Heatwaves that occur over land are well known for having adverse impacts on human health, infrastructure and agriculture. Less attention has been paid to analogous episodes in the ocean, dubbed marine heatwaves (MHWs), but interest in these transient events is growing as their potentially dramatic ecological and economic impacts1 have become clear. This enhanced awareness of the importance of MHWs has fostered a desire to understand their causes and whether they can be predicted. Writing in Nature Communications, Holbrook et al.2 present the first comprehensive analysis of MHWs across the globe. They identify specific drivers of these events, as well as associations between MHWs and known climate
Democratic presidential hopeful Sen. Elizabeth Warren's, D-Mass., attempt to use the 50th anniversary of the moon landing to unite America on climate change won't work, according to Fox Business host Kennedy. Instead, Democrats -- and some Republicans -- seem to need Americans to be divided in order to thrive in the current political environment, Kennedy claimed on "The Five." "The difference between the Apollo program and now -- Elizabeth Warren is saying we all came together and we got guys on the moon, and it was pretty historic," she said. "But you need to bring people together in order to do that, and these people cannot exist... unless there is constant division. And that's Elizabeth Warren,
Distilling vast archives of unstructured text into the orderly tables of ngram word histograms makes it possible to explore the linguistic patterns underlying those collections. In the case of television news, translating the decade of coverage monitored by the Internet Archive's Television News Archive into a 4-billion-row ngram dataset capturing the linguistic choices of ABC, Al Jazeera, BBC News, CBS, CNN, DeutscheWelle, FOX, Fox News, NBC, PBS, Russia Today, Telemundo and Univision at 30-minute resolution over the last ten years, opens the door to myriad new linguistic analyses. The new Television News Ngrams dataset, constructed from the Internet Archive's Television News Archive, comprises more than 1.2 billion unigrams and 2.8 billion bigrams covering 13 stations representing more than 4 billion total words of closed captioning over the past decade.
If human species somehow manage to survive the apocalyptic disaster of climate change, the Paris Agreement 2015 would be remembered as a remarkable achievement in the history of civilisation. After repeated failures of several UNFCC treaties including Kyoto Protocol, the Paris Agreement emerged as the last ray of hope for humanity attracting unprecedented participation. Taking lessons from the failure of top to bottom approach of previous climate treaties, the Paris Agreement shifted towards a softer legal mechanism requiring voluntary contributions from the States. Though adopted in 2015, but sudden withdrawal of Trump Administration from the treaty along with the dwindling attitudes of few
Iceland is planning to mark the passing of Okjokull, its first glacier lost to climate change which threatens some 400 others on the subarctic island. On August 18, a plaque will be unveiled to Okjokull -- which translates to "OK glacier" -- in the west of Iceland, local researchers and their peers at Rice University in the United States, who initiated the project, said Monday. "This will be the first monument to a glacier lost to climate change anywhere in the world," Cymene Howe, Associate Professor of Anthropology at Rice University, said in a statement.
Newswise — Private, independent firms are less likely to pollute and incur EPA penalties than public and private equity-owned firms, according to new research from the University of Notre Dame. “Corporate governance and pollution externalities of public and private firms” is forthcoming in the Review of Financial Studies from Sophie Shive and Margaret Forster, finance professors in Notre Dame's Mendoza College of Business. They found that private, independent firms have lower carbon emissions from their operations, controlling for their size and output, than public and private equity-owned firms. “This is a very tough question to answer in a general sample of firms,” Shive says, “because one
Restoring peat moors degraded by farming may prove a relatively inexpensive way of tackling climate change, a report shows. Wet peat bogs store carbon that's been sucked from the air by plants, but many bogs have been drained for farming. As drained peat dries, CO2 is produced - so in that sense peat's causing a climate problem like cars, planes and factories. But statisticians say parts of the peat problem may be relatively cheap and easy to solve. They say the benefit of blocking up drainage ditches and bringing back vegetation to the moors shows benefits way higher than the cost. Who has done the numbers? The sums have been done by the Office for National Statistics (ONS), which reports to
Reducing air travel may have a positive effect on climate change but it will inevitably damage developing countries that rely on tourism for their chances of prosperity.
For ecologists who study how plants respond to climate changes in the hot deserts of North America, hoarding has its uses. In a new study out this week in Ecology, these ancient desert packrats left valuable clues—clues that helped NAU researchers to decipher what kinds of plant species are best able to move during extended periods of warming and drying. The research team, led by Bradley Butterfield from NAU's Center for Ecosystem Science and Society (Ecoss) and including Scott Anderson from the School of Earth and Sustainability, found that a plant's evolutionary build—its growth form (tree vs. shrub) and how its seeds are dispersed—are strong predictors of how quickly it can move to a more favorable climate when its current one becomes hotter or drier. The clues on which Butterfield and his collaborators from SUNY-Buffalo and the U.S. Geological Survey relied come in the form of ancient middens—the nests that packrats make with nearby plant material and inadvertently fossilize with their urine, called amberat.
Lately, climate change has imposed itself on the public sphere. Through extreme events linked to changes in the climate, new scientific reports and studies, and rejuvenated youth movements (along with many other political, economic, scientific, ecological, meteorological and cultural events and issues) climate change has been increasingly difficult to ignore. But you wouldn't really have picked up on that in the first round of the U.S. Democratic party primary debates that took place in Miami, Florida. As 20 candidates made their case to the American people, it was striking how minimally and shallowly they discussed climate change. Sadly, this illustrates a contradiction we have been living with
University of Exeter A decade without any global warming is more likely to happen if the climate is more sensitive to carbon dioxide emissions, new research has revealed. A team of scientists from the University of Exeter and the Centre of Ecology and Hydrology in the UK has conducted pioneering new research into why both surges and slowdowns of warming take place. Using sophisticated climate models the team, led by PhD student Femke Nijsse, discovered if the climate was more sensitive to CO2 concentration also displayed larger variations of warming over a decade. When combined with information from simulations without any carbon dioxide increases, the authors were able to assess the natural
“Fredrik Andersson's family has run a farm in Arboga, Sweden, for three generations. It's only in recent years that the seven-decade-old farm, now 450 hectares, has had to face up to climate change–induced extreme weather, he says. But for the farm — about 100 miles west of Stockholm — that produces wheat, rapeseed, oats and malt barley, in addition to perennial grasses such as timothy, the change isn't all bad. Now, says Andersson, both dry and wet seasons last longer than they did a couple of years ago. Crucially, he says, “we have a longer growing season,” which has produced increasing yields of winter wheat. Globally, climate change is predicted to lead to vanishing glaciers, swelling seas,

Due to climate change, ancient murals in Val Verde County, Texas are at risk of being washed away. These archaeologists are preserving their historical record. In Texas' Lower Pecos Canyonlands, Shumla Archaeological Research & Education Center has been documenting some of the oldest narrative mural paintings in North America. Shumla is racing against time to document these murals, as local rivers that surround them are rising at an alarming rate, due to the changing climate, and are slowly degrading the original artwork. Because of their location and condition, Shumla hopes that these murals, some of them 4,000 years old, might one day be displayed as 3D models or with the help of VR, in museums
