Un estudio de los últimos 30 años encuentra una disminución significativa del almacenamiento de agua en el 53% de los casi 2,000 mayores cuerpos de agua (lagos artificiales y naturales) estudiados 🧵

Y principalmente NO por el consumo humano.
En los lagos naturales, las pérdidas tienen como causa:
44.4% Menor precipitación y escorrentía.
31.4% Mayores temperaturas (y consecuente mayores necesidades de las plantas).
14.4% Actividades humanas.

Aunque también hay lagos naturales que ganan reservas, de nuevo gracias a cambios en el clima: precipitación y temperatura.

Hey! You forgot about the #IPCC report!
Don't worry - I'm going to do another thread here, this time with highlights from the 'longer report', which is longer than the summary of the synthesis, but shorter than the as-yet unreleased full synthesis (which are all summaries)

The most vulnerable countries also tend to have the lowest emissions per person
It feels old hat now but it's still an important point.

El informe certifica que nuestro mundo ya está experimentando efectos catastróficos del cambio climático, como sequías prolongadas, lluvias torrenciales y otros fenómenos extremos. #CambioClimatico
Efectos con importantes consecuencias sociales: el informe reconoce que este calentamiento global ha provocado ya muertes, desplazamientos, y la pérdida de cosechas y de pesquerías y, con ello, ha agravado la hambruna en regiones como el cuerno de África. ipcc.ch/report/sixth-a…
Berlin konnte sich nicht zu ambitionierten Klimazielen durchringen. Das ist frustrierend und ein Verlust für alle, die einen intakten Planeten zum Leben brauchen – auch für die, die beim #Klimavolksentscheid mit Nein stimmten. Dass das so viele waren, ist erschreckend. ⬇️
Wie sehr die Regierungen weltweit beim Klimaschutz versagen, und wie unzureichend aktuelle Ziele sind, hat kürzlich erst wieder der #IPCC bestätigt. Momentan steuern wir auf 3,2 Grad Erhitzung zu. @klimaneustart
Dass diese Tatsache zwei Drittel der Wähler*innen nicht zur Wahlurne treibt, ist schon bemerkenswert. Dass 423.418 Berliner*innen sich aber die Mühe machten, wählen zu gehen und mit Nein zu stimmen, zeigt, wie riesig der Gegenwind für ambitionierten Klimaschutz war und ist.
Hace tiempo que quiero hace un hilo sobre el #decrecimiento, el cual vengo estudiando y escribiendo al respecto desde hace 1 década. A luz del último #reporte del #IPCC, se hace más que necesario. 🧵
El decrecimiento tiene sus raíces en diversas corrientes de pensamiento, como la economía ecológica, la crítica al desarrollo y la filosofía de la simplicidad voluntaria🧵
Aunque algunas de sus ideas pueden rastrearse hasta el siglo XVIII, fue en la década de 1960 y 1970 cuando cobró fuerza, gracias a eventos como la publicación del informe "Los límites del crecimiento" por el Club de Roma en 1972 y la crisis del petróleo de 1973.🧵
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 🔗 rdcu.be/c8jSK 1/7
We combined climate impacts of
🔴agriculture,
🟠sea-level rise,
🟡river floods,
🟢labour productivity,
🔵energy supply/demand,
🟣fishery,
🟤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

In recent #IPCC report, developing countries insisted a disclaimer be highlighted in a separate box. That models "do not make explicit assumptions about global equity, environmental justice or intra-regional income distribution." 🧵
For @carboncopyinfo carboncopy.info/ipccs-climate-…
For @carboncopyinfo carboncopy.info/ipccs-climate-…
So what does this disclaimer mean? What are the assumptions underlying modelled emission reduction pathways & why are they not driven by equity-based considerations like burden of energy transition on poorer countries?
Let's start with how models call for a rapid & drastic decline in only one fossil fuel which is primarily used in the developing world i.e. coal. A recent study by @FuelOnTheFire questioned the socio-political feasibility of such pathways & the leeway they provide for oil & gas
“… hatte Wissings Ministerium bereits einen eigenen, weitgehenden Vorschlag vorgelegt. In ihm ist gar nicht vorgesehen, dass Autos ab 2035 nur unter der Bedingung mit Verbrennungsmotor zugelassen werden, dass sie keine Treibhausgase mehr ausstoßen” spiegel.de/politik/eu-kom…
Jetzt haben @Wissing und @c_lindner endlich verraten, worum es ihnen in Wahrheit geht: Nicht um E-Fuels, nicht un “Technologieoffenheit”, sondern einfach darum, dass sich gar nichts ändert. Und das im Angesicht des neuen #IPCC-Berichts und des Versagens des @bmdv bei Sektorzielen
Hate to say I told you so. spiegel.de/wissenschaft/m…
We often talk in terms of future projections, but here's the thing: climate change is already driving major increases in food insecurity and malnutrition. A short #IPCC report🧵
"Increasing weather and climate extreme events have exposed millions of people to acute food insecurity (food insecurity with a severity that threatens lives, livelihoods or both)."
Food production is already constrained by changing weather conditions.
It's fossil profits or life.
Achieving a full phase out of fossil fuels as demanded by the #IPCC means an end to fossil profits.
Yet they are still on the rise. The oil and gas industry has delivered $2.8bn a day in unearned profit for the last 50 years. A total of $52tn.

Here some related comments by @JKSteinberger
9 years in the making, yesterday's #IPCC 6th assessment report synthesises a 6000-page (?) summary of climate and related sciences, and is arranged around 18 'headline statements'
I'm going to try and summarise it in 18 plain-language tweets 😬

1/ By burning stuff & emitting gasses we’ve DEFINITELY heated the world by 1.1C, but we haven’t stopped doing it. Wealthy countries and individuals have contributed much more to the problem, so we’re not equally to blame
2/ This has already had massive impacts on the weather, the oceans and the living world, everywhere on Earth. These changes have been catastrophic for people and nature, but those who have contributed least to the problem are the ones paying most of the costs
Something I find infuriating in certain corners of UK discourse is the idea that addressing climate is a threat to working classes. It’s not. It’s a massive opportunity to make things better *if we get it right*. The biggest threat to all of us is the status quo.
The earth is warming, devastating people and places around the world, driven by governments and fossil fuel shareholders who are making more money than ever before while people spiral into destitution because of soaring energy bills.
Workers have to fight tooth and nail for a basic liveable wage while shareholders rake it in and plough their money into oil and gas investments. Lowest living standards on record. Climate in breakdown. People and ecosystems disappearing.
