China will be 25% forest if green goals reached: report

Almost one quarter of China will be covered with forest by 2020 if the country succeeds in its mission to build an "eco-civilization", according to a report by the United Nations Environment Programme. The report Green is Gold, released on Thursday at UNEP's headquarters in Nairobi, Kenya, looks at the …

NGOs slam Japan for investing abroad in carbon-polluting coal

Days before Japan will host a G7 summit, NGOs slammed the Asian nation for financing coal-powered energy in developing countries, even as other countries and investors shun the climate-damaging fossil fuel. Within the G7 bloc, Japan stands out for funnelling more than USD 22 billion (20 billion euros) into overseas …

Ancient Mars hosted habitable environments: study

Scientists have found evidence for widespread buried deposits of iron- and calcium-rich carbonates on Mars, which suggests that the red planet once hosted habitable environments with liquid water. "Identification of these ancient carbonates and clays on Mars represents a window into history when the climate on Mars was very different …

Climate Change Efforts Are Making Global Warming Worse, Cambridge Physicist Explains

Climate change is a global problem that has been plaguing us for years. And while experts around the world are persistent in finding ways to curb the effects of climate change, Cambridge engineering professor Michael Kelly says the attempts to fix it could actually be making the situation worse than …

Comparison of leading electric vehicle policy and deployment in Europe

This study investigates consumer incentives for electric vehicles (EVs), including plug-in hybrid electric vehicles (PHEVs) and battery electric vehicles (BEVs), in the five largest EV markets in Europe: Germany, the United Kingdom, France, the Netherlands, and Norway. These markets together account for more than 80% of all European EV registrations …

Raising ambition: State of the Voluntary Carbon Markets 2016

Voluntary buyers around the world paid to offset the equivalent of 84.1 million (M) tonnes of carbon dioxide in 2015, a 10% increase from 2014, led by private-sector companies taking proactive steps to reduce emissions ahead of regulation, according to a new report from Forest Trends’ Ecosystem Marketplace (EM). The …

Carbon emission helping Octopuses to thrive

NEW DELHI: Although unchecked carbon emissions into the atmosphere and other human actions have devastated many marine species, there is one group of creatures that seems to be thriving. These are octopuses, squids and cuttlefish, known as cephalopods. This is the conclusion arrived at by a group of researchers after …

Octopuses and squids are flourishing in a warming world

Although unchecked carbon emissions into the atmosphere and other human actions have devastated many marine species there is one group of creatures that seems to be thriving. These are octopuses, squids and cuttlefish, known as cephalopods. This is the conclusion arrived at by a group of researchers after they studied …

Antibiotic-fed cows, burping and farting may lead to climate change; Tetracycline releases potent greenhouse gas methane

A new study, published in Proceedings of the Royal Society B, has revealed that feeding cows with antibiotics may increase greenhouse gas emissions from cow dung, burps and farts. Cows feeding on antibiotic tetracycline produce more methane, a potent greenhouse gas, than any other animals not fed with the antibiotic. …

Large CO2 effluxes at night and during synoptic weather events significantly contribute to CO2 emissions from a reservoir

CO2 emissions from inland waters are commonly determined by indirect methods that are based on the product of a gas transfer coefficient and the concentration gradient at the air water interface (e.g., wind-based gas transfer models). The measurements of concentration gradient are typically collected during the day in fair weather …
