COP21: Policy strategies beyond CO2 emission targets

Based on the current trajectory of human-induced impacts on the environment, it is clear that we are pushing the oceans and marine ecosystems to unprecedented limits. Environmental changes in ocean properties have led to an array of ecological responses, from shifts in the composition of the ocean’s phytoplankton to changing distributions of fish species.

COP21: Where have all the fish gone? How climate change is displacing marine species.

Climate change could affect temperatures all over the world, but what may not be immediately apparent is that climate change will affect ocean temperatures. If CO2 emission rates do not change, the average sea surface temperature is expected to increase by 2 to 3.5 degrees Celsius by the end of the century. This may not seem like much, but it would impact oceans in many ways, making them quite different from how they are today.

Rebecca Asch gives lecture on climate change and seasonality in the oceans

Climate change is resulting in the earlier arrival of spring conditions in many ecosystems around the world. Rebecca Asch, Nereus Fellow (Princeton), gave a lecture at Wellesley College, USA, on November 13 entitled “Climate Change and Seasonality in the Oceans: How will Changing Seasonal Cycles Affect Marine Food Webs?” This was an invited talk sponsored by the Department of Biological Sciences.
