The latest thing climate change is threatening is our history

The old city of Dubrovnik, clinging to the Croatian coast of the Adriatic Sea, is one major storm away from a flood that could cover 10 percent of a medieval city long known as the “Pearl of the Adriatic” and more recently as a main setting for HBO’s “Game of Thrones.”

It’s one of about 40 treasured historical sites across the Mediterranean, including the winding canals of Venice and the ancient city of Carthage, at risk from rising seas, according to a study published Tuesday in the journal Nature Communications.

The reason for their sweeping vulnerability is the same one that fostered so many civilizations in the Mediterranean to begin with. It’s the lure of the sea, dating back at least to the time of the ancient Phoenicians, who set sail from the now-threatened sites of Byblos and Tyre along the current coast of Lebanon.

Global warming will weaken wind power, study predicts

Wind farms are key to tackling climate change but warming will significantly cut the power of the wind across northern mid-latitudes, including the US, the UK and the Mediterranean, according to new research. However, some places, including eastern Australia, will see winds pick up.

 In central US, the power of the wind could fall by nearly a fifth. 

The research is the first global study to project the impact of temperature rises on wind energy and found big changes by the end of the century in many of the places hosting large numbers of turbines.

Wind farms have grown more than fivefold in the last decade and plunging costs have made them a key way of reducing carbon emissions from fossil fuel burning. But in the central US, for example, the power of the wind could fall by nearly a fifth.

“We found some substantial changes in wind energy,” said Kristopher Karnauskas at the University of Colorado Boulder, US. “But it does not mean we should not invest in wind power.” It does mean such changes need to be taken into account in planning future wind farms, he said, and also in assessing how much wind farms overall can cut global emissions.
