if we inadvertently find ourselves in cloud? When did we last practise with London Centre / D&D on VHF 121.5MHz? • Ensure careful monitoring of fuel, distance, speed and elapsed time when dealing with delays from encountered weather. • During take-off for this flight, be ready to deal with gusts

. As a global community we are committed to further warming and impacts, even if we were to reach Net Zero globally tomorrow. We have failed to reduce emissions quickly enough and are failing to adequately manage risk. Recent research at the London School of Economics and Political Science (LSE) considered

(9.5 to 9.9 °C) compared to cooler inland areas (8.0 °C and 9.4°C). July and August are the warmest months in the region with mean daily maxima reaching up to 19 °C in southern Dumfries and Galloway and the Clyde valley. These may be compared with 23.5 °C in the London area. Instances of extreme high
