Why Green Pledges Will Not Create the Natural Forests We Need…

Nations around the globe have pledged to increase their forest cover by planting millions of trees. But new research shows much of this growth would be in monoculture plantations that would be quickly cut down and do little to tackle climate change or preserve biodiversity… Read this article at Yale Environment 360: https://e360.yale.edu/features/why-green-pledges-will-not-create-the-natural-forests-we-need   Advertisements

As sea level rises, wetlands crank up their carbon storage…

Summary: Some wetlands perform better under pressure. A new study revealed that when faced with sea-level rise, coastal wetlands respond by burying even more carbon in their soils… Visit science daily for this article: https://www.sciencedaily.com/releases/2019/03/190306131401.htm

Faster CO2 Rise Expected in 2019…

During 2019 Met Office climate scientists expect to see one of the largest rises in atmospheric carbon-dioxide concentration in 62 years of measurements. The Met Office CO2 forecast is based on a combination of factors including rising anthropogenic emissions and a relative reduction in the uptake of carbon-dioxide by ecosystems due to tropical climate variability… […]

Is Warming Bringing a Wave of New Diseases to Arctic Wildlife?…

Intro: Rapid warming and vanishing sea ice in the Arctic has enabled new species, from humpback whales to white-tailed deer, to spread northward. Scientists are increasingly concerned that some of these new arrivals may be bringing dangerous pathogens that could disrupt the region’s fragile ecosystems… Read the full article here at Yale Environment 360: https://e360.yale.edu/features/is-warming-bringing-a-wave-of-new-diseases-to-arctic-wildlife

Rising temperatures and human activity are increasing storm runoff and flash floods…

Summary:  Researchers have demonstrated for the first time that runoff extremes have been dramatically increasing in response to climate and human-induced changes. Their findings show a large increase in both precipitation and runoff extremes driven by both human activity and climate change. They also found that storm runoff has a stronger response than precipitation to […]

As Greenland Warms, Nature’s Seasonal Clock Is Thrown Off-Kilter…

For millennia, ecosystems in Greenland and throughout the Arctic have been regulated by seasonal changes that govern the greening of vegetation and the migration and reproduction of animals. But a rapidly warming climate and disappearing sea ice are upending that finely tuned balance… This full article is at Yale Environment 360, read it here: https://e360.yale.edu/features/as-greenland-warms-natures-seasonal-clock-is-thrown-off-kilter

Halting biodiversity loss: Political actions are required, not additional scientific knowledge…

Summary:  Over 15 years, almost 13,000 scientific papers have been published in the leading conservation science journals. Yet biodiversity remains threatened at a global scale. Researchers have now focused on this worrisome paradox by taking a deeper look at this large volume of literature. One of the major problems is that decisions are usually more […]

Species-rich forests better compensate environmental impacts…

Summary:  To offset CO2 emissions, China is reforesting. If a mixture of tree species instead of monocultures were planted, much more carbon could be stored. An international team has shown that species-rich forest ecosystems take up more CO2 from the atmosphere and store more carbon in biomass and soil, making them more effective against climate […]
