COP21 Presentation 4 Prediction for the Future Ford & 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 2 Degree Rise Video https://www.youtube.com/watch?v=P0_gDXqYeQ 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 Sulfur Half 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 Sources http://www.bbc.co.uk/news/world-34956825 http://www.sustainability.com/news/expertsconfident-that-cop21-will-lead-to-an-internationalagreement-predict-that-business-will-be-key-to-itsimplementation-post-2015#.VluX9fnhDtQ http://www.theenergycollective.com/falwellp/219 3591/core-issues-paris-climate-talks
