Climate Change: 9/9, Mark Cane

Climate changes occur with rapid, unexpected transitions and they will affect the way humans live and die.

Temp increase correlates with a rise in the CO₂ in the atmosphere

Using data on current and historical atmospheric CO₂levels, scientists try to establish models of what the future of climate change will be and the possibility of different ecological happenings.

These models aren’t as accurate as we would hope because of their lack of sensitivity, and the many different factors that can’t be accounted for.

Current levels of Greenhouse Gases through pollution are increasing the rapidity and uncertainty of climate change.

Other points made: El Nino, connection between climate and health (heat related deaths)

Energy Utilization: 9/9, Klaus Lackner

Energy is a problem, but also a necessity that leads to pollution, namely CO₂emissions. We cannot stop using fossil fuel due to economic reasons, so we must contain and dispose of the CO₂ to achieve a zero emission state.

Only 14% of energy used is from renewable sources.

Use of fossil fuels releases 6.5 billion tons of CO₂ per year that cannot all be absorbed into carbon sinks.

We must

achieve zero CO₂ emission energy production

pull current high levels of CO₂ out of the atmosphere
