I think we are all familiar with the implied causal relationship between Climate Change and rising sea levels. President Obama famously said in 2008 “this was the moment when the rise of the oceans began to slow and our planet began to heal,” injecting the topic in to his first presidential campaign.
A recent report in Geophysical Research Letters seems to have caught even the climate and geophysical community off guard. It reports that pumping ground water, for aquaculture or other purposes, contributes to perceived rising sea levels more than actual sea levels rising due to changing climates.
The take home message; systems as complex as global climates can’t be reduced to simply carbon emissions and expect that predictions based on these assumptions will be even remotely accurate.
