The benefits of not meeting Paris Accord emissions-reduction targets outweigh the costs associated even with worst-case-scenario global warming throughout the 21st century. A new comprehensive analysis (Tol, 2023) weighs the cost-benefit of meeting Paris Accord emission policy targets to keep global warming in check, or under 2°C. The analysis reveals that even in the best […]

Comprehensive data analysis shows relative sea levels were anywhere from 1 to 7 meters (~3.9 m) higher than present throughout the Mid-Holocene at 15 of 16 assessed sites across Southeast Asia. A new study (Li et al., 2023) compiles highstand records from sites spanning Thailand, Vietnam, Singapore, Malaysia, Borneo, Sunda Shelf, Makassar Strait…and indicates that […]

“…the rate of change in CO2 concentration is controlled, not by emissions, but by the global temperature” – Emrén, 2023 A new study published in the International Journal of Global Warming once again questions the popular narrative that says humans can control the temperatures of the ocean and melt the polar ice sheets by engaging […]

“…by about 10 kyr ago, regional MST values consistently approached or exceeded today’s value of about 23°C” – Baxter et al., 2023 According to a new temperature reconstruction published in Nature, the Horn of Africa and “global tropics as a whole” were “1.6°C warmer than today” throughout the Early and Middle Holocene. This is “consistent […]

…when using the same assumption-based methodology to arrive at the conclusion only 0.5% of scientific papers reject AGW. In a new study, six scientists (Dentelski et al., 2023) effectively eviscerate a methodologically flawed 2021 study (Lynas et al.) that claims 99.53% of 3,000 scientific papers examined (by subjectively classifying papers based only on what is […]

Variations in the greenhouse effect are predominantly modulated by water vapor and cloud cover. CO2’s role in the greenhouse effect is so minor it cannot be discerned. For decades scientists have reported that a CO2 concentration of about 300 ppm can only increase the downwelling longwave radiation (DLWR), or greenhouse effect, by about 1.5 W/m² […]

Analysis of CO2 residence times suggest 65% to 96.5% of the CO2 concentration increase since 1958 is natural. According to a new study, the claim that increases in atmospheric CO2 are driven exclusively by humans relies on a made-up, disparate accounting model, with the residence time for natural emissions 3 to 4 years (which is […]

Millennial-scale Arctic sea ice reconstructions do not corroborate alarmist claims of unprecedented sea ice losses in modern times. Using sea ice biomarker proxy (IP25), scientists (Kolling et al., 2023) have determined that the sea ice extent in the Labrador Sea was nearly absent throughout the year (close to 0.0 μg/gTOC) for much of the last […]

The timing of the dramatic Antarctic sea ice decline during the last deglaciation suggests solar forcing and sea ice retreat “instigated” century-scale climate warming and atmospheric CO2 change. This would appear to challenge the perception CO2 plays a causal role in glacial-interglacial sea ice and climate changes. From ~21,000 to 19,500 years ago, when CO2 […]

Yet another region of the world fails to cooperate with “global” warming instructions. New research (Zhang et al., 2023) finds the sea ice extent has undergone an overall increasing trend from 2005-2021 in the Sea of Japan, Yellow Sea, and Bohai Sea. “Over the past 17 years, the maximum sea ice extent in the marginal […]

IPCC models rooted in assumptions that we humans can and do control the Atlantic Ocean’s circulation with our daily-activity CO2 emissions have been wrong since the mid-1980s. Why should we still believe in them? The latest IPCC report continues to say it is “very likely” the Atlantic Meridional Ocean Circulation (AMOC), a fundamental climate parameter, […]

Significant 21st century cooling in the Central Pacific, Eastern Pacific, and nearly all of Antarctica “implies substantial uncertainties in future temperature projections of CMIP6 models.” – Zhang et al., 2023 New research indicates West Antarctica’s mean annual surface temperatures cooled by more than -1.8°C (-0.93°C per decade) from 1999-2018. In spring, the West Antarctic Ice […]
