Are glaciers shrinking? What does the photographic evidence say?
Muir Glacier, Alaska
Muir Glacier and Inlet, Alaska, 1880s and 2005
Carroll Glacier, Alaska, 1906 and 2004
Grinnell Glacier, Montana, 1926 and 2008
Bear Glacier from space 1986, 2024
Trift Glacier, Switzerland, has retreated by 1.17 km from 2006 to 2015

Using largely untapped satellite archives, we chart surface elevation changes at a high spatiotemporal resolution over all of Earth’s glaciers. We extensively validate our estimates against independent, high-precision measurements and present a globally complete and consistent estimate of glacier mass change. We show that during 2000–2019, glaciers lost a mass of 267 ± 16 gigatonnes per year, equivalent to 21 ± 3 per cent of the observed sea-level rise6. We identify a mass loss acceleration of 48 ± 16 gigatonnes per year per decade, explaining 6 to 19 per cent of the observed acceleration of sea-level rise.

CO2 & methane are transparent to visible light but more opaque to infrared. The solar energy comes pouring in via the visible spectrum, but the heat can't leave so easily via the infrared spectrum due to that opacity.

With multiple data points we can solve for multiple variables simultaneously. Detailed climate models account for dozens of variables. They are verified and calibrated based on 800,000 years of prior climate data.

The climate data comes from bubbles in glacial ice, and is corroborated by data from lake & sea floor sediments. https://icecores.org/about-ice-cores CO2 & methane & temp data
Here's where the various data sets were collected:
The most salient thing about the 800,000 years of climate data is the rate of change during those previous 7 ice ages compared to the current rate of change this century.
@MartinTheFirst in about 12.3 seconds, someone on here is going to come up with a 637 page report with graphs and pictures to tell you that you are wrong. LOL ive never seen such fast research in my entire life. LOL and later on this week, I'm gonna be freezing my ass off hoping for just a touch of that heat they are promising.
