What we are experiencing not just a normal flux - we have changed the climate!

How do we know our climate is changing permanently, rather than just going through a normal period of flux? Let’s look at 10 major changes scientists have seen in our climate system to help set the record straight.

Few global trends have been as controversial as climate change and the Earth’s warming. The Earth has gone through many shifts in cooling and warming driven by natural factors like the sun’s energy or variations in its orbit, but the trend scientists have seen over the past 50 years is unmistakable.

Let’s take a closer look: globally, average surface temperatures increased 1.1—1.6 degrees Fahrenheit (0.6—0.9 degrees Celsius) between 1906 and 2005. However, it’s the rate of temperature change that’s especially troubling to scientists; temperatures have risen nearly twice as fast in the last 50 years alone.

What other ways has our climate system changed in the last century? How do we really know our climate is changing permanently, rather than just going through a normal period of flux? Between opinions from climate deniers and misinformation campaigns from the fossil fuel industry, it can be a challenge to get the unobstructed facts.

So to help set the record straight, we’re going to focus on 10 major changes scientists have seen in our climate system. Each indicator described below has been extensively studied over the past several decades, and was captured from many different data sets and technologies.
