Con gusto. New links to observe how the Arctic sea ice (#BOE) and Greenland ice sheet (#GIS) export fresh cold water to the Atlantic. How long until the AMOC tips and shuts down, accelerating warming and sea level rise?

Monsoons. Note what mental contortions the authors perform under the absurd @Peters_Glen @hausfath @MLiebreich crusade against #RCP85. Have we stopped this nonsense yet? egusphere.copernicus.org/preprints/2022…

@climate_ice, is GIS subglacial methane cycling accelerating? pulse.ghgsat.com/?lat=68.66&lng…
@Peters_Glen @hausfath @MLiebreich @climate_ice This really isn't hard. Please focus and do science that matters if you can. We need your support.
“These conclusions are not news; they were all included in a paper that we and other colleagues at the NASA Goddard Institute for Space Studies wrote in 1989.” etc., Hansen & Sato

We are fast running out of time. What you do now matters more than at any other point in history.
It has been clear for years that ice melt is faster than the worst-case scenarios considered by the IPCC (RCP8.5). This is important: if the IPCC underestimates how early and severely climate impacts will hit us, then states and markets globally systematically underestimate risk.

1. The structural parallels of SARS-CoV-2 and HIV-1 were known already 20 years ago, from SARS-CoV-1. Yet COVID-19 policy and even most scientists ignore these parallels, failing to learn key lessons. Fundamentally, genetic recombination drives both pandemics—two typical articles

2. Don't worry about the specific article—there are hundreds more, and more relevant ones. The lesson here is we face syndemics, overlapping epidemics that cluster with inequity, not just distinct pandemics. All reinforce each other

3. Background. There are literally thousands such articles; no one integrates them. That's why as political scientist, for years already, I've been arguing that only institutionalization can help with such complexity. We need a @UNAIDS for SARS-CoV, sorry

1. Growing bamboo is our best chance to avert climate breakdown: the plants build soil, help biodiversity, avoid GHG emissions, provide food & construction material, sequester carbon 30 times (!) faster than mixed temperate forest. Yet stunningly, no one coordinates this work yet 40 year old moso bamboo in southwestern France grown from seed. Photo Lihua Jiang, www.yunnan-bamboo.com
2. After 40 years of climate science - first AGGG, now IPCC -, everyone feels they know climate. Yet experts only really know their own field. Generalists and practitioners can implement solutions but need experts to develop them. Bamboo as climate solution is entirely unexplored

3. Last time atmospheric carbon content was as high as today, 16 million years ago, Earth was >3°C warmer than today, the Arctic was ice free, and Iceland had a subtropical climate. People think they know what climate change means, but most really don't. mdpi.com/2673-4834/5/2/…

We’ve shared this for years, it was known or suspected even before the pandemic from SARS-CoV-1. Friends of we’re going to learn at this rate, ignoring prepandemic science, populations worldwide will get into serious trouble
Background. Thanks for outstanding science communications @vipintukur
I'd like to delete my account, but then a sizable fraction of the early Covid twitter scicomm documentation - to show what was known when - would be gone. As far as I know, no one else with even a moderately sized account (>10k followers) shares the same readily available science

“Bamboo is our best chance to slow climate breakdown. It can replace drivers of GHG emissions and biodiversity loss (food, construction, concrete, plastic), build soil & allow regrowing rainforest." - Let's test it. Grow bamboo as blueprint for a future ecological civilization 🧵

2. Giant bamboo dwarfs trees. As grass, it grows 30 times (!) faster and can be harvested every year. Timber takes decades; too slow. Stunningly, no one in the west described the unique climate mitigation potential of bamboo yet. - Note the rhizome system:

3. Climate relevant will be the use in millions of ha of plantations, just like other economically important crops. After two months on this, some significant progress: air pot kindly donated 1 m of their professional U system, so I can test it for bamboo.

SARS-CoV-2 reminder: The more immune compromised the population, the less symptoms, the ‘milder’ it appears, the more severe it really is (=Long Covid, long term damage). That’s what even most scientists seem not to get
Thanks for vivid discussion everyone. It really is a fundamentally important point. Since I deleted most references for lack of structure (and frankly, just being fed up repeating the same points for 3 to 4 years), I'll look for new references that must have been published by now

1. "Bamboo is our best chance to slow climate breakdown: it sustains societies, can protect soil and store carbon for 100 years in food, construction, bio-concrete and plastic." - Let’s test this. As our very German neighbors renew their English Gardens, we start growing bamboo👇

2. Three months ago I started on bamboo: no one else in Europe seemed to have systematically analyzed or even considered its global climate mitigation potential when used as agricultural crop rather than natural forests, which do little climate mitigation.
3. A bamboo focus isn't for the coming years. We are at least a decade early. However, since getting started will take decades, now is a good time. In 10 years, atmospheric CO2 will exceed 450 ppm. That's enough to fundamentally transform the Earth system.
