It’s a contrarian idea that questions conventional thinking about international aid, it has low overhead, it’s easily scalable using mobile phones, and it’s measurable.Faye, the GiveDirectly cofounder, called the study “the first ever A/B test for USAID.” Zeitlin, the Georgetown professor and coauthor of the study, says this research aligns with Silicon Valley’s interest in disruptive ideas because it questions the effectiveness of traditional aid programs.A recent cash-transfer study showed early gains disappearing over time.
In some areas with high levels of plastic pollution, like the Mediterranean and the southern Atlantic Ocean, turtles are unable to avoid the debris, while in other areas it is less of a problem.“We know individual turtles are dying, but we don’t know yet whether enough turtles are dying to cause population decline, and that’s where we’re heading to now,” Dr. Hamann said.Jennifer Lynch, a research biologist with the National Institute of Standards and Technology in Hawaii, took issue with the way the study measured vulnerability to plastic.In her own research, she has seen animals that aren’t harmed after swallowing 300 pieces of plastic, so she doesn’t believe that 14 pieces pose such a high risk of death.
“The large amount of rain that is going to come out of a tropical storm or hurricane anyway fell in the same place over a long period of time.”To analyze the changes in translation speeds, James Kossin, a climate scientist with the National Centers for Environmental Information at the National Oceanic and Atmospheric Administration, tapped into a global data set on past tropical storms.
But this study is among the first to model how wind and solar farms would affect the Sahara, all while considering how growing green plants and trees would respond to these changes, said Li, who started the study while a postdoctoral researcher in the Department of Atmospheric and Oceanic Science at the University of Maryland.
A new study finds that warming in the Atlantic Ocean is changing rain patterns in the Amazon Previous researchers who have looked at the Amazon and its changing precipitation have found that the southern part of the rainforest has experienced a long-term increase in rainfall.
Rather, these penguins, who were mummified by the cold, dry Antarctica environment, likely died from weather on the opposite end of the spectrum: two extremely rainy and snowy events that happened over the past 1,000 years, a new study finds.
Data centers are built on land, and most of the physical elements of the internet – such as the cables that connect households to internet services and the fiber optic strands carrying data from one city to another – are buried in plastic conduit under the dirt.
GETTYA two metre jump could see a host of major cities be partially submergedCo-author John Fasullo, a climate scientist at the National Center for Atmospheric Research, said: "This study highlights the important role that can be played by satellite records in validating climate model projections.”If the calculations are correct, it would mean that sea levels could rise by almost one metre by 2100, which would be devastating for island countries around the globe.
Worldwide, insect pests consume up to 20 percent of the plants that humans grow for food, and that amount will increase as global warming makes bugs hungrier, according to a study published Thursday in the journal Science.That could encourage farmers to use more pesticides, which could cause further environmental harm, scientists said.For every degree Celsius (two degrees Fahrenheit) that temperatures rise above the global historical average, the amount of wheat, corn, and rice lost to insects will increase by 10 to 25 percent, the study says.
The Great Barrier Reef harbours extensive areas of deep coral reefs which are much more difficult to study and were previously considered a refuge from higher water temperatures near the surface.
If you included all the global emissions produced in the course of making things like the imported steel used in London’s skyscrapers and cars, then Britain’s total carbon footprint has actually increased slightly over that time.“It’s a huge problem” said Ali Hasanbeigi, a research scientist and C.E.O. of Global Efficiency Intelligence, an energy and environmental consulting firm.
Heatwave warning: Soaring temperatures to kill tens of thousands in the future HEATWAVES will kill people in their tens of thousands in the near future unless humanity can find a way to adapt to soaring global temperatures, researchers have found.
Arctic lakes could release a vast reservoir of ancient carbon buried deep under the permanently frozen ground, or permafrost, thereby accelerating climate change.
The fossil records show that the world is very sensitive to temperature changes, which suggests that if fossil fuel emissions continue unabated, accelerated warming could lead to dramatic transformations in vegetation and ecosystems around the globe, the team wrote today (Aug. 30) in the journal Science.
The megafires paper is one of two recently released studies based on data from NASA’s Arctic Boreal Vulnerability Experiment, or ABoVE, that will help scientists better understand and predict both short- and long-term changes in the ecosystems of Alaska and Northern Canada.
Although drought and overgrown forests are often blamed for major fires in the western United States, new research using unique NASA before-and-after data from a megafire site indicates that highly localized winds sometimes play a much larger role -- creating large, destructive fires even when regional winds are weak.
A new NASA-led study using data from the Arctic Boreal Vulnerability Experiment (ABoVE) shows that carbon in Alaska's North Slope tundra ecosystems spends about 13 percent less time locked in frozen soil than it did 40 years ago.
A single season of drought in the Amazon rainforest can reduce the forest's carbon dioxide absorption for years after the rains return, according to a new study published in the journal Nature.
The red points overlaid on the image designate those areas that by using thermal bands detect actively burning fires. NASA's Earth Observing System Data and Information System (EOSDIS) Worldview application provides the capability to interactively browse over 700 global, full-resolution satellite imagery layers and then download the underlying data.
The researchers also say that the deadline to stop global warming reaching 1.5C has already passed, unless we commit to radical action now. Without that action, Earth will fall past the point of no return and it will be impossible to stop global warming, they warn.
“In some temperate countries, insect pest damage to crops is projected to rise sharply as temperatures continue to climb, putting serious pressure on grain producers,” said Professor Joshua Tewksbury, co-lead author of the study and a research professor at the University of Colorado Boulder.
By 2050, an estimated 83.7 million people over the age of 65 will call the US home, nearly doubling the current population—and a paper published in April found that bad smoke days during California’s 2015 wildfire season caused spikes in emergency room visits, with the most pronounced impact on patients over 65.
And it is lowest in the morning."A temperature of 99 at six o’clock in the morning is very abnormal, whereas that same temperature at four o’clock in the afternoon can be totally normal," says Jonathan Hausmann, a rheumatologist at Boston Children’s Hospital and Beth Israel Deaconess Medical Center in Boston, who gathered 11,458 temperatures in crowdsourced research using an iPhone app called Feverprints.The study, published online this month in the Journal of General Internal Medicine, refutes the age-old benchmark of 98.6 degrees Fahrenheit.
The resulting analysis shows – for the first time – that the cost effectiveness of nature-based (green), artificial (gray) and policy solutions (like regulations) for reducing risk from storms and sea level rise can be directly compared – quantitatively – (apples to apples, so to speak) to one another across a region as large as the Gulf of Mexico.
And two of these factors — water depth and structural complexity — are easily and cheaply identifiable by somebody managing a reef. This paper gives reef managers an easily measurable tool that can be used to predict recovery and resilience.
A new study on the Australia’s Great Barrier Reef is one of the first to expose the effect that ocean acidification is already having on coral reefs. Reversal of ocean acidification enhances net coral reef calcification.
The big takeaway: The countries with the most to gain — in terms of risk reduction — from reef conservation and restoration of their coral reefs are Indonesia, the Philippines, Malaysia, Mexico, and Cuba, where annual expected flood savings exceed $400M for each nation.
