We have only rarely linked to stories featuring or mentioning Mr. Gates.

This is not because we do not value his opinions; we think he is the smart money on multiple fronts. Climate change is one of them.

Even if we consider McKibben the more reliable scribe, and even if we give Malmo his due, this is still smart money territory:

The state of the energy transition

My annual memo about the journey to zero emissions.

When I first started learning about climate change 15 years ago, I came to three conclusions. First, avoiding a climate disaster would be the hardest challenge people had ever faced. Second, the only way to do it was to invest aggressively in clean-energy innovation and deployment. And third, we needed to get going.

Since then, an influx of private and public investment has accelerated innovation faster than I dared hope. This progress makes me optimistic about the future.

But I am also realistic about the present. The world still needs to reduce annual greenhouse gas emissions from 51 billion tons to zero, but global emissions continue to increase every year. If you follow the annual IPCC reports, you’ve watched as the scenarios for limiting the global temperature rise to 1.5 or even 2 degrees Celsius become increasingly remote. And some of the clean technologies we need are still very far from becoming practical, cost-effective solutions we can deploy at scale.

In the past decade, we finally got going. Over the next three, we need to go much further, much faster. I still believe we can avoid a climate disaster—if we devote the next generation to mobilizing the largest crisis response in human history…
