Higher temperatures won't hurt the U.S. economy, they might argue ...

I don't get it. The article said that climate change would hurt poor countries. Isn't the U.S. well on its way to being one?

It does not have to be true, but it will be true to the extent that the rich countries allow it.

"In rich countries, changes in temperature had no discernible effect on growth."

So climate change does not impact the growth rate of developed economies. Wow. Again, the net impact for developed economies is zero.

Perhaps we overestimated the economic impact of climate change all along?

But since the US produces much of the world's food, it would seem at least that the methodology is flawed.

I am a development economist and I looked over the paper you cited; I think it falls squarely into the category of research that makes a great headline but doesn't actually have much to it. Basically, they have run a regression where they leave out all of the things we typically think might be important for economic growth - investment, technology, education, trade, etc. and then see a significant negative effect of temperature in poor countries. They then argue that temperature works through the things they have left out, but the problem is they left them out, which has most likely biased the temperature effect. "Climate change will hurt the world's poor" certainly makes a good headline, and it is probably true in many ways, but this paper isn't really adding any believable evidence to that debate.

What will really keep the World's poor in their place is telling them that they must forego power plants and modernity. The luddite romanticism of the global warming alarmists would have us all to return to the horror of the stone age.

I'm definitely more productive when I'm cooler.

if the economy in the united states has good prospects but there is no actual terra firma called the united stataes because it's all been decimated by monster hurricanes and other greenhouse gas effects what will it matter? when does the disconnect between the economy and the actual world end? it's like that silly drawing that gore shows in an inconvenient truth. gold bars in one side of the balance and the earth in the other. someway somehow the truth has to sink into the heads of even the most thick materialist. money don't mean a thing without a planet to spend it on.
