New preprint out today highlighting that the duration of a 1.5C overshoot matters. We find that all climate tipping points would be avoided if global warming over 1.5C is restricted to 30 years and peak warming kept below 2.5C. doi.org/10.5194/egusph… @coxypm @UofE_Research

Final few days to submit #EGU25 abstracts! ⬇️ meetingorganizer.copernicus.org/EGU25/session/… @chrisroadmap @YQuilcaille @EuroGeosciences

#EGU25 session on Physical and statistical emulators for climate impacts 🌍 Abstracts welcome! ⬇️ meetingorganizer.copernicus.org/EGU25/session/… @chrisroadmap @YQuilcaille @EuroGeosciences

Call for abstracts at EGU 2025: Statistical and physical emulators for climate impacts. If you contribute to the development & application of climate emulators, this is an opportunity to present your and develop your network in the community. meetingorganizer.copernicus.org/EGU25/session/…

In case you work on soil microbial models and missed this. Please share to your colleagues who might be interested #AGU2024 🙏👇

New Research article: Soil carbon-concentration and carbon-climate feedbacks in CMIP6 Earth system models doi.org/10.5194/bg-21-…

Another invaluable paper from the ever productive @rebecca_varney_ @UniofExeter! Soil carbon-concentration and carbon-climate feedbacks in CMIP6 Earth system models bg.copernicus.org/articles/21/27… @PFriedling @semiupsidedown @eleanorjb @met

Scientists from @UniofExeter @metoffice & @imperialcollege have found a new way to calculate the total carbon emissions consistent with the Paris climate targets of 1.5C and 2C of #GlobalWarming Full paper 👉 nature.com/articles/s4146… Press release 👇 news.exeter.ac.uk/faculty-of-env…

New paper by @coxypm, @chrisd_jones, @PFriedling, @NinaRaoult, @JoeriRogelj, @rebecca_varney_ et al. combines #climate simulations with observations to estimate better constrained #CarbonBudgets and finds them >10% larger than the mean from CMIP6 models. nature.com/articles/s4146…

Excited to be a co-author on this new study led by @coxypm! Emergent constraints are used to calculate carbon budgets consistent with Paris agreement targets 🌍

New pre-print on quantifying soil carbon feedbacks in CMIP6 Earth system models, the study also highlights the role of soils within the land response to climate change. With co-authors @coxypm @PFriedling @semiupsidedown @eleanorjb 🌍 @4C_H2020 ⬇️ egusphere.copernicus.org/preprints/2023…

Having fun with the 901ers and friends at the @CarbonBrief annual quiz @rebecca_varney_ @PDLRitchie @NinaRaoult @noahdsmith @chrisd_jones and others

As the carbon budget is shrinking each year, the 4C project provides important information to policymakers to help make decisions to rapidly mitigate CO2 #emissions. @PFriedling, 4C project coordinator, explains more. 👇

Projections of soil carbon during the 21st century in #CMIP6 Earth system models are evaluated in a recent 4C-funded study, under a range of atmospheric composition scenarios. ➡️Read full paper: doi.org/10.5194/bg-20-… #ESMs #climate @rebecca_varney_ (image: Fig. 3 from paper)

Latest paper by @rebecca_varney_ @ExeterUniMaths now published! Projections of future changes in global soil carbon are less uncertain in CMIP6 models compared to CMIP5, mainly due to "false priming" (which is a real thing, btw). bg.copernicus.org/articles/20/37…
