However, the causes of this are unknown. There's some correlation between greenhouse gas emissions and increased temperatures, but it's hardly for sure. As we all know, correlation is not cause. There are plenty of possible natural causes for something like this. The sun's energy output varies and even the smallest fraction of a change could yield large increases in temperature. The temperature has fluctuated throughout earth's history.
Basically, there has been a ridiculous rise in greenhouse gas emissions, and people are scared because of the potential for major problems. Nothing's conclusive up to this point, though.
Likely cause for snowing in Baghdad: El Nino. It affects different areas in different ways and uncharacteristically cold weather is not too uncommon. |
cool! there's AP Environmental Science. good for our future. and yeah... it's been too long since i was in high school.
speaking of conclusive, at some point you just need to make a "call" . at this point, i, being practical, think it's good enough to make a call.
