The weakness in the case against Exxon on 'climate change'

Bloomberg:

Exxon Mobil Corp. was sued by Massachusetts for allegedly hiding its early knowledge of climate change from the public and misleading investors about the future financial impact of global warming, two days after a trial started on similar claims in New York.

The 205-page complaint, filed Thursday in state court in Boston, goes further than the suit filed a year ago in New York by alleging Exxon misled the general public as well as shareholders by concealing the looming crisis.

Massachusetts Attorney General Maura Healey, who’s seeking unspecified monetary damages, says Exxon predicted high levels of carbon dioxide in the atmosphere as early as 1982 and effectively hid the information.

According to the complaint, Irving, Texas-based Exxon went so far as to disregard the findings of one of its own scientists, who decades ago correctly predicted the amount of CO2 in the atmosphere in 2019 and said that climate change would become “catastrophic.”

Healey, who’s been investigating Exxon since 2016, claims Exxon’s actions violated the Massachusetts Consumer Protection Act.

One of the reasons the predictions of a climate catastrophe have failed to be realized is that scientists have overestimated the impact of CO2 for decades.  Their predictions of ice-free polar areas and New York and other major cities being underwater have never been realized.  In fact, these prior predictions are now reason to doubt the theory of climate change.  At any rate their failure to accurate project, the impact of increased CO2 is evidence that they relied on invalid assumptions in making those predictions.
