The Guardian on our new study, which shows that global heating is significantly gathering speed. Our efforts to overcome our fossil fuel addiction should do the same.

Design | Artek joutuu kasvattamaan omia koivuja – Syy: Suomalainen tehometsätalous Suomalainen metsänhoito ei tuota sellaista koivua, jota Artek tarvitsee Aalto-huonekaluihinsa. Siksi designyritys ostaa nyt omaa metsää.

Korkeaa jalostusastetta ja luontomyönteistä metsätaloutta.
Näistä on helppo tykätä.

🚨 Alert: Insects are vanishing at an alarming rate,up to 76% decline in flying insect biomass over 27 years in Germany alone!a1891c This "insect apocalypse" is driven by pesticides & habitat loss, threatening our ecosystems. We must act NOW to save them! #SaveInsects #NoPesticides

An infographic from Our World in Data titled "Global land use for food production" uses a series of stacked horizontal bar charts to visualize the distribution of Earth's surface and the disproportionate land requirements of livestock. The first bar shows Earth's surface is 71% ocean and 29% land (141 million km²); the land surface is then broken down into 76% habitable land, 10% glaciers, and 14% barren land. Of the habitable land, 45% (48 million km²) is used for agriculture, while 38% is forests and 13% is shrubland. The agricultural land bar reveals a major disparity: 80% (38 million km²) is dedicated to livestock (meat, dairy, and textiles) including grazing land and cropland for feed, while only 16% is used for crops for direct human consumption and 4% for non-food crops. Finally, two smaller bars at the bottom contrast this land use with nutritional output, showing that while livestock uses 80% of agricultural land, it only provides 17% of global calories and 38% of global protein, whereas plant-based foods provide 83% of calories and 62% of protein.

80% of agricultural land is used for livestock (and textiles), yet this huge land use provides only 17% of our calories and 38% of our protein.

16% of the land used for crops provides 83% of our calories and 62% of our protein. It's past time we rethink what we eat.

Biodiversity collapse threatens UK security, intelligence chiefs warn Ecosystem destruction will increase food shortages, disorder and mass migration, with effects already being felt

"Without significant increases in UK food system and supply chain resilience, it is unlikely the UK would be able to maintain food security if ecosystem collapse drives geopolitical competition for food" - says Joint Intelligence Cttee. www.theguardian.com/environment/...

Pelkkä suomalaisuus ei ole valtti.

"Syy on osittain elintarvikebisneksen luonteessa. Jos kysyy ranskalaiselta, sveitsiläiseltä, italialaiselta tai keneltä tahansa, mistä maailman parhaat elintarvikkeet tulevat, he sanovat oman kotimaansa. Kuten suomalaisetkin."

One of the biggest microplastic pollution sources isn’t straws or grocery bags – it’s your tires Every few years, the tires on your car wear thin and need to be replaced. But where does that lost tire material go? The answer, unfortunately, is often waterways, where the tiny microplastic particle...

I see there’s a post about microplastics going around with a photo of drinking straws, so here is my semi-regular reminder that the 3 biggest sources of microplastics are tires (45%), synthetic clothing particles (35%) and paint (~10%).

This week, Professor James Hansen and colleagues published projections that the global temperature record could reach +1.7°C by 2027.

Politiikka | Tutkijat lähtivät hankkeesta poliittisen sekaantumisen vuoksi – tieto vetäytymisestä haluttiin kätkeä Tutkijat irtisanoutuivat ministeriön tilaamasta luontoraportista. He kokivat, että poliittisen ohjauksen sotkemalla raportilla voi olla ikäviä seurauksia luonnolle ja tieteen uskottavuudelle.

Jos taitaa olla nyt kun.

Jos tämä vaivaa ja haluaa tehdä jotain, niin:
-Voi syödä enemmän viljaa ja kasviksia (välttää rehutyppihävikin)
-Voi ostaa luomua (viljelty ilman ammoniakkityppeä)
-Voi kysyä kansanedustajista, mitä ne tälle meinaa tehdä

If we play this out: What would 3 °C of warming mean in 25 years? What would the world look like? FB: We would all live in different climate zones. Open an old world atlas and you see a huge red patch for the Sahara. With 3 °C of warming, that zone would stretch into parts of Spain. Vegetation, rainfall weather patterns, all would look very different. And what would 3 °C mean for Germany? FB: In summer, meteorological records could reach up to 50 °C. Three degrees of global warming does not mean hot days will just be 3 or 4 degrees hotter. It could mean up to 10 degrees hotter. We would also face much

Warning from German scientists that current observations of emissions and ocean temperatures make 3C of #globalheating by mid-century plausible.

3C of heating makes our current global society unlivable, by the way. Parts of Spain become the Sahara, eg.

Over a pint in Oxford, we may have stumbled upon the holy grail of agriculture | George Monbiot I knew that a revolution in our understanding of soil could change the world. Then came a eureka moment – and the birth of the Earth Rover Program, says Guardian columnist George Monbiot

Tulosten mukaan ohra ja luonnonhoitonurmi ovat kasveja, joiden kohdalla heijastus lisää aurinkosähkön tuotantoa hieman pystyyn asennetuissa paneeleissa, mutta vaikutus vuoden kokonaistuotantoon on maltillinen. Tärkein aurinkosähkön tuotantoon vaikuttava tekijä on edelleen paneelirivien välitys.

Käyttämällä vain 10 prosenttia peltoalasta pystysuuntaisiin paneeleihin, viljelijä voi tuottaa noin kolmasosan siitä energiasta, jonka kokonainen pelto katettuna eteläsuuntaisilla paneeleilla tuottaisi. Väliin jäävällä alalla voidaan jatkaa viljelyä entiseen tapaan.

Climate change is the world's most pressing issue because it makes everything else worse. It enables dictators, it drives inflation, it makes survival harder for the poorest people in the world.

And the new data are clear: the rate of climate change is accelerating.

The US is the world's largest oil and gas producer. Yet, "China is now making more money from exporting green technology than America makes from exporting fossil fuels."
