Many analyze and report valid, accurate, correct results.
The news media prints and exploits ONLY those "eco-extremist experts" who DO lie.
And the thousands of "ecologists" who blatantly exaggerate these lies.
Those "some" of course include the ones who run and control the IPCC. There are many good scientist who put out good data, but then that data is convoluted and spun by the IPCC.
