Our new paper updating key metrics in the IPCC is now out, and the news is grim: ⬆️ Human induced warming now at 1.36C ⬆️ Rate of warming now 0.27C / decade ⬆️ Sharp increase in Earth's energy imbalance ⬇️ Remaining 1.5C carbon budget only 130 GtCO2 essd.copernicus.org/...

essd.copernicus.orgIndicators of Global Climate Change 2024: annual update of key indicators of the state of the climate system and human influenceAbstract. In a rapidly changing climate, evidence-based decision-making benefits from up-to-date and timely information. Here we compile monitoring datasets (published at https://doi.org/10.5281/zenodo.15639576; Smith et al., 2025a) to produce updated estimates for key indicators of the state of the climate system: net emissions of greenhouse gases and short-lived climate forcers, greenhouse gas concentrations, radiative forcing, the Earth's energy imbalance, surface temperature changes, warming attributed to human activities, the remaining carbon budget, and estimates of global temperature extremes. This year, we additionally include indicators for sea-level rise and land precipitation change. We follow methods as closely as possible to those used in the IPCC Sixth Assessment Report (AR6) Working Group One report. The indicators show that human activities are increasing the Earth's energy imbalance and driving faster sea-level rise compared to the AR6 assessment. For the 2015–2024 decade average, observed warming relative to 1850–1900 was 1.24 [1.11 to 1.35] °C, of which 1.22 [1.0 to 1.5] °C was human-induced. The 2024-observed best estimate of global surface temperature (1.52 °C) is well above the best estimate of human-caused warming (1.36 °C). However, the 2024 observed warming can still be regarded as a typical year, considering the human-induced warming level and the state of internal variability associated with the phase of El Niño and Atlantic variability. Human-induced warming has been increasing at a rate that is unprecedented in the instrumental record, reaching 0.27 [0.2–0.4] °C per decade over 2015–2024. This high rate of warming is caused by a combination of greenhouse gas emissions being at an all-time high of 53.6±5.2 Gt CO2e yr−1 over the last decade (2014–2023), as well as reductions in the strength of aerosol cooling. Despite this, there is evidence that the rate of increase in CO2 emissions over the last decade has slowed compared to the 2000s, and depending on societal choices, a continued series of these annual updates over the critical 2020s decade could track decreases or increases in the rate of the climatic changes presented here.

Wrote an article for the latest WSRS magazine on identification of individual bittern in local clay pits using sound recording and the vulnerability of this population to climate change. Some snippets: #lowcarbonbirding #lowcarbonsoundrecording

Would recommend WSRS membership for anyone interested in sound recording. I particularly like reading and listening to sound recordings and projects from the other side of the world without the carbon cost of flying there. It really feels like you are there.

Willow tit, Threave, Dumfries&Galloway. Notable that their territory fell within young or coppiced willow and without singing blue and great tit which were instead within high woodland close by. Collecting moss for nest. Now a distant memory for NLincs.

@birdingclimate.bsky.social

Yes, a public information campaign on the climate crisis is vital. But why should politicians believe there is popular support for this when organisations like @rspb.bsky.social –the largest conservation charity in Europe– isn't informing its own members? Thread on RSPB and climate communication

Prof Bill McGuire@profbillmcguire.bsky.social

Please sign up. This is vital I have been demanding and writing about this for years We have campaigns on every safety issue imaginable - except the biggest ever threat to civilisation

Gold dust. After failing to find one last year at Carstramon, very pleased to find WO singing late morning. Still clinging on. iPhone recording here - gear packed for early morning session tomorrow. Sitting in a wood full of common birds with no background noise is the most precious of things.

1/10 Let's say you're a scientist, a retired scientist, a technician, a teacher of science, perhaps somebody who studied science at school or university, who then went on to work in a career with very little connection to science.

North Lincs Council once again displaying its woeful grip on numbers: 😳 The Council’s own carbon emissions are just 0.1% of those of all of North Lincs. 😠 They have NOT set a target of Net Zero 2030 for all of North Lincs. 😡 They have NOT declared or act like there is a Climate Emergency.

No home makeover as cottage boasting ‘stunning views of the Humber’ according to Rightmove is no more. Will miss it as a landmark. 9 snow bunting just west of Goxhill haven on my late Humber WEBS count along with a few gangs of fieldfare, redwing and starling heading east.

You are up to date.
