Five Things the “Nuclear Bros” Don’t Want You to Know About Small Modular Reactors

Union of Concerned Scientists

Even casual followers of energy and climate issues have probably heard about the alleged wonders of small modular nuclear reactors (SMRs). This is due in no small part to the “ nuclear bros ”: an active and seemingly tireless group of nuclear power advocates who dominate social media discussions on energy by promoting SMRs and other “advanced” nuclear technologies as the only real solution for the climate crisis.

New study suggests the Atlantic overturning circulation AMOC “is on tipping course”

Real Climate

A new paper was published in Science Advances today. Its title says what it is about: “Physics-based early warning signal shows that AMOC is on tipping course.” The study follows one by Danish colleagues which made headlines last July, likewise looking for early warning signals for approaching an AMOC tipping point (we discussed it here ), but using rather different data and methods.

Ask a Scientist: How Close Are We to a Clean Energy Transition?

Union of Concerned Scientists

After the hottest summer on record, the world continues to witness extreme weather fueled by the burning of fossil fuels. In the United States alone, we’re in the midst of a record-setting hurricane season, with back-to-back destructive hurricanes, Helene and Milton, causing immense destruction in Florida and neighboring states. Both hurricanes were exacerbated by warmer ocean surface temperatures, and are examples of “what hurricanes will look more like in the future,” according to Dr.

Hurricanes Helene and Milton Further Proof We’re Not Ready for Fossil Fuel-Caused Climate Change  

Union of Concerned Scientists

In August, the National Oceanic and Atmospheric Administration (NOAA) issued its updated forecast for the 2024 hurricane season. It was to be above normal in every regard: more named storms and stronger hurricanes than usual. One of the main reasons for this forecast? Significantly warmer than usual surface temperatures in the Atlantic Ocean, which come largely as a result of human-caused climate change.

How to Make Trees Worth More Standing Than Cut Down

Legal Planet

West of Sydney, Australia, lies the Blue Mountains, a range of plateaus and panoramic canyons forested with eucalyptus trees. Oil in the leaves produces a bluish haze, hence the name of the area. Twenty-five years ago, in 1999, a new NGO called Forest Trends brought together a small international group to the town of Katoomba to brainstorm over increasing capital flows to protect nature, how to “make trees worth more standing than cut down.

Going back a few months, I spent a bit of time pointing out the strategy and nonsense in the various Willie Soon and company’s efforts to blame current warming on solar activity. I specifically pointed out their cultish devotion to a single solar activity reconstruction (Hoyt and Schatten, 1993) (HS93); with an update from Scaffeta (2023) , and their increasingly elaborate efforts to create temperature series that correlate to it.

A recent sensible-sounding piece by Roy Spencer for the Heritage foundation is full of misrepresentations. Let’s play spot the fallacy. Comparing climate models to observations is usually a great idea, but there are some obvious pitfalls to avoid if you want to be taken seriously. The most obvious one is to neglect the impacts of internal variability – which is not synchronized across the models or with the observations.

EVs Are at a Turning Point, It May Not Be What You Think

Union of Concerned Scientists

There’s been a lot of nay-saying around EVs lately, including, amongst other things, worries that EV sales are stalling out now that all the early adopters have already made the switch and mainstream buyers aren’t ready to dive in. I wouldn’t blame you if you thought nobody was buying EVs or that sales were about to plummet. While there are some near term headwinds, I’ve never had as much confidence in the ability to zero out tailpipe emissions from our cars and trucks.

Driving on Electricity Is Now Much Cleaner than Using a Gasoline Car

Union of Concerned Scientists

Replacing gasoline with electricity greatly reduces the carbon emissions from driving. Based on where electric vehicles (EVs) have been sold, driving the average EV in the US produces global warming emissions equal to a hypothetical 94 mile per gallon gasoline car, or less than a third of the emissions of the average new gasoline car. Transportation is the largest sector for emissions , and passenger cars, trucks, and SUVs are the majority of transportation emissions, so there is no way to slow

Power plants fueled by methane gas have a serious climate problem. The fuel, commonly known as natural gas, now powers the biggest portion of US electricity generation—more than 40 percent. It has also grown to be the largest source of carbon pollution from the US power sector, even as zero-carbon renewable energy has been growing by leaps and bounds.
