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.

For The First Time In Centuries, The World’s Population Will Decline In A Few Decades
https://www.iflscience.com/health-and-medicine/for-the-first-time-in-centuries-the-worlds-population-will-decline-in-next-few-decades/
For the first time in modern history, the global population is projected to decline within the next century, bringing with it a “revolution in the story of our human civilization” and profound shifts in the way people live their lives.
The world’s population currently stands at around 7.8 billion people. That number is forecasted to grow over the next few decades and peak in 2064 at around 9.7 billion people, before falling to 8.8 billion by 2100, according to a new study published in The Lancet.
“The last time that global population declined was in the mid 14th century, due to the Black Plague. If our forecast is correct, it will be the first time population decline is driven by fertility decline, as opposed to events such as a pandemic or famine,”

Dangerous Global Warming Threshold Will Be Crossed By 2042, Says New Research
https://www.iflscience.com/environment/dangerous-global-warming-threshold-will-be-crossed-by-2042-says-new-research/
An increase of 1.5 °C (2.7 °F) above pre-industrial average temperatures is seen as a dangerous threshold for the climate of our planet. The official Intergovernmental Panel on Climate Change (IPCC) estimated that it could happen by 2052. A new study has put forward a stricter range; the threshold will be crossed between 2027 and 2042.
As reported in Climate Dynamics, researchers have developed a Scaling Climate Response Function (SCRF) to extrapolate changes to temperatures up to the year 2100. The new method differs from the General Circulation Models (GCMs) used by the IPCC, which try to simulate the complexity of the climate of the entire planet.
“Our new approach to projecting the Earth’s temperature is based on historical climate data, rather than the theoretical relationships that are imperfectly captured by the GCMs. Our approach allows climate sensitivity and its uncertainty to be estimated from direct observations with few assumptions,”
The method cuts prediction uncertainties in half, and at the same time confirms that the “very likely warming ranges” for the next 80 years were consistent with those expected by the GCMs.
“Now that governments have finally decided to act on climate change, we must avoid situations where leaders can claim that even the weakest policies can avert dangerous consequences,” added co-author Shaun Lovejoy, a physics professor at McGill University. “With our new climate model and its next generation improvements, there’s less wiggle room.”
The average global temperature in 2019 was 1.1 °C (2 °F) above the pre-industrial level, and throughout 2020 monitoring agencies have registered months among the hottest on record. The effects of the climate crisis are not a distant worry. They are already here.

Tuoreen analyysin mukaan ruotsalaisen energiayhtiön Vattenfallin ydinvoima on tällä hetkellä jokseenkin puhtainta energiaa maailmassa. Sen elinkaaren aikainen hiilijalanjälki on vain 2,5 grammaa hiilidioksidia verkkoon tuotettua kilowattituntia kohti. Luku on merkittävä, sillä Vattenfallin ympäristöselosteen taustalla on ISO 14205 -sertifioitu elinkaarianalyysi.
Toiseksi puhtainta energiaa Ruotsissa on vesivoima. Sen päästöt 9 g / kWh. Kolmantena on tuulivoima 13 gramman kWh-päästöillä ja neljäntenä aurinkovoima 27 grammallaan.
Fossiilisiin energiamuotoihin yllä mainituilla on todella suuri ero. Hiilen polton päästöt ovat noin 800 grammaa / kWh ja kaasun puolestaan 490 grammaa.
Ydinvoiman päästöt muodostuvat muun muassa uraanimalmin kaivamisesta, rikastamisesta ja polttoaineeksi valmistamisesta, ydinvoimalan rakentamisesta, operoinnista ja purkamisesta sekä ydinjätteestä huolehtimisesta.
Vattenfallin ydinvoimaloissa suurimmat päästöt tulevat uraanin kaivamisesta ja rikastamisesta (noin 0,6 grammaa / kWh kummastakin) sekä ydinvoimalan rakentamisesta ja purkamisesta (noin 0,4 grammaa / kWh).
Ydinfysiikasta väitellyt kuntapoliitikko Petrus Pennanen puolestaan huomauttaa, että laadukas ydinvoima on vielä ympäristöystävällisempää kuin luultiin.

Carbon Dioxide Concentrations Will Reach A “Grim Milestone” In 2021
https://www.iflscience.com/environment/carbon-dioxide-concentrations-will-reach-a-grim-milestone-in-2021/
Our planet is set to reach a “grim milestone” this year: 2021 will see carbon dioxide (CO2) in the atmosphere reach levels 50 percent higher than those before the Industrial Revolution.
The new forecast by the UK Met Office says that the concentrations of CO2 will be around 2.29 parts per million (ppm) higher in 2021 than in 2020 at the Mauna Loa Observatory in Hawaii. This means atmospheric concentrations will exceed 417 ppm from April to June and be more than 50 percent higher than the level of 278 ppm seen in the late 18th century before the Industrial Revolution.
The last time global carbon dioxide levels were consistently above 400 ppm was around 4 million years ago, a period when the world was about 3°C (5.4°F) hotter and sea levels were much higher than today.

