Above 2,732°F (1,500°C), conventional insulation materials start to degrade or convey excessive heat. With applications in advanced manufacturing, energy, and aerospace, this discovery has the potential to transform how industries manage extremely hot conditions.

What Makes This Carbon Nanotube Insulation Different from Existing Materials?

The super-aligned new carbon nanotube insulation withstands extreme heat and is used to create the novel-designed insulation. Like plucking silk threads, researchers cultivate vertical arrays of nanotubes before “drawing” them into thin sheets. The material’s remarkable qualities come from the way these sheets are coiled or stacked to create multilayered, porous structures.

As new carbon nanotube insulation withstands extreme heat, the following are essential characteristics that set this material apart:

Extremely low heat conductivity:

• At room temperature, 0.004 W/mK.
• At 2,600°C, 0.03 W/mK is significantly lower than that of typical insulators, such as graphite felt.

Lightweight density:

• Ranges from 5 to 100 kg/m³, making it simple to incorporate into the aircraft industry and other sectors where weight is essential.

Heat resistance:

• Able to withstand hundreds of heating/cooling cycles and extremely high temperatures.

Blocking radiation:

• Infrared light is absorbed and dispersed by nanotubes, which trap thermal photons.

Scalability:

• It is possible to create sheets that are up to 550 mm broad and maybe hundreds of meters long.

The new material has the potential to be revolutionary due to its stability, performance, and scalability.

How Does It Block Heat Transfer So Effectively?

Dissecting the three primary methods of heat transfer—radiation, convection (gas conduction), and conduction—helps explain the discovery.

Conduction through solids:

• Heat must pass through several layers due to the arrangement of the nanotubes rather than along the tubes.
• Heating vibrations, or phonons, have a hard time passing through each tube since they are just 10–20 nanometers in diameter and separated by space.

Gas conduction:

• Gas molecules cannot readily move through the little holes.
• Instead, they lose energy and bounce within (the Knudsen effect), which lowers conduction.

Radiation:

• At high temperatures, radiation predominates because photons carry heat.
• Because of their electronic structure (van Hove singularities), nanotubes have a significant absorption and scattering of infrared radiation.
• Layers stacked at different angles trap radiation, which significantly lowers heat transfer.

Said, this insulation is significantly more effective than conventional materials since it stops heat in all directions.

Airspace:

• Shielding for spacecraft reentry.
• Protection for airplanes operating at hypersonic speeds.
• Thermal barriers in jet engines.

Energy:

• Reactors that use fusion.
• Nuclear power plants.
• Gas turbines with high temperatures.

Industrial manufacturing:

• Smelters, furnaces, and kilns.
• Insulation that is lightweight for industrial procedures that involve high temperatures.

Electronics:

• Thermal control is crucial in situations where heat resistance and space are essential.
• The material’s ability to wrap around uneven surfaces and its flexibility enhance its practical usage.

What Challenges Still Need to Be Solved?

Despite the potential, several obstacles must be overcome before the insulation is widely used:

• Oxidation resistance: At high temperatures, carbon nanotubes can break down in oxygen. To make sure the material endures in outdoor settings, researchers intend to apply protective coatings.
• Cost and scalability: While vast sheets may be made, consistent quality and a reduction in production costs are necessary for widespread industrial adoption.
• Durability under stress: Materials used in the energy and aerospace sectors must be able to withstand mechanical stress, chemical exposure, and high temperatures. Long-term research will be required.

Nanotube insulation has the potential to be one of the most significant materials of the upcoming generation if these issues are resolved.

Can India Mobilize $467 Billion Without Harming Its Economy?

Whether such a significant investment could cause India’s economy to become unstable is a prevalent worry. After conducting a macroeconomic consistency check, the study concludes that raising the money won’t have an adverse effect on inflation or competitiveness.

Private Sector Role

• A large portion of the funds can be raised domestically through green technology incentives and public-private partnerships.
• Private investments can be directed toward sustainable projects through the use of green bonds and blended financing instruments.

International Climate Finance

• India has repeatedly emphasized the necessity for outside assistance. Although the Paris Agreement calls for rich countries to contribute to climate financing, the flows are still insufficient.
• The burden might be lessened if a share of the $100 billion yearly climate funding pledge is secured.

Economic Absorption Capacity

• The authors contend that the Indian economy may absorb this investment without impairing export competitiveness.
• Investing in green infrastructure is likely to boost innovation, reduce future climate risks, and create millions of jobs.

What is Osmotic Power?

Osmotic power is generated when freshwater and saltwater interact across a semipermeable membrane. The natural flow of freshwater toward saltier water creates pressure, which can be harvested to spin turbines and generate electricity. The idea was first explored in the 1970s, but high costs and inefficient membranes slowed progress.

