Very proud of this team effort "A regional integrated assessment of the impacts of #climatechange and of the potential #adaptation avenues for #Quebec’s #forests" is now published

A (very long) thread. Buckle up!…

@cflscf @NRCan

First, I would like to acknowledge the work of all my colleagues including Jesus, Annie Claude, Yves, @mariehbrice, @DominicCyr, Louis, Daniel, @GauthierSylvie9 , Pierre, @Guillemette_L , Mathieu, Maryse, Tadeusz, Martin-Hugues, @ethiffault , @Tremblay_Jun and Stephen
Quebec’s #forests goes from northern hardwood with sugar #maple, beech, hemlock in the south, to pure boreal black #spruce forests up north. Natural #disturbances, go from single-tree windthrow or mortality in the south, to large stand-replacing #fires in the north.

Our new @NatureClimate paper just out! State-of-the-art estimates of economic impacts of climate change show that benefits of #ClimateAction outweigh the mitigation costs by a factor of 1.5 to 3.9 ➡️strong economic validation of #ParisAgreement 🔗 1/7
We combined climate impacts of
🟠sea-level rise,
🟡river floods,
🟢labour productivity,
🔵energy supply/demand,
🟤forestry and
⚫️road transportation
and transform this in financial costs. But not: ❌biodiversity loss❌health❌tipping points 2/7
For a 3°C scenario (RCP6.0, roughly current trend/baseline), economic impacts are 10-12% of GDP, with high regional differences. Even higher if sea-level rise adaptation is not optimal. 3/7

The #biodiversity of the #Danube #Delta is not affected by dredging works on the Bystroye Canal, and the water flow on the river Danube did not report any significant changes compared to statistics published in recent years, says Environment Minister @BarnaTanczos. (1/4)
The statement came after the 1st measurements conducted by RO on the branch of Chilia&RO sections of the Danube. He said Ukrainian authorities must provide a written consent before the 3 RO ships can finalize depth measurements across the entire section of the Chilia branch (2/4)
Authorities from Romania&Ukraine have agreed to measure the depth of #Danube River canals after Kyiv started #dredging the Bystroye canal. The Ukrainian Infrastructure Ministry said that, once dredging works were completed, the depth of Bystroye grew from 3.9 to 6.5 meters. (3/4)

Agreed. The singular advantage of money as a near-universally acceptable, reliable medium of exchange is that it breaks the need to know and trust counterparts all along the chain of trade & production. 1/x
This not only expands -and hence enriches- the network of exchange (think Adam Smith or “I, Pencil”) but removes node-occupying middlemen and toll-exactors. Efficiency increases, but transparency and fairness, too. 2/x
Once we have #CBDC-s -coupled to #Agenda2030 #IoT tracking of ‘#carbon’, meat protein, ‘circular economy’, low food miles, etc, we will have subjected ourselves to an intrusive, permanent rationing where a tax collector, a camp guard, and a Levitican Inquisitor...

@euro writes (vital thread) to warn us that

The #Amazon has absolutely crucial functions for the Earth's #biodiversity #climate #hydrology #carbon but is now rapidly changing! We humans are doing so at a rate that far outpaces natural processes: A thread of our Review in @ScienceMagazine… (1/9)
The #Amazon still covers vast areas of tropical rainforest, producing huge amounts of biomass, and concentrates at least 10% of all known plants and vertebrates on Earth. But intact ecosystems are now rapidly being reduced....(2/9) Amazon rainforest as seen in southern Venezuela. Picture by
We show that the rate of #deforestation and #degradation is much more rapid than previously throught, especially in southern Amazon. Main drivers are land-use changes, water-use changes (e.g. damming), and #climate change. These now combined are making a dangerous cocktail.

#BiodiversityLoss 🧵 1/5 Map of Great Britain on left showing protected natural areas
Almost 1 million records of 1,238 invertebrate species were included🐝. @RobertSCCooke & colleagues found that protected areas were richer in species than unprotected areas of the country but both suffered similar rates of decline in native insects and spiders between 1990-2018. Graph on left shows Species richness in protected and unprot
The results suggest that while protected areas are helping to conserve valuable habitats and the species within them, they need more help to tackle wider threats posed by climate change, pollution and invasive species that are causing #biodiversity loss…

