Climate change and Green house effect
what does the abundance of greenhouse gasses do in the atmosphere?
contributes to global climate change
how is the earth's greenhouse effect different than an actual green house on earth?
greenhouses will always hold up in the heat
what is the greenhouse effect?
natural occurance on earth atmospheric gases hold in heat
what are the 9 pieces of evidence that our climate is changing rapidly?
Global temp rising warming oceans shrinking ice sheets glacier retreat decreased snow cover sea level rise declining artic sea extreme events ocean acidification
what are the two ways the earth heats up?
absorption of sun's energy by land and water energy by clouds and atomospheric gases
what tool has enabled scientists to collect data on a global scale?
satellites
what is a vital sign for Earth's climate health?
temperature
What does CO2 do to heat in the atmosphere?
traps it
what are common atmospheric greenhouse gasses?
water vapor -responsible for 60-70% of atmospheric greenhouse effect -with global warming, more evaporation of water will occur creating an increase in water vapor in atmosphere - will increase green house effect carbon dioxide/ methane
abundant greenhouse gases
water vapor carbon dioxide- burning of fossil fuels methane-ch4-cows ozone-smog cfc's- man made
5 heat trapping gases that contribute to the green house effect?
water vapor nitrous acid carbon dioxide methane chloroflurocarbon
