climate and atmosphere

What has contributed to the increased amount of greenhouse gases in the atmosphere today?

Expert Solution

Explanation:

The most talked about greenhouse gas is Carbon Dioxide. The things that are increasing the amount of it today are the burning of fossil fuels (coal and gas for example, are carbon based and release carbon dioxide when burned), and the depletion of forests as plants are what take carbon dioxide out of the atmosphere.

The next greenhouse gas that is increasing (although not nearly as quickly) is methane. It is released from rotting material and as a byproduct of digestion. This is increasing in a couple of ways. The diet that most meat producing animals receive is not the best diet to reduce the amount of methane produced (yes I am talking about cow farts). Furthermore the sheer number of farm animals is quite high and therefore the amount of methane they produce is high.

The other thing that increases methane is the thawing of permafrost. This frozen material does not rot (cause it's frozen) so when it thaws and begins to rot it releases methane. Permafrost is thawing due to global warming which is due to increased greenhouse effect, so this is a feedback loop that is difficult to stop.

It depends on which greenhouse gas you are referring too.

True/False. If humans could stop emitting carbon dioxide into the atmosphere, then the eﬀects of climate change would go away and the climate would return to “normal” within a decade or two. Explain. Credit is given for the thoroughness of the explanation.

Convincing Others that Climate Change is Real Climate change remains a somewhat controversial topic in the media and in politics, while nearly every climate scientist is in agreement about what is happening right now. If there is so much data, why are there still so many critics of climate change? Search the internet for one argument that either climate change is not happening at all, or that humans are not largely responsible for what is happening. Choose an argument that...

"Global Climate Change" refers to shifting trends in the long-term weather patterns ("climate") across the globe, and includes phenomena such as global warming. At its root is a steady increase in the atmospheric concentration of several gases called "greenhouse gases", some of which are released through burning fossil fuels such as gasoline, coal, and natural gas. One greenhouse gas is carbon dioxide, an input for photosynthesis and an output of cellular respiration. Your assignment for this Discussion Board to is...
