A Climate Minute – Climate Science History

1824 – Joseph Fourier discovers the greenhouse effect. 1859 – John Tyndall shows H2O and CO2 absorb infrared. 1896 – Svante Arrhenius suggested human CO2 emissions would warm the planet. 1938 – Guy Callendar claimed warming was already apparent. 1956 – Gil Plass calculated adding CO2 would significantly change radiation balance. 1957 – Roger Revelle …

EU agricultural emissions: On the table

EU agricultural emissions: On the table

In 2012, agriculture was responsible for over 10% of total greenhouse gas emissions in the EU. Meat production is a significant factor. Producing 1 kilo of beef generates 65 times more CO2 than producing 1 kilo of potatoes. During digestion and excretion, livestock also release methane, a gas 23 times more powerful than carbon dioxide. …

The Truth about CO2

The Truth about CO2

What are two of the dirtiest words in the English language? Well, if you’re concerned with Global Warming as so many people are these days, the answer is obvious. The two words are “Carbon Dioxide.” Or as it is known by its chemical symbol — CO2. One atom of carbon and two atoms of oxygen. …

Climate Change is Boring

Climate Change is Boring

Climate change is boring. Don’t get me wrong. It is incredibly important. It is just that the story of climate change is not especially compelling. And that is when the carbon dioxide concentration reached 400 parts per million. When I started making this video I thought that everyone knew the story. But apparently I was …

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 …

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 …
