Actually, there were news stories in the US as well, including the scientific newsletters. It is true that a few of the thousands of scientists participating in the IPCC were sloppy in their methods. Shame on them. Still, their errors do not overthrow the fundamental science. There are dishonest or sloppy people in every profession but it does not mean that everything coming from that profession is false. I bet there are even people writing on climate change in this Forum who can't even describe the Planck-Boltzmann theory, or do a thermodynamic calculation, or explain the infrared absorption properties of carbon dioxide. But they still run off at the mouth.
