Greenhouse Gases

Pandemic shows we need a Herculean effort to slow global warming

The COVID-19 pandemic has taught us we’re in this together. A united, global effort stands the best chance of eradicating this deadly virus. Same goes for the all-important charge to keep our planet from overheating to the point of no return. Climate change solutions are possible, with the right approach.

Greenhouse gas emissions: What is the difference between stock and flow gases?

While all greenhouse gases (GHG) have a warming effect on our planet, this warming effect is not equivalent across all GHG. These gases behave differently in the atmosphere and their long-term effects on climate change vary. The major factor contributing to a GHG warming effect is whether it is a stock or flow gas.  

The Biogenic Carbon Cycle and Cattle

Mitloehner lab Ph.D. student Samantha Werth, M.S. explains that cattle are often thought to contribute to climate change because they belch methane (CH4), a greenhouse gas. While this is true, cattle do belch methane, it is actually part of an important natural cycle, known as the biogenic carbon cycle.

How Do Cattle Produce Methane?

When animals are criticized for the part they play in climate change, most often it’s the cattle that take it on the chin. While beef and other products that come from cattle are popular in the United States and abroad, what cattle are often singled out for is the result of a digestive system that differs from those of poultry and swine, two other favorite sources of protein. 

Is Meat Bad for the Environment?

Perhaps more helpful than asking if meat is bad for the planet is engaging in a dialogue about the effect meat and dairy production have on the environment and what the downside and significant upside of animal agriculture are all about.

What is the Greenhouse Gas Effect?

The term “greenhouse gas effect” generally has negative connotations these days, but that hasn’t always been the case. The phenomena whereby certain gaseous compounds trap the sun’s heat and act as a blanket of insulation around Earth is what makes our planet hospitable to life. (See “What is a Greenhouse Gas?”)


What is Carbon Sequestration and How Does it Work?

Carbon sequestration is the process of capturing, securing and storing carbon dioxide from the atmosphere. The idea is to stabilize carbon in solid and dissolved forms so that it doesn’t cause the atmosphere to warm. The process shows tremendous promise for reducing the human “carbon footprint.” There are two main types of carbon sequestration: biological and geological.
