Putting the hot & dry summer of 1976 into context

50 years after the extreme summer for the UK and Ireland, what can we still learn?

A new all-electric double-decker Climate Stripes bus has started taking passengers around Reading today.

The bus shows the warming stripes for Reading back to the 1860s and will hopefully help start climate conversations amongst passengers.

Think Reading managed one dry day otherwise we would be the same.

26 days in a row with rain in Reading. Longest such sequence on record in observations at the University going back to 1908.

Sustainable transport 🤝 Climate communication

As Reading continued to experience the longest unbroken spell of rainfall ever recorded in the town, it was fitting that Reading Buses were launching a new fleet of electric buses, including this beauty featuring the #ClimateStripes ♥️

Rising GHGs create a TOA energy imbalance - less heat escapes to space

Predicted fingerprints: tropospheric warming, stratospheric cooling, ocean heat uptake

Observed reality: 11 warmest years since 1850 are in the last decade

Theory → prediction → observation

Climate ‘fingerprints’ mark human activity from the top of the atmosphere to the bottom of the ocean
The ocean is warming as the upper atmosphere is cooling – both as a result of excessive greenhouse gas emissions.

Higher up, where the air is thin and very little heat arrives from below, extra CO₂ allows the stratosphere to lose more heat to space than it gains, so the stratosphere cools.

Another factor is the destruction of stratospheric ozone by CFCs, which has also cooled the lower stratosphere.

Why is there this pattern of temperature change?

The concentrations of greenhouse gases have increased throughout the atmosphere, making the atmosphere more efficient at absorbing and giving off heat. In the lower atmosphere, this effect acts as a blanket, retaining more heat & warming the surface.

Warming stripes for different layers of the atmosphere and ocean from 1960-2025. The ocean and troposphere are warming, the stratosphere is cooling.

A data-driven mosaic of our warming planet - now updated through 2025 🥵

Download graphic at zacklabe.com/climate-chan...
Heat map-style graphic showing monthly mean global surface air temperature anomalies from January 1850 to December 2025. There is a long-term warming trend evident in each month. Blue shading is shown for colder months, and red shading is shown for warmer months. Annotations are shown for the year of each warmest respective month. All of these records have occurred within the 2023 to 2025 period in this dataset. Anomalies here are calculated relative to a 1850-1900 baseline. Data is from NOAA/NESDIS/NCEI NOAAGlobalTemp 6.0.0.

Agree this looks really bad. What’s the solution? UKRI to effectively cover the extra ‘unavoidable’ costs from exchange rates, labs etc?

I'm not involved with the recruitment, but I would love to see applications from senior mid-career scientists with clear ideas & enthusiasm to develop them over an extended period. This is an amazing opportunity to come to Reading and build deep collaborations across weather & climate science.

I think the policy community would benefit from knowing earlier to (potentially) add urgency to discussions (for some nations).

What does 1.5°C even mean anyway?

Lengthy new community effort to discuss definitions, meanings, uncertainties & monitoring how close we might be to global temperature levels given in the Paris Agreement.

How well can we quantify when 1.5 °C of global warming has been exceeded?
Abstract. Parties to the 2015 Paris Agreement agreed to limit the long-term increase in global average temperature to well below 2 °C and pursue efforts to keep temperatures below 1.5 °C relative to p...