Carrot cement: How root vegetables and ash could make concrete more sustainable
https://horizon-magazine.eu/article/carrot-cement-how-root-vegetables-and-ash-could-make-concrete-more-sustainable.html
Concrete has become our building material of choice for countless structures such as bridges, towers and dams. But it also has a huge environmental footprint mostly due to carbon dioxide emissions from the production of cement – one of its main constituents. Researchers are now experimenting with root vegetables and recycled plastic in concrete to see whether this can make it stronger – and more sustainable – and even power streetlights or air pollution sensors.
After water, concrete is the most widely-used substance in the world. Producing cement, a key component of concrete, is responsible for about 8% of global carbon dioxide (CO2) emissions. It involves burning a lot of minerals, shells, shale and other components in kilns heated to about 1,400°C, where fossil fuels are typically used as an energy source, thus producing CO2 emissions.

In January 2020, Microsoft launched a company-wide focus on sustainability by announcing an ambitious goal and a detailed plan to become carbon negative by 2030, and by 2050 to remove from the environment more carbon than they have emitted since they were founded.
“When it comes to overall energy consumption”, Mr. Willis explained, “China is first, second is the U.S., and the third is datacenters.” He added that energy demand is expected to continue growing, and thus there is a growing need to address the associated carbon emissions.
Mr. Willis said that datacenters are the primary source of Microsoft’s emissions, but they have pledged to power their datacenter operations with 100% renewable energy by 2025. To address historical emissions, they launched a $1 billion Climate Innovation Fund that invests in global carbon reduction, capture and removal technologies.
Microsoft is involved in numerous partnerships with energy companies and governments to achieve its objectives.

Bill Gates-Backed Climate Solution Gains Traction, But Concerns Linger

Microsoft’s MSFT billionaire founder Bill Gates is financially backing the development of sun-dimming technology that would potentially reflect sunlight out of Earth’s atmosphere, triggering a global cooling effect. The Stratospheric Controlled Perturbation Experiment (SCoPEx), launched by Harvard University scientists, aims to examine this solution by spraying non-toxic calcium carbonate (CaCO3) dust into the atmosphere — a sun-reflecting aerosol that may offset the effects of global warming.
Widespread research into the efficacy of solar geoengineering has been stalled for years due to controversy. Opponents believe such science comes with unpredictable risks, including extreme shifts in weather patterns not dissimilar to warming trends we are already witnessing. Environmentalists similarly fear that a dramatic shift in mitigation strategy will be treated as a green light to continue emitting greenhouse gases with little to no changes in current consumption and production patterns.

It’s official. 2020 was one of the warmest years on record, either edging out or coming in just behind 2016 for the warmest year in recorded history according to data from U.S. government agencies (The National Aeronautics and Space Administration had the year just tied with 2016, while the National Oceanic and Atmospheric Administration put the figure just behind 2016’s totals).
No matter the ranking, the big picture for the climate isn’t pretty, according to scientists from NASA’s Goddard Institute for Space Studies (GISS) in New York and the Washington, DC-based NOAA.
“The last seven years have been the warmest seven years on record, typifying the ongoing and dramatic warming trend,”

The carbon cost of home delivery and how to avoid it
https://horizon-magazine.eu/article/carbon-cost-home-delivery-and-how-avoid-it.html
Delivering online shopping to people’s homes is a huge source of greenhouse gas emissions, particularly when deliveries fail and the journey needs to be repeated. Researchers are now re-thinking home deliveries to see if there is a better way of doing things, with ideas including robot couriers, jointly owned parcel lockers and an ‘Uber’ for parcels.
The problem begins with people like you. Let’s say you need a new shirt for work. You find one online and order it for delivery the next day. Your shirt will have probably have travelled by ship along with thousands of tonnes of other goods and then been carried by truck with many other articles of clothing to a warehouse. At some point, though, your shirt will have to be packaged up and carried directly to you.
It’s this last section of the logistics, known as the ‘last mile’, that is so troublesome. Here the packages’ routes split like the branches of a tree and make their way to many individual front doors, usually carried by a vast fleet of vans.
Online shopping still accounts for a fraction of all retail spending; below 20% in many developed countries. But it’s rising fast. In 2009, 36% of people in the EU had bought something online in the past 12 months, but by 2019 that had risen to 63%.
And delivery vehicles create a lot of greenhouse gas. Georgia Ayfantopoulou at the Hellenic Institute of transport in Thessaloniki, Greece, says that between 20% and 30% of a city’s carbon dioxide emissions come from last-mile deliveries. ‘It’s a major source of pollution, so in the context of climate change we need to do something about this,’ she said.

Lightning In A Bottle Might Allow Farmers To Make Eco-Friendly Ammonia Fertilizer
https://www.iflscience.com/chemistry/lightning-in-a-bottle-might-allow-farmers-to-make-ecofriendly-ammonia-fertilizer/
Ammonia production is responsible for about one percent of greenhouse gas emissions, although this could be underestimated. That may not sound like much, but we worry a lot about the emissions of air travel, which isn’t that much larger. It’s unlikely that nearly 8 billion people can live in this world without ammonia-based fertilizers, however, so a better way has to be found. Australian scientists think they’re close.
Ammonia (NH3) production currently relies on the Haber-Bosch process – which won the Nobel Prize in 1918 – but is badly in need of replacing. The process uses immense amounts of energy and relies on hydrogen, usually produced from methane, some of which leaks. “Green ammonia” can be made using renewable energy and electrolysis of water, but is currently very expensive.

