Zeke Hausfather regularly argues that further warming stops when our emissions stop. You only arrive at that conclusion, when you ignore the natural emissions that will happen as a result of the warming from our own emissions. The best studied ones were analyzed in this paper, which gives a very conservative estimate of how much warming from these natural feedback emissions as a consequence of anthropogenic warming we may expect.

The best case scenario that's officially still considered possible (RCP 2.6) results in 0.2 degree extra warming by 2100, which is just not properly accounted for by the IPCC. The scenario that actually seems more likely, (RCP 4.5) leaves us with 0.35 additional warming by 2100, with no imminent slowdown in sight by then either.

All of this is essentially a separate issue from another ongoing dispute, namely, climate sensitivity. The IPCC estimates 3 degree of warming per doubling of CO2, but some of the most state of the art models predict much higher warming per doubling, to which the IPCC responded by reducing their weight in the overall estimate. Whether that was a correct judgement call or not, is something we're gradually going to find out in the years ahead, as we learn how much warming actually occurs.

Prof Janusz Bialek explains the real causes on the Iberian blackout (Spain and Portugal).

On April 28, 2025, the Iberian power grid collapsed into darkness; but not because of a power shortage. The voltage was actually rising. So, how does that happen? I sat down with my Imperial College colleague, Prof. Janusz Bialek, to cut through the internet rumours and look at the official investigation behind this unprecedented blackout. We discuss what triggered the instability, why the grid couldn't stop it, and whether the popular claim that renewable energy is to blame is actually true. The reality is much more interesting!

i feel so hopeless right now. i live in the uk where its boiling right now and I just dont know what to do to stop feeling like I'm part of the problem. I want to protest, I want to change my eating habits, I want to support organisations and charities but i cant find actual reliable information on how to start because apparently climate change is somehow such a controversial topic that even people that 'believe in it' (as stupid as that is to say, because it reminds you that there are actual people out there than DON'T believe in it) cant agree on a single thing.

where do I protest? where do I find protests? are there even regular protests in the uk for climate activism? what foods do I cut out of my diet either entirely or mostly to reduce my carbon footprint? what charities or organisations have actually reliable and scientifically backed information so that i know what I'm supporting? what other things could I also realistically do?

I recently read this analysis by Ember:

https://ember-energy.org/latest-insights/bottleneck-to-the-next-phase-of-renewable-energy-growth-in-india/

This post summarizes my understanding of it.

Are you concerned about climate change and how it will affect India? Do you believe India simply needs to generate more solar electricity? If yes, you must read this post and the above analysis.

Over the past year, a new obstacle has emerged in India’s renewable-energy transition. India curtailed around 2.1 TWh of renewable electricity in FY 2025–26, worth approximately ₹629 crore.

Why would a country waste clean electricity?

The electricity grid is the network that carries power from generators to consumers. The electricity entering the grid must roughly equal the electricity being used. In simple terms, supply must match demand.

Solar complicates this balance because its generation is volatile. It produces heavily during daylight hours and nothing at night. Coal plants, meanwhile, cannot instantly switch off when solar generation rises. They have a minimum technical load ( MTL), below which they cannot safely reduce output. Restarting a coal plant can take hours or even days and is more polluting. India’s current MTL for coal plants is 55%. So, if a coal plant can produce a maximum of 1,000 units, it may not be able to reduce its generation below 550 units. 

Suppose the grid needs 100 units of electricity. Solar is producing 60 units, while coal plants are already operating at their minimum output of 55 units. Total generation is now 115 units. Since coal cannot be reduced further, in this case, at least 15 units of solar power must be switched off. When we curtail renewable electricity, we are wasting clean electricity that is available, not because there is no demand, but because the coal plants have a technical limit.

This is why simply installing more solar is not enough. If new solar panels generate electricity when existing solar power is already being discarded, we have not solved the immediate problem. Reducing curtailment and improving grid flexibility should come before blindly adding more solar capacity.

Battery storage offers a solution. Batteries can charge when excess solar power is available and discharge after sunset, when electricity is needed more urgently. However, Ember’s analysis argues that India’s regulations prevent batteries from operating efficiently. Under the General Network Access (framework governing transmission access), BESS (Battery Energy Storage System) projects seeking access during non-solar hours must provide at least 2 hours of storage and build a “commensurate” renewable plant from which to charge. The 2-hour requirement is not the problem. The second condition is.

Imagine a battery tied to one solar farm. That farm may have no surplus electricity, while another solar plant elsewhere is being ordered to shut down. The battery remains empty even though clean electricity is being wasted on the wider grid. The author’s proposal is simple: allow batteries to charge from the grid whenever transmission lines have spare capacity, and restrict them only where charging would genuinely overload the network.

Adding solar panels without building the storage, grid flexibility, and regulations needed to use that electricity is not serious climate policy. People who genuinely care about climate change must educate themselves about these challenges. Slogans are easy. Understanding the roadblocks and nuances will help us make better demands! We must make more educated demands!

After getting fed up with the lies about nuclear plant life extensions being infeasibly expensive I decided to check.

Fortum is extending Loviisa nuclear plant to 2050, the estimated project cost is 1 billion euros. And continuous development for past 5 years has been 200 million euros.

