Ocean Current That Keeps Europe Warm Is Weakening Because of Climate Change (washingtonpost.com)
The Washington Post: The Atlantic Ocean circulation that carries warmth into the Northern Hemisphere's high latitudes is slowing down because of climate change, a team of scientists asserted Wednesday, suggesting one of the most feared consequences is already coming to pass (Editor's note: the link may be paywalled; alternative source). The Atlantic meridional overturning circulation has declined in strength by 15 percent since the mid-20th century to a "new record low," the scientists conclude in a peer-reviewed study published in the journal Nature. That's a decrease of 3 million cubic meters of water per second, the equivalent of nearly 15 Amazon rivers.
The AMOC brings warm water from the equator up toward the Atlantic's northern reaches and cold water back down through the deep ocean. The current is partly why Western Europe enjoys temperate weather, and meteorologists are linking changes in North Atlantic Ocean temperatures to recent summer heat waves. The circulation is also critical for fisheries off the U.S. Atlantic coast, a key part of New England's economy that have seen changes in recent years, with the cod fishery collapsing as lobster populations have boomed off the Maine coast.

There is no "cooling trend". The current as it is today provides anomalously warm temperatures to northwestern Europe. If this current is fully disrupted, the UK and friends will end up having the same general climate as northern Canada. Along with northen Canada, it then will slowly warm in accordance with the generally accepted global rates.
You are in a twisty maze of processor lines, all alike.
There is a lot of hype here.
Paris accord will solve all the issues with Climate Change. I am sure that if we do not focus on stopping growth in emissions, and instead all focus on per capita emissions while allowing CHina, India, Brazil, South Africa, etc to grow, that it will solve all of these issues.
I mean what could possible go wrong with stopping 1 small group of ppl while allowing others to grow far bigger in their emissions.
I prefer the "u" in honour as it seems to be missing these days.
The sad truth is most folks don't realize how fragile our planet is, it's a finely balanced chaotic system where a slight change in something as small as the CO2 concentration in the air is enough to cause a massive shift in climate. Nature normally takes thousands of years but we're essentially speeding it up into centuries or even decades. It's been known for years that the ocean sea currents could change with climate change and unfortunately it looks like it's coming true. If the oceans current shutdown it won't just cause Europe to get cooler. It could disrupt the monsoon rains which allow India to farm and provides water. If you have a billion people starving to death, I wouldn't want to explain to them how this wasn't my fault and I'm not sharing.
