Careful, that’s not quite accurate.
The news comes from a climate denialist website and should be taken with extreme caution: pseudoscience is often like a wolf in sheep’s clothing – it mimics the language and form of science, but hides preconceived theories lacking methodological rigor.
The conference in question did take place, but it was organized by an organization known for its climate denialist views and in no way represents a body recognized by the international scientific community.
In short, there has never been a genuine scientific consensus on this alleged “declaration of the end of the emergency”: it is a headline deliberately crafted to mislead the public.
