Inside Climate News reports that new documents have added to the evidence in a climate deception case against ExxonMobil. The article places that development against a much older timeline, opening with the year the outlet suggests the world began waking up to climate change.
That year is 1988. In June of it, the NASA climatologist James Hansen testified to Congress that the climate was warming and would continue to do so as long as humans pumped fossil fuel pollution into the atmosphere. Inside Climate News uses that testimony as the anchor for its account of the case.
Only an excerpt of the article is available here, and it cuts off mid-sentence. The specific contents of the new documents, the court or venue involved, and any response from ExxonMobil are not described in the text provided, so the weight of the new material cannot be assessed from what is available.
