Looking at the quoted article, it looks like the tired old "methane bubbles come all at once" argument which is a distortion of the actual science around this.
Climate change is real and a huge problem that we can and need to solve. Stop feeding inaction and disdain for real science by promoting cranks sites like these.
EDIT: Looks like this site has been reviewed along with McPherson before:
