Intergovernmental Panel on Climate Change (IPCC) 2021 report states “It is unequivocal that human influence has warmed the atmosphere, ocean and land. Widespread and rapid changes in the atmosphere, ocean, cryosphere and biosphere have occurred.
Each of the last four decades has been successively warmer than any decade that preceded it since 1850. Global surface temperature in the first two decades of the 21st century (2001-2020) was 0.99 [0.84- 1.10] °C higher than 1850-19009.
A recent paper assesses whether ExxonMobil Corporation has in the past misled the general public
about climate change.
They examined 187 climate change communications from ExxonMobil, including rereviewed and non-peer-reviewed publications, from internal company documents.
“Our assessment of ExxonMobil’s
peer-reviewed publications and the role of its scientists supports the conclusion that the company did not ‘suppress’ climate science— indeed, it contributed to it.
However, on the question of whether ExxonMobil misled nonscienti\c audiences about climate science, our analysis supports the conclusion that it did. This conclusion is based on three factors: discrepancies in AGW communications between
document categories; imbalance
in impact of different document categories; and factual malpresentations in some advertorials.” ( PDF)
