Learning how to weave! After a brief attempt at card weaving, I discovered pick-up weaving and immediately switched over to weaving with a heddle. And since I need to make everything as complicated as possible, I'm working on creating my own patterns as I learn.

"The cleanest sources of electricity could soon make up the largest share of electricity generation in the European Union. Wind and solar made huge strides last year, producing more than one-quarter of the EU’s electricity for the first time, while fossil fuel generation plummeted. Power-sector emissions fell by a record 19 percent in the region last year.

According to Ember’s European Electricity review, this record-setting level of renewable energy was mostly driven by growth in solar and wind, which each saw their largest-ever capacity additions.

Solar electricity generation grew by 36 terawatt-hours in 2023, reaching 9 percent of the EU’s total electricity generation. But wind is leading the energy transition in Europe. In 2023, the region added 55 TWh of wind, growing to 18 percent of generation and, in a major milestone, surpassed gas generation for the first time.

European countries also saw examples of renewables-heavy power systems working reliably last year. In May, Spain ran on 100 percent renewables for nine hours; in October, Greece did the same for five hours. In November, Portugal ran on 100 percent renewables for 149 hours — or six days in a row.

Hydropower and nuclear generation also rebounded from lows in 2022, pushing overall carbon-free electricity to more than two-thirds of the EU’s electricity makeup. Over the same timeframe, fossil fuel generation fell by a record 19 percent. It now generates just one-third of the region’s power. Coal plummeted by a record 26 percent last year as more plants shuttered, while gas — which has been declining for the past four years — also saw a sharp 15 percent drop.

Looking ahead, the power sector will need to nearly double the current share of renewable generation if it is to keep up with both emissions-reduction goals and the EU’s legally mandated Renewable Energy Directive. The latter requires all member states to produce at least 42.5 percent of their power from renewables by 2030. In other words, the upward trajectory of renewables in Europe is going to keep growing."

A new study shows that economic growth rates make a big difference when it comes to prospects for limiting global warming to 1.5°C, as per the Paris Agreement. A recent study by the Institute for Environmental Science and Technology of the Universitat Autònoma de Barcelona (ICTA-UAB) shows that pursuing higher economic growth may jeopardize the Paris goals and leave no viable pathways for humanity to stabilize the climate. On the contrary, slower growth rates make it more feasible to achieve the Paris goals.

The study demonstrates that global economic growth of 4% per year, which is currently assumed in the mitigation scenarios, is incompatible with the goals of the Paris Agreement even if the most ambitious mitigation plans of any major country were implemented globally. "To reduce global emissions fast enough to limit warming to 1.5°C, we find it is necessary to pursue ambitious mitigation and shift away from growth. Even with highly ambitious mitigation, global economic growth would need to fall below the recent historical trend of ⁓2% per year, with high-income economies transitioning to post-growth," says Aljoša Slameršak, ICTA-UAB researcher and lead author of the study.

"Two and a half years ago, when I was asked to help write the most authoritative report on climate change in the United States, I hesitated...

In the end, I said yes, but reluctantly. Frankly, I was sick of admonishing people about how bad things could get. Scientists have raised the alarm over and over again, and still the temperature rises. Extreme events like heat waves, floods and droughts are becoming more severe and frequent, exactly as we predicted they would. We were proved right. It didn’t seem to matter.

Our report, which was released on Tuesday, contains more dire warnings. There are plenty of new reasons for despair. Thanks to recent scientific advances, we can now link climate change to specific extreme weather disasters, and we have a better understanding of how the feedback loops in the climate system can make warming even worse. We can also now more confidently forecast catastrophic outcomes if global emissions continue on their current trajectory.

But to me, the most surprising new finding in the Fifth National Climate Assessment is this: There has been genuine progress, too.

I’m used to mind-boggling numbers, and there are many of them in this report. Human beings have put about 1.6 trillion tons of carbon in the atmosphere since the Industrial Revolution — more than the weight of every living thing on Earth combined. But as we wrote the report, I learned other, even more mind-boggling numbers. In the last decade, the cost of wind energy has declined by 70 percent and solar has declined 90 percent. Renewables now make up 80 percent of new electricity generation capacity. Our country’s greenhouse gas emissions are falling, even as our G.D.P. and population grow.

In the report, we were tasked with projecting future climate change. We showed what the United States would look like if the world warms by 2 degrees Celsius. It wasn’t a pretty picture: more heat waves, more uncomfortably hot nights, more downpours, more droughts. If greenhouse emissions continue to rise, we could reach that point in the next couple of decades. If they fall a little, maybe we can stave it off until the middle of the century. But our findings also offered a glimmer of hope: If emissions fall dramatically, as the report suggested they could, we may never reach 2 degrees Celsius at all.

For the first time in my career, I felt something strange: optimism.

And that simple realization was enough to convince me that releasing yet another climate report was worthwhile.

Something has changed in the United States, and not just the climate. State, local and tribal governments all around the country have begun to take action. Some politicians now actually campaign on climate change, instead of ignoring or lying about it. Congress passed federal climate legislation — something I’d long regarded as impossible — in 2022 as we turned in the first draft.

[Note: She's talking about the Inflation Reduction Act and the Infrastructure Act, which despite the names were the two biggest climate packages passed in US history. And their passage in mid 2022 was a big turning point: that's when, for the first time in decades, a lot of scientists started looking at the numbers - esp the ones that would come from the IRA's funding - and said "Wait, holy shit, we have an actual chance."]

And while the report stresses the urgency of limiting warming to prevent terrible risks, it has a new message, too: We can do this. We now know how to make the dramatic emissions cuts we’d need to limit warming, and it’s very possible to do this in a way that’s sustainable, healthy and fair.

The conversation has moved on, and the role of scientists has changed. We’re not just warning of danger anymore. We’re showing the way to safety.

I was wrong about those previous reports: They did matter, after all. While climate scientists were warning the world of disaster, a small army of scientists, engineers, policymakers and others were getting to work. These first responders have helped move us toward our climate goals. Our warnings did their job.

To limit global warming, we need many more people to get on board... We need to reach those who haven’t yet been moved by our warnings. I’m not talking about the fossil fuel industry here; nor do I particularly care about winning over the small but noisy group of committed climate deniers. But I believe we can reach the many people whose eyes glaze over when they hear yet another dire warning or see another report like the one we just published.

The reason is that now, we have a better story to tell. The evidence is clear: Responding to climate change will not only create a better world for our children and grandchildren, but it will also make the world better for us right now.

Eliminating the sources of greenhouse gas emissions will make our air and water cleaner, our economy stronger and our quality of life better. It could save hundreds of thousands or even millions of lives across the country through air quality benefits alone. Using land more wisely can both limit climate change and protect biodiversity. Climate change most strongly affects communities that get a raw deal in our society: people with low incomes, people of color, children and the elderly. And climate action can be an opportunity to redress legacies of racism, neglect and injustice.

I could still tell you scary stories about a future ravaged by climate change, and they’d be true, at least on the trajectory we’re currently on. But it’s also true that we have a once-in-human-history chance not only to prevent the worst effects but also to make the world better right now. It would be a shame to squander this opportunity. So I don’t just want to talk about the problems anymore. I want to talk about the solutions. Consider this your last warning from me."
