Niklas HöhneThe Green Deal improved EU‘s climate performance by more than a degree, shows our Climate Action Tracker. Now the EU needs to keep up the momentum, go the extra step and not roll back.
Voters have a clear choice: Ambitious climate policy or even more droughts and floods.
StreetDogg@niklashoehne ~3°C as per plan vs. 4°C+ without the plan doesn't exactly sound very ambitious to me.
It's a choice to completely wreck our current way of life vs. just committing collective suicide right away.

@StreetDogg @niklashoehne the idea is that a concerted effort to get to +3C will open possibilities of getting down to +2C or even +1.5C.
@tob @niklashoehne My dude, the 1,5° ship has already sailed and we're currently happily waving the 2° ship goodbye, because *maybe* we gonna catch the 3° ship if we start trying anytime soon.
@StreetDogg @niklashoehne not your dude. Your nihilism doesn't make you a realist. At best, your rhetoric makes you irrelevant. At worst, it makes you part of the problem.
@tob @niklashoehne It's not nihilistic to demand a plan that keeps the planet habitable.
It's delusional to make plans that lead to purgatory and expect support for it, because at least it's not full hell. Especially if no plans before have ever been even remotely fulfilled.
Most people, polititians and voters alike, appear to still be in complete denial about the situation and the result of that is obvious and devastating. And I'm not happy about that...
Schreibmax@niklashoehne Good to know, thanks!
Seeing as side effects of the deal so far include better price stability, less dependence from imports, and better living standards, let’s increase our efforts and hopefully exceed the EU goals for 2030 and 2035!

Bill Tschumy@niklashoehne @ScienceDesk I would be a lot happier if that graph said “implemented policies” rather than “planned policies”. The IPCC has been making plans for 30 years and it has done squat all.

Richard Michael Blaber@niklashoehne There is no 1.5 C pathway - not for any of us, not in Europe, not anywhere on the planet. The current level of CO2 is 426.28 ppm (20/05/2024, https://www.co2.earth/), which is higher than at any time since the Mid-Piacenzian Warm Period, when there was 3 C of global warming. We would have that level of global warming right now, were it not for the cooling aerosols present in our atmosphere, which we need to remove, & are removing, because of their adverse health effects.

Atmospheric CO2 during the Mid-Piacenzian Warm Period and the M2 glaciation - Scientific Reports
The Piacenzian stage of the Pliocene (2.6 to 3.6 Ma) is the most recent past interval of sustained global warmth with mean global temperatures markedly higher (by ~2–3 °C) than today. Quantifying CO2 levels during the mid-Piacenzian Warm Period (mPWP) provides a means, therefore, to deepen our understanding of Earth System behaviour in a warm climate state. Here we present a new high-resolution record of atmospheric CO2 using the δ11B-pH proxy from 3.35 to 3.15 million years ago (Ma) at a temporal resolution of 1 sample per 3–6 thousand years (kyrs). Our study interval covers both the coolest marine isotope stage of the mPWP, M2 (~3.3 Ma) and the transition into its warmest phase including interglacial KM5c (centered on ~3.205 Ma) which has a similar orbital configuration to present. We find that CO2 ranged from $${{\bf{394}}}_{{\boldsymbol{-}}{\bf{9}}}^{{\boldsymbol{+}}{\bf{34}}}$$ ppm to $${{\bf{330}}}_{{\boldsymbol{-}}{\bf{21}}}^{{\boldsymbol{+}}{\bf{14}}}$$ ppm: with CO2 during the KM5c interglacial being $${{\bf{391}}}_{{\boldsymbol{-}}{\bf{28}}}^{{\boldsymbol{+}}{\bf{30}}}$$ ppm (at 95% confidence). Our findings corroborate the idea that changes in atmospheric CO2 levels played a distinct role in climate variability during the mPWP. They also facilitate ongoing data-model comparisons and suggest that, at present rates of human emissions, there will be more CO2 in Earth’s atmosphere by 2025 than at any time in at least the last 3.3 million years.
