Dinosaurs died from sudden temperature drop 'not comet strike', scientists claim

British researchers claim that a sudden plummeting in the sea temperature of 16F (9C) more than 137 million years ago was the first step towards their eventual road to extinction.

While studying fossils and minerals from the Arctic Svalbard, Norway, they concluded the sudden change in the Atlantic Gulf Stream during the Cretaceous period would almost certainly have wiped out the ''abundance'' of the world's dinosaurs.

Some experts believe the creatures were wiped out by one cataclysmic event 65 million years ago – such as a meteor hitting the planet.

But the new research suggests they were wiped out by a series of environmental changes, starting with a drop in sea temperatures.

Gregory Price, from Plymouth University, who led the study, said his team's research showed the drop in temperature happened when the Earth was in a ''greenhouse'' climate, which was very similar to now

So it looks like we are still pretty much confused about what happened 65 million years ago as this Interesting article claims that the dinosaurs didn't die out from a comet strike after all.
but more to do with climate change which they say is similar to what we are experiencing now.

So is it just me or Is this not just fear mongering telling people that the greatest extinction in history happened because of conditions that are becoming similar to what we are in right now.

It just sounds like a great opportunity to keep peoples mind on the climate changing still.

Anyway the article goes on to say that they believe the dinosaur’s died out gradually rather than in one clean swoop and this quoted below.

The drop in temperature is thought to have occurred because high levels of CO2 were in the atmosphere which caused global temperatures to rise and polar ice to melt – a phenomenon currently predicted for Earth.

Oh crap!
Day after tomorrow stuff all over.
Time to take igloo building 101 again.
