The climate outsider tackling Britain’s global warming mission – POLITICO

“This is a very different COP. This is not a negotiating COP,” said Christiana Figueres, the former head of the U.N. Framework Convention on Climate Change.

Rather than presiding over tortured debates on new international law, Sharma’s goal is to convince every country on earth to set a date for reaching net zero emissions, plus new climate targets for 2030. Under the 2015 Paris Agreement, they aren’t officially due to update their plans until 2025, but after scientists in 2018 produced evidence of the serious consequences of warming even 1.5 degrees — the world is already around 1.2 degrees hotter — many governments decided climate change was outpacing that time frame.

An update was planned for last November, but the COP26 was shifted to this year thanks to the pandemic.

How close are we to the temperature tipping point of the terrestrial biosphere? | Science Advances

"The temperature tipping point of the terrestrial biosphere lies not at the end of the century or beyond, but within the next 20 to 30 years (Figs. 2 and 3, A to D). Given the temperature limits of land carbon uptake presented here, without mitigating warming, we will cross the temperature threshold of the most productive biomes by midcentury, after which the land sink will degrade to only ~50% of current capacity if adaptation does not occur. While biomes will eventually shift spatially in response to warming, this process is unlikely to be a smooth migration, but rather a rapid disturbance-driven loss of present biomes (with additional emissions of carbon to the atmosphere), followed by a slower establishment of biomes more suited to the emerging climate. Furthermore, the establishment of new biomes is unlikely to be complete without human intervention and will be limited by edaphic factors, especially nutrient availability. This further suggests that we are rapidly entering temperature regimes where biosphere productivity will precipitously decline."

LINKOS: mně to neříkej, já jen doufám, že to ví ti správní v EU, protože zatím to tak nevypadá. počkáme si co vypadne z toho green zákona co chtějí schvalovat.

KEB: tak samozřejmě, že nemůžem nahradit uhlí dřevem a provozovat ty samé elektrárny dal. Limit našich ekosystémů nás omezuje, nejsme to ohromné kvantum energie takhle produkovat, mužem mít jen malé elektrárny co budou třeba vyrábět teplo a elektřinu z místních zdrojů, co nám ekosystém dovolí a třeba jen v zimě. Proto potřebujem jednak snížit náročnost našich domu, našeho průmyslu a toto snížené množství energie produkovat skrze oze

Farmer-managed natural regeneration as a land-restoration strategy: under what conditions does it work?

Scientists from World Agroforestry (ICRAF) and Wageningen University, Netherlands studying regeneration on farms in Burkina Faso and Ghana. They asked how regeneration is affected by human activities, land degradation and by nearby forests and trees.

LINKOS: vození soji a vození megatun dřeva na spálení je trochu dost rozdíl nemyslíš?

Ne tohle není ekologie ani omylem. A časem se ukáže, že je ekologický zločin moderní doby

The temperature dependence of global photosynthesis and respiration determine land carbon sink strength. While the land sink currently mitigates ~30% of anthropogenic carbon emissions, it is unclear whether this ecosystem service will persist and, more specifically, what hard temperature limits, if any, regulate carbon uptake. Here, we use the largest continuous carbon flux monitoring network to construct the first observationally derived temperature response curves for global land carbon uptake. We show that the mean temperature of the warmest quarter (3-month period) passed the thermal maximum for photosynthesis during the past decade. At higher temperatures, respiration rates continue to rise in contrast to sharply declining rates of photosynthesis. Under business-as-usual emissions, this divergence elicits a near halving of the land sink strength by as early as 2040.
