Our warming planet isn’t just a threat to future generations; it’s a threat to us right now. If we don’t mitigate it, the continued rise in global temperature will have ripple effects throughout ecosystems and communities. In this episode of Crash Course Climate and Energy, we’ll look at how climate change has already affected our planet, and what the future might hold.

Great video! There’s this terrible line we have to walk between making sure the most vulnerable aren’t taken out by economic stagnation due to over aggressive climate policies and making sure that they don’t get taken out by a lack of action to do anything to stop climate change. I think like with anything, we’re learning as we go and we’ll get better at crafting climate policy that straddles this line well and be something that all of us can agree to. I really hope we limit climate change to 1.5 degrees, but I’m not sure it’s possible. Even if we fail to limit it to 2 degrees it cannot be overstated that we still must try. We need to take all of the problems seriously and we need all the ideas we can get our hands on to try and solve this. I think what I’m trying to say is not to despair. Despair is the same thing as giving up, and we need to keep trying even when the odds are very much stacked against us.
They keep updating the date for climate doom cuz they keep overselling. Notice how you can’t find “An Inconvenient Truth” on any streaming apps these days?
its like the trolly problem but we are the ones tied to the tracks
Really hoping this isn't the end of the series. Too much left that's hardly been touched.
These videos are incredibly educational and important, more people need to be aware than ever. But It’s hard to shake the hopelessness and helplessness these messages keep reminding of us that’s it’s not changing. Like children being warned about their parents irresponsible behavior, what can we do if it hasn’t been changed yet. The ones who care don’t hold the power.
Climate change is real, how the governments are dealing with it and pressuring people to accept false narratives us a SCAM.
Eh humanity had a good run. I mean Too bad the worst people have the most power, but I'm pretty sure if we were gonna fix things we'd have managed it by now. Just make sure your Doomsday kit has a comfy folding chair and a bottle of your favorite liquor.
Well, me paying more taxes won't solve it
as a citizen of the southern interior of BC Canada, yes climate change is real and yes it has already destroyed one of our cities.
Great episode M! Sadly, many in our world will not care about the effects of climate change unless it affects them directly. The last two COPs just show how wealthy countries care so little about the smaller and more vulnerable countries that are affected the most by climate change. The number of climate refugees will continue to increase, as well as internal displacement of people within their own country. Climate change is real and if we don't do something to slow the effects, many countries in the Caribbean and Pacific, and other low-lying countries in the world will disappear. People will have no choice to leave their homes because it will be virtually uninhabitable, like you mentioned. It's time to stop talking and start doing when it comes to climate change. Let's try setting up the loss and damages fund that was advanced at the 2022 COP in Egypt. Let there be greater access to concessionary financing for smaller and poorer nations, so they will not have to incur serious debt just to try to help their citizens. I see it happening virtually every hurricane season in my country St. Vincent 🇻🇨. Keep up the great work with the videos.
They asked the same question after the last ice age.
warming here in texas is hyper noticeable with significantly rarer winter precipitation outside of the destabilized polar vortex making it here
Love this series! Can't wait for your episode on the Pentagon, the single largest source of pollution on the planet!
Actually, every 0.1 degree saves lives and helps (as scientists have calculated and shown in recent years). So it’s worth keeping up the fight, even if we don’t manage the 1.5 degree goal.
Unfortunately, the issue of climate change is partisan (even though it shouldn't be), and with one party openly denying what is right in front of their face, there is no way we can pass laws to keep it under control fast enough (if at all).
Thanks for this critical and very well done series. You really packed a lot of info into a very succinct episode – very impressive.
You alluded to the close inter-connected links between ecological, environmental, socio-cultural, political & economic systems. It should be stressed that ALL human systems occur within the ecological system – and not the other way round. ALL human systems rely heavily on ecological systems, processes, services & goods. Saving the Earth is NOT a "radical leftist tree-hugger hippy" thing, it's a "saving humankind and everything we hold dear" thing!
While there are many many many hurdles, global efforts are occurring behind the scenes to try and restore the climate, natural systems, biodiversity AND human welfare – ALL AT THE SAME TIME. Such international efforts includes (among MANY international agreements)
– the 2030 Agenda on Sustainable Development to achieve healthy ecological, socio-cultural & economic systems (for all)
– Habitat III and the New Urban Agenda (it's estimated that around 80% of humans will live in cities & towns by 2050'ish – so making cities work for everyone is absolutely critical!)
