    And, despite all UK govt efforts for new nuclear and shale gas, it’s renewables that keep growing, providing 1/3 of UK electricity production in 2018, with over half of that from wind.

    NL emissions per kWh of electricity slowly coming down from their 2015 peak again, now some old coal-fired power plants were closed and renewables grow. Will accelerate from next year, when new offshore wind farms start to come online. Graph: !

    I don’t think that’s true. Denmark’s CO2 emissions in 2000 were roughly equal to those in 1990, but after that there has been a significant drop.

    Duk vond dat ie in principe toch gelijk had:

    Electricity from brown coal in Australia seems on its way out. Black coal still standing, but now also under pressure from lots of wind and solar capacity under construction. Via

    2018 was the 3rd warmest year on record in Helsinki, Finland: +1.4°C above the 1981-2010 average, behind 2015 and 2008, and on par with 2014: Above normal in all of the country, more so in the North. Link and maps via

    Belgium had its warmest year ever, tied with 2014. Orange line is 1981-2010 normal. Graph: ,

    After a sluggish regrowth so far this winter, Arctic sea ice ended the year at its 2nd lowest extent on record, only above 2017, and just below 2010 and 2016. Right = zooming in on December. ()

    The share of renewable electricity varies from week to week. The lowest weekly share was 26% in week 42 (Oct), and the highest was 53.5% in week 49 (Dec). So making it work at even higher shares is not just about day/night storage (batteries), but also about bridging those weeks

    That meant that renewables were able to replace the electricity from the nuclear power plants shut down since 2011 (Fukushima), and reduce electricity from gas (-35%) and hard coal (-25%) at the same time. Lignite (brown coal) use remained stable, due to its low marginal cost.

    In 15 years, the share of renewables in German electricity quintupled, from 8.5% in 2003 to 40.4% in 2018. Since just before its nuclear exit (2010), it gained 21%-points.

    Germany made it! Over 40% renewable electricity* in 2018, for the first time ever. After 38.2% in 2017, now 40.4%. Nuclear 13.3%, fossils 46.3% *) based on net power generation for the public grid. Thx Bruno for your data and charts!

    There they are! Our season tickets for the village ice skating rink. But after a December with March temperatures, no cold weather in sight yet.

    It looks like the 2018 annual average of atmospheric CO2, measured at Mauna Loa, was ~408.5 ppm; that’s +1.9 ppm above the 2017 average. Overall, still speeding in the wrong direction! No real dip this time, after the 2016 (El Niño) jump of +3.4 ppm (as opposed to post-1998).

    Looks like the December average of atmospheric CO2, measured at Mauna Loa, was ~409.1 ppm; that’s +2.3 ppm above last year’s value. Overall, still speeding in the wrong direction!

    Good morning! New Year's breakfast in full swing here;)

    No, sorry, the Vostok ice cores show that 400 ppm is unprecedented over their full 420,000 years. And it is clear that the steep warming of the past 50 years is ~100% manmade, and directly linked to the rapid increase in CO2.

    And to finish it off, it’s 10°C now, on New Year’s Eve.

    Averaged over a week, daily high temperatures in Australia were at least 4°C above normal in half of the country. Deviation from normal (“anomaly”) was highest in the *Southeast*, where maximum temperatures were 8 to 10°C above normal! (thx, , for the correction)