Recent technological advances have revived the field. Today’s membranes are far more efficient and cost-effective, and research demonstrates that osmotic energy can reliably provide baseload electricity, a steady output available around the clock. This makes it an ideal complement to intermittent renewables like solar and wind. In addition, it is emission-free and based on abundant natural resources, making it a uniquely sustainable option.

How Does Osmotic Power Generation Work?

The principle is simple: water moves from low salinity (freshwater) to high salinity (seawater) through a selective membrane. In Pressure-Retarded Osmosis (PRO), this movement builds pressure that drives a turbine.

Modern breakthroughs include:

• Sweetch Energy’s INOD® membranes, built with biomaterials and nanoscale pores (~10 nm), deliver power densities of 20–25 watts per square meter (W/m²) compared to just 1 W/m² in earlier membranes.
• Biomaterial construction slashes costs to one-tenth of previous technologies, solving a critical barrier.

Because the process returns water with only slight salinity changes, its ecological footprint is minimal.

What are the Latest Breakthroughs?

Several innovations are accelerating commercialization:

• Sweetch Energy, named a World Economic Forum 2025 Technology Pioneer, raised €25 million in early 2024 to deploy osmotic projects in France.
• In partnership with Rockwell Automation, Sweetch has automated plant operations in the Rhône delta, paving the way for scalable facilities of up to 500 MW capacity—enough for 1.5 million people.
• SaltPower in Denmark has turned to geothermal brines, which offer higher salinity and greater energy yield.

With advances in nanofluidics, anti-fouling materials, and durability testing, osmotic power has moved from experimental prototypes to realistic commercial ventures.

Clean Energy Progress: A Silver Lining

Despite rising fossil fuel emissions, there are encouraging signs for the global clean energy transition:

• Renewables boom: In 2024, renewables supplied over 40% of global electricity, mainly from solar and wind.
• Power sector cuts: Global coal emissions decreased by 11%, while oil emissions fell by 0.3%.
• India’s power sector: Emissions down 0.8% in the first half of 2025.
• China’s power sector: Emissions down 1.7%.

Figure: Global Wind and Solar Power Generation. Source: Ember

Still, challenges remain:

• Investment in global clean energy and low-emission fuels is expected to reach a record in 2025, but at under $30 billion, it remains far below the required amount.
• According to the World Economic Forum’s 2025 Energy Transition Index, 65% of nations are making progress; however, financing gaps and risks related to energy security persist.

Most importantly, the IPCC cautions that to keep global warming to 1.5°C, emissions must peak by 2025 and decrease by 43% by 2030. Current trajectories suggest this target is slipping out of reach.

• There are still 180 people awaiting relocation.
• In low-lying areas, 10,000 people are still immediately affected.

Among the actions taken by the government were:

• 13 regulator drains must be closed to prevent backflow.
• Coordinating the water discharge from the Okhla Barrage with Uttar Pradesh officials.
• In relief camps, pesticides are sprayed to prevent the spread of diseases carried by mosquitoes.

To remove stranded families, rescue crews from the fire department, police, and NDRF have been working nonstop. In locations like Madanpur Khadar, Jaitpur, and Badarpur, people waded through neck-deep water while carrying goods on their heads.

Impact on Daily Life

Normal life in Delhi came to a complete halt due to the floods:

• Shops & Livelihoods: Companies were destroyed in Majnu-ka-Tila. Long-term repair expenses and damaged merchandise were reported by store owners like Anup Thapa.
• Housing: Families in Jhuggi, or informal settlements, were forced to live on the side of the road under plastic sheets after losing their homes.
• Animals: From submerged areas, activists saved stray dogs, including ones that were pregnant and injured.
• Traffic Chaos: In anticipation of severe traffic, Delhi Police issued advisories with detours from Majnu-ka-Tila to Salimgarh By-Pass.

Looking Ahead

The Yamuna may continue to rise after the Hathnikund Barrage releases more than 1.68 lakh cusecs of water. The worst could not be over, according to authorities. Traffic detours, relief camps, and other cremation locations are short-term solutions, but the city’s flood control issues are long-term.

Devastating floods have struck Delhi in 1978, 2010, 2013, and 2023; the floods of 2025 are yet another warning that millions of people remain at risk due to climate extremes and inadequate riverfront planning.

A team of international researchers studied more than a billion social media posts from 157 countries. They discovered that when temperatures soar above 95°F (35°C), people’s online posts become more negative. In low-income countries, negative moods increase by 25 percent, while in wealthier countries, the increase is about 8 percent.

The findings remind us that climate change is not just about the planet’s physical environment. It is also about how humans feel, cope, and interact with each other in a warming world.

Study at a Glance: 1.2 Billion Posts, 157 Countries, 65 Languages

This groundbreaking study, published in the journal One Earth, provides the first global look at how rising temperatures affect human emotions. Led by researchers from MIT’s Sustainable Urbanization Lab, Chinese Academy of Sciences, Harvard University, Maastricht University, Duke University, and the Laureate Institute for Brain Research, the project analyzed 1.2 billion social media posts made in 2019.

