Why is Earth's Temperature Increasing?

For today's post, we are going to look at Earth's temperature. If you haven't seen my last post, 'The Three R's' check it out! If you don't know, I have started my new science badge, Environmental Science. I've chosen to post about this topic because we need people to know why our temperature is changing and we need to stop it. This is why our temperature is changing.

One of the reasons Earth's temperature is increasing is because of Pollution. I've made a blog post about Air Pollution and what it does. Here's a preview of the blog post.

You have heard of the word 'Pollution', but do you know what is air pollution. Well, the word 'Pollution' means, effects that harm our environment. Air Pollution means Pollution in the air. Air Pollution is one of the reasons our climate is changing.

Carbon Dioxide's Affect

Carbon Dioxide (CO₂) is a colourless gas. Carbon Dioxide is released by natural processes like volcano eruptions, human activities like deforestation, burning fossil fuels. Humans have increased have CO₂ in the atmosphere by more than a third since Industrial Revolution began. The latest measurement of Carbon Dioxide is 409 ppm (parts per million) in September 2018 (last month). As you see the image below the Carbon Dioxide has increased since the 1950 level.

Here is an image about the Carbon Dioxide increasing since 1950.

How Many Degrees has it Increased?

After learning about Carbon Dioxide and what it does to Earth, let's know how hot is Earth? According to Goddard Institute for Space Studies (GISS), on average, every year, Earth has increased 0.8° since 1880. The warmest year on record is 2016. On the right is an image which shows you the temperature anomaly (long-term average). Below the image, there is a video about the global temperature anomalies it's from 1880-2017. This video is from NASA Climate Change.





As you see in the video, the Carbon Dioxide has mostly increased in the Northern Hemisphere. Temperature has also increased in cold places like Antarctica and Greenland. Below are two videos of ice loss in the Antarctic and Greenland.





Here is a video from NASA Climate Change about Greenland's ice sheet and how it is changing. There are missions studying Greenland: Operation IceBridge, GRACE (Gravity Recovery and Climate Experiment), ICESat 2 (future) and Oceans Melting Greenland (OMG).




What I've Learnt

• Carbon Dioxide (CO₂) is a colourless gas.
• Carbon Dioxide is released by natural processes like volcano eruptions, human activities like deforestation, burning fossil fuels.
• Humans have increased have CO₂ in the atmosphere by more than a third since Industrial Revolution began.
• The carbon dioxide last month was 409 ppm. 
• ppm means 'Parts per million'.
• The carbon dioxide has increased so much from 1950.
• Earth has increased by 0.8° since 1880.
• The warmest year on record is 2016.
• Carbon Dioxide has increased so much in the Northern Hemisphere.
• Every year the average mass of loss is 125 gigaton/year in Antarctica.
• Every year the average mass of loss is 281 gigaton/year in Greenland.
