Earth911 Quiz #94: Climate Change, Trees, and Carbon Sequestration
The U.N. Intergovernmental Panel on Climate Change’s sixth report on the state of the worldwide local weather raises a purple flag for humanity and gives a variety of options to lowering the degrees of CO2 in Earth’s ambiance. In this Earth911 Quiz, you’ll check your primary understanding of local weather change, a number of methods we will seize and retailer carbon, and the timeframe during which we will count on to see constructive modifications within the surroundings from the efforts we make immediately.
How a lot human-generated CO2 is emitted into the Earth’s ambiance yearly?
Since the daybreak of human civilization, people have been contributing CO2 to the ambiance, however it was solely with the appearance of industrialization within the late 18th century that CO2 ranges have accelerated quickly. Now, people produce extra CO2 and different environmental impacts than the planet can course of — since 1970, folks have exhausted Earth’s capability to take away CO2 earlier yearly. How many gigatons (a billion tons) of CO2 do folks pump into the surroundings yearly in comparison with pre-industrial instances?
How a lot has the Earth’s common temperature risen for the reason that starting of contemporary industrial society?
There is a confirmed direct correlation between atmospheric CO2 ranges and international common temperatures. While some components of the globe, notably the Arctic, are warming sooner than the remainder of the planet as a result of CO2 traps photo voltaic power, which is then absorbed by the oceans which acts like a thermal battery that can proceed to warmth the planet extra, the worldwide common temperature has climbed alarmingly. How a lot hotter is common temperature than in 1850?
How a lot CO2 can one trillion bushes seize and retailer in a yr?
Planting bushes to seize and sequester CO2 is one in all a number of essential responses to local weather change that may be put in place. A single mature tree can seize as much as 48 lbs. of carbon dioxide yearly, although the precise quantity will differ primarily based on the kind of tree, the native local weather, and different elements. If people plant 1 trillion bushes, what number of tons of CO2 would this new forest seize yearly, and the way lengthy wouldn’t it take to take away the present carbon overload within the ambiance?
