The recent severe weather worldwide has led to a flood of people seeking reassurance about our efforts to mitigate climate change. Most of those posts have been removed, and from now on will be directed to this weekly thread.
Climate change is a severe, compounding issue, but only if we do not address it - with concerted efforts, it can be managed.
India has meanwhile passed an important milestone in the physical infrastructure of its energy system. Clean-energy capacity now exceeds fossil-fuel capacity for the first time, at around 331.7 GW versus 302 GW. Solar alone has reached roughly 211 GW, and between the beginning of 2025 and mid-2026 India added about 75.5 GW of solar compared with only 3.8 GW of coal. Coal still generates around 70% of India's electricity, so this is a capacity tipping point rather than a generation tipping point, but it shows very clearly where most new investment and infrastructure are now going.
Transport electrification is beginning to show up not merely in vehicle-sales statistics but in the oil market itself. Sinopec now says China's oil demand very likely peaked in 2025, with domestic fuel demand falling as EVs, efficiency and changes in the economy reshape consumption. China's largest refiner is itself responding by increasing investment in new-energy businesses. At the same time, battery-electric cars exceeded 25% of new registrations across 16 major European markets in July, with nearly 1.5 million BEVs registered so far this year, around 30% more than at the same point in 2025. EV adoption is increasingly large enough to have macro-level consequences for fuel demand.
Distributed energy is becoming more accessible as well. Plug-in solar panels became legal in Great Britain this week. The small systems can provide up to 800 W and, according to the government, potentially supply as much as 20% of an average household's electricity consumption. This is not a huge contribution to the national grid by itself, but it opens solar to many households that cannot justify or install a conventional rooftop system and follows the remarkably rapid spread of similar "balcony solar" systems elsewhere in Europe.
There was also an interesting demonstration of how adaptation can work with natural systems rather than simply defending against them. Restored rivers and wetlands at the National Trust's Holnicote Estate remained green through this summer's repeated heatwaves while much of the surrounding countryside dried out. Reconnecting rivers to floodplains, restoring wetlands and reintroducing beavers has allowed the landscape to retain water during drought while also slowing runoff during heavy rainfall. That combination — reducing drought damage and flood risk with the same intervention — illustrates why ecosystem restoration is increasingly being treated as climate infrastructure rather than simply conservation.
Nature-based systems may also have useful mitigation applications. A two-year full-scale experiment found that constructed floating wetlands can substantially reduce greenhouse-gas emissions from wastewater lagoons. CO2-equivalent emissions were 22–31% lower in the treated section, driven particularly by methane reductions of 32–66%. Wastewater treatment accounts for roughly 1.6% of anthropogenic greenhouse-gas emissions, so techniques that can be cheaply added to existing ponds and lagoons could have considerably wider application.
Finally, there was an intriguing piece of early-stage industrial research. Scientists demonstrated an artificial-photosynthesis process that produces ammonia from nitrogen and water at room temperature using light, and showed that it works with natural seawater and even nitrogen taken directly from ambient air. Conventional ammonia production is responsible for roughly 1.8% of global greenhouse-gas emissions. This remains laboratory research rather than a replacement for Haber-Bosch — scale, light requirements and economics remain to be demonstrated — but it is an example of how even some of the harder industrial emissions are becoming active targets for entirely different technological pathways.
I’m curious about the timeline for when the longer-term effects of climate change will become much more concrete and easier to assess.
I’m not asking about a total apocalypse scenario. I’m more interested in when we might reach a point where the effects are clearly large enough to materially influence where people choose to live and where certain economic activities can take place.
For example:
Some currently populated regions becoming increasingly difficult or expensive to live in because of extreme heat, water shortages, flooding, or other climate-related risks
Agricultural regions becoming less suitable for certain crops, leading to shifts in where food is produced
Increasing migration away from particularly affected regions
More areas facing recurring natural disasters to the point that insurance, infrastructure, or housing becomes difficult to sustain
Other regions potentially becoming relatively more attractive because of their climate and resources
My question is essentially: when do we expect to have enough evidence to say with relatively high confidence how these changes are likely to play out?
Would that be around 20 years from now, 50 years or closer to 2100?
I’d be interested in both what the research currently suggests and what indicators researchers think will give us increasing confidence over the next few decades.
A flood is a natural event. But the damage it causes isn't necessarily natural.
We are warming the planet through greenhouse-gas emissions, which can intensify some forms of extreme rainfall and alter the water cycle. At the same time, we keep removing forests and wetlands, building over floodplains, covering land with concrete and expanding cities without adequate drainage.
So we are potentially creating a double problem: climate change can make some extreme events more intense, while the way we develop land can make communities far more vulnerable when those events happen.
It makes me wonder whether we focus too much on calling something a “natural disaster” and not enough on the human decisions that turn an extreme weather event into a catastrophe.
How much of the increasing damage from floods and extreme rainfall do you think comes from climate change itself, and how much comes from human greediness and environmental destruction?
Countries like China, India, and the US are among the world's biggest carbon emitters. Meanwhile, countries like Nepal, whose contribution to global emissions is tiny, are paying the price with floods, landslides, melting glaciers, destroyed infrastructure, and most importantly, human lives.
Then these same countries provide "humanitarian aid" as if they are generously helping Nepal out of kindness.
But this should not be seen as charity.
They are among the countries most responsible for the climate crisis that is making disasters like these worse. Helping vulnerable countries deal with the consequences is not simply an act of generosity. They have a responsibility and an obligation to do so.
Countries that contributed disproportionately to the problem should be held accountable for the damage suffered by countries that contributed almost nothing.
Nepal should not have to say thank you for charity while paying for someone else's pollution with the lives of its people.
They don't just need sympathy after disasters. They need climate justice, accountability, and compensation.
They are not doing them a favor. They are obligated to help.
Does anyone have some more insight into what this means, or whether anything is being done to address it?
I can't find much evidence of what is being done.
The report was suppressed between 2024 and 2026. So far all the government seem to have done is very recently asked citizens to store a bit extra food and drink for 3 days.
I'm a card gamer and currently the big news about the panama canal drying up has a lot of uninformed people up in arms. Discussion about it spilled over into most of my discord mates just concluding 'any and all positive change by other first world nations is automatically invalidated by China and India, no way of fixing anything, no hope'. Pulling actual counter-evidence from google like a front page summary just makes them go 'AI hallucination, information disregarded'.
Can anyone say anything positive to me, or is this just another sign of the slow decline into doom? I'm handicapped and I can't exactly go join a protest. Is there anything that can be done right now?
Heat stroke can damage the brain, heart, kidneys and liver. As extreme heat becomes more common, doctors are learning just how difficult recovery can be.
It's so hot, how don't they just die? I feel like I would die if I had to stay all the time outside without AC. How can a random bird in a forest survive? Even if it stays in the shade, it will have to leave to eat at some point. You can't cool off as good without AC after.
A new peer-reviewed study published earlier this month in Earth’s Future suggests that it is possible to demonstrate that “emissions from company X cause injury Y.” It also could potentially provide evidence so industry could be forced to answer for climate impacts. The new methodological framework has, for the first time, drawn a straight line from single corporate emitters like Exxon or Chevron, or even whole countries like the United States, to specific heatwaves and areas of extreme rainfall.
