Yes, climate change is a complex, globally interrelated issue. But there are tangible ways you can make a change.

1. Your next car needs to be electric
Part of the problem is our current transport infrastructure, so electric cars need to be a big part of the picture.
Griffith says if you must, a plug-in hybrid will also do. If there isn’t an electric vehicle on the market right now that suits your needs, hold on to your current vehicle until there is one available that works for you.
He adds the idea of buying an electric car doesn’t have to be all doom and gloom. In fact, he says that their quiet engines and fun-to-drive nature is even something to be excited about.
“We might laugh at some of the things that Andrew Yang says, but he’s the closest to a visionary sometimes of the current Presidential candidates when he says, ‘you know what?’ There’s no regrets when you own an electric vehicle. It’s just a more fun car to drive’,” Griffith says.
2. Electrify your home 
That means no more furnaces burning natural gas, which is still a fossil fuel. Griffith says if your house is heated by natural gas, you will instead need to heat it with an electric heat pump.
Your gas range will need to be replaced by an induction stove top. Your water heater should be solar or electric heat-pump.
A secondary benefit of making these changes, beyond reducing greenhouse gas emissions, is that electrifying your home in this manner improves indoor air quality, which is a factor in many peoples’ respiratory problems.
3. Eat less meat
Griffith began looking at his and his family’s diet when he realised that it might be hypocritical for a climate change evangelist to not take a serious look at their own lifestyle. For Griffith, this has meant cutting meat right back to one meal with quality meat per week rather than eating crappy meat with every meal, and ditching his beloved imported wine.
The environmental consequences of what we eat are nuanced, and best calculated with a carbon calculator, but basically, researchers have found that the consumption of meat, or more specifically red meat, is the greatest contributor of greenhouse gas emissions from our diets.
4. Lobby your politicians 
And if not, agitate to help make sure the requisite legislation is put in place. A lot of legislation is just straight-up old, and was written in and for a time when we were a fossil fuel dependent economy.
Politically, this is not about “left” versus “right”, which in the context of climate change, is at this point a fairly stale and unhelpful metaphor. The political will and imagination for our 21st Century problems must transcend a binary that historically stems more from who sat where in the Legislative Assembly than anything else.
“No political party has yet proposed a vision comprehensive enough to get us there. So we need a movement from the people, we will need new political coalitions, and we need it all immediately. We need to work together,” Griffith says.
He argues that the old way of doing things is embedded in legislation and thinking everywhere: building codes that aren’t friendly to solar, electrical codes that artificially increase the cost of solar and home and vehicle electrification, net metering regulations, road rules, petrol taxes and speed limits, and tax incentives.
A cluster of tech nerds will make the electric cars, air conditioners and electric furnaces, solar power plants and bio-reactors of the future.
“For everyone else, the best place to engage is by making sure local regulations are compatible with solving climate change. We certainly cant deliver the change required on schedule if we are waiting for Town Hall to issue us the permits,” he says.