– Sendai Framework for Hazard Risk Reduction to make the world a safer place
– UNCAC to reduce incidence of international crime & corruption
– Beijing Declaration on gender equality
Think global, act local! While dirty corporations & individuals try to pass the responsibility for climate restoration onto individuals (don't fall for it), individuals can make a contribution via citizenship (make a difference in your community and your country), career (make a different where you work) and as a consumer (be mindful of the products you buy and the companies you support with your buying power).
Individuals, businesses & governments at all levels must work together to create communities, cities, regions & countries that are sustainable, green, integrated, inclusive, safe, healthy, beautiful, gender-sensitive, child-friendly, resilient and climate-ready. Tactical urbanism is a way that communities can implement local projects that benefits everybody. Other great new strategies for community development includes "new urbanism" and "strong towns".
Vested interests seek to maintain the status quo and horde wealth & privilege for the minority. Remaining quiet is no longer an option for the majority of us – get involved in local community groups to find solutions to local challenges. Many issues we face are global ones – whatever they are – so chances are good someone somewhere has figured out and implemented a solution. Where there's a will, there's a way.
You can't negotiate with nature – it sets limits & describes consequences. The Earth is telling us that limits are being reached and we will not like the consequences unless we do things differently. So it's time for all of us to do our part to make the world a more equitable place. It's time to reflect on what's really important (family & friendships and community – i.e. healthy social relationships) and ditch the things that we're actually much better off without. It's also not just about us but the generations that come after us. Our responsibility is not just with the present, but to the future as well.
9:50 The effect of higher sea levels will also worsen the intrusion of saltwater into freshwater reserves near coastal communities, leading to a reduction in available ground water and loss of soil fertility.
We need more people, so we can have more scientists and engineers to work on solutions and adaptations. And we need less unscientific pseudo-religious "the world is ending and judgment day is coming" messaging from scientists and politicians on the issues.
Another climate video dancing around and refusing to seriously engage with the radical political upheaval absolutely necessary to avoid anything but the worse case scenario, capitalism based systems will continue to prioritise for short term hyper profits over tackling environmental concerns and producing for needs rather than accumulation.
See Willow project. We are very very unlikely to stop at 1.5, we will be immensely lucky if we can stop at 2. I want to see a contrast of 2 vs. 3 C – where we are headed currently and how much we can still avoid in that scenario.

As above so below
What you reap is what you sow
What you give is returned threefold
As above so below
sadly….we already lost the battle for 2 degrees…like 5 years ago. if not even earlier..
我要跟着你学英语
I HATE people who dont care about their climate change because they think they won't live that long
🤐🤔🤕🤢
You know, what about a molecular biology series?
Thank you , amazing lecture ❤
One things for certain, in almost every way the people who say back in the day was better are absolutely wrong. Back in the day even managed to screw up the environment
I'm actually feeling the effects of climate change as an adult. When I was a kid, we had discernable seasons and a lot of snow. Now, not so much.
Round up the rich and send them to the Amish and sieze the means of production
My company has pledged to go carbon natural by 2050. 20 years too late but hey, better late than never.
Please make new and updated seires on psychology.
Unrelated, but at first, I thought she might have been the woman who played Andrea on the Walking Dead like 10 years ago.
80s we already KNEW ozone layer had a hole… gov't policy ECONOMY #1 put off green-planning, EVs, climate-proof home re(in)novations tax credits etc. I had pet fish — learnt so much from her — sea life are VERY sensitive to 1C change! heat wave in BC Canada last summer: granny fainted from a heat stroke! worsening flooding in BC, forest fires in different countries… and some people investing in space travel (colonize planet Pandora?! 🤔) that's just escapism 😢 where's the humanity?! Some island 🏝️ countries are gonna disappear due to sea level rise 😢
anyone saw the 1hr documentary made by BBC Earth about the change that happened during 2020 lockdown: CO2 dropped, beach suddenly became empty — penguins were able to dive in get food several times daily to feed their babies (normally they avoid humans and wait til sunset to feed ONCE daily)… anyone saw the movie "Snowpiercer" post-apocalyptic wintery world where remaining people live in a huge train — of course 1st class cabins eat and live normally, and everyone else have to eat jello meals (made of bug powder!) 😱
I was under the impression 1.5 degrees was out of the game.. looks more like we're gonna go towards a + 4° C with the current flow of things. but hey, I'm just a random guy on the internet, what do I know.
This couldn't have come at a more perfect time. Working towards my BS in Environmental Sciences and my current course in climate change requires us to examine an article or video discussing what effects climate change will have over the next century. I'm so thankful to be able to use Crash Course for this, as it is so easy to digest and have confidence in the source material <3
Meh….what about China and South America, where the govts don’t care.
Too many people I know think climate change is a hoax.
