at 2.2 km as well as a regridded version at 5 km spatial resolution in the Ordnance Survey’s British National Coordinates. The latter underpins the FUTURE- DRAINAGE uplifts (Dale et al, 2021) and the Environment Agency’s rainfall allowances tool 1 . For both 2 km and 5 km datasets, the issue can

in the changing likelihood of extreme heatwaves. Extreme events are defined as exceedances of the previous record anomaly of 4.126 0C (relative to 1901-1930) observed in year 2003. Temperature observations come from the CRUTEM5 2 dataset (Osborn et al., 2020) and cover the period 1851-2021. The model

of the June temperature anomaly (relative to 1901-1930) in the reference region (5W-13E; 38-52N) computed with observational data from CRUTEM5 (black line) and the CMIP6 ALL (red lines) and NAT (green lines) simulations. The models were evaluated against the observations (Fig. 2) by applying a number

Arctic sea ice minimum Arctic sea ice extent reached its seasonal minimum of 4.59 million square km on both 19th and 23rd September 2018 (Figure 1), according to data from the US National Snow and Ice Data Center (NSIDC). This is the joint-6th lowest minimum in the satellite record (Figure 2

Strong winds November 2019 An area of low pressure brought some very strong winds to south Wales and the south coast of England on Saturday 2 November. Winds gusted at 60 to 70 Kt (69 to 81 mph) in exposed coastal locations. Gusts of 95 Kt (109 mph) were recorded at Needles Old Battery, Isle

Concentration Pathways (RCPs) used in climate models to describe possible futures based on assumptions about green house gas emissions. In RCP2.6 global emissions are strongly mitigated and reduced. Global temperature rise is kept below 2°C. In RCP8.5 global emissions grow unmitigated and global
