COP21Presentation 4Prediction for the FutureFord & Eric
2 Degree Limit General goal for climate change is to limit
temperature increase to 2 degrees Celsius compared to pre-industrial temperatures
Put into writing at Cancun in 2010
William Nordhaus-1977 Suggested 2 degree limit keeps Earth within natural
range of fluctuation Limits ecological damage because Earth’s
temperature has changed this much before
Currently predicted that we will exceed 2 degrees
2 Degree Limit
If reaching 2 degree limit, by 2100 predictions of altered:
Marine ecosystems
Sea Level Rise
Weather patterns Extreme storms, drought, wildfires
Agriculture Reduction in yields of wheat, rice and corn in
both tropical and temperate regions

YeQ
On a track for
A One Degree Rise
Not analyzing the average air temperature, but the average surface temperature of the earth
Barely perceptible to human skin – but impactful in balance of environment
Scary Fact from Ice Core samples:
In the last million years it has never been more than one degree Celsius warmer than it is now
Solar Geoengineering Study how to reduce solar irradiation
Carbon Dioxide Removal (CDR)
Can we utilize the tech that all trees use We’re not advanced enough yet
Can plant trees But not enough difference would
be made
Solar Geoengineering
Atmospheric Reflection
In 1991, Mount Pinatubo in the Philippines erupted in one of the largest volcanic blasts of the 20th century
Spat 20 million tons of sulfur into the atmosphere Shielding earth from the sun’s rays Causing global temperatures to drop by nearly
a half a degree Celsius in a single year
Volcanic SulfurHalf a degree Celsius is the same amount the
planet has warmed in the last 50 years
Scientists have considered replicating the event to counteract global warming Using a fleet of jets to inject sulfate aerosols
high into the atmosphere to block a portion of the sun’s rays
However, there could be serious unintended environmental consequences Wouldn’t reduce CO2 levels
COP21 Goals
Legal force – provide consequences for not meeting targets
Ensure Green Climate Fund is adequately financed
Differentiation – set goals for all nations, not just developed ones
Focus on adaptation to inevitable climate change
Let negotiations be transparent
Attempt to meet our 2 degree goal
COP21 Predictions
Most experts think that a new international treaty will be signed Update or replacement for Kyoto Protocol Only 32% think it will have legally binding
authority Low confidence in ability to meet 2 degree goal
Ending of subsidies for fossil fuel companies important
Much of the burden will fall on businesses Governments pass their goals along to private
sector
Climate Change Activism
About 570,000 in rallies worldwide Urging change and showing
public support London: 50,000 in march
from Hyde Park to Whitehall
Link to Brandalism movement Reducing the amount of
corporate advertising Showing link between
corporate culture and pollution
