    Years it took us to drive up CO2 by 10 ppm: 320 → 330: 12 330 → 340: 8 340 → 350: 6 350 → 360: 7 360 → 370: 6 370 → 380: 5 380 → 390: 5 390 → 400: 5 400 → 410: 4 That’s making the climate crisis worse faster.

  2. SF6 = that powerful greenhouse gas used in electrical switchgear, and escaping in minute quantities, which the BBC helped hype as if it were a 'dirty secret of wind energy'. Avoiding its use would be great.

    In 2019 as a whole, Denmark got a record 47% of all its electricity from wind power: 29% from onshore wind farms, 18% from offshore. It’s the European champion, ahead of Ireland.

  5. The end of oil and gas in the Dutch part of the North Sea is drawing near: zero successful exploration wells in 2019; first time in decades. The transition from fossil fuels (decommissioning) to offshore wind (~180 GW before 2050) will be a massive one.

  6. By this time, Germany must have reached 50 GW of solar PV; it had 49.8 GW end of 2019. Adding 4 GW in a year used to be a lot, but now the Netherlands is catching up (relative to size and population), adding 2.4 GW in 2019.

    "The fossil fuel industry directly donated more than $85.7 million to Australian political parties in the 2018-19 financial year" 💰🔥💰🔥

    In Denmark, wind produced 113% of national electricity demand yesterday! And the time graph shows that during the night, wind farms even had to be "curtailed" (throttled down). Apparently not enough demand from or interconnection capacity with neighboring countries.

    Barcelona's climate emergency plan is 860M euros if scaled to NYC, or $946M. This is not exceptional, as NYC is spending $1.5B on the East Side Coastal Resiliency Project alone, which will raise the East River Park eight feet.

    Let's hope these guys stay at home if and when Mr Trump loses this year's elections.

    And, to apply it to your own city: the budget for Barcelona's climate emergency action plan is around €100 per inhabitant.

    Make sure the measures have multiple benefits, e.g. clean air. And communicate clearly on what happens if we don't act now. In the case of Barcelona: more intense heatwaves, more drought and extreme rainfall, more wildfires and... smaller beaches.

    This way, declaring a climate emergency makes sense. Show that you mean it by immediately announcing a coherent set of emission reduction measures, with a significant impact. And the budget to implement those.

    Barcelona City Council has declared the Climate Emergency, with an action plan and a budget of €563 million to implement 100 different measures. The goal is to cut annual greenhouse-gas emissions by 2 million tonnes. via

    Windy week coming to a close in Germany. On average, wind produced half of all electricity on the public grid! Together with the remaining nuclear, other renewables, and gas, it left just 16% for coal.

    Again a wind turbine that breaks down. Looks like this one was only around 12 years old. This has to be prevented: it’s dangerous and damaging for further development of wind energy. Better inspections needed, I’d say.

    Yesterday, on 1 February, the temperature exceeded 27⁰C in Valencia, Spain! Rare in February, and never happened this early.

    Someone I follow just shared this photo of a sign he saw attached to a front door in a block in Norwich. Brexit has encouraged and emboldened these people. It will get worse. Do whatever you can to support immigrants who face this shit. We all need to stand strong against it.
