Last week when I was in Copenhagen I saw a presentation from Katherine Richardson from the University of Copenhagen (Denmark). She gave a really interesting presentation about how global warming changes the oceans and vice versa. Ocean waters now cover nearly 71 percent of Earth’s surface. Did you ever wonder how the oceans influence our environment and climate? Did you know that there is a constant exchange of gases between the ocean and atmosphere? About 50% of the “extra” CO2 released to the atmosphere from human activities is now found in the ocean. Thus, the ocean acts as a buffer with respect to the pace of global warming. This increase in CO2 is changing ocean chemistry and biology and it is not certain that the ocean will continue to take up CO2 in the future at the same rate as in the past.
You can watch the video of the presentation here The actual presentation starts at 21 minutes, the really interesting part starts en 34 minutes. Interesting is that in the end she proposes to tweak the eco system, in order to reduce the amount of OC2 in our environments. Is that really possible?
