Alaska sees record temperatures in heatwave

The US state of Alaska, part of which lies inside the Arctic Circle, is sweltering under a heatwave, with record temperatures recorded in several areas, including its largest city.
Temperatures reached 90F (32C) in Anchorage on Thursday, shattering the city's previous record of 85F.
Several other places in southern Alaska also set all-time or daily records.
Experts say the unusual weather has been caused by a "heat dome" over the southern part of the state.

The high pressure system is expected to move north next week.

Climate change: Trees 'most effective solution' for warming - BBC News

Researchers say an area the size of the US is available for planting trees around the world, and this could have a dramatic impact on climate change.
The study shows that the space available for trees is far greater than previously thought, and would reduce CO2 in the atmosphere by 25%.
The authors say that this is the most effective climate change solution available to the world right now.

But other researchers say the new study is "too good to be true".

CO2 emissions are set to exceed 1.5 degrees of global warming | Science News

Current and planned energy infrastructure could emit around 850 gigatons of the greenhouse gas.
A new study shows just how hard it may be to limit global warming to 1.5 degrees Celsius over preindustrial times.
The world’s existing power plants, industrial equipment, vehicles and other CO₂-emitters are on track to pump out enough carbon dioxide to blow past that target by midcentury, researchers report July 1 in Nature.  Add in future power plants that are already planned, permitted or under construction, and we could emit enough by 2033 to raise average global atmospheric temperatures by 1.5 degrees, the researchers say. 
If we want to limit warming to 1.5 degrees, then “we cannot invest more in fossil fuel power or infrastructure,” says Thorsten Mauritsen, a physical climate scientist at Stockholm University who was not involved with the work. “Everything we do from now has to change direction and not use fossil fuels.”
In the 2015 Paris Agreement on climate change, nearly all the world’s nations agreed to try to reduce greenhouse gas emissions enough to limit warming to “well below” 2 degrees by 2100 (SN: 1/9/16, p. 6). The United States has said it would pull out of the agreement (SN Online: 6/1/17), though the exit wouldn’t be complete until 2020.
Still, calls have increased since 2015 for the more ambitious goal of keeping warming to 1.5 degrees. That would mean fewer heat waves, spells of extreme weather and species extinctions (10/27/18, p.7).

COMMITTED  Carbon dioxide emissions from the fossil fuel infrastructure that’s already built will probably push us past 1.5 degrees Celsius of global warming, according to a new study.

Europe’s latest heat wave has been linked to climate change | Science News

Global warming driven by human activity made the heat wave at least five times more likely.
Climate change made it five times more likely that Europe would experience a powerful heat wave like the one that baked the region in June, an international team of scientists reports.
The findings, released July 2 by the World Weather Attribution Network, tackle the tricky question of how the heat wave might have been linked to global warming (SN Online: 6/2/19). The extreme weather broke heat records in parts of Germany, Switzerland, Italy, Spain, the Netherlands and the Czech Republic, and set an all-time high for France of 45.9° Celsius (114.6° Fahrenheit).
Heat waves aren’t just about isolated high temperatures; the events are also defined by where, when and for how long they occur.  To identify heat wave patterns and determine if climate change played a role in the June event, the network’s scientists examined three-day averages of the average daily temperatures for France during the heat wave, and compared those to previous temperature observations as well as to climate simulations to assess the role of climate change.

Current climate conditions make the June heat wave in France up to 100 times more likely to occur than it would have been in 1901, the team found. It’s unclear exactly how much climate change contributed to that increased risk, due to several factors including that temperature observations began only in 1947. But the researchers say they are “very confident” that climate change increased the probability by at least a factor of five. The findings have yet to be peer reviewed.

June Was So Hot, Mussels Cooked to Death in Their Shells

Last month was the hottest month ever recorded on Earth, affecting vulnerable people worldwide.

The European Satellite Agency recently announced that June was the hottest month ever recorded on Earth — in fact, in California, it was so hot that mussels on rocks fried to death inside their shells.

Temperatures in Bodega Bay in northern California soared up to 75 degrees Fahrenheit and 97 degrees in San Francisco last month. And the mussels, which attach themselves to coastal rocks, were exposed to the scorching heat following many consecutive days of mid-day low tides in the area.

The animals can normally cool off and survive higher temperatures by venting the heat, but need sea breeze to carry it away. Unfortunately, the Californian shorelines witnessed no such breezes during the recent extreme heat waves, causing the mussels to die off in alarming numbers.

Jane Goodall Talks Green New Deal, Tarzan, and Avoiding the Impossible Burger

Fifty-nine years ago, Jane Goodall, an animal lover with no formal academic training, traveled to Gombe, Tanzania, to observe chimpanzees for famed anthropologist Louis Leakey. Within months, the 26-year-old witnessed a chimp extracting termites from a mound using long blades of grass, upending mankind’s very understanding of itself: Humans were no longer the only species to make tools, no longer unequivocally superior. She went on to discover that chimps,like humans, have complex social and familial hierarchies, sharp intelligence, and deep-seated wells of emotion. Goodall has spent the rest of her life devoted to conserving the world they live in, one that’s disappearing due to climate change and the interests of big business. “What we’re doing to the planet is shocking and irresponsible, and it’s all done for making money,” she says. “We’ve got to understand we need money to live, but it goes wrong when we live for money.” At 85, the founder of the Jane Goodall Institute and UN Messenger of Peace travels over 300 days a year, spreading the gospel of conservation. She spoke to ELLE from the institute’s U.S. headquarters in Washington, DC.

The kind of slow and steady observation you did for years contrasts so much with the fast-paced, technologically driven world we live in. Growing up today, would your story have been the same?
I think my story would have been very different. Screens, in a way, are killing us. I’d hesitate to say whether they totally stifle imagination, but they certainly would have stifled
mine. I read Tarzan when I was 10 and fell in love with him, and that’s what triggered my dream of going to Africa and living with wild animals. My mother saved up to take me to an early Johnny Weissmuller film, and after about 10 minutes, I burst into tears. I told her, “But that wasn’t Tarzan!” My imagination had created my own picture of Tarzan, and that’s something that the modern world certainly prevents children from doing.

If Climate Change Doesn't Kill Me, My Anxiety About It Will

How the earth's devastation is burrowing into our psyches.
Ever since I could read, my time-honored method of dealing with any kind of uncertainty has been to flood the zone with data. Terrifying-seeming symptom? Hit the CDC website to convince myself it’s probably not an aneurysm in progress. Unfamiliar destination? Learn so much about the terrain that I could double as a local travel guide. But one patch of my anxiety quilt has gone unassuaged by this information-seeking compulsion, and that’s climate change. I’ve probably read more about the topic than anyone who doesn’t need to for her job. And with every article I read, book I devour, or haunting image of an emaciated polar bear or trash-gorged whale I see, I sink deeper into the quicksand of hopelessness.

Then there’s the never-ending soundtrack that is my inner monologue: Am I abetting the decline of my own civilization? Sure, I recycle, I don’t buy throwaway fashion, I call my representatives, but I’m a part of an industry (fashion) known for stoking a demand for more, more, more, even as my own habits tend toward self-abnegation. I’m incalculably lucky that my day-to-day life hasn’t been affected by climate change in the way that so many others have. But the fact that the threat is more abstract only makes the black hole seem more menacing. When will it swallow me, my hypothetical kids, and my even-more-hypothetical grandkids?
