Trump on recent climate change report "I don't believe it"

Ocean circulation in North Atlantic is at its weakest for 1,500 years - and at levels that previously triggered a mini Ice Age, study warns

Study shows the levels are at their lowest for 1,500 years

Currents have a 'profound effect' on both North American and European climate

Researcher found a similar weak signal during a period called the Little Ice Age, a cold spell observed between about 1600 and 1850 AD

wrong, you should study a little

core samples from tidal basin indicate many things, including temperature, PH, primary direction of currents etc…

>How did these modern researchers discern what the currents were doing with any statistical accuracy with no instrumentation in place to measure these currents in 1600-1800 AD?

it's called a core sample

by drilling into the tidal basin and carefully measuring the qualities of the sediments extracted

pretty settled science actually

they do core samples of

Ice from glaciers

Soil from lake and ocean floors

Soil from archeological sites

Trees it's called dendrochronology in that case

>Studying sand =/= studying fluid dynamics.

are you saying prevailing current flow has no effect on particle orientation in the sediment layers?

>but I don't believe it, never will.

it's your prerogative to remain ignorant
