NASA’s Earth Minute: Sea Level Rise
1:30 | Since 1880, the global sea level has risen 8 inches (20 cm); by 2100, it is projected to rise another 1 to 4 feet (30-120 cm).
Guðni Elísson – Earth2015
15:22 | Hot future, cold war. Climate science and climate understanding.
Water vapor amplifies warming
5:27 | Keah Schuenemann’s lecture explains how carbon dioxide affects water vapor in our atmosphere and also how the two greenhouse gases interact to form a positive feedback loop.
The role of clouds in climate change
5:51 | Peter Jacobs talks about one of the more complicated questions in climate science: how will clouds change in a changing climate?
Making sense of the slowdown
6:39 | Climate change is real, so why the controversy and debate?
The Little Ice Age
5:42 | In this lecture, Andy Skuce explains what the so-called “little ice age” was and what caused it. Most importantly, natural factors coming out of the little ice age cannot explain our current global warming.
Confused decline
5:26 | Peter Jacobs explains climate proxies, which estimate temperatures in the Earth’s past. In particular, he looks at the divergence problem, where some tree-ring proxies diverge from recent instrumental measurements.
Medieval warm period
5:47 | Robert Way examines the Medieval Warm Period and how it compares to today’s temperatures.
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.

Knowledge Based Consensus
7:56 | When should a consensus be considered scientific, or “knowledge-based”?
Scientific method
