Seafloor Discovery Shows The Ocean's Undergoing a Change Not Seen in 10,000 Years

PETER T. SPOONER, THE CONVERSATION 1 MAY 2020

Changes in ocean circulation may have caused a shift in Atlantic Ocean ecosystems not seen for the past 10,000 years, new analysis of deep-sea fossils has revealed.

This is the striking finding of a new study led by a research group I am part of at UCL, funded by the ATLAS project and published in the journal Geophysical Research Letters. The shift has likely already led to political tensions as fish migrate to colder waters.

The climate has been quite stable over the 12,000 years or so since the end of the last Ice Age, a period known as the Holocene. It is thought that this stability is what allowed human civilisation to really get going.

In the ocean, the major currents are also thought to have been relatively stable during the Holocene. These currents have natural cycles, which affect where marine organisms can be found, including plankton, fish, seabirds and whales.

1. i am expecting climate change is gonna fuck up currents too.

2. Problem is though the climate is always changing so imo rather than bitch about it we should be

focusing all our efforts on other things.
For example things like new and better ways of doing some of the things we do like producing energy or manufacturing but in a way that reduces the amount of pollution we produce to as low as we can honestly get it.
Other thing is changing how we build houses and other structures as we need more cost effective ways that are truly as environmentally friendly as we can make it and we should keep striving to do better on all of that.

3. not enough to alter the gulf stream etc. already fucked up the jet steam.

its coming i bet.

4. Those things are part of the earth and that is always in the process of change.

What we need to do is learn to adapt to any of the changes that might occur because if we fail to do that we will not last long as a species.
