New study:
Per empirical data CO2 residence time is 3-7 years. 90% of human emissions since 1750 have thus already been removed, precluding a human-CO2-driven climate.
The IPCC consequently uses model assumptions to claim residence time is >100 years.
doi.org/10.53234/SCC202501/0…
New study:
The common practice of attributing the post-1750 rise in atmospheric CO2 entirely to fossil-fuel combustion is mathematically inconsistent with available isotopic data.
Using Keeling plot analysis on instrumental records and historical reconstructions, the study finds a stable carbon isotope intercept (𝛿13C𝐼) dating back to 1500 AD despite a 10,000-fold increase in human emissions. Human activity thus cannot be the main cause of atmospheric CO2 changes.
“Fossil carbon is a negligible component of the net atmospheric CO2 addition.”
The authors' conclusion is derived from IPCC-endorsed data and rest on mathematical certainties. Thus, critics cannot dismiss it without explicitly rejecting foundational principles of arithmetic and mass conservation, standard isotopic values, or the primary measurement datasets themselves.

West Antarctica's Thwaites Glacier (TG) is believed to be catastrophically melting due to recent regional circumpolar deep water (CDW) warming caused by human activity.
But two new studies indicate:
TG would continue melting for another 150 years even if the CDW cooled, as a warming CDW does not drive TG melt (agupubs.onlinelibrary.wiley.…). A belief that policy choices control TG melt is thus not supported.
The "significant" regional CDW warming amounts to only 0.1°C from the 1990s to 2010s (with -0.1°C cooling also regionally present, offsetting the warming). The warming (and cooling) have been ~100% "driven by wind-forced circulation changes," not human activity (agupubs.onlinelibrary.wiley.…).
New study:
There has been "cooling of the Pacific sector on decadal timescales during 1940-2020," including robust cooling reaching -0.4°C per decade from 2005-2019 (even "exceeding -0.9°C per decade during 2005-2010").
But this is still global warming.

New study:
Net climate sensitivity to a 24 ppm decrease in atmospheric CO2 by 2070 (achieved via China's transition to "net zero" emissions alone) is just -0.03°C ±0.09°C, as global cooling from a 24 ppm CO2 reduction (-0.16°C) is offset by global warming from China's concomitant air pollution reduction (+0.12°C). Ambitious CO2 reduction policies ("net zero") thus have almost no effect on climate "for half a century".
"Even aggressive climate policies like carbon neutrality are not sufficient to cool the planet by ~2070 due to the competing effect of air pollutant reduction."

New study:
7000-6000 years ago biomarker evidence embedded in rock suggests Brazilian sea level was >2 m (3-3.5 m) higher than today.
This region was largely unaffected by post-glacial uplift, so this likely represents the Holocene eustatic sea level.

New study:
Marine organisms embedded in coastal rocks dating to ~6500 years ago indicate Northern Ireland's sea levels were 7.8 m higher than today at that time.
As recently as 3400 years ago sea levels were still no lower than 5.6 m higher than today.

New study:
The warm/hot Earth/Venus surface temperature is mostly due to convective heat transfer establishing the lapse rate, not LW radiation or greenhouse gas (CO2) differential/variation.
In the real atmosphere, "radiative equilibrium never appears".

A new study finds no acceleration (even slightly negative, -0.0003 to -0.00005 yr¯²) in global drought throughout 1900-2024, 1950-2024, and 1981-2024.
Scientists historically used negligent statistical methods to artificially inflate drying trends 6-fold.

Earth's optimal climate is 5°C warmer than today.
"Earth's global mean surface temperature of 14°C"
"the optimal temperature of a superhabitable planet as proposed by us (19°C)"

The Holocene Climate Optimum was indeed 5°C warmer.

New Study:
Coral SST proxy evidence shows the northern South China Sea (nSCS) would warm/cool by 1-1.5°C/decade ~5200-5100 yrs ago.

A 2021 coral study indicates ~6000-2000 yrs ago nSCS annual SSTs were 3-4°C warmer than 1994-2004.

New study:
From 2020 to 2024 the Antarctic Ice Sheet gained mass at a rate of +67.5 Gt yr¯¹, reversing the 2003-2019 mass loss (-100.6 Gt yr¯¹) trend.
This recent 5-year mass gain trend was driven by a massive increase in snow and ice accumulation (SMB).

Scientists:
Deglaciation periods had 12,000-20,000 ZJ (zettajoules) of global ocean heat uptake/excess stored energy. This range is 20-30 times more than exists today.
1000 years ago (MCA) ocean heat uptake dipped to 1500 ZJ.
Today it's just 500 ZJ.

New study:
The "implications of climate change" has meant Antarctic Ice Sheet (AIS) glacier melt added a total of just 0.74 cm to sea levels from 1992-2020.
The study assesses 203 glaciers in the AIS Western Peninsula and documents a rising surface mass balance (SMB) trend since 1980 and stable to slightly positive glacier elevation change (+ 0.02 m per year) from 1989 to 2020.

Interesting. The news-making Nepal-Himalaya region has had as-warm or warmer periods than recent decades in the 1600s, 1700s, 1800s.

"Our reconstruction did not show any increasing term trend over the last four centuries."
Another new study shows no net warming in Pakistan's Western Himalayan region since 1855.

2025 study:
"data on CO2 cannot be explained by the model of the greenhouse effect [GHE] as the driver for temperature"
"there exists no unequivocal experimental evidence for the CO2 GHE"
"feedback [from added CO2] is empirically found to be negative [by a factor of 2]"
"On a contemporary timescale, it is clear why the temperature has risen so little compared to the GHE model; CO2 simply does not have a large enough effect on temperature."

New study:
CO2 changes are observed to lag temperature changes (warming) via soil respiration since 1979 (r = 0.74). The uni-directionality is T→CO2.
Anthropogenic CO2 accounts for 4% of the carbon cycle and CO2 just 4% of greenhouse gases (96% water vapor). Thus, "an increase in anthropogenic CO2 since the [1700s] has contributed too little to affecting the global CO2 concentration."
"...we conclude that changes in plant decomposition and [soil respiration] due to global temperatures primarily control global CO2 cycles."

In 1976 the US ended their swine flu shot campaign (43 million were "immunized") after 1 extra paralysis case per 100,000 was linked to it (en.wikipedia.org/wiki/1976_s…).
In contrast, those who received a COVID shot in 2021-'23 may have a 27% increased risk of all cancers per a South Korea population (8.4 million) cohort study.

New study shows scientists changing a 30-year non-warming trend into a split 0.9°C/decade warming and -0.1°C/decade cooling (a net 8°C/century warming rate) by selecting favorable start and end years. This allows them to explicate their "conceptual understanding" of the consequences of warming.

New study:
Since monitoring began 40 years ago, there has been no significant overall net change in coral cover throughout the Great Barrier Reef.
link.springer.com/content/pd…
The GBR was ~1°C warmer and sea levels were ~1 m higher than today throughout much of the last 2000 years. Declines in coral cover are associated with cooling periods and coral growth is linked to warmer SSTs and higher sea levels.
