Here in the North West of England, the home of water, we have the very unusual event of a hosepipe ban and the reservoirs are well down. There was a dry spell in Spring but since then it seems to have rained a reasonable amount without making up the loss. At this moment the whole of the UK is in a block of cooler air because the jet stream has moved over France.
In East Europe there is a heatwave that has lasted several weeks and at the boundary of the heat wave over Asia colder air has caused torrential rain that is flooding Pakistan. This also seems to be driven by the jetstream moving south.
Areas of the USA, South America, China and Australia are having exceptional weather and some say the change from La Nina to El Nino in the Pacific is causing upset effecting the overall climate.
Temperatures and extreme weather events seem to be on the increase which appears to match expectations of climate change. Yet fluctuations in climate are not unusual. Potential food shortages caused by reduced grain harvests might also manifest in greater instability in the world. At this moment it appears there is increasing evidence to support greater investment in preventing climate change, even if the evidence isn’t conclusive. Certainly this years weather has been very unusual.
