"The Earth is the only world known so far to harbor life. There is nowhere else, at least in the near future, to which our species could migrate. Like it or not, Earth is where we make our stand."

17.05.2023: PROJECTION WARNINGS FOR 1.5°C LIMIT BREACH
Pacific Ocean conditions are now transitioning to an El Nino state – which will impart a further warming upon the planet in the coming year, in addition to the background carbon-driven warming.
The prospects for remaining below the 1.5°C U.N. warming limit are low. What does this mean for our fight to avoid serious planetary changes? Read our take here.
14.02.2023: SECOND STRATOSPHERIC WARMING. POSSIBLE MAJOR EVENT.
A second stratospheric warming event began over the North pole, 14th February. Forecast models indicate upper-air wind directions may reverse within 36 hours — which would officially mark a ‘major’ stratospheric warming.
If upper-air wind reversals persist, predictability for surface conditions over UK & N. Europe may be possible.
For comparison: In 2018, during the infamous ‘Beast from the East’ episode, upper-air wind reversals persisted for about 10 days before eventual emergence of cold surface weather about 3 weeks later.
Updates as and when we can.

5.02.2023: SUDDEN STRATOSPHERIC WARMING WEAKENS
The sudden-stratospheric warming event detected 25.1.2023 appears to be weakening, making a ‘major’ classification – and any influence on surface conditions – unlikely.
Major SSWs have an approximately 30% chance of leading to severe cold conditions over the European sector, the most pronounced recent example being in March 2018.

4.02.2023: SUDDEN STRATOSPHERIC WARMING DETECTION
The first sudden-stratospheric warming of northern-hemisphere winter 2022/2023 has been detected by JMA, originating 25.1.2023.
Current status is a ‘minor event’ — if elevated to ‘major’, predictability for surface conditions over the European sector may be possible for the next 3-to-4 weeks.
3.02.2023: ECWMF-SEASV SIMULATION OF SW-USA COLD ANOMALY
ECMWF-SEASV, one of six systems in our ESDV3 service, simulated southern, cold incursions which dominated south-western USA this week.
The magnitude of the cold anomaly appears mild in the forecast since the forecast is for the month as a whole – the cold snap being ironed out by other parts of the month which were normal.
Long-range forecasts of this type predict average conditions for the month as a whole and are increasing in their predictive skill. They are not, however, designed to indicate when in the month particular events will occur.

31.12.2022: EUROPEAN WARM ANOMALIES CHARACTERISE DECEMBER
North American / European sector, latest run ESD global monitoring code, 22nd December – 31st December 2022.
—————————
Expansive European heat conditions, up to 5°C warmer than normal; multiple cities report new maximum temperature records.
Colder-than-normal conditions evident for this time window, central North America, as a result of prevailing air flow [ red marker annotations ], counter-balanced by warm anomalies over Canadian Archipelago.
Context: As with summer heat events, warm anomalies arising from these circulatory patterns – not unusual in themselves – are now being amplified by background planetary heating caused by human modification of the atmosphere.
In line with climate predictions, affected land surfaces are now rapidly transforming to new states: at least 1400 Swiss glaciers have halved in mass since the 1930s.
