Why, with global warming, has there been rain here in UK with temperatures under 20C throughout Summer?

Global warming refers to the long-term trend of increasing average global temperatures due to human activities, mainly the release of greenhouse gases into the atmosphere. While global warming can lead to overall warmer temperatures, it can also have complex and varied effects on regional weather patterns.

Several factors can contribute to cooler and rainy summers in the UK, despite the global warming trend:

Jet Stream: The position and strength of the jet stream can greatly influence the weather in the UK. The jet stream is a fast-flowing, narrow air current high up in the atmosphere that separates warm air masses from cold air masses. It can meander and become stuck in certain patterns, which can lead to prolonged periods of wet and cooler weather in the UK.

Ocean Currents: The UK's climate is significantly influenced by the North Atlantic Drift, which is part of the Gulf Stream. Changes in ocean currents can influence the distribution of heat and moisture and impact the weather in the region.

Regional Climate Variability: The UK experiences natural climate variability, which can lead to variations in weather patterns over time. These natural fluctuations can temporarily counteract or amplify the effects of global warming.

Atmospheric Circulation Patterns: Patterns like the North Atlantic Oscillation (NAO) can have a significant impact on the UK's weather. Positive NAO phases are associated with a stronger jet stream, which often leads to wetter and cooler conditions in the UK during summer.

Local Factors: Localized weather patterns, such as sea breezes, coastal effects, and topography, can also play a role in determining the weather in specific regions of the UK.

It's essential to remember that while global warming may increase the likelihood of extreme heat events and other climate-related impacts, it doesn't mean that every summer will be hotter or devoid of rain. The climate system is complex, and various factors can lead to variations in weather conditions, even during a period of global warming.

While I believe Jet Stream can be the main reason behind the July weather in UK.

Because it’s bullshit, they modify the weather!
They also lie about the temperatures or allow us to think it’s way hotter abroad by using the same tactics they used with covid deaths, so they can tax us more and then lock us down!
Agenda 2030!

People are too thick to understand what’s coming!

Because the jet stream is out of whack and not where it's supposed to be.
While it normally lies to the north of the UK at this time of year, it is presently positioned to its south, meaning Europe is being subjected to low pressure and more unsettled conditions than the continent is typically accustomed to, explaining both the damp squib of the British summer and the dangerous temperatures seen in Italy, Spain and Greece.

Surely by now no-one should so confused about it.

The answer comes down to very simple physics.

The term "global warming" is a rather poor one for climate-change; but a mean, worldwide rise in atmospheric and sea temperatures of even only a couple of degrees Celsius, indicates a vast increase in the heat available to drive weather systems.

Further, as the adjective "mean" shows, the heat and temperature distributions, and rates of change, are not uniform around the globe.

Hence irregular seasons, unseasonably cold or hot, wet or dry weather; and more frequent, more severe individual weather events.

Because its not global warming, ITS CALLED WEATHER

Because it's global not local.

BTW recently the highest "recorded" global water temperatures was set for the month of July....

Now that's going back more than 100 years. Yet much of that is because both poles are melting.

@Patriot96 says True, as far as it goes. One season across the UK is indeed "weather" not "climate."

@FaithfulTalia says True. Averaging a hemisphere over a month can give an indication.

Global climate is weather averaged over the whole earth, and also averaged over time; a five to ten year moving average provides a pretty stable output and is a good measure of climate.

DUUUDE!!!
Reducing greenhouse gas emissions such as CO2 & methane; surely you've heard of this?

And, truth be told, we're making progress!!

Current average atmospheric CO2 levels: 417.2 parts per million. That's about 50% higher than pre-industrial levels. In 1990, average CO2 levels were about 355 ppm.

https://essd.copernicus.org/articles/14/4811/2022/

The Paris Accords set a limit on temperature rise. The Accords agree to limit global temperature rise this century at 1.5 degrees Celsius above pre-industrial levels.

For large industrial countries like the US, that means cutting its greenhouse gas (GHG) emissions to about 50% below 2005 levels by 2030.

In 2005, US CO2 emissions were 19.5 metric tons per capita. In 2021 we emitted 14.24 metric tons per capita That means the US is more than half way to the Paris Accords emission level.

Lemme repeat that - the US CO2 emissions cuts are already more than half way to the Paris Accords levels!

We are doing pretty well, and the dire economic predictions of the anti-environemental extremists are proven false.

I think the approach by science and activists regarding climate change has been misguided. Arguments over the validity were always going to split public opinion and any forecasts about global disaster were bound to experience pushback (just as any arguments about Brexit by the remain camp were labelled "Project Fear" by the anti-EU leave supporters, who won out in the referendum). Added to that, big predictions of certain doom were going to be laughed off when the time came and the world didn't actually end. Climate change deniers were always going to jump on a few false claims to prove the entire debate was a hoax.

A much better approach would have been to say, "Look, it's agreed that the globe's fossil fuels will be severely depleted by 2060. Look at your children and your grandchildren. Can we all agree that we need to start switching to new forms of green, clean energy so we can secure their comfort and safety when they grow and have families of their own? Let's work together to make a start on our global move away from fossil fuels, for the sake of our kids."

That might have coalesced into an intelligent consensus of opinion, dampened down any friction and opened a way for people with radically different views to work towards something positive for the future generations. Warning people and waggling a finger never works. Doomsayers get laughed at and ridiculed as End-of-the-World pseudoscience cranks and/or authoritarian grifters after more tax revenues. Now, our grandchildren might look back at us and say, "Thanks for using it all and leaving us with nothing."

There really isn't a need to explain the difference between weather and climate anymore, is there?

I think our part in climate change is mostly unpredictable, much like the weather tends to be anyway.

I’d love some rain we just keep having heat waves, I’m ready for the fall already ahah

ReaD some articles on how it changes weather patterns

@Oldanglaisadverbs 🤷‍♂️just the good old british weather up and down

Same here. Unseasonably cool and wet overall.

Well one of the reasons for the rain is because as ocean levels rise they take up more area. And that bigger area is a bigger area for evaporation and more evaporation = more rain. Cheers!
