re: Ocean currents are collapsing due to climate change.

You can find a lot more info on it searching Irish news because the Gulf Stream has a much bigger impact on their weather than other places. This isn't new to them, they've been discussing it for years.

The researchers from Ireland, Britain and Germany have compiled data taken mainly from natural archives in the form of ocean sediment or ice cores – going back hundreds of years – to reconstruct the flow history of the Gulf Stream. They found consistent evidence its slowdown during the 20th century is unprecedented in the past millennium. The giant ocean circulation has an impact on the climate of northwestern Europe.

Previous studies showed a slowdown of the ocean current of about 15 per cent since the mid 20th century, “but a robust picture about its long-term development has up to now been missing. This is what the researchers provide with their review of results of proxy data studies,” he said.

"Instead of relying just on one data set, we used a combination of several different and largely independent proxy indicators to reconstruct the evolution of the Amoc over the past 1,600 years," said lead author Levke Caesar of Icarus climate research centre in Maynooth University.

The data indicate the Gulf Stream was relatively stable until the late 19th century. With the end of the little ice age in about 1850, the system of ocean currents began to decline, with a second, more drastic decline following since the mid-20th century.
