Climate models fail to predict air pressure shift above Greenland, Changes

There are changes in weather and so is the need to adapt to it.
Water levers are raising and so hurricanes are flooding worse.
Heat will rise also along with crops not doing well in 119 deg
weather in the south full of stupid hot! Global warming is a issue
to crops that makes a issue to us with no food to eat!

But as a warning we all should be noting the changes going on
and act accordingly!

~~~~~Climate models fail to predict air pressure shift above Greenland
"We think that the recent rapid warming over Greenland since the early 1990s is not being fully simulated by the models," said researcher Edward Hanna.

Climate models failed to predict air pressure changes measured in the atmosphere above Greenland over the last few decades. According to a new study, the failure undermines the reliability of climate models for regional predictions in the North Atlantic.

Over the last few decades, Greenland has experienced an increase in summertime air pressure, a phenomenon called "Greenland blocking." Climate models, however, predicted a slight decrease in air pressure during the same time period.

If air pressure continues to increase across Greenland, climate scientists think the British Isles are likely to experience an increase in summertime precipitation -- a likelihood missed by current climate models.

Scientists think North Atlantic climate predictions are underestimating the region's accelerate warming, as well as the impacts of Greenland's melting ice sheet on global sea level rise.

"While there is natural variability in the climate system, we think that the recent rapid warming over Greenland since the early 1990s is not being fully simulated by the models, and that this misrepresentation could mean that future changes in atmospheric circulation and the jet stream over the wider North Atlantic region may not be properly simulated," Hanna said.
