How did Fourier explain the fact that the Earth doesn’t keep getting hotter and hotter?
|
· Suggested the Earth emits energy back into space (infrared radiation)
· He calculated the balance between incoming solar radiation and outgoing infrared radiation should leave the Earth much colder
· thus he suggested the Earth’s atmosphere affected its temperature by preventing some infrared from escaping
|
|
How would the Earth’s climate be different if all atmospheric gases were transparent to all infrared radiation?
|
All infrared radiation would escape the atmosphere and the Earth would be much colder.
|
|
Why was John Tyndall interested in the affects of atmospheric composition on global climates?
|
He thought it might help him understand why the Ice ages began and ended
|
|
The estimates of Arrhenius and Hogbom, concerning human affects on the climate, included two important assumptions, understandable but mistaken. What were these assumptions?
|
1. Having atmospheric CO2 would reduce global temperatures by 8 degrees f. 2. Were such drastic changes in atmospheric composition even possible?
|

Whose work in the 1950s challenged previous ideas about the CO2 absorption rate of the oceans?
|
Roger Revelle
|
|
What did Gilbert Plass establish in the 1950s that was relevant to the science of global warming?
|
Higher levels of atmospheric Co2 would absorb more radiation.

What do you consider some of the most significant evidence of recent unusual climate change?
|
13 of the 14 hottest years were recorded from 1997 to 2010. since the 1850s global averages have risen .76 degrees celsius and .35 over the last 25 years

|
Scientists use air bubbles from ice cores to measure and infer what?
|
Can give you information on how the atmosphere was when that ice was formed. You are able to tell how cold the ice was when it formed.
|
|
Why are CO2 emissions the most signficant of any greenhouse gas?
|
More of it than anything else
