The results of a new analysis by the International Council on Clean Transportation (ICCT) show that, when combined with a trend toward higher methane leakage and combustion slip, there is no climate benefit from using liquefied natural gas (LNG) as a marine fuel—regardless of the engine technology. First, it contains very little sulfur.
The study will appear next month in the peer-reviewed journal Climatic Change Letters. Relying more on natural gas would reduce emissions of carbon dioxide, but it would do little to help solve the climate problem. The study underscores the complex and sometimes conflicting ways in which fossil fuel burning affects Earth’s climate.
A study published in Nature Climate Change suggests that thermoelectric power plants (i.e., nuclear and fossil-fueled generating units) in Europe and the United States are vulnerable to climate change due to the combined impacts of lower summer river flows and higher river water temperatures.

Among the many climate-related vulnerabilities that can impact its mission, the US Environmental Protection Agency (EPA) cites a likely increase in tropospheric ozone pollution as potentially making it more difficult to attain National Ambient Air Quality Standards ( NAAQS ) in many areas with existing ozone problems.
Researchers at Wuhan University in China have developed a new electrochemical cell, PANI/Li x Mn 2 O 4 , for selective recovery of Li + ions from brine water with high impurity cations (K + , Na + , Mg 2+ , etc).

The climate change benefit is estimated for 2050 and human health and crop benefits are for 2030 and beyond. Black carbon and tropospheric ozone are harmful air pollutants that also contribute to climate change. What are the multiple climate, health and crop-yield benefits (by region) of implementing the measures?
The shift to electric mobility is in line with ongoing efforts to reduce the world’s dependence on fossil fuels, and reduce harmful greenhouse gas emissions responsible for climate change. It has also contributed to environment degradation, landscape damage and soil contamination, groundwater depletion and pollution.

New research shows that air pollution in eastern China has reduced the amount of light rainfall over the past 50 years and decreased by 23% the number of days of light rain in the eastern half of the country. While the light rains have diminished, pollution has increased dramatically in China in the last half of the 20 th century.
In California, reductions in emissions of black carbon since the late 1980s—mostly from diesel engines as a result of air quality programs—have resulted in a measurable reduction of concentrations of global warming pollutants in the atmosphere, according to a study examining the impact of black carbon on California’s climate.
This article shows that including offsets in climate change legislation would likely make an emissions program more cost-effective by: (a) providing an incentive for non-regulated sources to generate emission reductions; and (b) expanding emission compliance opportunities for regulated entities. Assuming the offset is legitimate—i.e.,
Europe must dramatically cut its water consumption and use water more efficiently if it is to avoid the worst impacts of water shortage, the European Environment Agency ( EEA ) warns in a new report, “Water resources across Europe—confronting water scarcity and drought”. “
When concentrations of acidic sulfate from fossil fuel emissions decrease while the concentration of more basic ammonium molecules in the atmosphere stay constant, liquid water droplets in clouds become less acidic. This makes conversion of sulfur dioxide to sulfate more efficient.
