Dave Throup @davethroup.bsky.social · 19/04/2025Rainfall distribution has been very uneven over the last week. Some SW parts have seen well over 100mm, while central areas very little if any. After a few more unsettled days (where rain will mainly fall over the same areas) it’s likely to turn much drier again till month end. 1212

Dave Throup @davethroup.bsky.social · 07/02/2025The acceleration of heating is very worrying. If you calculated when the 1.5° target will be breached on a 30 year trend in 2005 it would have been 2040. If you project it from current trend it will be over 10 years earlier in 2029. apps.climate.copernicus.eu/global-tempe... 24816
Dave Throup @davethroup.bsky.social · 04/02/2025Unusually, January was colder than average, when compared to the last 30 year climate. However, it would have been entirely normal if we compare it with 1961-90 values. Shows how fast things are changing. 1346
Dave Throup @davethroup.bsky.social · 28/01/2025Met Office three month outlook suggesting a considerably greater chance than normal of mild, wet and windy conditions to dominate, particularly during February & March. Impacts from successive Atlantic storms more likely than normal. 03216
Dave Throup @davethroup.bsky.social · 18/01/2025The chances of limiting global heating to 1.5° died years ago. If we wait until the official definition of 1.5° averaged over 30 years to be reached before taking meaningful action we’ll see individual years of 2-3°. Which is catastrophic. www.metoffice.gov.uk/about-us/new...metoffice.gov.ukRise in carbon dioxide off track for limiting global warming to 1.5°CThe increase of atmospheric carbon dioxide (CO₂) is now incompatible with IPCC pathways which remain below 1.5°C, a Met Office study finds. 12916
Dave Throup @davethroup.bsky.social · 11/01/2025Yes fog considerably lower today - as seen in these 2 from North Hill 131
Dave Throup @davethroup.bsky.social · 11/01/2025Another very decent day above the freezing fog on the Malverns. Fog level was considerably lower than the December display - around 140m today, 350m in December. 2525
Dave Throup @davethroup.bsky.social · 09/01/2025Very timely study published today on the increase in whiplash climate events as a result of global heating. These are rapid transitions from drought to flood and vice versa. They’ve already increased by 50% and projected to double in future. www.nature.com/articles/s43... 422779
Dave Throup @davethroup.bsky.social · 09/01/2025Only occasional forays here I’m afraid. Can’t manage 2 feeds! 110
Dave Throup @davethroup.bsky.social · 07/01/20254th large flood of the season today in Worcester. 312610
Dave Throup @davethroup.bsky.social · 27/12/2024One of those special days on the Malvern Hills. Temperature inversion and fog. 3658
Dave Throup @davethroup.bsky.social · 27/12/2024Some remarkable sights on the Malverns this afternoon. When I was there inversion level was about 350 metres. Photo taken on top of Pinnacle Hill at 357m and the only thing poking out of the fog south of the Wyche Cutting. 5°C in the fog, I reckon 12°C above it. 15311
Dave Throup @davethroup.bsky.social · 24/12/2024Very nice Worcestershire sunset as the mist was rising 0544
Dave Throup @davethroup.bsky.social · 24/12/20242024 saw multiple heat and rainfall records across the UK as the atmosphere continues to warm primarily due to human carbon emissions. 2025 will undoubtedly see more. www.metoffice.gov.uk/blog/2024/re... 14311
Dave Throup @davethroup.bsky.social · 18/12/2024Malvern Hills District Council are responsible for checking and enforcement of planning conditions and I don’t know what involvement they’ve had (if any). But this site seems to back up @WildJustice_org findings. Anyone with similar or (hopefully) different experience? Ends. 3130
Dave Throup @davethroup.bsky.social · 18/12/2024In summary, this site has delivered almost none of the promised environmental outcomes after 8 years. Yes, it looks quite nice and provides useful green space but the only real benefit to wildlife is the developing area of scrubland as a result of zero maintenance! 1122
Dave Throup @davethroup.bsky.social · 18/12/2024Wetland bits. A green drainage scheme was constructed but does not function as a wetland. Levels are all wrong. Bone dry 95% of the time, occasional ponding in extreme rainfall. No chance of ever being a functional wetland area. 130
Dave Throup @davethroup.bsky.social · 18/12/2024Trees 5 of the original 25 standard trees specified on the plan survive. Three maples in the eastern corner give a glimpse of what could have happened with some maintenance. Nice informal clump with thriving native shrubs beneath. 130
