Noniin, kyllähän tuon datan perusteella päästöissä (fossiiliCO2 + maankäyttö) olisi tapahtunut kaksi isoa taitetta. 2000 luvun alussa päästöt kiihtyivät, 2010 luvun alussa ne alkoivat hidastua.
Taitepisteiden kanssa malli sopii aavistuksen verran paremmin kuin ilman. (0.23 vs. 0.34 Gt virhettä)

Good news: 35 countries have decreased their fossil CO2 emissions significantly (p<0.05) while growing their economies in the decade 2015-20244, twice as many as during the previous decade (2005-2014; 18 countries.

These 35 countries account for 27% of global fossil CO2 emissions.

Fossil CO2 emissions continue to rise in 2025 while the terrestrial carbon sink recovers to pre-El Niño strength.

The new 2025 Global Carbon Budget finds that fossil fuel emissions will reach a new high in 2025. Total CO2 emissions (including land use) remain flat at 2024 levels.

While the land sink is up from 2024, carbon sinks are weakening: www.carbonbrief.org/...

A new Nature paper accompanying the Global Carbon Budget finds that the land and ocean sinks are 25% smaller and 7% smaller, respectively, than they would have been without the effects of climate change over 2015-24:

Emerging climate impact on carbon sinks in a consolidated carbon budget | Nature

Despite the adoption of the Paris Agreement ten years ago, fossil CO2 emissions continue to rise, pushing atmospheric CO2 levels to 423 ppm in 2024 and driving human-induced warming to 1.36°C, within years of breaching the 1.5°C limit 1,2. Accurate reporting of anthropogenic and natural CO2 sources and sinks is a prerequisite to tracking the effectiveness of climate policy and detecting carbon sink responses to climate change. Yet notable mismatches between reported emissions and sinks have so far prevented confident interpretation of their trends and drivers 1. Here, we present and integrate recent advances in observations and process understanding to address some long-standing issues in the global carbon budget estimates. We show that the magnitude of the natural land sink is substantially smaller than previously estimated, while net emissions from anthropogenic land-use change are revised upwards 1. The ocean sink is 15% larger than the land sink, consistent with new evidence from oceanic and atmospheric observations 3,4. Climate change reduces the efficiency of the sinks, particularly on land, contributing 8.3 ± 1.4 ppm to the atmospheric CO2 increase since 1960. The combined effects of climate change and deforestation turn Southeast Asian and large parts of South American tropical forests from CO2 sinks to sources. This underscores the need to halt deforestation and limit warming to prevent further loss of carbon stored on land. Improved confidence in assessments of CO2 sources and sinks is fundamental for effective climate policy.

It might be that IEAs scenarios are not keeping up with the insane investment plans for new data centers. So it's also the rate of planned growth which is concerning.

When I learned programming in the 90-00s, we had to be scarce with resources. A lot of the tips were around computationally efficient ways of solving things and clearing memory. I think a lot of current computing is just hogging resources.

Tuomas Mattila @tuomasjmattila.bsky.social · 2d

And the belief is that the extra AI would use that computation to build benefits which are much larger than the investments.

Note from an irritated editor: AI is starting to infiltrate peer review, or at least it looks a lot like it. If you’re planning to use an LLM to review someone else’s work for a journal, rather just don’t accept the review invitation. It’s easy.

This is correct. GPUs are 35% of data center costs and on a 3 yr depreciation curve. Yield is not perfect and many die from heat. NVDA will have new generations of GPU every year through 2029.

Yet companies are borrowing at private credit rates for data centers that won't open for 3 years.

Joyce Carol Oates
@Joyce... 17h O
So curious that such a wealthy man never posts anything that indicates that he enjoys or is even aware of what virtually everyone appreciates— scenes from nature, pet dog or cat, praise for a movie, music, a book (but doubt that he reads); pride in a friend's or relative's accomplishment; condolences for someone who has died; pleasure in sports, acclaim for a favorite team; references to history. In fact he seems totally uneducated, uncultured. The poorest persons on Twitter may have access to more beauty & meaning in life than the
"most wealthy person in the world."
