Over the past century, the concentration of greenhouse gases in the atmosphere has_____ This has led to _____heat being held in the troposphere, where infrared radiation is _____ likely to encounter a greenhouse gas molecule and be_____
the first dash waved up and down, increased, decreased and been unchanged
the second dash More, less the same amount of
the third dash more or less
the last dash transmaitted, absorbed and re-emmitied, reflected down
I think increased, more, more and transmaitted I really need help thank you.
increased
more
more
absorbed and then re-emitted back toward earth
The high frequency (energy) photons from the sun tend to scoot through the atmosphere and warm up the earth surface. That causes the earth surface to emit lower frequency infrared (hot) photons upward. CO2 or CH4 molecules in the air absorb those infrared rays and get hot, radiating them in all directions, including back to the ground heating it up more.
Thanks Damon that was such help.

Just found that, nice video explains beautifully.
Over the past century, the level of greenhouse gases in the atmosphere has risen substantially. These greenhouse gases are linked to global warming. The leaders of many nations are calling for a large decrease in the amount of greenhouse gases emitted into the atmosphere. Which of the following would be a cost of dealing with the greenhouse gas problem?
@Damon was correct, thx man LOL
There are several potential costs associated with dealing with the greenhouse gas problem:
1. Economic costs: Reducing greenhouse gas emissions may require significant investments in new technologies, infrastructure, and changes in consumption habits. These costs could affect business profitability and overall economic growth.
2. Job losses: Some industries, particularly those heavily reliant on fossil fuels, may experience job losses as they shift to lower-emission technologies.
3. Higher costs for consumers: Consumers may face higher prices for goods and services that require significant energy inputs or that have long supply chains.
4. International cooperation: Addressing the global problem of greenhouse gas emissions would likely require international cooperation, which can be difficult to achieve due to conflicting interests and differing priorities among countries.
5. Political costs: Policy and regulation changes needed to address greenhouse gas emissions could lead to political backlash if they are perceived as negatively impacting certain communities or groups.
