"Climate change is the most important issue of our time." You've probably heard this statement, or some variation of it, more times than you can count. But if somebody asked you to explain it, could you? When climate change comes up as a topic of conversation, what can you contribute? Instead of just nodding along, consider taking some time to really learn about climate change, why it's so important, and the range of solutions we have!
Why educate ourselves on climate change?
It can be terrifying, depressing, and even infuriating to face the truth: that human beings (especially the ultra-wealthy) are actively destroying the planet that our lives and economies depend on. When some powerful elites and greedy corporations seem to run the world, it can feel almost futile for the average person, or community, to try to fight back and stand up for what's right.
But, there's strength in numbers, and many people do care about others' safety, well-being, and access to clean water, air, food, and so on. And it's becoming more visible and tangible that these rights are endangered (in some areas of the world more than others) by the impacts of our rapidly changing climate, which only get worse the longer we ignore the issue.
So if we care about ensuring a livable future, we should be familiar with the fundamentals of what's happening to our climate and what we can do about it.
What's the simple definition of climate change?
Basically, climate change refers to significant shifts in Earth's long-term weather patterns (either warming up or cooling down). Our planet has experienced several ice ages, and the climate crisis we’re facing today has been caused by rapid warming. Here's a video explainer by Bill Nye. And here's a chart from NASA showing the rapid warming:
Global Warming Glossary: The Words You Need to Know
1. CLIMATE CHANGE
An accurate term used to describe the current phenomenon: “a long-term change in the earth's climate, especially a change due to an increase in the average atmospheric temperature” - Dictionary.com
2. GLOBAL WARMING
Another accurate term to describe climate change, but that's focused on the overall warming of the planet.
Merriam-Webster Dictionary defines global warming as "an increase in the earth's atmospheric and oceanic temperatures widely predicted to occur due to an increase in the greenhouse effect resulting especially from pollution”.
3. CLIMATE CRISIS/ GLOBAL WEIRDING/ CLIMATE DISRUPTION
Other terms that describe the ongoing phenomenon, but that more directly point to the unnatural-ness, urgency, and severity of the situation.
4. GREENHOUSE GASES
"Any of various gaseous compounds (such as carbon dioxide or methane) that absorb infrared radiation, trap heat in the atmosphere” - Merriam-Webster Dictionary
5. FOSSIL FUELS
“A fuel (such as coal, oil, or natural gas) formed in the earth from plant or animal remains” - Merriam-Webster Dictionary
Fossil fuels take millions of years to form. The process of burning them releases the greenhouse gases that contribute heavily to climate change and global warming.
6. CARBON SINK
Sometimes also described as a carbon drain, a carbon sink is something that pulls carbon out of the atmosphere. A great example is a forest, since trees breathe in carbon dioxide and breathe out oxygen. Other carbon sinks include oceans, soil, mangroves, and peatlands.
7. OCEAN ACIDIFICATION
“A reduction in the pH of the ocean over an extended period of time, caused primarily by uptake of carbon dioxide (CO2) from the atmosphere” - National Ocean Service
8. ENVIRONMENTAL JUSTICE
“The fair treatment and meaningful involvement of all people regardless of race, color, national origin, or income, with respect to the development, implementation, and enforcement of environmental laws, regulations, and policies” - the United States Environmental Protection Agency
When referring specifically to climate change, "environmental justice" can be called "climate justice". Many individuals and groups within the environmental and/or climate justice movement are very vocal about the fact that the people who're least responsible for climate change (primarily Black Indigenous People of Color and low-income people) are the first to feel its damaging effects. This unequal burden is an injustice that must be rectified in any and all ways we address climate change.
What are the main causes of climate change?
The vast majority of scientists agree: human activity is causing climate change, mainly by increasing carbon emissions, while decreasing carbon sinks.
Since the Industrial Revolution, human civilization has burnt fossil fuels at an ever-increasing rate, to meet our growing population's growing demands for energy. Burning this much fossil fuel emits copious amounts of greenhouse gases into Earth's atmosphere, where they get trapped and heat our planet.
Normally, Earth's carbon cycle naturally removes carbon at about the same rate that carbon is produced. But this carefully calibrated system is now taking in far more carbon dioxide and other greenhouse gases than it can handle. The carbon cycle cannot keep up with our high rate of emissions, and we don't do it any favors by simultaneously destroying the very environments that naturally absorb these gases (and actually store carbon).
Forests are increasingly getting cut down for other land uses, including industrial agriculture, which also severely degrades the soil, another key carbon sink. And at least one-third of our carbon emissions get absorbed by the oceans, making them more and more acidic — which means they're less and less able to absorb carbon dioxide and serve as a carbon sink.
More carbon in our atmosphere and our oceans means more warming, more extreme weather events, more sea-level rise, more mass extinction — the list goes on.
Solutions: A Brighter Future is Possible
Climate change is an enormous, multi-faceted challenge, so it's very easy to get overwhelmed and start to feel helpless. But we have to keep in mind: there are reasons to keep calm and carry on.
For one, we still have time (nine years now, to be exact; every year counts). For another, the majority of people in the US — the country with the most historical emissions — are concerned about climate change and agree we need to act.
There's no silver bullet or single cure-all for the climate crisis. Rather, we need a wide variety of bold solutions to come from every sector: from electricity, to buildings, to transportation, to industry, to agriculture, to education. Everything plays a role in decreasing emissions, increasing carbon sinks, and allowing our planet to thrive.
Most importantly, we must put equity and justice at the center of all solutions. What's the point of solving climate change if we don't make sure, in this new-and-improved world, everyone can lead a safe, healthy, dignified life? All Earthlings deserve the opportunity to participate in, and benefit from, the advancements that our modern society makes.
Obviously, the biggest corporate and institutional polluters have the most responsibility, and financial ability, to make the big changes that will clean up their messes and prevent climate catastrophe. But that does not mean the general public is off the hook or that our actions don't matter — no, quite the contrary.
While we push government and business to do better, we can also take steps to improve our own consumption habits and lifestyles that will reduce our personal carbon footprint. Both strategies are important for making change. And as we integrate more small-scale climate solutions into our own lives, we're rewarded with a sense of empowerment and hope that things can get better.
Of course, personal climate action does not always look like biking everywhere and eating plants all day every day; that's just not the reality most people live in (yet), and that's okay. The good news is, there are many different ways to be climate-positive — in fact, one of those ways is simply learning about all the solutions!
After reading climate books and watching climate documentaries, we can share all that we're learning with our friends, family, co-workers, etc. As climate scientist Katharine Hayhoe likes to say, talking to people about climate change is one of the most effective things we can do about it.

Bring Others Along for the Ride
Learning about climate change is a journey. All the dire information and warnings can be emotionally exhausting at times, so it helps to have other people by our side, to support us in the process of learning, as well as acting on our knowledge.
When it comes to something as important as climate change, don’t feel like you have to learn everything all at once, or all by yourself. The last thing we want to do is get burnt out. We can sustain our learning over the long term by making it a daily or weekly practice. And we'll often get more out of it if we invite our friends and/or family to learn with us and have critical discussions.
So, let's think: who in your life could you talk about climate change with, on a regular basis? Who might want to watch a climate documentary with you? If you're a bookworm, look up climate or environmental book clubs to become a part of. If you're a podcast junkie, send your latest favorite episode on climate change to your friends' group chat, and see what they think.
If you take one thing away from this post, let it be this: you are not alone in facing the truth of climate change. More and more Earthlings are awakening to the crisis, along with its many solutions, and there is a vast global community working to build a climate-positive future. And we're here to welcome you with open arms, whenever you're ready to join.
