NEW: The latest climate pledges under the Paris Agreement have driven only a slight fall in predicted global temperature rise over the course of this century.

The UN Emissions Gap Report finds that implementing current policies would lead to up to 2.8°C of warming, down from 3.1°C. 🧵

🌊 Ocean warming threatens the viability of 60% of Antarctic ice shelves

If global temps stay <2 °C, nearly all 64 ice shelves survive by 2300. But above ~4.5 °C, ocean melt causes 38 shelves to collapse by 2300, risking up to 10 m sea level rise.

Ocean warming threatens the viability of 60% of Antarctic ice shelves - Nature

The viability of Antarctic ice shelves under low rates and high rates of global warming is modelled to estimate when it will become unfeasible for the ice shelves to maintain their present-day shape.

Terwijl de stembureaus nog open zijn, druppelen bij ons de eerste oproepen van bedrijfs- en lobbyorganisaties richting de nieuwe Tweede Kamer en nieuwe regering al binnen.

JA21 wil niets qua klimaatbeleid. Volstrekt desastreus op dat gebied. Houding richting EU onverenigbaar met D66 en GL/PvdA. Concreet zou JA21 het overgrote deel van haar verkiezingsprogramma overboord moeten zetten om dit mogelijk te maken. Ondenkbaar lijkt me.

Maar daarvoor moet de VVD genoeg verliezen om een koerswijziging mogelijk te maken. Een beetje wat Bontenbal heeft gedaan met het CDA.

Climate Action @climateaction.bsky.social · 6d

Maar het is ook precies de blunder die Yesilgoz heeft gemaakt door vd VVD een PVV-light te maken. Rutte (en bijv een Dijkhof) kon centrumrechts en rechts verenigen in 1 partij. En daar liggen in NL al decennia lang de meeste stemmen (helaas). Als de VVD dat inziet, dan kan alles snel veranderen...

Climate Action @climateaction.bsky.social · 6d

De ironie is dus dat je voor een stabiele regering absoluut geen VVD moet stemmen, gezien hun opstelling van uitsluiten en blokkades opleggen.

Climate Action @climateaction.bsky.social · 6d

Alles valt of staat hoe groot de romp GL/PvdA, D66, CDA wordt. Als die ± 70 zetels is of groter dan kan daar prima een minderheidskabinet gevormd mee worden met gedoogsteun enkele linkse/midden partijen (CU, SP, PvdD, Volt). Kleiner dan dat en VVD (zonder Yesilgoz) moet een draai maken...

Geeft aan dat stemmen obv advies kinderen geen goed idee is. Persoonlijk zou ik het mee laten wegen en aanleiding zien voor een mooie politieke discussie met je kinderen waarom je wel of niet van hun advies afwijkt. Een open, inhoudelijke politieke discussie is op lange termijn meer waard dan 1 stem

“Air pollution fell substantially as Paris restricted car traffic and made way for parks, people-streets and bike-lanes.”

Better for the climate, better for health, better for livability and quality of life.

Common sense.

Such a no-brainer, it’s remarkable that more cities HAVEN’T done the same.

Paris said au revoir to cars. Air pollution maps reveal a dramatic change.

The UN sees the world's planet-warming greenhouse emissions falling at far too slow a pace.

UN Sees World’s Emissions Falling 10% by 2035, Far Short of 60% Goal

The pace of emissions reductions is “still not nearly fast enough,” according to UNFCCC’s Stiel.

" Our findings suggest the potential for a similar response to climate change by woody aboveground biomass in moist tropical forests globally, which could culminate in a long-term switch from carbon sinks to carbon sources."

Climate Action @climateaction.bsky.social · 17d

And to counter a common climate-skeptic talking point:
"... with no evidence of the carbon fertilization (stimulation) of woody tree growth."

"All global modelled pathways that limit warming to 1.5°C (>50%) with no or limited overshoot, and those that limit warming to 2°C (>67%), involve rapid and deep and, in most cases, immediate greenhouse gas emissions reductions in all sectors this decade."

#Sufficiency

www.ipcc.ch/report/ar6/s...

Limiting warming to the Paris Agreement targets requires rapid, deep, and in most cases, immediate reductions in GHG emissions. Net-zero is achieved with emissions reductions, as shown in the graphic. Implemented policies overshoot the targets.

As expected
Plug-in hybrid electric vehicles (PHEVs) pump out 5 times more planet-heating pollution than official figures show.
Data shows PHEVs emit just 19% less CO2 than petrol and diesel cars
Under laboratory tests, they were assumed to be 75% less polluting

Analysis of 800,000 European cars found real-world pollution from plug-in hybrids nearly five times greater than lab tests

"The magnitude and duration of global temperature overshoot above 1.5°C has to be minimised. To achieve that, global anthropogenic greenhouse gas emissions must be halved by 2030 (compared to 2010 levels) and then reach net zero by 2050."
