We’ve been worried for good reason before 

It’s worth keeping in mind that climate change is not the first time smart people thought humans were doomed by our own successes or failures. Robert Malthus theorized at the end of the 18th century that projected human fertility would certainly outpace agricultural production. Just a century and a half later, about half of all Americans expected a nuclear war, and the number jumped to as high as 80 percent expecting the next war to be nuclear. Yes, global hunger and nuclear threats still exist, but our results have outperformed the worst of those dire projections.

We are worried for good reason today 

Today changing climate conditions have grabbed the headlines. The world’s climate is changing at a rate faster than we can model effectively, though our best modeling suggests significant, coordinated, global efforts are necessary to reverse current trends. While there’s still lots to learn, the consensus is that we are approaching a global temperature barrier across which we may not be able to quickly return. These conclusions are worrisome.

How did we get here?

Our reliance on hydrocarbons is at the heart of our climate challenge. If combusting them is so damaging, why do we keep doing it? We know enough about our human cognitive biases to say that humans tend to “live in the moment” when it comes to decision making. Nobel Prize-winning economic research suggests we choose behaviors that reward us today rather than those with longer term payoffs. Also, changing behaviors around hydrocarbons is hard. Crude oil, natural gas and coal have played a central role in the reduction of human suffering over time, helping to lift entire populations out of poverty, providing the power for our modern lives and even supplying instrumental materials for clothes and packaging. It’s hard to stop relying on a resource so plentiful, versatile and reliable.

How do we get out of here?

Technological advances in the future may help us address climate in new and unexpected ways. If we do nothing and hope for the best, what’s the alternative? We can take confidence that we’ve addressed difficult problems before. We can also take confidence that advancements like nuclear, solar, geothermal and wind power are already supplementing our primary reliance on hydrocarbons.

The path forward will be extending the utility of these existing alternatives and identifying new technologies. We need to reduce emissions and to withdraw greenhouse gasses (GHGs) that have already been emitted. The nascent energy transition will continue to be funded by venture capitalists, government spending/incentives and private philanthropy. Larger funding sources will come from private equity and public markets, as successful technologies compete for more traditional sources of capital.

Climate Tech will be a large piece of the climate puzzle

My biases are likely clear: the same global capitalism that brought about our complicated modern world, with its apparent abundance and related climate consequences, has the best chance to save us. Early stage climate tech funding is increasing, even if it’s still too small. It has been observed that climate tech startups receiving funding today fail to track solutions for industries in proportion to their related production of GHGs. For instance, the agriculture and food sector creates about 18 percent of global GHGs, while climate tech companies seeking to address that sector receive about 9 percent of climate tech funding. These misalignments aside, the trendlines are in the right direction.

What can you do?

From a psychological perspective, healthy coping means making small decisions that address your fears, even if you can’t eliminate the root causes. Where does that leave you?

Be a voice for reasonable change. Make changes in your behavior where and when you can. Also, take comfort when you see existing industries adopting meaningful sustainable practices at faster rates. Support the companies you believe are part of the solution.

We are already seeing a burgeoning climate tech industry across the globe and here at home. With concerted efforts like the Ion and Greentown Labs, the Houston climate tech sector is helping to lead the charge. In what was even recently an unthinkable reality, the United States has taken a leadership role. Tellingly, we are not leading necessarily by setting targets, but instead by funding young startups and new infrastructure like the hydrogen hubs. We don’t know when or where the next Thomas Edison will emerge to shine a new light in a dark world. However, I do suspect that that woman or man is alive today, and it’s our job to keep building a world worth that person saving.
