º to 10º over the next 100 years.
NASA’s Earth Minute: Usual Suspects
1:30 | NASA’s ongoing Earth science missions, research and computer models help us better understand the long-term global changes occurring today through both natural and manmade causes.
Naomi Oreskes: Why we should trust scientists
19:14 | Many of the world’s biggest problems require asking questions of scientists — but why should we believe what they say?
Weather Versus Climate Change
2:09 | Neil deGrasse Tyson breaks down the differences between weather and climate change.
NASA Hangout: Ask a Climate Scientist
51:40 | This NASA Google+ Hangout on Mon., Sept. 30, at 12 p.m. EDT, caps a month-long campaign called Ask A Climate Scientist.
Michael Mann: IPCC Downplaying Higher End Scenarios?
7:46 | Michael Mann argues that the IPCC is more conservative and reticent in what they are willing to conclude given the body of existing evidence.
Ask a Climate Scientist: CO2 and Temperature
1:40 | Is there any merit to the studies that show that historical CO2 levels lag behind temperature, and not lead them?
Ask a Climate Scientist
1:20 | Have a question that’s always confounded you about Earth’s climate?
A History of Earth’s Climate
11:19 | A look at the history of climate change on Earth can give us some much needed perspective on our current climate dilemma.
Keeping Up with Carbon
5:15 | NASA Climate Change
Climate Change Overload
3:47 | NASA Climate Change
The Ocean: A Driving Force for Weather and Climate
6:00 | This animation shows the importance of Earth’s oceanic processes as one component of Earth’s interrelated systems.
How to talk to an Ostrich: “We don’t know enough…”
2:21 | It’s true that Earth’s a massive jigsaw puzzle, with lots of pieces intricately fitting together. But, Richard Alley argues, we already know enough to see the Big Picture.