Dave Throup @davethroup.bsky.social · 18/12/2024Woodland planting areas. Nope Not had any maintenance since planted. All planted trees have died, some shrubs survive but bramble encroachment is extensive. Some self set sycamores thriving. Almost impossible to access now! 130
Dave Throup @davethroup.bsky.social · 18/12/2024Wildflower area. Nope. A few early attempts were made to mow it but not in the last 5 years. Brambles, perennials and some woody shrubs rapidly turning it into scrubland. Not bad habitat but definitely not wildflower meadow promised which needs specific management. 130
Dave Throup @davethroup.bsky.social · 18/12/2024A very nice seating area with nicely trimmed native shrubs and stunning views of the Malverns. Again, very well used by locals. And then there’s the path to nowhere. No idea why but it was on the plans so they did it! So far so good. But … 120
Dave Throup @davethroup.bsky.social · 18/12/2024So 8 years or so later, how have we done? There is a nice area of amenity grass, well used by local kids and dog owners and regularly mowed (whether it needs it or not). Well manicured perimeter hedge. 120
Dave Throup @davethroup.bsky.social · 18/12/2024In short the main commitments were an area of amenity grass benches, paths and viewing area a wildflower area areas of woodland tree planting and feature trees a sustainable drainage scheme with wetland plants 130
Dave Throup @davethroup.bsky.social · 18/12/2024As with any significant development, a huge amount of plans accompanied the planning application, including detailed proposals for landscaping and environmental works. These included detailed drawings and schedules of work. 120
Dave Throup @davethroup.bsky.social · 18/12/2024In 2014 Bovis Homes were granted permission on appeal (it was very controversial at the time) to build 45 houses on a greenfield site in Powick, Worcestershire. Work began later that year and the site was complete about 18 months later. 120
Dave Throup @davethroup.bsky.social · 18/12/2024A recent report by @WildJustice_org suggests that developers aren’t delivering promised environmental outcomes on new developments. wildjustice.org.uk/general/lost-n… So I thought I’d put it to the test on a newish housing site close to me. A 🧵 24418
Dave Throup @davethroup.bsky.social · 17/12/2024No, digitised gauge data only back to 1980s. There will be paper records somewhere. There weren’t any 5 metre plus floods in 1973. Recent big floods (2014, 2020,2021) seem result of multiple wet weather events rather than one big one 020
Dave Throup @davethroup.bsky.social · 17/12/2024Huge areas of agricultural land are at risk of flooding from rivers & sea, with 60% of grade 1 land at risk. Amount of land and frequency will increase due to climate change. We can’t afford to protect all homes from flooding, let alone farmland. Difficult decisions ahead. 1143
Dave Throup @davethroup.bsky.social · 17/12/2024Yes, I would think so given the very significant rise in a short timescale. There’s nothing very obvious, such as unprecedented single rainfall events. They appear result from relatively modest 100-150mm over multiple days across upland areas. Maybe intensity has increased? 100
Dave Throup @davethroup.bsky.social · 16/12/2024Yes 2007 is one of the two big floods I refer to on the Avon. 1998 was the other. 100
Dave Throup @davethroup.bsky.social · 16/12/2024Here’s an interesting one. We’ve seen a very large increase in the last 5 years of big floods on the Wye, Teme and lower Severn No such increase on neighbouring Avon - only 2 really big floods in 50 years I suspect it may be due to the different weather setup needed to produce floods on the Avon. 2202
Dave Throup @davethroup.bsky.social · 14/12/2024Of course. Data on Welsh rivers is harder to come by - there isn’t a portal for historical data that I’m aware of 210
Dave Throup @davethroup.bsky.social · 14/12/2024My own chart. Take data from river gauges via hydrology data explorer environment.data.gov.uk/hydrology/environment.data.gov.ukHydrology Data Explorer 120
Dave Throup @davethroup.bsky.social · 13/12/2024Don’t think there is unfortunately. And I’ve still got 30x more followers on Twitter so it’s tricky! 110
Dave Throup @davethroup.bsky.social · 13/12/2024Major floods on the Severn, Teme & Wye Updated in light of another big one on the Wye last week. Current 5 year period 3x more than any previous period in last 30 years. We can either hope it goes away or start adapting. Fast. 24823
Dave Throup @davethroup.bsky.social · 13/12/2024Gosh - just checked on here and nearly a thousand folk have chosen to follow me. So I feel obliged to post a bit! Twitter will still be my main platform but I’ll do a bit here and try to answer questions ( I’m assured it’s a less confrontational place!) 12695
