Gaining clarity about the factors that contributed to a runaway greenhouse state on Venus, Earth’s closest planetary neighbor, can also help improve models of what could one day happen to Earth’s climate.
“Ultimately, my motivation in studying Venus is to better understand the Earth,” Kane said.

Trust in science is rising worldwide, according to a 3M-backed survey released Tuesday, and more people expect it to solve the world’s problems.
But the fifth annual 3M State of Science Index also showed many are worried that misinformation could lead to more public health crises, greater societal divisions and lack of action on climate change.
“It’s really good to see that trust in science is high, and that’s true in America and around the world, but misinformation threatens scientific credibility,” Jayshree Seth, 3M’s corporate scientist and chief science advocate, said in an interview. “It’s not simply a matter of communicating facts, data and evidence. We need to build that relationship with the public.”
The official start of Atlantic Hurricane Season is less than six weeks away, and forecasters will be getting an essential upgrade just in time for the season to begin.
New technology from the University of Wisconsin will help with preparation of more detailed forecasts and provide more reliable information to meteorologists and emergency planners, which should ultimately result in better, safer outcomes for public safety.
The Advanced Dvorak Technique (ADT) is a satellite-based method for determining tropical cyclone intensity. Planned upgrades include the use of full-resolution images from weather satellites, better identification of the location of each storm’s eye and the ability to better analyze hurricanes occurring outside tropical regions.
Please welcome a second posting here at 21st Century Tech Blog, from Katie Brenneman. Katie’s previous contribution looked at how individuals can practice sustainability to mitigate the threat of climate change. Her many interests include writing on lifestyle, mental health, and sustainability. You can follow her on Twitter.
In this contribution, Katie has chosen a timely topic: the increasing consumer interest in electric vehicles (EVs). The recent stratospheric rise in gasoline and diesel prices because of Russia’s invasion of Ukraine has made EVs far more attractive. That plus more announcements about new EV models, i.e., The Ford Lightning (an EV version of the F-150) may prove to be the moment when North Americans begin a rapid move away from fossil-fuel-powered vehicles?
As fuel prices continue to rise around the world, many consumers are taking another look at EVs as a potential solution for their transportation needs. This follows historical trends that show whenever there is a spike in gas and diesel costs it is accompanied by an increase in EV sales. Online searches for EVs continue to double with many in the renewable energy sector wondering if this is the watershed moment that will finally move us to take zero-emission actions seriously.
“I cannot take your philanthropy on climate change seriously when you have a massive short position against Tesla,” Musk told Gates, per the texts.
Architect Andreas Tjeldflaat from design and research studio, Framlab, has his head high up in the clouds.
His latest project, titled Oversky, was recently on display at an exhibition on architecture and climate change at Sweden’s Bildmuseet art museum.
Oversky deals with a series of semi-floating structures in the ariel space between roads and buildings. The modular structures would be based on the technology that allows zeppelins to float, known as the lighter-than-air technology, and would be interconnected and supported by various infrastructural links that connect the street, known as “the cloudscape”.
China is using loopholes in climate agreements to continue to build and operate coal-fired power plants.
China produces and consumes half the world’s coal and despite recent climate pledges, it remains deeply bound to continuing to use this energy source.
A major challenge for producers of electricity from solar panels and wind turbines is akin to capturing lightning in a bottle. Both solar and wind increasingly generate electricity amid little demand, when market prices are too low to cover costs. At noon on sunny days, for example, wholesale power prices in areas with high quantities of solar and wind occasionally fall below zero.
Some renewable energy producers store their excess electricity as green hydrogen, using the electricity to produce hydrogen from water—labeled “green” because the process emits no carbon dioxide. Used to create fuels, fertilizer, and other chemicals, the global hydrogen market is about $125 billion, and it’s growing briskly in part due to increased interest in hydrogen as a fuel for buses, trucks, and even ships. The problem is that producing hydrogen with electricity remains fairly expensive, so it’s only profitable to sell at the higher prices paid by lower-volume customers.
But now, researchers at Stanford University and at the University of Mannheim in Germany have found a possible solution: integrated reversible power-to-gas systems that can easily convert hydrogen back to electricity when power prices spike higher.
Safety avionics specialist Iris Automation has made a meteorological enhancement to its Casia G ground-based surveillance system with the integration of TruWeather Solutions sensors and services – a move aiming to add climate security to the company’s aerial detect-and-avoid protection.
Addition of a precision weather utility was a natural step in Iris Automation’s wider objective of ensuring flight safety of, and between, crewed aircraft and drones The company says local micro weather and low-altitude atmospheric conditions often differ considerably from those at higher levels. That differential creates a larger degree of weather uncertainty for aerial service providers, who weigh safety factors heavily into whether they make flights as planned or not.
