U.S. withdrawal from international climate bodies sidelines scientists when climate impacts are accelerating.

AGU remains engaged at UNFCCC COP, supports U.S. scientists in the next #IPCC assessment, & urges Congress to protect science funding.

Science belongs at the table.

Art x Climate is an integral part of the Fifth National Climate Assessment (NCA5), restored by Climate.us.
One of the featured artworks is β€œDrift Ice” by Deborah Pressman. Year and Medium: 2020, ink, oil sticks on paper
How to depict glaciers and ice floes? I form large pieces of paper into topographic representations of landscapes. The tactile features of the work change the perception of the image from flat representation to a semi-sculptural form. The polar regions are the most fragile and consequential for climate change and so far from population centers. Creating images that viewers can almost touch, that gives them a sense of the land, might help to foster shared responsibility for these fragile, vital areas.

Diurnal signal in XCO2 for the Park Falls (a) TCCON and (b) spatially co‐located OCO‐3 versus hourly bin shown in local time. While diurnal cycle is clear with wealth of ground-based TCCON data, satellite OCO-3 data are not yet sufficiently dense to quantify the climatological diurnal cycle

Summary of how N-required to define diurnal cycle varies with diurnal signal across TCCON sites for the diurnal rate of change, plotted as a function of the calculated monthly diurnal change. Observations are plotted in cool colors, and Carbon Tracker model CT2022 data are plotted in warm colors.

a) Diurnal changes in XCO2 calculated from the Park Falls TCCON across all calendar months and (b) the corresponding number of observations per hour required to detect a diurnal rate of change that excludes 0 ppm/hr within two standard deviations of the mean.

Ground-based data show that at least 10 independent observations per hour per month are required to robustly quantify the diurnal cycle. Figure shows standard deviation of bootstrapped diurnal drawdown at Park Falls for two representative months as a function of available number of samples N

Example of diurnal cycle calculation for the month of June at Park Falls from ground-based TCCON data. The diurnal cycle in total column carbon dioxide (XCO2) due to biological CO2 uptake during the day is less than 1 ppm even during the peak growing season

Annual cycle of column XCO2 detrended anomalies at Park Falls, WI. Speard of TCCON data (purple) on any given
day arises from interannual variability, synoptic variability, and diurnal fluxes. OCO‐3 XCO2 data (orange) coincident with Park Falls between 2019 and 2025 are

Observational Requirements for Quantifying the Diurnal Cycle of XCO2 From Space

Orbiting Carbon Observatory-3 (OCO-3) data are not yet sufficiently dense to quantify climatological diurnal cycle in column CO2

The diurnal signal in XCO2 for the Park Falls (a) TCCON and (b) spatially co‐located OCO‐3, calculated by detrending and deseasonalizing raw data, then calculating the hourly mean for all XCO2 acquired within the specified hourly bin shown in local time (LT). For TCCON, panel (c) shows that the hourly bins contain at least 100 XCO2 soundings, but for OCO‐3 (d), the number of observations is typically less than 10.

Greenland’s melting ice and landslide-prone fjords make the oil and minerals Trump is eyeing dangerous to extract