BlackRock’s Larry Fink Wants Companies To Eliminate Greenhouse Gas Emissions By 2050

In his highly influential annual letter to CEOs, BlackRock CEO Larry Fink laid out an ambitious plan to combat climate change by pushing companies to make explicit plans for how their businesses will survive as the global economy works towards eliminating greenhouse gas emissions by 2050.
In the letter, Fink called on companies to “disclose a plan for how their business model will be compatible with a net zero economy.”
The letter defines a “net zero economy” as one where global warming is below 2 degrees Celsius and greenhouse gas emissions have reached net zero by 2050.
He warned that companies without a clear plan to address this transition will “see their valuations suffer” as customers, shareholders, policymakers, and employees lose confidence in the business.
This year’s letter echoes themes from Fink’s 2020 letter, where he said that climate change would be “a defining factor in companies’ long-term prospects” and pledged to refocus BlackRock’s investments with sustainability in mind.

‘In many cases it is more sustainable to produce food somewhere else and import it than grow it locally,’ says bioeconomist Dr Tessa Avermaete
Q&A: Why shorter isn’t necessarily better when it comes to food supply chains
https://horizon-magazine.eu/article/qa-why-shorter-isn-t-necessarily-better-when-it-comes-food-supply-chains.html#utm_source=Facebook&utm_medium=share&utm_campaign=supply
Fears over supermarket shortages during the early stages of the Covid-19 pandemic led many people to buy their food from local producers, raising the prospect of a transformation in the way people get their food in the future. But while eating locally and shorter supply chains are often viewed as a more sustainable alternative to our global food system, the reality is much more complicated, explains Dr Tessa Avermaete, a bioeconomist at the Katholieke Universiteit Leuven in Belgium.
What I think the Covid-19 crisis has shown is that actually the food supply chains are very robust. No one in Europe really went hungry because of Covid-19. But some farmers in Europe have suffered, particularly if they are exporting. In the potato sector, those exporting to China, for example, had tonnes of potatoes left. It has shown that we need to think about what happens when food supply chains are disrupted.
What have been the solutions to that?
One thing that people have talked a lot about is shorter supply chains. Certainly, during the pandemic many more people have been finding they have a local farmer or supplier out there they can buy from. This can be good for the local economy and be a way of getting healthy food. But we have to be honest – it is only a tiny part of the overall market. And it is quite likely that people will go back to their normal retailer once the crisis is over. But what I like is that it has started to get people thinking more about where their food comes from. When you look at the food system it is actually quite complex
Is buying local always more sustainable than buying from big retailers?
It’s easy to think that doing things locally is the right solution because it might on the surface seem to have a lower (environmental) footprint and reduce the risk of disruption. But not everything can be grown everywhere. There are some regions that have the right kind of fertile land needed for arable crops while others are better suited as pasture for livestock. Some land is suitable for soy but can’t be used to grow apple trees on. It makes sense to use your land in the way it is best suited for, and this is what our global food supply chains have allowed us to do.
We did some calculations at our university that if we tried to produce the livestock we consume in Belgium completely locally, then we would need double the land we have today just to produce fodder for the animals. In many cases it is more sustainable to produce food somewhere else and import it than grow it locally. Growing something in a heated greenhouse at a local farm can require more energy than growing it somewhere with more suitable climate and importing it by boat. The same applies with water – if it is too dry where you live, it can take a lot of extra water from the environment to grow some crops.
Bad weather conditions and plant diseases, or political disruption and wars could also prevent food from being produced locally at certain times. Global trade has given us some resilience to these.
Do local food networks have any advantages?
During the TRANSMANGO project (to assess the vulnerability and resilience of Europe’s food systems) we looked at how certain alternative food networks contribute to food security. These are things like small organic farms, farmers markets, local deliveries and community supported agriculture. They have a really important social factor because they can bring together communities. But in terms of overall food availability their contribution is limited. And we also saw that many of these alternative food networks are only accessible to people in middle and high socioeconomic classes. They don’t reach out to people in the lower classes.
Tomi Engdahl says:
To confront climate change, we need to understand the environmental footprint of global supply chains
https://horizon-magazine.eu/article/confront-climate-change-we-need-understand-environmental-footprint-global-supply-chains.html#utm_source=facebook&utm_medium=video&utm_campaign=supplychain
In 2020, the Covid-19 pandemic upended international trade. Countries shut their borders, breaking the webs of supply chains that crisscross the globe. These systems of people, organisations and companies work to supply consumers with products, such as mobile phones, or services, like transportation. While some supply chains have since returned to a semblance of normality, understanding their extent – and how they interact – may be vital if humanity wants to confront its other great challenge: climate change.
The European Union’s Green Deal places environmental sustainability at the heart of future economic development and targets a climate-neutral economy by 2050. But in a world of globalised supply chains, the bloc must be careful not to outsource its environmental impact to other nations, say experts.
