Let’s be honest: telling your parents they might be wrong about something has never been easy. Now, throw in politics, Thanksgiving dinner and climate change? That’s a recipe for disaster — and indigestion.

But here’s the thing — if you approach the conversation in the right way, you can actually communicate some pretty challenging information without it spiraling into a shouting match. Here’s how to talk to your parents, or anyone on the other side of the issue, about climate change.

First, ask their opinions and really listen. Showing respect for their position opens the pathway for them to reciprocate.

Don’t be defensive. Instead, look for facts everyone can agree on. Yes, the climate has always changed; we’ve had ice ages and warming periods. What’s different now is that it’s happening at an unprecedented speed — 10 times faster than normal climate swings — and human actions are driving it. Unlike hunter-gatherers who could chase migrating herds when things got rough, there are nearly 8 billion of us now (soon to be 10) living in a complicated and interconnected global economy. We can’t just pack up and follow the food and water resources as they react to a changing climate.

We can also agree that fossil fuels have been extraordinary friends to us. Before them, life was nasty, brutish and short. They gave us modern medicine, global trade and Sunday football. But now financial and insurance experts — and all of the major scientific institutions — warn that burning them is changing the composition of our atmosphere and will trigger disastrous changes in our natural systems.

These changes will harm our economy and way of life and reverse that success story. Our new story will be a shrinking GDP and threats to our security and quality of life, especially for our children and grandchildren.

Instead of diving into climate jargon, invite your parents to evaluate it the way they’d evaluate any risk in life.

How likely is it? We can see it with our own eyes in our communities and in the news: Our summers are hotter and extend longer, we are more exposed to wildfires and wildfire smoke, our rain patterns are changing (causing both more torrential floods and extreme dry periods), and our sea level is rising rapidly (causing sunny day flooding and damage up and down our coastlines).

What are the consequences if the worst comes to pass? Credible projections predict temperatures and humidity levels will soon become too high for even young, healthy humans to safely be outside in some parts of the world. Crop yields are expected to plummet as heat thresholds are crossed and water systems are disrupted. Coral reefs, the nurseries to 25% of sea life, will die. Many cities and shoreline infrastructure will be under water. Conflicts will arise over dwindling natural resources and increased migration pressures. These predictions aren’t from environmentalists — they are from military, scientific and economic experts.

How hard is it to avoid? We know that acting now will save us a lot of money and pain in the future. Waiting only makes things much worse.

We also have a plethora of solutions and newer technologies, like next-generation nuclear and geothermal and carbon capture, that most people favor. And numbers don’t lie — renewable energy has boosted jobs and grid security, particularly in conservative areas (80% of clean energy jobs are in areas that voted for President Donald Trump) and costs less than fossil fuel power sources.

Don’t lecture or harangue. Lean into the values that conservatives hold dear: prudence, stewardship, self-reliance and responsibility. Remind them that the longer we wait to act, the bigger the burden on future generations.

Point out that Republicans like George W. Bush, Kevin McCarthy, James Baker and George Shultz have taken climate change seriously. Share that young conservatives care about this issue too. Bring up that there are “conservative” solutions like protecting land, nuclear and carbon capture, or a fee on carbon.

Always end with optimism, not blame, guilt or defeatism. It’s not too late. We can adapt and mitigate. We can, and do, innovate. We can act in ways that make the economy stronger, our communities healthier and the world more stable. Use this to appeal to their hearts while talking to their heads.

And isn’t that what our parents always taught us? Take responsibility. Clean up your mess. Leave things better than you found them.
