Simple answer - No. Based on Paris Agreement, if the Country has enacted local laws for the companies to adhere to, they can be prosecuted.

Dear Kenneth, you are in disagreement with 97% of knowledgeable scientists.

@Kenneth, You and I have already locked horns (few years ago). Your stance and your background are suspect. Your task is just to try to spread unfounded doubts and confusion - i.e. muddy the water - in order to forestall or dismantle efforts to reduce CO2 emissions.

One would have to find an organization that would be willing and able to organize and follow through on such a class action suit. There are several dependencies of the United Nations that might be interested, including the UNDP and the one on climate change. Most probably pro bono lawyers would have to be found so as not to make it an overly expensive endeavor. Since much of climate change adversely affects people in many, if not all, countries, it could perhaps be a case for the International Criminal Court (including crimes against nature and crimes against humanity)

Some examples of the harm being done, to name a few are: the drought and fires in the western USA; the migrations of former farmers in many parts of the world who cannot sustain themselves because of extreme weather disruptions; the increased frequency and severity of hurricanes/typhoons. The ultimate cause of these catastrophes is the excessive warming of the polar regions which, in turn, causes the breakdown of the polar vortices.

@Kenneth, You are irresponsibly, ignoring the vast findings of the vast majority of expert scientists. You and other deniers, start with an agenda, then try to find facts, that when taken out of context, seem to support your agenda. In chemistry, this used to be called "dry labbing." There is too much at stake to not call out such travesties.

Just as I expected (judging by your present and past stance on this topic:

Manhattan Institute for Policy Research - SourceWatch

The Manhattan Institute (MI) is a right-wing 501(c)(3) non-profit think tank founded in .... Jane Mayer documents this in her book Dark Money when she writes, ...

It is very well known that the fossil fuel and related industries and governments have trillions of dollars invested in fossil fuels, and they see pushback by scientists and the public who want curbs on CO2 emissions as a threat to be eliminated, by any means. The profit motive in this case, like the case of linking tobacco to cancer, leads companies to try to conceal, misinform , propagandize, etc. to continue their dirty business. Read Jane Mayer's well-documented book titled "Dirty Money."

Despite any views expressed above...rather than

(1) wildly guessing what might happen in climate change lawsuits by (2) asserting some assumption about what one believes to be “the facts” about the existence of climate change;

one should instead ACTUALLY CONSULT REAL legal case outcomes (i.e., do some actual research), since there have actually made ruling about what kinds of evidence that will/has been accepted/rejected in court cases.

FACT: There have been and currently are a number of on-going lawsuits endeavoring to recoup compensation for climate change related damage. (1) The UN and Columbia Law School estimate that there are currently about 900 on going climate change lawsuits in 24 countries (The Status of Climate Change Litigation: A Global Review (United Nations Environment Programme and Columbia University Sabin Center for Climate Change Law, 2017); (2) On US suits alone, see more below.

FACT: There are many examples of these suits, and these are only a few recent cases:

FACT: One can expect to see shareholders of oil company stock as well as the attorney generals of various states sue those companies for fraud related to possible Security exchange Commission (SEC) violations (e.,g NY and Massachusetts have already filed such suits). These kinds of suits have been used successfully against tobacco companies, and involve assessing claims relating public disinformation campaigns to laws related to knowingly making false public statements (which can also have bearing in SEC cases related to efforts to manipulate stock prices).

LEGAL INFORMATION/BACKGROUND: Scholars have discussed the legal basis of such suits: https://www.sciencedirect.com/science/article/pii/S1364032115012770

OUTCOMES: A recent study in NATURE has analyzed the outcomes of all known lawsuits associated with climate change (N = 873) filed in the US from 1990-2016 (https://www.nature.com/articles/s41558-018-0240-8).
