NewYork (AFP): A bronze sculpture by Swiss artist Alberto Giacometti valued at more than $100 million and 20 works by pop art icon Andy Warhol headline New York’s fall art auction season next week. Art worth at least $1.7 billion from impressionist and modern; post-war and contemporary go under the hammer at Christie’s and Sotheby’s at combined evening and day sales from November 4 to 12. The most expensive lot under the hammer is Giacometti’s 1950 “Chariot,” the highlight of Sotheby’s impressionist sale on Tuesday. WASHINGTON (AFP): US Secretary of State John Kerry said Sunday that those who ignore climate science do so at a risk to future generations, as UN experts unveiled the final chapter of a landmark climate report. “Those who choose to ignore or dispute the science so clearly laid out in this report do so at great risk for all of us and for our kids and grandkids,” Kerry said. “The longer we are stuck in a debate over ideology and politics, the more the costs of inaction grow and grow.”
