I suggest we all read this article very very very carefully…
Scientists estimate that the earth’s land ecosystems can hold enough additional vegetation to absorb between 40 and 100 gigatonnes of carbon from the atmosphere. Once this additional growth is achieved (a process which will take a number of decades), there is no capacity for additional carbon storage on land.
But our society is currently pouring CO₂ into the atmosphere at a rate of ten gigatonnes of carbon a year. Natural processes will struggle to keep pace with the deluge of greenhouse gases generated by the global economy. For example, I calculated that a single passenger on a round trip flight from Melbourne to New York City will emit roughly twice as much carbon (1600 kg C) as is contained in an oak tree half a meter in diameter (750 kg C).
Yet fundamental misunderstandings about carbon capture by land ecosystems can have devastating consequences, resulting in losses of biodiversity and an increase in CO₂ concentrations. This seems like a paradox – how can planting trees negatively impact the environment?
The answer lies in the subtle complexities of carbon capture in natural ecosystems. To avoid environmental damage, we must refrain from establishing forests where they naturally don’t belong, avoid “perverse incentives” to cut down existing forest in order to plant new trees, and consider how seedlings planted today might fare over the next several decades. #Climate#ClimateCrisis#CO2#Deforestation
So, I think we can all agree that the #IMF are not #green radicals... but its head Kristalina Georgieva has gone on record saying that climate-damaging carbon emissions needed to fall between 25% & 50% by 2030 but pledges so far would only lead to a "meagre" 11% cut;
She goes on: 'So that is to my mind the number one priority for this COP, is to recognise that business as usual has to be dropped'!
People of a certain age may recall the excellent demo that came out in 1999 for this game. I never got the full game at the time but now that I'm older with disposable income, I think I will finally give this a go. I've got some Pigs to mount!!...
Carbon dioxide removal (sucking CO2 out of the atmosphere to store somewhere) is now a huge topic of discussion in tech/carbon circles but the public hears almost nothing. We need to fix that - the timescales, costs, scaling and downsides all need to be debated publicly, and not just with a commercial slant. We (me, Rob Bellamy & Juerg Matter) were doing our bit at the Cheltenham Science Festival today, during a discussion brilliantly titled “Catch C if you Can”. #Carbon#CO2#climate#CDR
"A reconstruction of 66 million years of climate history indicates global temperature may be even more sensitive to carbon dioxide levels than current models estimate"
Flying may be bad for the environment, but taking the train in Europe is bad for your bank account, a new study has found.
Rail travel within the Continent remains 71% more expensive than flying, according to research by Greenpeace.
The report compared the prices of flights and trains on 112 European travel routes and found that taking the train was cheaper than a flight in only 23 cases.
Soil is a significant carbon reservoir, storing more carbon than all plants, animals and the atmosphere combined, making it crucial for addressing the climate crisis.
Microbes, such as bacteria and fungi, are the primary drivers of carbon storage in soil, surpassing other soil processes by a factor of four, according to a new study in Nature.
OH SNAPS! The #EU just passed its Green Claims Directive banning #greenwashing - including carbon off-setting "carbon neutral" claims COUGH APPLE WATCH COUGH
For my industry, this will force more traceability to substantiate green claims. AKA a GOOD thing!
... including a framework to evaluate models from several sustainability-related angles, including #EnergyEfficiency, #carbon intensity, #transparency, and #social implications
How do you approach questions of sustainability & #AIethics in your #GeoAI work?

For Example: The earth’s biggest pile of cash (the asset manager Blackrock, with $8.59 trillion dollars under management) named to its board of directors the CEO of the world’s largest oil company, Saudi Aramco, which has produced more #carbon#emissions than any firm on earth.
Apparently a lot of countries have been fudging their carbon numbers. Even with the fudged numbers, we weren't on track for the Paris Agreement... but when measured from satellites, emissions are actually still increasing. https://www.youtube.com/watch?v=3NPDq2ubKoo
Looking like governments aren't going to solve this in time, especially if they won't even use the real numbers. Maybe it's finally time for all of us to watch that new movie, "How to Blow up a Pipeline"? I hear it's actually pretty good.
"My experience of going to the #HouseOfCommons... is that the threshold of understanding of even the most basic stuff about agriculture, and soil and #carbon sequestration, just is not there. There is not the intellectual capacity or expertise in... parliament... to make informed critical decisions" – Maddy Harland, editor of Permaculture, interviewed by @Eceni
...since starting @ClimateMigration yesterday, the vast majority of Followers are from outside the US. Understand this is not a fun subject, but the disparity in attention to this topic is pretty striking.
