chemistry of the atmosphere - climate change Flashcards
(11 cards)
why is carbon dioxide increasing
as we are burning more fossil fuels
how is carbon dioxide absorbed
by growing trees e.g. those in tropical rainforests
what does burning forests do
release lots of carbon dioxide
how is methane released
by growing agriculture e.g. paddy fields or by cattle passing wind
why does more carbon dioxide and methane cause an increase in temperature
because more of the energy from the sun is trapped
what are the possible effects of climate change
- ice melting, increasing sea levels leading to higher risk of flooding
- more serve weather
- change in distribution of animals and plant as well as microorganisms
what do many scientists believe climate change is caused by
human activity
why is this
the evidence is shared between many different scientists
what does peer review allow for
detect false claims
what is a problem with understanding climate change
its completely and difficult to model - media stories may be simplified or biased
what are some uncertainties towards climate change
we cannot predict with certainty how much the temperature of the atmosphere will rise
