Climate solutions come in all shapes and sizes, and at Yale Climate Connections, we started off the year with the launch of our climate solutions hub, a page designed to help you easily identify climate actions that fit into your life. It’s a great place to find a climate-related New Year’s resolution if that’s your jam. 

To close 2025 out on a high note, check out our favorite solutions stories of the year.

The solar panels Germans are plugging into their walls, by Yale Climate Connections’ radio team

In Germany, people who want to go solar can simply go to the store, buy a solar panel, and plug it in at home. These plug-in solar systems send power directly into a home through a normal wall outlet.

(Sara says, “This development makes solar panels accessible to renters. When it’s time to move, just unplug the panel and carry it to your new apartment.”)

Bill McKibben says cheap solar could topple Big Oil’s power, by Michael Svoboda

There is one big good thing happening on this planet. And that is the sudden surge in the use of what, for the last 40 years, we’ve called alternative energy, but which has now become the most obvious, straightforward way to make power. 

Pearl Marvell, features editor, Yale Climate Connections en español:  


He wasn’t planning to step in – until his team informed him that some immigrant enclaves were still waiting on help a month after the storm. They brainstormed a list of what families must need as winter approached: coats, heaters, blankets, generators, food, cash. When they began distributing items, many told the group that theirs was the first to offer them help.

(Pearl says, “I love this article because Yessenia wrote this story so beautifully and focused it primarily on how this community came together to help each other in times of need. I love when we can tell stories that are people-focused and then backed up by science.)

The rest of the world is lapping the U.S. in the EV race, by Dana Nuccitelli

According to an analysis by the International Council on Clean Transportation, climate pollution from global road transportation may have peaked in 2025 thanks to accelerating EV deployments around the world.

(Pearl says, “Because at least the rest of the world is going in the right direction.”)

How to steer EVs towards the road of ‘mass adoption’

Posted on 5 January 2026 by Guest Author

This is a re-post from Carbon Brief by Izzy Woolgar, director of external affairs at the Centre for Net ZeroAndy Hackett, senior policy adviser at the Centre for Net Zero; and Laurens Speelman, principal at the Rocky Mountain Institute

Electric vehicles (EVs) now account for more than one-in-four car sales around the world, but the next phase is likely to depend on government action – not just technological change.

That is the conclusion of a new report from the Centre for Net Zero, the Rocky Mountain Institute and the University of Oxford’s Environmental Change Institute.

Our report shows that falling battery costs, expanding supply chains and targeted policy will continue to play important roles in shifting EVs into the mass market.

However, these are incremental changes and EV adoption could stall without efforts to ensure they are affordable to buy, to boost charging infrastructure and to integrate them into power grids.

Moreover, emerging tax and regulatory changes could actively discourage the shift to EVs, despite their benefits for carbon dioxide (CO2) emissions, air quality and running costs.

This article sets out the key findings of the new report, including a proposed policy framework that could keep the EV transition on track.

A global tipping point

Technology transformations are rarely linear, as small changes in cost, infrastructure or policy can lead to outsized progress – or equally large reversals. 

The adoption of new technologies tends to follow a similar pathway, often described by an “S-curve”. This is divided into distinct phases, from early uptake, with rapid growth from very low levels, through to mass adoption and, ultimately, market saturation.

However, technologies that depend on infrastructure display powerful “path-dependency”, meaning decisions and processes made early within the rollout can lock in rapid growth, but equally, stagnation can also become entrenched, too.

EVs are now moving beyond the early-adopter phase and beginning to enter mass diffusion. There are nearly 60m on the road today, according to the International Energy Agency, up from just 1.2m a decade ago. 

Technological shifts of this scale can unfold faster than expected. Early in the last century in the US, for example, millions of horses and mules virtually disappeared from roads in under three decades, as shown in the chart below left.

Yet the pace of these shifts is not fixed and depends on the underlying technology, economics, societal norms and the extent of government support for change. Faster or slower pathways for EV adoption are illustrated in the chart below right.

Left: The S-curve from horses to cars.Left: The S-curve from horses to cars. Right: The predicted shift from ICE to EVs. Note that S-curves present technology market shares from fixed saturation levels to show the shape of diffusion, rather than absolute numbers; Cars were both a substitute for, and additional to, horses.

