Our Latest Presentations
Upcoming Presentation
November 10, 2026
On November 10 at noon, ESF will host Andreas Schmittner. Andreas is a professor at Oregon State University and he will tell us about Climate Change Effects on our Oceans. The Zoom link is below.
Speaker: Andreas Schmittner
Andreas is a scientist interested in Earth’s climate system. Most of his work is focussed on the oceans, their physics, biology, chemistry and variability on decadal to millennial time scales.He studies the causes for today’s global deep overturning circulation, how and why it has changed in the past, how it may change in the future due to natural or human influences, how it impacts climate, ecosystems and biogeochemical cycles including isotopes.
Presentation: Climate Change Effects on our Oceans
Scientific evidence will be presented that describes how climate change affects our oceans. Human emissions of carbon dioxide into the atmosphere lead to warming and acidification of the upper ocean. Observations document both effects conclusively. Warming is expected to affect the solubility of gases such as oxygen and carbon dioxide. Warming, declining oxygen concentrations, and increasing acidification will affect ecosystems. Global warming also leads to changes in the water cycle, which affects the salinity of sea water and its buoyancy. The resulting increases in stratification will reduce convection and the global overturning circulation of the ocean, with the potential of abrupt changes. Andreas will discuss evidence from paleoclimate and modeling that illustrate effects of possible circulation changes. Melting of ice and warming also impact sea level, which is already rising and projected to accelerate in the future. The degree to which these effects will continue depends on the amount of future carbon emissions. Reducing emissions will mitigate the effects. Nevertheless, we will also need to adapt to those changes that are unavoidable. Solutions to climate change must be based on reducing carbon emissions.
