European climate maybe heading for a cool down
What is the climate waiting for Russia and Europe in 15-20 years? Will be there weather abnormalities in the coming decades? Will some areas experience more severe winter, while the others will have hot summer? It all depends on how much the climate will be affected by the dynamics of the possible onset of minimum…

Should we say goodbye to cacti?
It’s hard not to think of a cactus as a resilient plant. Living in hot, drought-stricken climates, if it can survive there, surely it can make it through anything. Sadly, this assumption is not reality for the cactus. As an international team of researchers discovered, nearly one-third of all cactus species face a looming threat…

Large Loss of Alaska Permafrost by 2100 predicted by USGS
Using statistically modeled maps drawn from satellite data and other sources, U.S. Geological Survey scientists have projected that the near-surface permafrost that presently underlies 38 percent of boreal and arctic Alaska would be reduced by 16 to 24 percent by the end of the 21st century under widely accepted climate scenarios. Permafrost declines are more likely…

Fixing Food Deserts
Food deserts, vast expanses of urban and rural areas that are void of fresh fruit and veggies, are a growing epidemic — affecting more than 23.5 million people nationwide. Disproportionately affecting occupants of poor, low-income neighborhoods, food deserts are the result of a lack of access to healthy food.

We need to use Nitrogen fertilizers more efficiently
The global population is expected to increase by two to three billion people by 2050, a projection raising serious concerns about sustainable development, biodiversity and food security, but new research led by Princeton University shows that more efficient use of nitrogen fertilizers may address both environmental issues and crop production.Today, more than half of the…

New battery can store 10 times the energy of the next best device
Industrial-scale batteries, known as flow batteries, could one day usher in widespread use of renewable energy—but only if the devices can store large amounts of energy cheaply and feed it to the grid when the sun isn’t shining and the winds are calm. That’s something conventional flow batteries can’t do. Now, researchers report that they’ve…

Why the Paris Climate Summit pledges are so important
More than 190 countries are meeting in Paris next week to create a durable framework for addressing climate change and to implement a process to reduce greenhouse gases over time. A key part of this agreement would be the pledges made by individual countries to reduce their emissions.A study published in Science today shows that…

Earth's first ecosystems were more complex than previously thought
Computer simulations have allowed scientists to work out how a puzzling 555-million-year-old organism with no known modern relatives fed, revealing that some of the first large, complex organisms on Earth formed ecosystems that were much more complex than previously thought.The international team of researchers from Canada, the UK and the USA, including Dr Imran Rahman from the…

Rapid plankton growth seen as indicator of carbon dioxide loading in oceans
A microscopic marine alga is thriving in the North Atlantic to an extent that defies scientific predictions, suggesting swift environmental change as a result of increased carbon dioxide in the ocean, a study led a by Johns Hopkins University scientist has found.What these findings mean remains to be seen, as does whether the rapid growth…
