Published North Atlantic Oscillation contributes to 'cold blob' in Atlantic Ocean
(via sciencedaily.com) Original source A patch of ocean in the North Atlantic is stubbornly cooling while much of the planet warms. This anomaly -- dubbed the 'cold blob' -- has been linked to changes in ocean circulation, but a new study found changes in large-scale atmospheric patterns may play an equally important role, according to an international research team.
Published California's winter waves may be increasing under climate change
(via sciencedaily.com) Original source A new study uses nearly a century of data to show that the average heights of winter waves along the California coast have increased as climate change has heated up the planet.
Published Secondary forests more sensitive to drought than primary forests
(via sciencedaily.com) Original source The dry summer of 2018 hit Swedish forests hard -- and hardest affected were the managed secondary forests.
Published Scientists caught Hofstadter's butterfly in one of the most ancient materials on Earth
(via sciencedaily.com) Researchers have revisited one of the most ancient materials on Earth -- graphite, and discovered new physics that has eluded the field for decades.
Published New research method determines health impacts of heat and air quality
(via sciencedaily.com) Original source The planet experienced the hottest day on record earlier this month and climate projections estimate the intensity of heat waves and poor air quality will increase and continue to cause severe impacts. Researchers have refined and expanded a method of data collection to assess their health impacts.
Published Washable, transparent, and flexible OLED with MXene nanotechnology?
(via sciencedaily.com) Transparent and flexible displays, which have received a lot of attention in various fields including automobile displays, bio-healthcare, military, and fashion, are in fact known to break easily when experiencing small deformations. To solve this problem, active research is being conducted on many transparent and flexible conductive materials such as carbon nanotubes, graphene, silver nanowires, and conductive polymers.
Published Risk of fatal heart attack may double in heat wave and high fine particulate pollution days
(via sciencedaily.com) Original source An analysis of more than 202,000 heart attack deaths between 2015-2020 in a single Chinese province found that days that had extreme heat, extreme cold or high levels of fine particulate matter (PM2.5) air pollution were significantly associated with the risk of death from a heart attack, especially in women and older adults.
Published Long-term changes in waves and storm surges have not impacted global coastlines
(via sciencedaily.com) Original source Changes in ocean wave and storm conditions have not caused long-term impacts on sandy coastlines in the past 30 years, a new study has found.
Published Climate science is catching up to climate change with predictions that could improve proactive response
(via sciencedaily.com) Original source In Africa, climate change impacts are experienced as extreme events like drought and floods. It has now been possible to predict and monitor these climatic events, providing early warning of their impacts on agriculture to support humanitarian and resilience programming in the most food insecure countries of the world.
Published Researchers put a new twist on graphite
(via sciencedaily.com) Original source Researchers report that it is possible to imbue graphite -- the bulk, 3D material found in No. 2 pencils -- with physical properties similar to graphite's 2D counterpart, graphene. Not only was this breakthrough unexpected, the team also believes its approach could be used to test whether similar types of bulk materials can also take on 2D-like properties. If so, 2D sheets won't be the only source for scientists to fuel technological revolutions. Bulk, 3D materials could be just as useful.
Published Our favorite vintages and their precarious mountainside homes are at risk due to climate change, environmental scientists warn
(via sciencedaily.com) Original source Tucked into the hillsides of Italy, Portugal, and Spain, some of the world's most famous -- and most difficult to maintain -- vineyards are heralded for their unique flavor profiles and centuries of tradition. But as extreme weather and changing socioeconomic conditions make this so-called 'heroic viticulture' even more challenging, scientists worry these grapes and their cultural histories are at risk. Researchers argue that farmers and scientists must work together to protect some of the world's most celebrated wines.
Published Supercomputer used to simulate winds that cause clear air turbulence
(via sciencedaily.com) Using Japan's most powerful supercomputer, researchers reproduced cases of clear air turbulence around Tokyo. They simulated the fine vortices responsible for this dangerous phenomenon. The usefulness of the simulation in predicting turbulence was confirmed by comparing simulation data with data from aircraft recordings. This research should improve the forecasting of turbulence.
Published A bright future in eco-friendly light devices, just add dendrimers, cellulose, and graphene
(via sciencedaily.com) Original source Researchers have developed a light-emitting electrochemical cell using dendrimers, a material gaining popularity in the industry. Moreover, the team found that using biomass derived cellulose acetate as the electrolyte retains the cell's long-life span. Combined with a graphene electrode, the cell has the potential to light the way for a future of eco-friendly and flexible light-emitting devices.
Published Marine heat waves caused mass seabird die-offs, beach surveys show
(via sciencedaily.com) Original source New research uses data collected by coastal residents along beaches from central California to Alaska to understand how seabirds have fared in recent decades. The paper shows that persistent marine heat waves lead to massive seabird die-offs months later.
Published Three things to know: Climate change's impact on extreme-weather events
(via sciencedaily.com) Original source Researchers found that the effects of climate change on the intensity, frequency, and duration of extreme weather events, like wildfires, could lead to massive increases in all three.
Published Birds raise fewer young when spring arrives earlier in a warming world
(via sciencedaily.com) Original source A new study of North American songbirds finds that birds can't keep up with the earlier arrival of spring caused by climate change. As a result, they're raising fewer young. By the end of the 21st century, climate change will cause springlike weather to begin 25 days earlier, but birds will only breed about seven days earlier. That change could lead to an average reduction of 12% in breeding productivity for songbird species.
Published New study reveals abrupt shift in tropical Pacific climate during Little Ice Age
(via sciencedaily.com) Original source An El Niño event has officially begun. The climate phenomenon, which originates in the tropical Pacific and occurs in intervals of a few years will shape weather across the planet for the next year or more and give rise to various climatic extremes. El Niño-like conditions can also occur on longer time scales of decades or centuries. This has been shown to have occurred in the recent past.
Published Scientists propose new strategy for modern sails to help shipping sector meet its carbon reduction goals
(via sciencedaily.com) Original source Researchers have identified a strategy that can offset the random and unpredictable nature of weather conditions that threaten carbon emission reduction efforts in the shipping sector.
Published 'Electronic skin' from bio-friendly materials can track human vital signs with ultrahigh precision
(via sciencedaily.com) Original source Researchers have used materials inspired by molecular gastronomy to create smart wearables that surpassed similar devices in terms of strain sensitivity. They integrated graphene into seaweed to create nanocomposite microcapsules for highly tunable and sustainable epidermal electronics. When assembled into networks, the tiny capsules can record muscular, breathing, pulse, and blood pressure measurements in real-time with ultrahigh precision.
Published Freely available risk model for hurricanes, tropical cyclones
(via sciencedaily.com) Original source As human-driven climate change amplifies natural disasters, hurricanes and typhoons stand to increase in intensity. Until now, there existed very few freely available computer models designed to estimate the economic costs of such events, but a team of researchers has recently announced the completion of an open-source model that stands to help countries with high tropical cyclone risks better calculate just how much those storms will impact their people and their economies.