The team used Twitter and Weibo data written in 65 different languages across 157 countries. Each post was assigned a sentiment score between 0.0 (very negative) and 1.0 (very positive) using advanced natural language processing (NLP). The technique, called BERT (Bidirectional Encoder Representations from Transformers), allowed the researchers to detect subtle emotional tones across cultures and languages.

The posts were then matched with local weather data from 2,988 global locations, creating a massive dataset that links daily temperature swings to human moods.

Income Gap in Emotional Impact: Poorer Nations 3x More Affected

The study used the World Bank income cutoff of $13,845 per person per year to separate higher-income countries from middle-to-lower-income countries. This clear divide showed how economic conditions amplify climate stress.

On days hotter than 95°F (35°C):

• In low- and middle-income countries, expressed sentiments were 25% more negative.
• In wealthier countries, expressed sentiments were 8% more negative.

Why the gap? Researchers suggest that poorer countries often lack widespread air conditioning, cooling centers, or adaptive infrastructure. People in these regions may also work longer hours outdoors and have fewer ways to shield themselves from heat stress.

As researcher Yichun Fan explains: “Thanks to the global coverage of our data, we find that people in low- and middle-income countries experience sentiment declines from extreme heat that are three times greater than those in high-income countries.”

This shows why global climate policy must prioritize adaptation strategies in poorer regions. These communities not only face higher physical risks from extreme heat but also carry a heavier emotional toll.

Why Does Social Media Matter?

Traditional surveys can’t capture emotional shifts at this scale. But social media offers a real-time window into how billions of people feel daily.

Lead author Jianghao Wang points out: “Social media data provides us with an unprecedented window into human emotions across cultures and continents. This approach allows us to measure emotional impacts of climate change at a scale that traditional surveys simply cannot achieve.”

By analyzing posts, researchers can track emotional health at a planetary level and see how climate stress plays out across societies.

Emotional Well-Being in 2100 Could Worsen by 2.3%

The study did not stop with present-day analysis. Using long-term climate models, the team projected how heat-related mood declines might play out by the year 2100.

Assuming continued warming and some level of adaptation, they predict a 2.3% decline in global emotional well-being linked to rising heat. While that number may sound small, it reflects a planet-wide average. In reality, many communities, especially in low-income regions, could face much sharper declines.

Researcher Nick Obradovich adds, “It’s clear now that weather alters sentiment on a global scale. And as weather and climates change, helping individuals become more resilient to shocks to their emotional states will be an important component of overall societal adaptation.”

Climate Change and Human Well-Being

This research connects climate change to everyday emotional well-being. While earlier studies have focused on physical health or economic productivity, this work reveals how our moods and mental states are also at risk.

Professor Siqi Zheng of MIT sums it up: “Our study reveals that rising temperatures don’t just threaten physical health or economic productivity, they also affect how people feel, every day, all over the world.”

This creates a powerful argument for addressing climate change not only as an environmental or economic challenge but as a human well-being crisis.

Climate Change Related Mood and Mental State Changes

What Policymakers Can Do

The findings highlight the urgent need for:

• Adaptation strategies in poorer countries, such as better cooling infrastructure and urban design.
• Public health programs aim to help communities cope with heat stress, both emotionally and physically.
• Policy frameworks that treat emotional well-being as part of climate resilience.

The authors hope that making their global dataset public will help governments, researchers, and communities prepare better for a warming world.

Conclusion

The study makes one fact clear: rising temperatures linked to increased negative moods affect people all around the globe. And while everyone feels the strain, poorer countries carry the heaviest burden.

By 2100, global emotional well-being could decline by about 2.3% due to extreme heat alone. That’s a sobering reminder that climate change is not just about storms or rising seas; it is about how billions of people feel and function every single day.

As the researchers stress, preparing for a hotter future means building not just stronger infrastructure but also stronger emotional resilience. The science now shows that climate change is deeply personal, touching our minds as much as our environment.

And if we want a healthy future, we must act on both. After all, rising temperatures linked to increased negative moods are a challenge we can’t afford to ignore.

FAQs

1. How do rising global temperatures affect human moods?

Studies show that higher temperatures are linked to irritability, aggression, reduced concentration, and increased risk of depression and anxiety. Heat stress disrupts sleep, elevates stress hormones, and can trigger mood swings.

2. Is there scientific evidence linking heatwaves to mental health issues?

Yes. Research published in journals like Nature Climate Change and The Lancet shows a direct correlation between heatwaves and spikes in hospital admissions for mental health conditions, including mood disorders and substance use crises.

3. Why do hot temperatures cause irritability or aggression?

High heat strains the body’s ability to regulate itself, leading to dehydration, poor sleep, and hormonal imbalances. This physiological stress often translates into frustration, irritability, or aggressive behavior.
