EU-komissio esittää kevennyksiä päästökauppaan ja aikoo hidastaa päästövähennystavoitetta.
Greenpeacen Juha Aromaa vastustaa, koska ilmastokriisi on pidemmällä kuin kuviteltiin.
EK:n Kati Ruohomäki pitää esitystä hyvänä ja tasapainoisena.
Päästökaupan oli määrä loppua 2039, nyt se jatkuu. Suomi vastustaa, koska on jo siirtynyt vähäpäästöiseen teknologiaan.

“Planted forests can be a powerful short-term tool for carbon uptake, but this advantage is temporary,” Luo told Live Science. “For long-term carbon storage and resilience, natural forests remain irreplaceable.”

After being laid off by the Trump administration as part of DOGE-era job cuts, a group of scientists previously part of the National Oceanic and Atmospheric Administration (NOAA) have set up their own independent website to preserve more than 15-years worth of vital climate data.

The site itself, named Climate.us, doesn’t just provide data – although there’s plenty of that to go around – as it has already released potentially vital news and features, alongside various teaching resources to help people better understand the climate.

Scientists Propose Dimming Sun to Combat El Niño
It’s a controversial proposal.

Last month, the United Nations warned that this year’s El Niño, a naturally occurring climate pattern characterized by unusually warm ocean surface temperatures throughout the Pacific, would be particularly extreme.

“The world must treat it as the urgent climate warning it is,” the World Metereological Organization cautioned at the time. “El Niño conditions will pour fuel on the fire of a warming world.”

Indeed, the National Oceanic and Atmospheric Administration (NOAA) confirmed that there was a rising chance of a “very strong” El Niño, triggering drastic temperature swings and more frequent extreme weather events, from severe storms to major flooding. Meanwhile, human-driven climate change will only amplify these effects, making this summer particularly precarious.

Air conditioning is essential for protecting people during dangerous heat waves, but it also has a significant environmental impact. Cooling buildings uses about 7% of the world’s electricity and produces roughly 3.2% of global greenhouse gas emissions.

In the United States, air conditioners emit an estimated 150 million metric tons of CO₂ each month during summer, an amount comparable to the Netherlands’ total annual carbon emissions. This highlights the large energy demand associated with cooling.

As global temperatures rise, more people rely on air conditioning to stay safe. However, if that electricity comes from fossil fuels, it increases greenhouse gas emissions, creating a cycle where hotter weather leads to greater cooling demand and even more warming.

Millions of people in developing countries still lack access to reliable cooling despite facing extreme heat. Expanding access to air conditioning is vital for saving lives, but it must be done in a way that minimizes environmental impact.

Experts say the solution is not to stop using air conditioning, but to make it cleaner and more efficient through renewable energy, energy-efficient cooling systems, better building insulation, passive cooling designs, reflective roofs, and greener cities with more trees and shade.

Remember How Sucking Carbon Out of the Air Was Going to Save the Planet? We Have Terrible News
To say we’re way behind schedule is an understatement.

The idea of sucking CO2 out of the atmosphere to combat climate change might be a necessary intervention, but it always sounded like a longshot.

Unfortunately, it seems like the strategy is already hitting a wall. A new report published this week found that ongoing carbon dioxide removal (CDR) efforts are barely putting a dent in the fight against global warming — and that for them to start making an impact, they would need to be scaled up at a rate that rivals the adoption of solar panels.

In other words, we’re not doing it big enough, and we’re not doing it fast enough. And the longer we wait to get the ball rolling, the more carbon removal we’ll need to do to mitigate climate impacts.

“Countries have pledged around 2.7 billion [metric tons] of carbon removal by 2035 and about 3.6 billion by 2050, but climate pathways require much more, especially in the long term,” report coauthor William Lamb, a scientist at the Potsdam Institute for Climate Impact Research, told The Guardian. “This leaves a gap that grows significantly over time.”

Scientists generally agree that CDR efforts will play a small but necessary role in limiting global warming to within 1.5 degrees Celsius, or 2.7 degrees Fahrenheit — but only as a complement to the primary goal of aggressively reducing our emissions, and eventually hitting net zero emissions by 2050. The International Panel on Climate Change considers carbon removal to be “unavoidable,” or essential to achieving climate targets, because some industries will be difficult to completely decarbonize, such as agriculture.

That said, there’s a risk of overstating its importance to the public, letting us off the hook from actually having to revolutionize energy production and consumption. Scientists are wary of advocating for geoengineering efforts, like dimming the Sun, for the same reason, even if they do prove necessary.

In any case, progress is meager. According to the report, deliberate human interventions currently remove around 2.2 billion metric tons of Co2 per year, which is about five percent of global annual emissions. The bulk of this is achieved through interventions like planting trees. But novel high tech solutions, such as using machines to suck greenhouse gases straight from the atmosphere — direct air capture — made up just 0.1 percent of that multibillion ton total.
