Do you have a chart of the GHG emissions profile out to 2100? I am guessing this is unreasonable consistent with the latest UN gap report conditional NDCs +all net zero pledges. The amount of removals needed makes me sceptical regarding the actual feasibility.

To clarify, are you referring to 1.5Β°C by 2100 and therefore an overshoot scenario?

The UK hasn't experienced a severe drought since the '90s or an extreme one since the '70s. This has led to complacency in drought preparedness. With climate change, future droughts could be worse than anything previously experienced.

High warming rate fuels record-breaking weather

The longer our measurements, the fewer record-breaking events we should observe.

The opposite is the case - many more records and higher record margins

I summarise the key takeaways of our β€ͺ@natrevearthenviron.nature.com article in a guest post.

New paper in ERL! We study the importance of resolution for the representation of climate extremes.

We use a new generation of km-scale models to show that many important details about temperature and precipitation extremes are hidden at CMIP6-like resolutions.

Found the quote, thanks. It references this paper using the median of the UN gap report scenario set to define future rates if warning. Having looked at that dataset the median won't include uncertainties in aerosol forcing or ECS.

Did you share the wrong paper? I couldn't find the quote and the paper doesn't look at global climate models.

I agree the place to look is a comparison between observed and modelled ocean heat content. Struggled to find recent work on this but I assume it exists.

If the recent surface temperature warming is broadly inline with model projections but the models don't project the large change in energy imbalance does that not suggest the climate model sensitivity is too high? Or that sensitivity estimates based on surface temperatures is the wrong metric?

Graph showing the ranking for monthly global mean temperature from six data sets between March 2023 and June 2024. Rankings are shown as coloured squares. Red is warmest on record (for that month and dataset), orange is second warmest, deep yellow (a beautiful shade that I want to call cadmium yellow but it's not toxic) means a top five month and pale yellow (the colour of sun faded straw) is top ten. Nothing is outside that range. Every single warmest month in all datasets happened since July 2023.

Updated updated notes on the recent acceleration in the argument about the recent acceleration in warming which may or may not be happening or may only appear to be happening (or not, you idiot). Either way it appeared in the New York Times.

Thanks, John! I really appreciate these summaries. I expect moderate acceleration from increasing forcing, but also a wider range of internal variability as the climate warms - making 23/24 tricky to unpack.

⚠️Global warming caused by humans is advancing at 0.27Β°C per decade – the highest rate since records began.

This is one of the indicators updated every year by over 60 international scientists in the annual Indicators of Global Climate Change report – published today. doi.org/10.5194/essd... /1

New infrastructure should be climate resilient from the Inception. HS2 and Sizewell are reasonable examples for flood risk. There are embedded processes that are starting to address this but they are often superficial and don't go far enough. Certainly more needs to be done.

evidence suggests it does little to manage large floods in big catchments. We need a combination of engineered and natural solutions thinking holistically at catchment scales. Unfortunately flooding is extremely complex - every catchment and every flood event is different with no simple solutions.

There is a strict requirement that government funded flood schemes must not increase risks elsewhere. This is generally done by making space for water and providing large storage areas. Yes, natural flood management and upland reforestation is important to provide resilience but

Natural England produce a Fire Severity Index (FSI) but this needs to be promoted more widely across the media.

FSI models potential fire severity *should they occur*, and rises widely across England to *exceptional* levels by next Monday.

Observed trend in Earth energy imbalance may provide a constraint for low climate sensitivity models Climate models that give a low warming from increases in greenhouse gases do not match satellite measurements. Future warming will likely be worse than thought
