Global Action Is ‘Very Far’ From What’s Needed to Avert Climate Chaos
The global scientific consensus is clear: Emissions of planet-warming gases must be cut by nearly half by 2030 if the world is to have a good shot at averting the worst climate catastrophes. The global political response has been underwhelming so far. New climate targets submitted by countries to the United Nations would reduce emissions […]
Efficient autoxidation chain reactions demonstrated for the substance group of saturated hydrocarbons — ScienceDaily
Alkanes, an important component of fuels for combustion engines and an important class of urban trace gases, react via another reaction pathways than previously thought. These hydrocarbons, formerly called paraffins, thus produce large amounts of highly oxygenated compounds that can contribute to organic aerosol and thus to air pollution in cities. An international research team […]
Climate Threats Could Mean Big Jumps in Insurance Costs This Year
Previous efforts to increase flood insurance rates have been delayed or rolled back in the face of public pressure. In 2012, Congress passed a law that would have brought rates in line with the full risk people faced; two years later, lawmakers backed down, replacing those changes with more modest increases. FEMA’s new flood insurance […]
New sensor paves way to low-cost sensitive methane measurements — ScienceDaily
Researchers have developed a new sensor that could allow practical and low-cost detection of low concentrations of methane gas. Measuring methane emissions and leaks is important to a variety of industries because the gas contributes to global warming and air pollution. “Agricultural and waste industries emit significant amounts of methane,” said Mark Zondlo, leader of […]
Bone cancer survivor to join first private SpaceX flight

What’s Really Behind Corporate Promises on Climate Change?
There has been some progress by companies that have rigorous targets. In a report last month, Science Based Targets, which was started by the environmental groups and hundreds of businesses brought together by the United Nations, said the 338 large companies around the world for which it had sufficient emissions data collectively reduced their emissions […]
Shale gas development in PA increases exposure of some to air pollutants
Air pollution levels may have exceeded air quality standards during the development of some Marcellus Shale natural gas wells in Pennsylvania, potentially impacting more than 36,000 people in one year alone during the drilling boom, according to scientists. Source link قالب وردپرس
Texas Crisis Exposes a Nation’s Vulnerability to Climate Change
“We have to get better at understanding these compound impacts,” said Michael Craig, an expert in energy systems at the University of Michigan who recently led a study looking at how rising summer temperatures in Texas could strain the grid in unexpected ways. “It’s an incredibly complex problem to plan for.” Some utilities are taking […]
Human impact on solar radiation levels for decades — ScienceDaily
In the late 1980s and 1990s, researchers at ETH Zurich discovered the first indications that the amount of sunlight reaching the Earth’s surface had been steadily declining since the 1950s. The phenomenon was known as “global dimming.” However, a reversal in this trend became discernible in the late 1980s. The atmosphere brightened again at many […]
