Neither of those are factually accurate statements; they pair a claim to fact in the first half with a policy proposal in the second half. "We should/should not do something about this" is not a statement of fact, it's a value proposition. So if a media outlet is consistently pushing the same value proposition (namely, that we should expend considerable effort to counteract climate change), then it's biased, regardless of the factual accuracy of what they report.
