The problem with climate change is not whether it exists but the solutions offered by the left to solve it. Bjorn Lomborg explains in Climate change activists are focused on all the wrong solutions.

As it is becoming obvious that political responses to global warming such as the Paris treaty are not working, environmentalists are urging us to consider the climate impact of our personal actions. Don’t eat meat, don’t drive a gasoline-powered car and don’t fly, they say. But these individual actions won’t make a substantial difference to our planet, and such demands divert attention away from the solutions that are needed.

...The Paris treaty cannot do much — just like the Rio and Kyoto pacts mostly failed before it — because this approach requires rich countries to promise future economic hardship to achieve very little.

...Solving climate change, in fact, requires getting China, India and all the other developing countries on board to cut emissions. But of course, their goal is to lift their populations out of poverty with cheap and reliable energy. How do we square that?

A carbon tax can play a limited but important role in factoring the costs of climate change into fossil-fuel use....

This, however, will not solve most of the climate challenge. We must look at how we solved past major challenges — through innovation....

Similarly, the climate challenge will not be solved by asking people to use less (and more expensive) green energy. Instead, we should dramatically ramp up spending on research and development into green energy.

Right now, despite all the rhetoric about the importance of global warming, we are not ramping up this spending. On the sidelines of the 2015 Paris climate summit, more than 20 world leaders made a promise to double green-energy research and development by 2020. But spending has only inched up from $16 billion in 2015 to $17 billion in 2018. This is a broken promise that matters.

After 30 years of pursuing the wrong solution to climate change, we need to change the script.
Solutions must, iow, be free-market ones.
