Explaining the key scientific ideas, technologies, and policies relevant to the global climate crisis.

Recent Podcast

A growing population, groundwater depletion, poor water infrastructure, overuse and water waste threaten our global freshwater supply.

Throw climate change into the mix, and the water crisis is exacerbated, as precipitation becomes more variable and temperatures reach extremes.

The water crisis, like the climate crisis, is projected to get worse, but there are solutions both corporations and governments can adopt to mitigate and prepare.

Climate Now spoke with Will Sarni, Founder and CEO of Water Foundry and a global thought leader on water challenges, to learn about the strategies and technologies available to assuage the water crisis.

What if we could remove the carbon we have emitted into the atmosphere? Can we capture our CO2 emissions before they are even released?

In Part I of our two-part Carbon Capture and Storage series, our host Dr. Ozak Esu and two internationally-recognized CCS experts, Dr. Julio Friedmann and Dr. Howard Herzog, explain the science behind carbon capture, how much it costs, and who is leading the industry.

Most climate models in use today are based upon large-scale, well-understood physical relationships that drive global temperature and precipitation trends.

But the effects of complicated interactions that occur on smaller scales, which may still be significant, are harder to capture in these models.

That is why Dr. Laure Zanna of New York University and her colleagues are employing machine learning techniques, which can “learn” the effects of these interactions without explicitly solving the physics, to improve climate modeling.  Climate Now spoke with Dr. Zanna to learn more.

Planting trees has become a bit of a cliché in the fight against climate change, with ubiquitous photos of presidents and CEOs planting a tree to show they’re serious about climate. But, how much impact on atmospheric carbon dioxide can tree planting really have?

In the first episode of a series on carbon dioxide removal techniques, we explore the potential and the limitations of using forests to draw anthropogenic carbon emissions out of the atmosphere.

What does it take to turn an idea that could help fight climate change into a self-sustaining business? We often hear the glamorous stories of startups that have made it, but little about the struggles, the learning, and the luck required to get there.

Pol Knops, Founder and Chief Technology Officer of Green Minerals, joined Climate Now to share his ongoing journey to design, develop and market a process that transforms carbon dioxide emissions into a useful product.

Green Minerals speeds up the natural process of mineralization, in which CO2 chemically reacts with iron, magnesium or calcium-rich minerals to form a new mineral, permanently trapping the CO2.

The Green Minerals mineralization process uses olivine to react with captured CO2 to create feedstocks for the concrete and paper industries.
