A natural environment that absorbs and stores more carbon dioxide from the atmosphere than it releases, which offsets greenhouse gas emissions.
A nutrient (such as sugar) that provides carbon skeletons needed for synthesis of new organic molecules (anabolism).
the ongoing decrease in the pH of the Earth's oceans, caused by the uptake of carbon dioxide (CO2) from the atmosphere.
The problem caused by increased quantities of gases such as carbon dioxide in the air.
water vapor, carbon dioxide, methane, nitrous oxide, ozone, CFCs, HCFCs
a natural fuel such as coal or gas, formed in the geological past from the remains of living organisms.
The total amount of greenhouse gases produced to directly and indirectly support human activities, usually expressed in equivalent tons of carbon dioxide (CO2).
Range of tolerance
An upper limit and lower limit that include the zone of physiological stress and optimal zone in which an organism can survive
environmental pollution and pollutants originating in human activity
It is tracked by ships, stations, and satellites
How is earth's atmosphere tracked?
0.8 degrees Celsius or 1.51 degrees Fahrenheit
How much has earth's temperature already risen? F? C?
bushfire, droughts, and black Christmas that consisted of many fires
How has an increase in global temperatures affected Australia over the past decades?
Melting of Arctic sea ice that opens northwest passage, homes around Bay of Bengal will be flooded, hurricanes occurring in South Atlantic, and severe droughts in western U.S.
Identify 3-4 events that will occur if we reach 1 degree Celsius
383 ppm of CO2 and is dangerous at 450 ppm
How many ppm of C are currently in the atmosphere? What is considered the 'dangerous level'?
What % of the world's energy starts as fossil fuels?
greenhouse gases would disappear, polar bears would struggle to survive and insects would migrate to new places, new forest in Canada's tundra and most coral reefs would die.
If the planet reaches 2 degrees Celsius hotter, describe the events that will occur
It can acidify the ocean and causes bleaching in coral reefs. The organisms in the ocean die and lose their habitats from the excess CO2 in the ocean.
Describe how additional C affect oceans. How does this process effect the organisms living in the ocean?
86 degrees Fahrenheit. When the temperature extended that, the corals began expelling algae and that caused bleaching events and corals' death.
What is the temperature tolerance range for Australia's Great Barrier Reef? What happened when the temperature exceeded that level?
150,000 years. 7 meters
How long did it take to make the ice sheet covering Greenland? If it melts how much will sea level rise?
Moulins are huge tunnels under Greenland's glaciers where melted water flows under the glacier. The significance of moulin is that it lubricated the bedrock or the foundation of the glacier causes the ice to melt faster
What is a moulin and what is their significance in Greenland glaciers?
37.4 degrees Fahrenheit. The Arctic will be ice-free for the entire summer and the Amazon rainforest would dry out and the Alps snow caps would disappear, and the Mediterranean get serious heat
If global temperatures approach 3 degrees Celsius, what is that temp. in Fahrenheit? What are the effects of this temperature on global climate?
There were heatwaves in Europe that cause the elders to have heat strokes. 2500-3000 Parisians who died. 30,000 people in Europe died
What happened to Europe in the summer of 2003? How many Parisians died? How many Europeans died during this summer related to heat stroke?
Vegetation releases carbon dioxide instead of oxygen
What happened to vegetation as temperatures approach 3 degrees Celsius?
A drought that made the river dry
During the summer of 2005, what did the Amazon region experience that has never occurred before?
Vegetation will fail due to drought and the C would get released which intensify global warming
If the Amazon region dies, what will happen to the vegetation? To the stored C?
A violent weather anomaly and it affects trade winds by weakening it and changes its direction completely
What is El Nino and how does it affect trade winds?
Powerful and destructive storms that affect an unusually large area. They develop by the warming of the ocean
What are superstorms and how do they develop?
39.2 degrees Fahrenheit. The ocean rise and flood lands and Bangladesh will be washed away, glaciers disappear, and many people will suffer from water loss. Northern Canada will be used for agriculture and the Arctic ice sheets will collapse
If the global temperature reaches 4 degrees Celsius, what is this temp. in F? What are some global effects of temperatures this high?
It has the largest storage of fresh water in glaciers for plants
What is the significance of the Himalayan mountains?
barriers for floods and huge sea gates
What have some industrialized cities constructed to prevent severe storm urges?
5- 2 massive inhabitable zones in the southern and northern hemispheres that were once temperate zones while snow caps and aquifers that supply fresh water will dry out.
6- the ocean will be wastelands and there will be plenty of deserts spread around the globe as long as natural disasters will occur frequently
What are some of the predictions for 5-6 degrees global warming?
To eliminate vampires loads from household appliances
What is the safest, fastest, easiest way to save C emissions in the world?
We need to cut seven billion tonnes of C emissions every year
How many tonnes of C emissions need to be cut every year to stay below the 2 degrees mark?
They don't know how terrible things can get and hope to never find out
What 2 things do all climate scientists agree on?
