Climate change is, first
and foremost, a consequence of the addition of carbon dioxide into the
atmosphere. We emit carbon dioxide, through burning fossil fuels or forests, and
some of that carbon stays in the atmosphere, intensifying the heat-trapping greenhouse effect and
warming the climate. What kind of global warming we’ll see in
the future will largely be due to how much carbon dioxide—and to a lesser
extent, other greenhouse gases like methane—we add to the atmosphere. And to
fully understand the future, we need to understand the present and the past, and
track the concentration of CO2 in the Earth’s atmosphere.

THERE IS NO GLOBAL WARMING. EARTH GOES THROUGH THESE CYCLES EVERY THOUSANDS OF YEARS. THIS IS ALL JUST MEDIA HYPE.
ReplyDeleteGaurav i completly disagree and this is a serious topic that we need to fix
ReplyDeleteI disagree with Curran, if you look at statistics, you can see that Earth is actually in one of its coolest periods in several thousand years. In fact, in the 1970s, people feared "Global Cooling", so it is not a man-made phenomena, it is just a natural weather cycle.

DeleteI disagree with Gaurav and Lorenzo. Even though these cycles occur every thousand or so years, you can not deny the fact that pollution is having an effect on the increase of temperature. We cant just sit at home and say global warming is not happening but wouldn't it be more reasonable to find ways to stop all the pollution and take action so we know for sure that our world can be safe for our children and their children to come?
Polution only contributes a little, theres nothing we can do to actually stop it. We can only stop it by a miniscual percenatge. Go do some research.
Deleteyeah and gaurav if everyone does a lot we can stop it by a bigger precent and show me that link of the research you did
