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 …

Grazed and Confused? How much can grazing livestock help to mitigate climate change?

Grazed and Confused? How much can grazing livestock help to mitigate climate change?

Grazed and confused? How much can grazing livestock help to mitigate climate change? These are ruminants. Ruminants have specialized stomachs containing microorganisms. This allows them to eat hard-to-digest plants like grass, unlike pigs and chickens. However, these microorganisms also produce methane, a powerful greenhouse gas. And the more fibrous the ruminants’ diets, the more methane …

Greenhouse gases emissions and concentrations

Greenhouse gases emissions and concentrations

How can we stop messing with the climate? To start answering this question, it’s useful to break the carbon climate problem into four components– emissions, concentrations, climate change, and climate impacts. First, the emission of carbon dioxide and other long-lived greenhouse gases that can alter the climate. Emissions are the human-caused flow of greenhouse gases …

How does climate change affect biodiversity?

How does climate change affect biodiversity?

(gentle music) – [Instructor] What are some of the global threats so biodiversity? First, I want to emphasize that virtually everything we do locally has global consequences. When we talk about something like a greenhouse gas or a pollutant, that’s something we produce locally from our car or from other things that make up so …

Seasonal Changes in Carbon Dioxide

Seasonal Changes in Carbon Dioxide

This is carbon dioxide, or CO2, in the Earth’s atmosphere. It is derived from a synthesis of observed and simulated data. Reds and yellows show regions of higher than average CO2, while blues show regions lower than average. The pulsing of the data is caused by the day/night cycle of plant photosynthesis at the ground. …