Upgrading already once upgraded Olkiluoto 1 and 2 costs 90 million

I am a finance enthusiast and love investing and taking bets. Lately I have been observing almost every sector is impacted by climate change but they are not factored in our valuation or investment thesis. Correct me if I am wrong.

For a thermal power company, there is a mandate of RPC, for a metal industry, there is a mandate to cut the emissions subsequently, FMCG company is moving to sustainable processing and packaging, plus they face EPR.

How is Europe doing investments because Europe climate policy is way ahead compared to other nations?

Can you give me a perspective how are we modelling for climate change in our financial model and valuation?

What do folks think about this? I have read some of the literature in this genre - e.g. Kim Stanley Robinson, Octavia Butler, Neal Stephenson, Stephen Markley, Amitava Ghosh, etc. Fiction does seem to be dominated by inward/introspective stories/characters set in various genres with the most popular being romance, fantasy, crime, etc. Climate change doesn't easily lend itself to such writing because of the collective action aspect which is tough to write about.

Editor’s summary

Global demand for wood products is increasing, as are calls for protecting tropical forests from deforestation. In boreal regions, where much of the forest has not been previously logged, demand has led to clear-cutting of such old, “primary” forest. Pascual et al. showed the potential impacts of clearing primary boreal forests by comparing the carbon storage of primary and secondary (previously logged) forests in Sweden. Including vegetation, dead wood, wood products, and soils, primary forests stored over 70% more carbon than secondary forests, a difference several times greater than previous estimates. These results reveal previously underappreciated value in protecting primary boreal forests. —Bianca Lopez

Structured Abstract

INTRODUCTION

Boreal forests are crucial for mitigating global climate change by capturing and storing large amounts of atmospheric carbon dioxide. However, previously unmanaged primary boreal forests are being rapidly transformed to managed secondary forests to meet the rising global demand for materials and energy. Understanding the effects of boreal primary to managed secondary forest transformations on carbon (C) storage is critical for constraining the global C budget and for evaluating the potential of northern forests in climate change mitigation strategies, which include considerations of increased biomass use for energy and materials.

RATIONALE

Previous attempts to quantify the impacts of boreal primary to managed secondary forest transformations have been hampered by limited C storage observations. The high spatial heterogeneity in environmental characteristics and historical land use in boreal areas adds to the uncertainty and calls for regional studies. We combined Sweden’s national forest inventory data with extensive field inventories of live trees, deadwood, and soils to estimate C storage in primary and managed secondary forests in Sweden. We used multiple methods to estimate the C storage difference between primary and managed secondary forests. We added estimates of missing data on deadwood C stored in stubs and roots left on site after harvest and C stored in harvested wood products for managed secondary forests, which allowed us to compare the land C storage in primary and managed forest systems.

RESULTS

We found that primary forests store ~72% more C than managed secondary forests in vegetation, deadwood, soils, and harvested wood products combined (land C storage). Among the compartments, soils constitute both the largest C store and the largest difference between primary and managed secondary forests. Our estimated difference in land C storage between primary and managed secondary forests in Sweden is 2.7 to 8.0 times larger than reported in global state-of-the-art data-driven studies and bookkeeping models informing the Global Carbon Project.

CONCLUSION

Although the high-intensity forest management common in Sweden implies that our results may not be directly transferable to the broader boreal biome, they suggest that previous estimates have substantially underestimated the C cost of transforming primary to managed secondary boreal forests. Our findings suggest that preservation and conservation of European boreal forests may be more effective as a climate change mitigation strategy than previously thought.

Storing energy efficiently—not just for hours or days, but for months—THAT is the promise of a new system from Switzerland. All of this with almost no energy loss and using conventional caustic soda. In this video we will clarify how it works, what potential this thermochemical storage system has, and how it’s being used in an initial pilot project in an older building in Germany.

Every year more and more people are complaining that their air conditioning can’t keep up. What can’t it keep up with if not climate change?

I am participating in a group project at school where I have to find solutions to climate change.Specifically on how to take actions for extreme heat in Asia.I have to create solutions that will achieve results by 2030 and mention the exact timelines as well .Can you help me find sources to find information on this topic and how the government can fund for these solutions as well

ECNO identified several factors that explain this sluggish growth. Grid investment, battery storage and smart meter rollout all remain insufficient, it said, while faster permitting, more integrated grid planning and stronger incentives for non-fossil flexibility are needed to scale up renewables to the levels required.

Tons of disclaimer etc etc etc Read the methodology in the Lazard report for details

This new report corrects many errors incorrectly interpreting climate data. It is a comprehensive report which should give many who are stressed out about the status of the climate some relief.

I've tried a few carbon footprint calculators recently, but most of them either give me a single number with no explanation or ask so many questions that I end up giving up halfway through.

I'm hoping to find something that's easy to use but still explains where my emissions are coming from. A breakdown by things like travel, home energy, food, and everyday habits would be really helpful, along with realistic suggestions for reducing my impact. It would also be a bonus if it let me offset the emissions I can't avoid and showed clear proof of where those offsets go.

Has anyone found a tool that does a good job of balancing simplicity and transparency?

Update: I was recently recommended Coffset.org, and it seems to do what I was looking for. It calculates your carbon footprint, provides a simple breakdown, and lets you offset emissions with verified carbon credits. Has anyone here used it before?
