The Intergovernmental Panel on Climate Change (IPCC) has unleashed their Special Report on the impact of global warming reaching 1.5°C above pre-industrial levels.
“This IPCC report is set to outline a rescue plan for humanity,”
“1.5°C is the new 2°C,”
If we stick to Paris Climate Agreement commitments, we could still see a global warming of about 3°C by 2100.

Analyysi: Olen tehnyt 40-vuotisen uran enkä ole koskaan uutisoinut näin merkittävää asiaa ilmastonmuutoksesta
Kiinassa hiilidioksidipäästöt ovat kääntyneet laskuun. Se merkitsee sitä, että koko maailman päästöt ovat tasoittuneet tai jopa vähentyneet, kirjoittaa tiedettä seuraava toimittaja Heikki Ali-Hokka.

US firm targets 100 billion gallon of jet fuel reduction with green alternative
LanzaJetTM Alcohol-to-Jet (AtJ) technology is able to create SAF and renewable diesel from waste-based and sustainable ethanol sources.
https://interestingengineering.com/transportation/ethanol-plant-begin-jet-fuel-production?fbclid=IwY2xjawLpWIVleHRuA2FlbQIxMQABHshmVTZKPJq0pRTVia_1DBXRXBuyXLTC8xCMqVUm5CMSZF2boqVZCqz0zee9_aem_omVUVEE-CYdRUr5lQQUbHw
Chicago-based company is soon expected to kick off production of sustainable aviation fuel (SAF) from ethanol for planes. LanzaJet’s facility in rural Soperton, Georgia, is likely to begin production by the end of this year, according to a report.
The USD200 million plant is the world’s first factory designed to make commercial green jet fuel from ethanol. The facility is reportedly expected to reduce the consumption of 100 billion gallons of jet fuel, which the global aviation sector consumes in a year.
The Sustainable Aviation Fuel (SAF) is compatible with existing aircraft and infrastructure. SAF is catalyzing a new industry — redefining fuel production, energy security, and rural economic development.
Facility to help decarbonize the aviation industry
Earlier, the plant was scheduled to start commercial production in 2024. Jimmy Samartzis, LanzaJet CEO, has recently revealed that the delay in the start of production was linked to equipment issues.
The facility is expected to help decarbonize the aviation industry for a greener future. The leading alternative fuels technology company had patented ethanol-based alcohol-to-jet (ATJ) technology.
SAF is produced using any low-carbon ethanol
LanzaJet claims that the SAF is produced using any low-carbon ethanol, such as energy crops, municipal solid waste, carbon captured from industrial processes, renewable energy and more.
The fuel can be used with all existing airline infrastructure, engines, and equipment. It meets or exceeds ASTM D7566 Annex A5 jet fuel specifications. It also has a higher energy density than traditional jet fuel.
The SAF significantly reduces emissions and has been proven to reduce an airplane’s contrails and particulate matter by up to 95%.
“Through the use of our patented LanzaJetTM Alcohol-to-Jet (AtJ) technology, we are able to create SAF and renewable diesel from waste-based and sustainable ethanol sources. These sources include ethanol created from feedstocks such as low-carbon sugarcane, energy crops, forest residuals, agricultural wastes, and organic waste, just to name a few,” said the company in a statement earlier.

Metsien hakkuiden rajoittaminen ei takaa tarvittavia hiilinieluja, Luonnonvarakeskuksen tutkimusprofessorit arvioivat.
Leinonen painottaa, että metsien hiilensidontakyky heikkenee vanhetessaan.
Leinosen mukaan huomion tulisi olla esimerkiksi päästövähennystoimissa liikenteessä ja turvemailla.
Hallituksessa on erimielisyyksiä ilmastotoimista ja -tavoitteista.

Trump Administration Moves to Destroy Satellite That Monitors Greenhouse Gases
https://gizmodo.com/trump-administration-moves-to-destroy-satellite-that-monitors-greenhouse-gases-2000639234
The Orbiting Carbon Observatories have been a game-changer for agriculture and climate science. Now, NASA is under pressure to terminate them.
The Trump Administration’s budget proposal for Fiscal Year 2026 would take an axe to NASA science. Two satellite missions on the chopping block have provided climate scientists, oil and gas companies, and farmers with critical atmospheric carbon data for years.
The Orbiting Carbon Observatories are a pair of instruments that map atmospheric carbon on a global scale. NASA launched the OCO-2 in 2014 and mounted the OCO-3 on the International Space Station in 2019. Trump’s budget proposal threatens both missions, but the standalone OCO-2 would be completely destroyed during its fiery descent through Earth’s atmosphere. Though the budget has yet to pass, NPR reports that NASA scientists working on the OCO missions are already making “Phase F” plans—essentially laying out options for termination.

Scientists Find Evidence That You’re a Hypocrite Who’s Causing More Than Your Share of Climate Change

When it comes to personal contributions to climate change, most Americans seem to have no clue how damaging some of their individual actions can be.
Folks who happily recycle and switch to more energy-efficient appliances, per a recent study published in the Proceedings of the National Academy of Sciences Nexus journal, likely have a far larger carbon footprint than they realize.
As paper co-author and Stanford environmental social scientist Madalina Vlasceanu told the AP, the survey participants tended to “over-assign impact to actually pretty low-impact actions such as recycling, and underestimate the actual carbon impact of behaviors much more carbon intensive, like flying or eating meat.”
“Recycling is an almost daily action, whereas flying is less frequent. It’s less discussed,” Zhao told the AP. “As a result, people give a higher psychological weight to recycling.”
Ultimately, it boils down to what is visible and what is not.
“You can see the bottle being recycled. That’s visible,” she continued. “Whereas carbon emissions, that’s invisible to the human eye. So that’s why we don’t associate emissions with flying.”
With flying and eating meat — and, by extension, owning a dog that eats meat-based food — among the top culprits adding to your individual carbon footprint, folks who fly a lot or have dogs may be unaware of just how much they’re polluting.
Still, there hasn’t been much public messaging about how pets can contribute to climate change — and as Vlasceanu put it in a statement about the study, “nobody understands” carbon emissions anyway.
“It’s so abstract,” she said, “you’ll forget it immediately.”

