Carbon lurking in deep ocean threw ancient climate switch, say researchers: Slowdown of Atlantic circulation sent planet into deep freeze

A new study of sediments from the Atlantic bottom directly links this slowdown with a massive buildup of carbon dragged from the air into the abyss.

Laying the ground for robotic strategies in environmental protection

With this motivation, a team of roboticists at Harvard's Wyss Institute for Biologically Inspired Engineering has developed a robot that can autonomously drive interlocking steel sheet piles into soil. The structures that it builds could function as retaining walls or check dams for erosion control. The study will be presented

Cross-boundary solutions for wicked weeds

The issue is weeds aren't just a problem for the landowner where they grow, Bagavathiannan said..

Rainfall changes for key crops predicted even with reduced greenhouse gas emissions

The study uses four emissions scenarios from low to high to predict time of emergence (TOE) of permanent precipitation changes, meaning the year by which precipitation changes remain permanently outside their historical variation in a specific location. The research shows that quick action on emissions -- in line with 2015's

Five new frog species from Madagascar

Madagascar, an island a little larger than mainland France, has more than 350 frog species.This number of recognized species is constantly rising, and many of the newly named species are very small.

Wide variations in how well or poorly people age: United States ranks 54th between Iran (53rd) and Antigua and Barbuda (55th)

A 30-year gap separates countries with the highest and lowest ages at which people experience the health problems of a 65-year-old, according to a new scientific study.

Otherworldly mirror pools and mesmerizing landscapes discovered on ocean floor

"We discovered remarkable towers where every surface was occupied by some type of life..

Researchers tap rare pristine air to reveal pollution's impact

An international team of scientists led by Manish Shrivastava of the U.S.

Rainforest conservation in Peru must become more effective: How the effectiveness of the National Forest Conservation Program could be increased

In their publication the scientists analyze the "National Forest Conservation Program" (NFCP).It was launched by the Peruvian government in 2010 to curb the deforestation of the rainforest..

Global warming disrupts recovery of coral reefs

"Dead corals don't make babies," said lead author Professor Terry Hughes, Director of the ARC Centre of Excellence for Coral Reef Studies at James Cook University (JCU).

Researchers uncover additional evidence for massive solar storms

For the past 70 years, researchers have studied these solar storms by direct instrumental observations, which has led to an understanding of how they can pose a risk to the electrical grid, various communication systems, satellites and air traffic. Two examples of severe solar storms in modern times that caused

Few pathways to an acceptable climate future without immediate action

By adapting a popular computational climate change assessment model to better account for uncertainties in human activity and the atmosphere's sensitivity to carbon dioxide levels, the researchers created a novel method for exploring the consequences of different climate change futures to better inform policy decisions. The work is detailed in

Humans already destroyed 83% of Wildlife

According to a new scientific study, the approximate 7.6 billion human beings that populate our planet represent only 0.01% of all living beings on Earth.

Research Reveals Plants Can Think, Choose & Remember

A provocative research from 2010 published in Plant Signaling Behavior proposes that since they cannot escape environmental stresses in the manner of animals, they have developed a “sophisticated, highly responsive and dynamic physiology"

University Professor Condemns The United States Military For Geo-Engineering & Owning The Weather

Michel Chossudovsky, who is the University of Ottawa’s Emeritus Professor of Economics and has worked directly with governments on various geopolitical issues has spoken out against weather modification and the long history of its use.
