Not exactly news, since this uptick in warming has been a topic of numerous articles. Nonetheless, this is a good summary of why climate scientists are stumped by the higher-than-expected temperatures of 2023.

The world has been its hottest on record for 10 months straight. Scientists can't fully explain why

Leading climate scientists say there is a margin to the extreme heat the world has experienced over the past year that can't be explained by global warming or known climate drivers.

Absent a thread on Resource Abuse, I'll just put this here. Climate change is a contributing factor, even if not the only factor, creating this issue.

Hawaii is "on the verge of catastrophe," locals say, as water crisis continues - CBS News
Despite being surrounded by seemingly endless ocean, freshwater on Oahu, the third-largest of Hawaii's six major islands, is not easily accessible. The island relies on an underground aquifer for its water supply. Replenishing that aquifer is a decades-long natural process, as it takes a single drop of water roughly 25 years to make it there from the sky.

And recent years have seen compounding problems: less rain, leading to significant droughts, and repeated jet fuel leaks and PFAS chemical spills contaminating water systems. All of this significantly limits available water use for locals, many of whom say tourism is only worsening the situation. Just months ago, the world's largest surfing wave pool opened up on the island — filled with freshwater.

Useful for a learner school without the swept out to sea and drowned factor. As happened to a general manager I had.
Okay, that makes sense. But they could have used seawater for it. It saves on precious freshwater, and makes for a more authentic experience.

How climate policies can drive voters to the far right - The Washington Post
More than a decade ago, the Netherlands embarked on a straightforward plan to cut carbon emissions. Its legislature raised taxes on natural gas, using the money earned to help Dutch households install solar panels. By most measures, the program worked: By 2022, 20 percent of homes in the Netherlands had solar panels, up from about 2 percent in 2013. Natural gas prices, meanwhile, rose by almost 50 percent.

But something else happened, according to a new study. The Dutch families who were most vulnerable to the increase in gas prices — renters who paid their own utility bills — drifted to the right. Families facing increased home energy costs became 5 to 6 percent more likely to vote for one of the Netherlands’ far-right parties.

A similar backlash is happening all over Europe, as far-right parties position themselves in opposition to green policies. In Germany, a law that would have required homeowners to install heat pumps galvanized the far-right Alternative for Germany party, or AfD, giving it a boost. Farmers have rolled tractors into Paris to protest E.U. agricultural rules, and drivers in Italy and Britain have protested attempts to ban gas-guzzling cars from city centers.

Scientists scramble as rare rain events in the Arctic trigger issues: 'We are trying to keep up with what is going on' (thecooldown.com)
The effects of rain in the Arctic have been poorly understood, as this is a relatively rare phenomenon that has only begun to be studied recently.

However, in August 2021, rain fell on the summit of the ice cap in Greenland, allowing University of Montana glaciologist Joel Harper to collect data. A huge amount of snow melted and the snow line retreated 2,000 feet, Grist reported.

By comparing the event to previously unexplained data from 2008, Harper was able to determine that the same thing had happened that year, but much later in the autumn. That time, it had rained for four days, while the temperature rose by over 50 degrees.

Supercharged thunderstorms: have we underestimated how climate change drives extreme rain and floods? (theconversation.com)

In media articles about unprecedented flooding, you’ll often come across the statement that for every 1°C of warming, the atmosphere can hold about 7% more moisture.

This figure comes from research undertaken by the French engineer Sadi Carnot and published 200 years ago this year.

We now know there’s more to the story. Yes, a hotter atmosphere has the capacity to hold more moisture. But the condensation of water vapour to make rain droplets releases heat. This, in turn, can fuel stronger convection in thunderstorms, which can then dump substantially more rain.

This means that the intensity of extreme rainfall could increase by much more than 7% per degree of warming. What we’re seeing is that thunderstorms can likely dump about double or triple that rate – around 14–21% more rain for each degree of warming.

While politicians are still busy sabotaging reaching the 1.5C heating target, a recent poll under leading climate scientists shows that they do expect we are heading at least toward a global warming of 2.5C.

“I think we are headed for major societal disruption within the next five years,” said Gretta Pecl, at the University of Tasmania. “[Authorities] will be overwhelmed by extreme event after extreme event, food production will be disrupted. I could not feel greater despair over the future.”

Many also mentioned inequality and a failure of the rich world to help the poor, who suffer most from climate impacts. “I expect a semi-dystopian future with substantial pain and suffering for the people of the global south,” said a South African scientist, who chose not to be named. “The world’s response to date is reprehensible – we live in an age of fools.”

‘I am starting to panic about my child’s future’: climate scientists wary of starting families | Climate crisis | The Guardian
On the debate on the role of population growth in environmental crises, Schipper said: “How many people we have is irrelevant if only a small percentage are doing most of the damage.” Parmesan disagreed, saying the total impact is the combination of people’s level of consumption and the total number of people: “Don’t cherrypick half of the equation and ignore the other half.”
I'm with Parmesan on this issue. We need to decrease both consumption AND population growth. Addressing just one of those key factors is not going to be effective.

IN THE 1920S, gray wolves were systematically eradicated from Yellowstone. But once the wolf population had been eliminated from the park, the number of elk began to grow unchecked. Eventually, herds were overgrazing near streams and rivers, driving away animals including native beavers. Without beavers to build dams, ponds disappeared and the water table dropped. Before long, the entire landscape had changed.


In the 1990s, Yellowstone changed its policy and reintroduced gray wolves into the park. “When those wolves came back in, it was like a wave of green rolled over Yellowstone,” Wood said. This story became one of the defining parables in ecology: Predators weren’t just killers. They were actually holding entire ecosystems together.