There have been a steady stream of articles that say: 1) the plant-based meat sector is flagging; therefore 2) plant-based meat is a failed endeavor. These stories miss two critical points, a thread, 1/n:
tl/dr: 1) the theory of change has not been tried; this is like abandoning solar in 1986 or electric vehicles in 2003; 2) there is not an option that has a higher likelihood of success. If we abandon alt proteins, we will not meet climate targets (w/all that entails) + more. 2/n
FIRST: The alt proteins theory of change is that when the products compete on taste & price, they should be able to take a huge chunk of the market. But they don’t yet compete on taste and price - the current state is not future state. 3/n

3 confessions from #ClimateActivists & #ClimateEconomists seeking to tackle the #ClimateCrisis

We were wrong

-2 promise apple pie & motherhood sans costs
-2 repeat solar PV cheapest form of power sans caveats
-2 dismiss any trade-off between climate & development

Back in the day those, including me, who worked on many different versions of the #greendeal all focused on the win-win scenarios ... #greenjobs #greengrowth #justtransition etc. and tho the context has changed completely this win-win farming remains even in the year 2023
Had we mobilised on a war-footing back then, invested at scale, imposed #carbontaxes, innovated like mad & massively increased financial & technological support 4 developing economies to shun coal & adopt #renewables, the #greendeal may have worked, albeit not without real costs

Ok time to talk about getting those #renewables BUILT. 💪

Slow planning and permitting is stopping us from getting on track for net-zero. My colleagues @ETC_energy have set out what the problems are, and how we can try to address them. A 🧵
1. What's the size of the problem? Both solar and wind need to grow much faster to get on-track for net-zero by 2050. Current projections would lead to a power system that emits 2.2 GtCO2 more each year by 2030!

Need to close that gap!
As an aside, the only country that's crushing VRE deployment? China, obviously - and also Spain (nice one!).

How can water sensitivity transform our cities into sustainable urban spaces? 🧵 Image
What is the challenge for water-sensitive #urban design on a #city scale?

Turning an area spread across 1250 square km, divided into 3 major valleys & a tank system into a water-sustainable space. Image
But increasing urbanisation in the last few decades has been diminishing the city’s #water bodies.

A new paper shows that mature trees and woodlands are crucial in locking away carbon. Cutting edge laser scanning suggests previous estimates of carbon storage in woodlands could be significantly underestimated. (1/4) #CarbonCapture #Forests
Forests with older, larger trees appear to be especially effective at storing carbon. Scientists warn that "The value you have in large mature trees is almost incalculable, and so you should avoid losing that at any cost." (2/4) #ClimateChange #Trees
Politicians support the 'One Trillion Trees' campaign and advocate large scale planting programmes. However, new planting initiatives are of limited use in comparison to protecting existing forests. Monoculture planting can negatively impact biodiversity. (3/4) #SustainableForest

Someone asked me yesterday if the discovery nuclear fusion will mean we won't need degrowth anymore.
On the contrary, I think it underlines why degrowth is so important.
These 4 graphs show why. ImageImageImageImage
The short of it is, even if we invent a source of unlimited free energy, we are already crossing the boundaries of countless life support systems other than the carbon cycle.
In 2015, we had already crossed 3 planetary boundaries, including biodiversity.
Free energy won't solve that, we'll still need to transform and radically reduce our global material and energy use and destruction of ecosystems. In fact, it might speed it up.

BREAKING. We are in a position to confirm that @EmmanuelMacron sent a letter to Ursula @vonderleyen saying that the creation of a new fund for #biodiversity was a “redline”. #COP15 - see thread 👇🏼
Over and over, in private conversations with delegates, from the Global South and the Global North (even including the EU), we hear that @Elysee was blocking compromises, and single-handedly preventing the #EuropeanUnion from building bridges with developing countries.
This morning, we published an ad in Le Figaro and Libération, because we thought that it was a shocking failure of leadership that @EmmanuelMacron would go watch football instead of being here. ImageImage

Biodiversity is one of our planet’s most precious resources.

In fact, without biodiversity life as we know it wouldn’t exist.

Here are 9⃣ more things you may not know about #biodiversity 👇🧵

1⃣ Mountains host most of the world’s species of amphibians, birds & mammals.

Plants, animals, insects, microbes & their environment...

Biodiversity is vital to global food production & essential for human well-being.

2⃣ Most crops depend, at least in part, on pollination.

Our world is made of an invisible web, & loss of species weakens this web as well as whole ecosystems.

Take pollinators for example. Without them, most of our food wouldn't exist.