Posted on 4 January 2026 by BaerbelW, Doug Bostrom

A listing of 28 news and opinion articles we found interesting and shared on social media during the past week: Sun, December 28, 2025 thru Sat, January 3, 2026.

Year 2025 Statistics

As this is the first news roundup of 2026 and we therefore have the complete year 2025 "in the can", we thought that you might enjoy some stats about what we shared during the previous 12 months.

All told, we shared 1470 links from about 270 different outlets, the vast majority of which provided fewer than 10 links and the bulk of shares originated from just 25 different outlets. The Top10 are: The Guardian (190), Skeptical Science (164), Inside Climate News (108), Yale Climate Connections (67), Phys.org (63), Carbon Brief (58), New York Times (54), The Conversation (52), Grist (47), CNN (38), followed by The Climate Brink, The Washington Post, DeSmog, Climate Home News and NPR. Among the shares are also 53 links to Youtube videos from different creators like ClimateAdam, "Just have a think", Dr Gilbz or Potholer54.

Skeptical Science New Research for Week #1 2026

Posted on 1 January 2026 by Doug Bostrom, Marc Kodack

Open access notables

A desk piled high with research reports

Editorial: Surviving the Anthropocene: the 3 E’s under pressing planetary issues, Sanita Lima et al., Frontiers in Ecology and Evolution

Scientists, including stratigraphists, all agree that our species has changed planet Earth in unprecedented ways. But contention exists around the actual start date and the diachronicity of the global human impact (Boivin et al., 2024). Indeed, the term “Anthropocene” is not the first attempt to name the consequences of human activities on our planet (Steffen et al., 2011), and several starting dates for the Anthropocene (from the emergence of the human species to the Great Acceleration and nuclear tests) have been eloquently defended (Logan, 2022). Furthermore, given the social and monetary aspects of the Anthropocene, terms like Capitalocene have been proposed as well (Moore, 2016). As highlighted in this Research Topic, López-Corona and Magallanes-Guijón introduce the concept of Technocene and explain why human technology must take a central place in the definition of our current period. Interestingly, the existence of so many terms trying to explain our impact on Earth could already be an indicator that we are, in fact, in a moment at which human interference is changing Earth’s natural history.

Relationships between climate change perceptions and climate adaptation actions: policy support, information seeking, and behaviour, van Valkengoed et al., Climatic Change

People are increasingly exposed to climate-related hazards, including floods, droughts, and vector-borne diseases. A broad repertoire of adaptation actions is needed to adapt to these various hazards. It is therefore important to identify general psychological antecedents that motivate people to engage in many different adaptation actions, in response to different hazards, and in different contexts. We examined if people’s climate change perceptions act as such general antecedents. Questionnaire studies in the Netherlands (n = 3,546) and the UK (n = 803) revealed that the more people perceive climate change as real, human-caused, and having negative consequences, the more likely they are to support adaptation policy and to seek information about local climate impacts and ways to adapt. These relationships were stronger and more consistent when the information and policies were introduced as measures to adapt to risks of climate change specifically. However, the three types of climate change perceptions were inconsistently associated with intentions to implement adaptation behaviours (e.g. installing a green roof). This suggests that climate change perceptions can be an important gateway for adaptation actions, especially policy support and information seeking, but that it may be necessary to address additional barriers in order to fully harness the potential of climate change perceptions to promote widespread adaptation behaviour.

From this week's government/NGO section:

Unequal evidence and impacts, limits to adaptation: Extreme Weather in 2025Otto et al., World Weather Attribution

Every December we are asked the same question: was it a bad year for extreme weather? And each year, the answer becomes more unequivocal: yes. Fossil fuel emissions continue to rise, driving global temperatures upward and fueling increasingly destructive climate extremes across every continent. Although 2025 was slightly cooler than 2024 globally, it was some of the worst extreme weather events of 2025 that were studied, documenting the severe consequences of a warming climate and revealing, once again, how unprepared people remain. Across the 22 extreme events that are analyzed in depth, heatwaves, floods, storms, droughts and wildfires claimed lives, destroyed communities, and wiped-out crops. Together, these events paint a stark picture of the escalating risks we face in a warming world

