A New Tandem Catalyst Converts Carbon Dioxide into Valuable Multicarbon Products More Selectively
Electrochemical reduction can convert carbon dioxide into multicarbon products for use as a raw material in chemicals and fuels. In this research, scientists improved this conversion process by using a tandem catalyst electrode. The electrode includes a silver or iron-nitrogen-carbon-based catalyst to convert carbon dioxide into carbon monoxide and incorporates a second segment that contains a copper catalyst to convert carbon monoxide into multicarbon products. Relative to prior methods, the developed approach more selectively converts carbon dioxide into desired compounds.

Albany, N.Y. (July 1, 2022) – The U.S. Supreme Court on Thursday limited the Environmental Protection Agency (EPA)’s authority to set climate standards for power plants. The court’s 6-3 ruling – which addressed an Obama-era regulation aimed at coal-fired power…
Including all types of emissions shortens timeline to reach Paris Agreement temperature targets
Instead of focusing on carbon dioxide’s effect on future temperature, new research includes the related human-generated emissions of methane, nitrogen oxide and particle pollution. Expanding the scope increases the amount of future warming that is already guaranteed by past emissions, and shortens the timeline to reach the Paris Agreement temperature targets.

Catastrophic Sea-Level Rise from Antarctic Melting is Possible with Severe Global Warming
The Antarctic ice sheet is much less likely to become unstable and cause dramatic sea-level rise in upcoming centuries if the world follows policies that keep global warming below a key 2015 Paris climate agreement target, according to a Rutgers coauthored study. But if global warming exceeds the target – 2 degrees Celsius (3.6 degrees Fahrenheit) – the risk of ice shelves around the ice sheet’s perimeter melting would increase significantly, and their collapse would trigger rapid Antarctic melting. That would result in at least 0.07 inches of global average sea-level rise a year in 2060 and beyond, according to the study in the journal Nature.

What Happens in Vegas, May Come From the Arctic?
Climate records from a cave in the southern Great Basin show that Nevada was even hotter and drier in the past than it is today, and that one 4,000-year period in particular may represent a true, “worst-case” scenario for the Southwest and the Colorado River Basin — and the millions of people who rely on its water supply.
New international analysis narrows the range in sensitivity of climate to CO2
The most advanced and comprehensive analysis of climate sensitivity undertaken has revealed with more confidence than ever how sensitive the Earth’s climate is to carbon dioxide.
This new research finds that the true climate sensitivity is unlikely to be in the lowest part of the 2.7-8.1˚F range. The analysis indicates that if atmospheric carbon dioxide levels double from their pre-industrial levels and are maintained, the world would be likely to experience eventual warming from 4.1-8.1˚F. There would be less than 5 percent chance of staying below 3.6˚F and a 6-18 percent chance of exceeding 8.1˚F.
Geoengineering is Just a Partial Solution to Fight Climate Change
Could we create massive sulfuric acid clouds that limit global warming and help meet the 2015 Paris international climate goals, while reducing unintended impacts? Yes, in theory, according to a Rutgers co-authored study in the journal Earth System Dynamics. Spraying sulfur dioxide into the upper atmosphere at different locations, to form sulfuric acid clouds that block some solar radiation, could be adjusted every year to keep global warming at levels set in the Paris goals. Such technology is known as geoengineering or climate intervention.

California can become carbon neutral by 2045
Lawrence Livermore National Laboratory (LLNL) scientists have identified a robust suite of technologies to help California clear the last hurdle and become carbon neutral – and ultimately carbon negative – by 2045. This groundbreaking study, “Getting to Neutral: Options for Negative Carbon Emissions in California,” was conducted as part of LLNL’s expansive energy programs work and the Laboratory’s Carbon Initiative. The goal of the initiative is to identify solutions to enable global-scale CO2 removal from the atmosphere and hit global temperature targets.
