Arctic ecosystems are particularly sensitive to human-induced climate changes because of how rapidly they are warming due to Arctic amplification 1. Climate model simulations, based on optimistic scenarios in which atmospheric carbon dioxide concentrations peak mid-century at ~550 ppm (RCP4.5), predict that summer near-surface air temperatures in the Canadian Arctic will increase by 3.2 °C by 2100, relative to 1986–2000 temperatures 2. In the most northerly reaches of Canada on Northern Ellesmere Island, there has already been an ~1 °C increase in summer air temperatures during 2001–2012 relative to the 1986–2000 reference period 3. These climate changes have potentially important consequences for Arctic ecosystems and, yet, there is a complete paucity of studies that document ecosystem-scale climate tipping points for inland watersheds. In fact, two recent syntheses emphasized the need for ecosystem-scale studies that integrate physical, chemical and ecological processes to better understand the climate–hydrology–biogeochemistry linkages that lead to ecosystem shifts 4, 5.

Fred was known for his roles in films such as The Right Stuff, Short Cuts and Tremors. A statement to the New York Post by the actor's representatives said that he died on 8 May. Katherine told Glamour, "We four Townsend girls competed about everything. Grades. Sports. Who could be loudest at the dinner table." Toughness is clearly in their genes. Their mother, Kathleen Townsend told The Atlantic about birthing three of her girls at home. When she was in labor with Katherine, she walked about the house and even watched the entire film version of Taming of the Shrew. Kathleen told The Atlantic, "I liked Elizabeth Taylor's character so much that I decided to change my new daughter's first name from Rose to Katherine."

Perren, B. B. et al. Twentieth-century warming revives the world’s northernmost lake. Geology 40, 1003–1006 (2012). ABC World News anchor David Muir will lead the network’s coverage of the climate conference, joined by chief White House correspondent Cecilia Vega and foreign correspondent Maggie Rulli. President Biden and former President Obama are slated to attend. Muir will also report from Madagascar, the island nation that the World Food Program says could be the first place to see a climate change-induced famine. ABC says Muir will be the first American journalist to access southern Madagascar through the World Food Program. What we witnessed is truly catastrophic. You can see the desperation in the faces of the children,” Muir tells The Hollywood Reporter. “Madagascar is facing the first famine driven entirely by climate change. There is no war, no terror, no political conflict driving this. More than a million people are already facing acute hunger. The world needs to see this.”

The result was special for Williams, who was joined on her lap of honour by her two-year-old son Zuri. “That is the first time he has been out on a big stage but there will be many more,” she said. I am sad to announce the passing of acclaimed actor Fred Ward, who passed away on Sunday, May 8, 2022, at age 79,” the statement read.

Ohuruogu, the younger sister of the Olympic and world champion Christine, was delighted to win the first major medal of her career after a few years in the wilderness. “It took me quite a few years to get over the pressure of my sister and I don’t know if it’s too late but now I am coming into my own,” said the 29-year-old, who set a personal best of 50.72 to take the silver medal.

I will always remember chatting about his love of Django Reinhardt and jazz guitar during our long, hot days in the high desert. Rest In Peace Fred." So sad to hear of his passing," another follower wrote, while another commented: "Can't believe it. So sad. May he rest in peace." A third replied: "This one hurts," alongside a crying face emoji. Not that McColgan, who ran 14:42.14 to finish four seconds behind Chebet, minded. “It’s just been an absolute rollercoaster of emotions since Wednesday,” she said. “Every time I went to the dining hall, I’m just crying because it’s just amazing. I was so tired, mentally and physically but I’m so proud of myself.”
