Possible gulf-stream collapse

There are a group of people who think they've discovered that Climate Change is a cooked up idea to sell papers or allow big business to make billions. 97% of climate scientists agree with the evidence that climate change is man made. Possibly the other 3% agree that the world is flat, who knows.

Ice ages are cyclical and occur every 75,000 to 100,000 years. We're in an interglacial right now, and the changes we are observing now in our climate have happened over a period of about 50 years. This isn't natural smile.

I've been hearing these scare stories for decades too. There were a whole lot of things that were forecast to be tipping points, things that once they happened we'd know for sure there was climate change and that we were causing it. Melting permafrost in Siberia; break up of the Larsen B ice sheet; reduction is size of the Arctic winter ice coverage, for 3. Guess what? All happened. The Gulf Stream is probably next.

When the poles change, we'll have a period of time when communications will be affected and the homing pigeons might get a bit confused. Solar radiation will be higher and so there will probably be higher rates of cancer for a while, we should anticipate that. The aurora will be spectacular. Other than that, I think we'll be fine. Provided we can dodge the wildfires. droughts, food crises and flooding the climate change will have brought, of course.

Eating breakfast right now. Climate change deniers will be addressd shortly.

Algerias1. I have been reading these scare stories for years. Usually rolled out in the summer months to sell papers.
The climate is changing, always has, always will. How much is anthropogenic remains to be seen.
Glasgow was under ice fairly recently (in geological history) yet we have the remains of a Carboniferous Tropical rainforest in a city park.
Anyone want to place bets on the next big scare story?
My money is on magnetic pole reversal. The earth is long overdue for one. Just think of the devastation a sudden pole reversal will cause………….

Seagar's work questions whether the shutdown of the gulf stream would have the effect of making the climate in the UK and the rest of Europe abruptly become like that of Canada, for example.

The Guardian article covers research that shows the Gulf Stream is close to collapse, and that will affect the climate of the entire world, possibly irreversibly.

You won't have a frozen Thames, but you might have unprecedented flooding in summer, more uncontrollable wildfires around the world.....sound familiar?

The Guardian is not usually sensationalist so this does give pause for thought.
People glibly joke about “Mediterranean summers” and global warming, but climate change is very real and very alarming.

Get the winter woollies out of the loft then?

We won’t have to worry about global warming then, temperatures equivalent to Newfoundland will be very unwelcome. So we will all have to migrate to warmer climes or adapt, more extremes of weather are very likely in years to come.

May I suggest that before getting over excited about a newspaper article you read Richard Seager’s presentation to the New York Academy of Science entitled “Climate Mythology: The Gulf Stream, European Climate and Abrupt Change”.

I think the best thing we can all do is to just do our best to be good environmental citizens. I refuse to fret over something I have no further control over than that. The earth has always undergone significant and massive changes.

I find this terrifying.
