• Mauna Loa carbon dioxide forecast for 2020

  observations (black), our statistical reconstructions and past forecasts (blue) and 2020 forecast (red). The forecast uncertainty range based on the SST forecast (solid red line) is ± 2 standard deviations. Uncertainty in the 2019 emissions increases the total uncertainty slightly (dashed red line

• Storm Dave in context: How the storm unfolded

  rainfall, with the highest totals focused across western Scotland, parts of northern England, Cumbria and some western upland areas elsewhere. The highest rainfall totals during the storm was recorded at Glen Ample in Stirling, where 50 mm fell. Several other sites across Argyll and the western Highlands

• Mauna Loa carbon dioxide forecast for 2019

  .  This is reflected in our uncertainty estimates. Estimates from the Global Carbon Budget suggest that although fossil fuel emissions increased in 2018 compared to 2017, emissions from land use change declined by approximately the same amount. Therefore the total anthropogenic CO2 emissions did not change

• Met Office daily weather: Unsettled with rain and cooler conditions for many

  to the day across Northern Ireland. Wet and blustery. Heavy rainfall totals building up as we go through the day. And heavy rain also pushing into parts of western, southwestern Scotland in particular. Now, we do have a couple of warnings out. Rainfall totals especially across southwest Scotland

• Met Office daily weather: Weather warnings issued as Storm Claudia set to impact parts of the UK

  heavy rain and strong winds. “It's worth noting that the winds coming in more from the east. And that's pivotal to where we're going to see those highest rainfall totals building up. It's going to be around some eastern facing higher ground, particularly across parts of Wales, southeast Wales

• New March sunshine records

  average for the month, with a total of 192.5 hours of sunshine in the month. Scotland was similarly sunny, with 64% more sunshine hours than average, with a total of 160.1 hours. That sunny and clear picture was replicated across much of the UK. England had its second sunniest March with 168.1 hours

• Global humidity reached record levels in 2024, says latest climate report

  – the amount of water vapour in a parcel of air - reached record levels over both land and ocean last year. Relative humidity – a measure of the saturation of a parcel of air – also reached higher levels than in 2023. Total column water vapour – the total amount of water within the atmosphere above the surface

• Rain on the horizon, but dry conditions likely to persist for many

  the UK during Saturday night and Sunday morning, showers then following in the north later Sunday where they could be locally heavy.  Rainfall totals are expected to be mostly small away from western and north-western Scotland where 10-20mm of rain is likely, with locally higher totals in the most

• Relative operating characteristic (ROC)

  with a range of 'trigger' thresholds (triangles) are plotted. The vertical axis gives the hit rate, defined as the number of times the event was forecast (with probability above a certain threshold) and later observed to occur. The hit rate is expressed as a ratio of the total number of occasions on which
