New study:

Total and direct shortwave (SW) radiation rose by 3.5 and 9.3 W/m²/decade from 1996-2021 over Germany.

In contrast, CO2 forcing only added 0.2 W/m²/decade since 2000 (nature.com/articles/natur…).

SW forcing thus explains recent warming best.

New study:

Evaporation is supposed to increase with warming. But 'observation results around the world have shown that evaporation has been steadily declining since the 1950s' - the 'evaporation paradox'.

So either models are wrong or it hasn't warmed.🤔

New studies:

Modern (2000 CE) Azores air temps average 10-11°C. Medieval times were 13-15°C, 3-4°C warmer.

Today's N. Finland's temps (🔹) are nearly the coldest in 8000 years. It was much warmer 1500-1200 and 7000-3000 years ago.

New study:

Scientists: 150 million-yr-old Iran stomata samples re-confirm CO2 levels then hit 1,100+ ppm.

97,404 stomata measurements from 901 stations (292 papers, 1800-1959) show CO2 hit 380 ppm in 1943. These data are rejected.

New study:

13,000+ global islands were assessed for coastal change since 1990. 93% of coasts were stable or grew seaward.

Coasts grew (net) seaward 402 km² from 2000-2020. For islands losing coastal area, sea level rise was 'not the predominant' factor.

New study:

9000 to 6000 yrs ago Antarctica's Collins Glacier's frontline gradually retreated south, reaching today's extent ~5000 yrs ago (Image 1). It continued retreating 4000 more yrs, peaking 1000 yrs ago (Image 3). It's rapidly glaciated since then.

New Pakistan temperature reconstruction (1812-2018):

'The longest 10 years’ warm periods were observed during...1918–1927'

'five hottest years...were 1896, 1892, 1898, 1871, and 1925'

'Our reconstruction failed to capture the recent warming trend...'

New study:

The 1987 Montreal CFC bans did 0⃣ to reduce ozone holes.

There's been 'continued, significant ozone reduction since 2004, amounting to 26% loss in the core of the ozone hole.'

'5 of the past 8 years overall have exhibited record ozone holes.'

New study:

The 4 W/m² uncertainty in 1850-present natural wildfire emissions/dust aerosol forcing is >2x larger than total CO2 forcing since 1750 (1.82 W/m²).

Wildfire aerosol forcing alone is -2 W/m² in the 'current climate,' canceling out CO2 forcing.

New study:

↑ fossil fuel emissions are claimed to lead to ↓ carbon isotope 13 (δ13C) trends.

But multiple data sources show ↑ trends in δ13C (input) over the last decades, centuries.

Thus, δ13C is 'not affected by increases in human CO2 emissions'.

New study:

The USA's NW, SW, Texas/Mexico, Great Plains have undergone post-1500s temperature changes that do not correlate with a sharp post-1940s increase in human CO2 emissions.

Scientists nonetheless insist any 'warming' here is human-CO2-caused.🤔

New study:

Absorbed shortwave irradiance has been increasing since 2000 at a rate of +0.68 W/m² per decade.

This explains why the top of atmosphere (TOA) energy imbalance has been 'increasing with time', and the imbalance 'leads mostly to heating ocean'.

3 new studies:

There's been no CO2-induced precipitation trend detectable for 1770-2020 (SE USA), 1858-2015 (Türkiye), and 1896-2016 (E China).

1960-2020 (SE USA) had the lowest intense rainfall event rate.

New study:

Qinling-Bashan Mtn (QBM) annual temps have cooled since 1960.

Summer temp variations 'are associated with solar activity, the El Niño-southern oscillation (ENSO), the Pacific decadal oscillation (PDO), Atlantic multidecadal oscillation (AMO)'.

New 1787-2005 NE China temperature reconstruction determines the coldest 50-year period was 1940-1993, whereas the warmest 50-year period occurred from 1844-1893.

The temperature variations reportedly coincide with variations in solar activity.

New study:

Greenland's interior ice flow has been assumed stable for 10,000+ years. Instead it's been highly variable, changing course, magnitude in only centuries.

Ice streams 'come and go' via internal, 'spontaneous' processes.

New study:

The elevation of W. Antarctica's ice sheet fell by ~480 m within just 200 yrs ~8,200 yrs ago, a drop of >2 m per yr.

There was also 270 km of ice area retreat within only 400 yrs ~7,300-7,700 yrs ago.

No modern retreat rates are comparable.