Counting the Cost 2025. A year of climate breakdownJoe Ware and Oliver Pearce, Christian Aid

The authors identify the 10 most expensive and impactful climate disasters of 2025. The year 2025 was marked by a series of devastating climate events, from heatwaves that pushed the limits of human survival, to record-breaking hurricanes that overwhelmed disaster response systems, and catastrophic rainfall and droughts that wreaked havoc on vulnerable communities. The report underscores the escalating cost of climate change, with fossil fuel companies playing a central role in driving the crisis. The cost of climate inaction is equally clear, as communities continue to bear the brunt of a crisis that could have been averted with urgent action to reduce greenhouse gas emissions.

2025 Climate SurveyThe National Institute for Climate and Environmental Policy at Ben-Gurion University of the Negev

Levels of concern about the impacts of climate change are high across the public, but readiness to change lifestyles is low, especially when it involves personal sacrifice. The data indicate that religious affiliation explains climate attitudes in Israel more strongly than political affiliation.

Direct Air Capture

Posted on 30 December 2025 by Ken Rice

This is a re-post from And Then There's Physics

I thought I’d written about this before, but can’t seem to find a post. Either, my searching ability is poor, or my memory is poor. I mostly wanted to highlight an interesting YouTube video by David Kipping that illustrates why Direct Air Capture (DAC) is thermodynamically challenging. I encourage you to watch the video (which I’ve put at the end of this post) but his basic conclusion is that thermodynamic constraints mean that implementing DAC at the necessary scale would require a significant fraction of all global electricity consumption.

I wanted, however, to work through some of the numbers myself and to do the calculation of how much DAC we would need to use in a slightly different way.

A key point is that given an atmospheric concentration of 400 ppm and a temperature of 300K, it takes a minimum of 19505 J to remove 1 mole of CO2. 1 mole of CO2 is 44g, so 1 tonne of CO2 has 22727 moles. Therefore, removing 1 tonne of CO2 requires a minimum of 4.43 x 108 J.

Typically, however, we emit so much that we tend to think in terms of gigatonnes of CO2 (GtCO2). Removing 1 GtCO2 would require a minimum of 4.43 x 1017 J.

IEA: Declining coal demand in China set to outweigh Trump’s pro-coal policies

Posted on 29 December 2025 by Guest Author

This is a re-post from Carbon Brief by Josh Gabbatiss

China’s coal demand is set to drop by 2027, more than cancelling out the effects of the Trump administration’s coal-friendly policies in the US, according to the International Energy Agency (IEA).

Global coal demand is due to grow by 0.5% year-on-year to reach record levels in 2025, according to the latest figures in the IEA’s annual market report.

Yet this will be reversed over the next couple of years, as a faster-than-expected expansion of renewables in key Asian nations and “structural declines” in Europe push coal demand down, the agency says.

While US coal demand is set to continue falling, the decline will be slower than expected last year, due to new federal government efforts to support the fuel. 

However, the IEA’s upward revision of an extra 38m tonnes (Mt) of US coal use in 2027 is dwarfed by an even larger 126Mt downward revision in China’s coal use.

‘Unusual trends’

Coal demand will reach 8,845Mt around the world in 2025. This is slightly (44Mt) higher than the IEA had forecast in its 2024 coal market report.

The agency notes some “unusual regional trends” impacting this growth, including a 37Mt year-on-year increase in US coal demand in 2025 to 516Mt. This is 59Mt (17%) higher than the IEA projected in 2024.

A new suite of measures under the Trump administration have supported the short-term use of coal, including the modernisation of existing coal plants and reopening shuttered ones.

EU coal use declined at a slower pace than expected due to lower wind and hydropower output, according to the IEA. Nevertheless, the bloc “continues its structural decline” in coal demand, driven by renewables expansion, carbon pricing and coal phaseout pledges.

India saw an unexpected dip in coal consumption in 2025, linked to a strong monsoon season that increased hydropower output and curbed electricity demand.

In China, which accounts for more than half of the world’s coal use, coal demand remained roughly unchanged between 2024 and 2025, the IEA says.
