Remarkable changes to carbon emission budgets in the IPCC Special Report on Global Warming of 1.5C

by Nic Lewis A close reading of Chapters 1 and 2 of the IPCC Special Report on Global Warming of 1.5°C (SR15) reveals some interesting changes from the IPCC 5th Assessment Report (AR5), and other science-relevant statements. This article highlights … Continue reading

Early 20th century global warming

by Judith Curry A careful look at the early 20th century global warming, which is almost as large as the warming since 1950.  Until we can explain the early 20th century warming, I have little confidence IPCC and NCA4 attribution … Continue reading

Rebelling against the Extinction Rebellion

by Larry Kummer The Extinction Rebellion and the Green New Deal arouse fears of extinction for other species, and humanity. Only the complicit silence of climate scientists makes this possible. Compare the alarmists’ claims with what scientists said in the … Continue reading

Warming patterns are unlikely to explain low historical estimates of climate sensitivity

By Nic Lewis A critique of of a new paper by Andrews  et al., Accounting for changing temperature patterns increases historical estimates of climate sensitivity.

Hurricanes & climate change: landfalls

by Judith Curry Part III: is there any signal of global warming in landfalling hurricanes and their impacts?

Why Dessler et al.’s critique of energy-budget climate sensitivity estimation is mistaken

By Nic Lewis Plain language summary A new paper by Andrew Dessler et al. claims, based on 100 simulations of the historical period (1850 to date) by the MPI‑ESM1.1 climate model, that estimates of climate sensitivity using the energy-budget method … Continue reading

Impact of recent forcing and ocean heat uptake data on estimates of climate sensitivity

by Nic Lewis We have now updated the LC15 paper with a new paper that has been published in the Journal of Climate “The impact of recent forcing and ocean heat uptake data on estimates of climate sensitivity“.  The paper … Continue reading

Escape from model land

by Judith Curry “Letting go of the phantastic mathematical objects and achievables of model- land can lead to more relevant information on the real world and thus better-informed decision- making.” – Erica Thompson and Lenny Smith

Climate sensitivity to cumulative carbon emissions

By Nic Lewis An observational estimate of transient (multidecadal) warming relative to cumulative CO2 emissions is little over half that per IPCC AR5 projections. AR5 claims that CO2-caused warming would be undiminished for 1000 years after emissions cease, but observations … Continue reading
