The Science of Climate – Episode 3 – Greenhouse Gases

(female) Greenhouse gases trap heat in our atmosphere. This trapped heat can then cause Earth’s average temperature to increase from 0 to 59 degrees Fahrenheit. I wish it was 0 to 59 degrees warmer in here. I just wish it was Fahrenheit. What does that even mean? Enough with the chattering. Those were my teeth. …

Water Vapor and Climate

One of the most contentious of climate crocks is the role of water vapor in climate change. And climate deniers are always trying to “fog the issue”. But don’t be scared – Crock of the Week is here to make sure you don’t get sucked in. Water vapor is the most abundant Greenhouse gas but …

Understanding How Biomass Burning Impacts Climate Change

I’m Allison Aiken. I’m a research scientist at Los Alamos National Laboratory I study atmospheric aerosols. Atmospheric aerosols are particles that are in the atmosphere—and a particle being a small liquid or a solid. Aerosols optically can be divided into two different categories: absorbing aerosols and scattering aerosols. The absorbing aerosols are the ones that …

How Global Warming Works in 52 Seconds

How Global Warming Works in 52 Seconds

You may have heard of global climate change, which is often called “global warming.” We’ll quickly summarize the mechanism global climate change: Earth transform sunlight’s visible energy into infrared light, and infrared energy leaves Earth slowly because it’s absorbed by greenhouse gases. As people produce more greenhouse gases, energy leaves Earth even more slowly, raising …

Understanding why our Earth system is warming

Understanding why our Earth system is warming

[Music plays] [Music plays] (Dr Pep Canadell) Climate change it is like a global problem in the sense that the atmosphere is a commons for society. What we Australians do or somebody else does at the other end of the world, it actually all gets mixed within a year. So we really need to develop …

Explaining Climate Facts – 3/3 – Adaptation & Mitigation

Explaining Climate Facts – 3/3 – Adaptation & Mitigation

Climate change has already had clear impacts on natural and human systems. Over the coming decades, based on the various scenarios of emission of greenhouse gases, the range with which climate can change is quite wide, and depends on policy decisions that we take now. The risk of negative impacts results from the interaction between the climate-related …
