Tropical forest carbon stocks vs biodiversity

As the world seeks to curb human-induced climate change, will protecting the carbon of tropical forests also ensure the survival of their species? A study published today in the leading journal Nature Climate Change suggests the answer to this question is far from straightforward. Forests with the greatest carbon content do not necessarily house the…

Climate change melting Colombia’s glaciers

The surface area of its six glaciers has shrunk from 45 square kilometers in 2010 to 37 square kilometers in 2017, for a decline of 18 percent, the Institute of Hydrology, Meteorology and Environmental Studies said. It blamed the glacier loss on “extreme events associated with natural phenomena and climate change.” If things go on…

Graphene a key for controlling water evaporation?

Graphene coatings may offer the ability to control the water evaporation process from various surfaces, according to new research. The study looked at the interactions of water molecules with various graphene-covered surfaces. The study, carried out by a team from the Chinese Academy of Sciences and the Collaborative Innovation Center of Quantum Matter (Beijing), looked…

Can This Tiny Fern Fight Climate Change and Cut Fertilizer Use?

Today, the Azolla filiculoides fern— with leaves the size of gnats — is found scattered throughout the world’s warm temperate and tropical regions. Some 50 million years ago, however, the planet was a much hotter place and Azolla grew as far north as the Arctic Ocean. Fossil records show that, fueled by abundant nitrogen and…

California exceeds 2020 greenhouse gas goals

The California Air Resources board announced Wednesday, July 11, 2018, that the state has reduced greenhouse gas emissions to 1990 levels, beating the Legislature’s target by four years. The California Air Resources Board announced Wednesday that total statewide carbon emissions fell to 429 million metric tons in 2016, a drop of 12 million tons from…

Game changing and the tragedy of the commons

Using stochastic games to analyze evolution of cooperation, leads to a surprising discovery. The tragedy of the commons is resolved if the environment deteriorates in response to defection. The new approach offers invaluable insight into how cooperation plays a role in social issues ranging from sustainability to curbing climate change. It can also help policy…

US withdrawal a set back to climate change finance

With the United States pulling out of the Paris Agreement in 2017, Former United Nations Secretary-General Ban Ki-Moon warned that there may be difficulty in mobilizing the funds necessary to effect climate change issues. Speaking to CNBC at the Singapore International Water Week on Tuesday, he said: “Now with the United States pulling from this…

300 residence seastead funded through cryptocurrency

Seasteads are mobile floating homes, businesses, and community spaces that can be moved and reconfigured in relation to other seasteads, allowing for the formation, reformation, and dissolution of networks, neighborhoods, cities, and eventually nation-states in international waters. Seasteads will offer residents and businesses liberties and regulatory frameworks that allow for rapid innovation in societal and…

Climate models fail to capture true warming under business-as-usual scenarios

Future global warming may eventually be twice as warm as projected by climate models under business-as-usual scenarios and even if the world meets the 2°C target sea levels may rise six metres or more, according to an international team of researchers from 17 countries. The findings published last week in Nature Geoscience are based on…

Climate change and land restoration

But increasingly, scientists who study ecosystems, as well as land managers who do restoration work, are questioning that model of ecological restoration, which relies on the idea of a stable “climax community,” even though many ecosystems are always changing. The West’s forests, for one, are much more dynamic than many people realize. Notwithstanding individual tree…
