Is Global Warming a REAL Problem? (Ice Ages, Milankovitch Cycles and More)
643In this intriguing video, we will bravely tackle the topic of global warming. Now, I understand that this subject can be quite controversial, but we're not afraid to dive into the depths of it. So, let's get started!
Imagine you pick up a newspaper and all the headlines scream about the rising temperature around the world. It's a big concern, especially if they don’t make it clear what exactly is going on. Well, in this video, we're going to see what science has to say about it, and why we should care. I’ll make sure to explain everything in the simplest way possible. But brace yourself, because what you're about to learn might not be what you want to hear.
Here on this channel, we believe in the power of science. It's like a crystal ball, helping us predict the future and understand the past. We rely on it for videos about the vast solar system, the incredible Voyager probes, and even the mysterious atmospheres of faraway exoplanets. And guess what? Science plays a huge role in this video too - all about global warming.
Are They Lying to Us?
What the scientific community has been trying to tell us during the past decades is that we must be careful, because temperatures are rapidly increasing all over the years, and this is happening at the fastest pace it ever happened in million years.
How to Measure the Earth's Temperature
The first thermometer ever invented exploited a very well-known physics principle: thermal expansion. In a nutshell, every material expands when warmed up, and contracts when it cools down. a mercury thermometer consists of a glass tube filled with mercury
Zooming In
So, once we understand how the previous plot was actually made, it is reasonable to take a closer look by zooming in. Let’s go from a scale of millions of years to a scale of thousands of years, and see what the plots tell us! Wow! Look at that! Do you notice anything peculiar?
Human Impact
Alright, so here's the deal: Throughout Earth's history, temperature changes have happened naturally, taking a long time to unfold. But now, things are moving faster. And guess who's to blame? Yep, it's us.
A Reversible Trend
However, we are not completely doomed yet. The potential reversibility of climate change hinges on a combination of factors. At the forefront of this battle is mitigation — the sustained reduction of greenhouse gas emissions.
