Species extinction, more widespread disease, unliveable heat, ecosystem collapse, cities menaced by rising seas -- these and other devastating climate impacts are accelerating and bound to become painfully obvious before a child born today turns 30.

The choices societies make now will determine whether our species thrives or simply survives as the 21st century unfolds, the Intergovernmental Panel on Climate Change (IPCC) says in a draft report seen exclusively by AFP.

But dangerous thresholds are closer than once thought, and dire consequences stemming from decades of unbridled carbon pollution are unavoidable in the short term.

"The worst is yet to come, affecting our children's and grandchildren's lives much more than our own," the report says.

Explainer: How climate change is affecting wildfires around the world

Further south, in California, a research paper published in 2020 found that the number of autumn days with weather suitable for wildfires has doubled since the 1980s as a result of climate change.

The lengthening of fire seasons in California has had a knock-on effect on plant “phenology” – the timing of key events in plants’ life cycle, says Dr Frank Lake, a fire ecologist for the United States Forest Service. He tells Carbon Brief:

“We have seen due to climatic change, often hotter, drier conditions in California. We’ve seen longer fire seasons, which has also affected plant phenology, and we have extended periods of drought. That has definitely dried out the fuels [vegetation] and increased fire activity.”

SHEFIK: mno, tak hlavně Kalifornie je z velké části poušť / polopoušť a savana. Nikdy tam neměly vzniknout aglomerace typu Los Angeles, které prostě NEMÁ vodu pro ty miliony lidí - jestliže se voda musí přivádět stovky mil akvadukty, aby se spotřebovala v obrovských městech v poušti, tak pak samozřejmě chybí v krajině. Najděte si obrázky toho, jak vypadají kalifornské akvadukty - betonová koryta, vedoucí skutečně i stovky kilometrů - ta voda jen protéká (případně se vypařuje - viz. betonové koryto).

Lake Mead dokončené v roce 1935 mělo zásobovat okolní města. Vegas mělo v roce 1940 osm a půl tisíce obyvatel, dneska má tři čtvrtě milionu (celá aglomerace pak přes dva miliony).

Oblast SF zátoky má by woko nějakých deset milionů lidí - opět bere vodu ze Sierry, v místních Santa Cruz Mountains, které jsou hustě obydlené a kam nevede ta voda ze Sierry, jsou sousedské boje o vodu a studny - 37. rovnoběžka je úroveň Alžírska, to není podnebí, do kterého se dají naflákat miliony lidí. To prostě není udržitelné. Ani v té Kalifornii, natož pak v místech jako jsou Nevadské pouště.

New Report: Major disruption in food and agriculture in next decade — RethinkX

Combining solar power and microbes could produce 10 times more protein than crops such as soya beans, according to a new study.

The system would also have very little impact on the environment, the researchers said, in stark contrast to livestock farming which results in huge amounts of climate-heating gases as well as water pollution.

The concept uses electricity from solar panels and carbon dioxide from the air to create fuel for microbes, which are grown in bioreactor vats and then processed into dry protein powders. The process makes highly efficient use of land, water and fertiliser and could be deployed anywhere, not just in countries with strong sunshine or fertile soils, the scientists said.

Food security is a “critical issue” for humanity in coming decades, they said, with the global population growing, biofuels competing for land with crops, and about 800 million people already undernourished today. Furthermore, tackling the climate crisis will be near impossible without slashing emissions from animal and dairy food production.