It’s Official: NASA Is Giving Up on Climate Change Science
https://futurism.com/the-byte/nasa-giving-up-climate-change-science?fbclid=IwQ0xDSwMSO_BjbGNrAxI74mV4dG4DYWVtAjExAAEeW8rBKaEYBQfsrmB6rX0gCHAKSFr793uFEjN4CojKztLbSY93k_ctkhOnyjM_aem_W8AmAzJEMtDUdVZ-oObKew
In a major blow to climate change science, NASA is officially not continuing its work studying global warming and will instead just stick to space exploration.
During a Fox Business news segment, acting NASA Administrator Sean Duffy (who also happens to be the Secretary of Transportation) dropped the bombshell during a live interview on Thursday.
“All the climate science and all of the other priorities that the last administration had at NASA we’re going to move aside, and all of the science that we do is going to be directed towards exploration, which is the mission of NASA,” he said. “That’s why we have NASA — is to explore, not to do all of these Earth sciences.”
The news is not so surprising given the fact that President Donald Trump has long been known to be a climate change denier.
His anti-science agenda has systematically undercut any climate research. Just last month, the Department of Energy issued an error-riddled report that denied the existence and impact of global warming.
Giving Up
For NASA, the writing was on the wall when Trump officials forbade the space agency from hosting important climate assessment information on its website.
Trump officials had also ordered two important satellites that collect climate information to be terminated, which critics say doesn’t make any sense and could even break the law.
Most of all, it shows that administration officials have little respect for the scientists and engineers at NASA.

Heating things up is one of the biggest sources of cost and emissions for many industrial processes we take for granted. Most of these factories are running around the clock so they don’t have to waste energy cooling off and heating things back up, so how can you match this 24/7 cycle to the intermittent energy provided by renewables? This MIT spin-off thinks one solution is thermal storage refractory bricks.
Electrified Thermal Solutions takes the relatively simple technology of refractory brick to the next level. For the uninitiated, refractory bricks are typically ceramics with a huge amount of porosity to give them a combination of high thermal tolerance and very good insulating properties. A number of materials processes use them to maximize the use of the available heat energy.

Liikenteen pahin päästölähde paljastui – Se ei olekaan pakokaasu
Suurin osa yksityisliikenteen hiukkaspäästöistä on peräisin jarruista. Pakokaasujen osuus hiukkaspäästöistä on pienempi kuin rengaspölyn
https://www.iltalehti.fi/autouutiset/a/ae630fd9-b715-425e-9476-b069d0ba8b77
Jarrujen päästöt muodostavat suurimman osan autoilijoiden muodostamista ei-pakokaasupohjaisista pienhiukkasista. Jarrupölystä 40 prosenttia päätyy ilmaan ja loput maahan.
Asia ilmenee Euroopan unionin rahoittaman saksalaisen EIT Urban Mobilityn tutkimuksesta, jossa selvitettiin ei-pakokaasupohjaisia päästöjä tieliikenteessä.
Rengaskuluma todettiin toiseksi suurimmaksi ei-pakokaasupohjaiseksi päästölähteeksi. Renkaiden kulumisesta tulevat päästöt päätyvät pääosin ympäristöön ja ainoastaan 1–5 prosenttia päätyy ilmaan. Rengaspöly sekoittuu katupölyyn ja voi päätyä vesistöihin sekä maaperään.
Rengaspölyn määrä on erityisesti kaupungeissa suurempi. Kaupunkiajossa tehdään useita kiihdytyksiä, jarrutuksia ja käännöksiä. Lämmin ympäristö aiheuttaa renkaiden kulumista vielä enemmän.
Painavat ajoneuvot, kuten sähköautot tuottavat enemmän rengasperäistä saastetta. Tutkimus arvelee rengassaasteen koituvan pitkällä aikavälillä ongelmalliseksi.
Sähköautojen energiaa talteen ottavan moottorijarrutuksen todettiin vähentävän sähköautojen jarrupäästöjä peräti 80 prosenttia.
Pakokaasut murto-osa yksityisliikenteen hiukkaspäästöistä
Tutkimus nostaa esimerkiksi hiukkaspäästöistä Lontoon suuralueen. Lontoon yksityisliikenteen hiukkaspäästöt ovat enimmäkseen peräisin jarrupölystä. Pakokaasujen osuus hiukkaspäästöistä on rengashiukkasiakin pienempi.
Mopojen ja moottoripyörien sekä raskaan- ja julkisen liikenteen osalta pakokaasut muodostivat suurimman osan hiukkaspäästöistä.
Study on non-exhaust emissions (NEE) in road transport
https://www.eiturbanmobility.eu/knowledge-hub/non-exhaust-emission-study/
Why this study matters
More than 96% of the European population was exposed to PM2.5 concentrations exceeding the World Health Organization’s annual air quality guideline limit in 2022 .Road transport is a primary source of particulate matter in urban areas.
As exhaust emissions decrease, non-exhaust emissions (NEEs) – particles from brake, tyre and road wear – are now a dominant source of urban particulate matter (PM).
