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

Japan Wants a Bigger Role In Science of Extreme Weather Attribution Nation’s new research center aims to pinpoint the role of climate change in heat waves to typhoons

Really good to see a greater effort in Japan to track the influence of climate change on extreme weather. Will be interesting to see how/if this shifts public opinion and debate on climate. www.bloomberg.com/news/article...

Japan embraces lab-made fuels despite costs and climate concerns Japanese utilities say e-methane is chemically almost identical to natural gas but is effectively carbon-neutral.

For Japan’s largest utilities, lab-made fuels are a meaningful step toward greener energy that also extends the life of existing fossil-fuel infrastructure. Their critics says they are an expensive distraction.

Quick announcement: Pleased to say that last week I joined @asia.nikkei.com as a desk editor. I'll be focused on South Asia, but I'm aiming to keep an eye on climate too.

The IEA has released a new analysis on energy use in 2024, and it's full of interesting data and insights.

I urge people to check it out.

Sky not the only limit for JAL and ANA’s climate goals The airlines' similar but different carbon neutrality plans highlight the difficulty of decarbonization, especially as the sector is now growing again.

JAL and ANA both have ambitious climate goals, but slow progress in many areas shows just how challenging decarbonization is for the aviation sector.

Nice working with @gristnews.bsky.social on this story. As someone who has been flexitarian for 5+ years now, I can say myself that the struggle is real when it comes to avoiding animal products. But things are changing — I got a few nice restaurant/bakery tips from this article!

Japan is investing billions of yen to get carbon capture and storage off the ground in order to keep key, high-emitting industries operating, but the technology is dogged by high costs and uncertainty.

Presumably Japan wouldn't fit in at the "peak of inflated expectations"

Today, the Japanese government presented the draft new 2040 generation mix.
40-50% Renewables
20% Nuclear
30-40% Fossil fuel and hydrogen/ammonia
The Japanese government has doubled down on CCS as well as imported hydrogen and ammonia.

Japan sees nuclear and solar as the cheapest energy sources in 2040
🇯🇵☢️

⚡ The total system cost for nuclear power is the cheapest option in all but one scenario
☀️ Solar power could be cheapest or most expensive depending on scale of intermittent renewable sources on the grid

"Expert" panels are ubiquitous in Japan's government, setting policy directions for everything from energy to public health, but are they fair and balanced? @russ-chris.bsky.social and I examined the question through a recent debate over climate policy-related committees. For @japantimes.co.jp

Tokyo's climate goals rely on a fuel that is falling out of favor The metropolitan government is targeting the widespread use of hydrogen, but strong competition and its physical properties are limiting its applications.

How Japan can exit the fossil fuel subsidies it can’t seem to quit While offering relief to low-income households, such measures encourage the continued use of the fossil fuels driving climate change.

Japan has regularly renewed costly energy subsidies since the start of the Ukraine war, but these measures come at a high cost and only encourage the use of planet-warming fossil fuels.
