Today, NASA and NOAA are announcing that 2020 was one for the record books, tying with 2016 for the warmest year since we've been tracking temperatures. NASA rates 2020 as the warmest ever, although by a margin that's not large enough to reach statistical significance; NOAA reverses the order , also without a significant difference between the two years. Whatever its precise rank, 2020 was the continuation of a worrying trend—the past seven years are all on the list of the seven warmest years on record, regardless of which source you turn to for your global temperatures.

Another reason for concern is that 2020 saw conditions the El Niño-Southern Oscillation (ENSO) in a state that, in the absence of human-driven climate change, would have produced relatively cool conditions.NASA's Gavin Schmidt said that, in the absence of the influence of the ENSO, 2020 would have been the warmest year on record. As shown in the chart below, strong El Niño years tend to be associated with warm records, while the cycle's opposing conditions, called La Niña, are typically associated with cooler conditions. 2016 was notable for having the strongest El Niño since the 1990s, an event that pushed temperatures far above the baseline where they'd spent most of the start of the century.

Since then, the El Niño-Southern Oscillation (ENSO) has been largely stuck in neutral , shifting back and forth between weak El Niños and La Niña tendencies. Temperatures dropped slightly, but not back to the conditions that were typical of the decade prior. 2020 saw temperatures match those of 2016's strong El Niño despite remaining stuck in neutral. "The previous record warm year, 2016, received a significant boost from a strong El Niño," Schmidt said in a statement. "The lack of a similar assist from El Niño this year is evidence that the background climate continues to warm due to greenhouse gases.”

    Another disaster is ready to catch the US unprepared: Drought / ArsTechnica · Friday, 17 April, 2020 - 17:27 · 1 minute

Dry years are ahead.

As the Colorado River slowly dwindles , groundwater resources are depleted , and wells are being dug ever deeper , the specter of drought looms in the US—particularly, but not exclusively, in the arid Southwest.

Preparing for gradual changes like these is not sexy or popular. But there is a huge amount of crucial work to be done to mitigate the worst possible outcomes of increasing drought, writes environmental politics researcher Megan Mullin in a paper in Science this week. Fragmented water systems across the country have a litany of critical vulnerabilities that will ensure that the worst effects of water scarcity will hit the most vulnerable people in society the hardest.

Crumbling into dust

The Southwest has experienced an abnormally dry period that started back in 2000—an emerging “megadrought” that is due partly to natural climate cycles and partly to anthropogenic climate change . Higher temperatures “increase moisture demand from the land surface,” writes climate risk researcher Toby Ault in a second Science paper on drought this week, “for the same reason that a sauna will dry out a towel faster than a steam room.” Climate driven changes in the patterns of snow and rainfall can also contribute to drought.

    Rebellyons-nous, occupation du pont Wilson à #Lyon

    Timothée Jaussoin · Monday, 16 September, 2019 - 07:46 edit · 1 minute

Le dimanche 15 septembre 2019, sous un soleil de plomb nous avons bloqué avec succès le pont Wilson en plein centre de #Lyon.

Cet évènement coup de poing, non-violent et festif nous a permis de dénoncer la gravité de la situation face aux chamboulements écologiques et climatiques que nous vivons présentement et à venir très prochainement.

Cet évènement a été relayé dans la presse par Rue89 et a fait l'ouverture du journal du soir France3 Rhône-Alpes.

De nombreuses actions de désobéissance civiles non-violentes sont à prévoir prochainement. Plus d'informations sur le site officiel de XR France et sur le site international.

    reducing cow flatulence

experimenting with an indigenous strain of miniature cattle that produce less milk than typical crossbred cows but are much better able to stand very hot weather. An unexpected surprise along the way, he said, was that these dwarf animals, which are about one-quarter the weight of crossbred cows, produce only one-seventh as much manure and one-tenth as much methane.

    putin puts down the heat

To his credit Putin has no qualms about yanking the chain of climate obsessed Western Politicians. During the recent G20 conference in Australia, when asked why there was a fleet of Russian Warships just outside Australian territorial waters, the Russian embassy replied the ships were there to research “climate change”.

    University student discovers root cause of global warming

    brashlybella · / global-warming-fixing · Thursday, 16 February, 2017 - 08:55

After over two years of study and observations, it was determined that several factors outside of the current climate change ‘consensus’ were actually the cause of the recorded increases in temperature. The earth’s gradually slowing rotation, therefore reduced centrifugal force, has allowed excess space dust and other debris to pile up rather than be thrown back into orbit. By accumulating more material, the diameter of the planet has increased, moving closer to the sun and therefore getting warmer.
