Which of the following events could increase Earth's temperature?
A. a decrease in the relative percent of greenhouse gases
B. planting more trees
C. widespread removal of tropical forests

D. a reduction in the use of fossil fuels

[bryjones71]

c will lead to increase in a
trees are the lungs of the planet.. obviously if we are not producing as much oxygen, in time the percentage of the other gasses + green house gasses will go up + where do trees get there carbon from?... rainforest's.....are the best stabiliser for the infotainment in he long run.

I'm just curious is this a homework assignment? If so for what grade. Do you go to Al Gore HS? This is the most blatant push of propaganda I have seen. Why cant schools just give the facts and let students form their own thoughts? This is not against you the asker. I weep for the future.

C

A would decrease heat trapping and hence lower temp

B, actually depends where. Trees themselves can absorb more sunlight than snow or bright desert, but trap CO2 as they grwo.

D - as for A

Chiefwaz, I also weep for the future, but with better reason

With over 90% certainty, global warming is real, serious, unprecedented, driven mainly by human activity, and requires appropriate action.This conclusion is reached even after taking natural variation, such as that connected to the sunspot cycle, into account. See statement at

endorsed by the [US] National Academy of Sciences, Chinese Academy of Sciences, Indian National Science Academy, , Russian Academy of Sciences, Royal Society (London). Over 40 other academies of national stature have issued similar statements:

This view is based on thirty years of watching the evidence accumulate. Look in SCIENCE or NATURE, or even references in Wikipedia Global warming, for extensive real peer-reviewed scientific research.

There is a lot of disinformation out there, and a lot of fossil fuel money being spent to push it. All too successfully, to judge from YA

I pretty sure it is A. it might be D. though but i would go with A. and the weird thing is i learnd this today in class so it is 99.9%right
