Amazing new giant virus, found throughout the global ocean !!

Just out: metagenomics with internal standards yields phylogenetically resolved genome ("~cell") counts of bacteria, archaea, and photosynthetic eukaryotes per L of seawater, over the AMT29 Atlantic transect, via "single copy" genes (recA, radA, psbO). Compares with microscopy and flow cytometry.

AlphaFold - A practical guide AlphaFold - A practical guide

Recently I learnt that EMBL-EBI has a free online course about AlphaFold — how it works, strengths and limitations, how to use it — and it's very good!

There are also little quizzes and interactives.

Even if you can’t attend this course in person, the online course materials are free and SO useful (I used this GitHub to plan out content for my new -Omics grad course)

Satellite data archives reveal positive effects of peatland restoration: albedo and temperature begin to resemble those of intact peatlands - IOPscience Satellite data archives reveal positive effects of peatland restoration: albedo and temperature begin to resemble those of intact peatlands, Burdun, Iuliia, Myllymäki, Mari, Artz, Rebekka R.E., Guêné-Nanchen, Mélina, Jarašius, Leonas, Kull, Ain, Lilleskov, Erik A., McCullough, Kevin, Pakalne, Mara, Pu, Jiabin, Sendzikaite, Jurate, Strazdina, Liga, Rautiainen, Miina

New paper out! Using over 20 years of #satellite data, we show that restored #peatlands start to resemble intact peatlands. Their #albedo and land surface #temperature (LST) gradually align with those of natural peatlands.

Indicators of Global Climate Change 2024: annual update of key indicators of the state of the climate system and human influence Abstract. 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.

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
