Confronting Climate Change

8232Rosina Bierbaum, formerly of President Obama’s Council of Advisors on Science and Technology (PCAST) and an Adaptation Fellow at the World Bank, shows how climate change will affect all regions and sectors of the economy, and disproportionately affect the poorest people on the planet. Therefore, improving the resilience, adaptation, and preparedness of communities must be a high priority, equal to that of achieving deep greenhouse gas reductions and rapid development and deployment of innovative technologies, as well as altered planning and management strategies in the coming decades to achieve a sustainable world.

Climate Change Hasn't Changed

In “An Inconvenient Truth,” Al Gore presents his case on climate change based on the “Keeling Curve,” measurements of the increasing levels of carbon dioxide (CO2) in the atmosphere.

These first records of rising CO2 levels were taken in the 1950’s by Charles David Keeling of UC San Diego’s Scripps Institution of Oceanography.

Even then scientists were aware of the green house effect created by CO2 in the earth’s atmosphere.  Keeling tracked the increasing levels of CO2 for decades, but it didn’t take long for him to link the rising CO2 levels with the burning of fossil fuels. Although it was known that the burning of fossil fuels created CO2, it was widely believed that the ocean absorbed all of that excess carbon dioxide. Keeling was the first person to prove that CO2 was accumulating in the atmosphere, as it still is today.

In “The Scientific Case for Urgent Action to Limit Climate Change,” Distinguished Professor Emeritus Richard Somerville of the Scripps Institution of Oceanography presents a case based on some of the initial measurements of CO2 in the atmosphere taken by Keeling.

In this video, Somerville further explains this research and his ideas for how to reduce the emissions causing climate change. If you want more information on climate change and ocean science, check out the “Perspectives on Ocean Science” series.
