“False Alarm” By Bjorn Lomborg is a review of Lomberg's latest book.
Let us be clear here, Lomberg accepts climate change: "Lomborg is a 'lukewarmer'. He thinks global warming is real, man-made, and a serious problem, which can be and needs to be tackled." But he disagrees it's a crisis, disputes it's an existential risk.
Here's why in a nutshell:

The IPCC’s best estimate is that if no further action were taken to slow the warming, the increase by 2100 would be 7.2°F, or 4°C. Nordhaus’ model indicates that this level of warming would reduce global GDP by 2.9%. To be on the safe side, Nordhaus adds an extra 25% to each element of forecast damage, which takes the overall GDP reduction to 4%.
Between now and 2100, economists expect global GDP to increase by about 450%, so the forecast warming-derived damage would reduce this increase to 434%. This is clearly important, but not catastrophic. The IPCC itself says “for most economic sectors, the impact of climate change will be small relative to the impacts of other drivers” such as population growth, income growth, and so on. Nordhaus says that global warming “is not like a huge asteroid hurtling toward earth. It is instead a long-term chronic condition, like diabetes.”
