What is climate change, and why should we care?

24.11.20Sustainable & Slow Living1

A little while ago I created a little Instagram graphic/info post explaining what climate change is and why we should care. I thought it would be a good idea to also share the information I found on here as well.

I want to mention, that I researched this information for a radio show that I run with my best friends. All the sources will be linked down below, and if you’re interested in learning more about my radio show, click here.

So, what is climate change?

The Australian Academy of Science defines climate change as a change in the pattern of weather, and related changes in oceans, land surfaces and ice sheets.

It is a change in the statistical properties of our climate system that persists for at least 30 years.

Climate change is caused by a combination of natural processes and human influence. Some natural processes include the sun’s radiation, volcanoes, or internal variability in the climate.

It’s heavily influenced by human activities, such as man-made changes to the atmosphere like greenhouse gasses, deforestation, landfill, and everyday pollution and waste.

Through our actions the Earth’s atmospheric concentrations of carbon dioxide, methane, nitrous oxide and other chemically manufactured greenhouse gases are increasing. These gasses enhance the natural greenhouse gas effect and further warm the Earth’s surface.

Human activities and chemically manufactured greenhouse gases are enhancing and speeding up the natural greenhouse gas effect.

There are connections between temperature, atmospheric water vapour, the extent of ice sheets and the concentrations of long-lived greenhouse gases, especially carbon dioxide, in the atmosphere. When one of these is disturbed, the others react through ‘feedback’ processes that may either amplify or dampen the original disturbance.

Everything is interwined.

Water vapour accounts for approximately half of the natural greenhouse effect. Its concentrations in the atmosphere are controlled by temperatures and winds, which is in contrast to other greenhouse gases that are directly influenced by human actions.

When our global average temperatures rise, global water vapour concentrations increase and amplify the inital warming through an enhanced greenhouse effect. Human activity indirectly leads to increases in water vapour concentrations.

And, these increased concentrations have been observed and attributed to warming, and approximately doubles the sensitivity of the climate to human activities.

Six common causes

  1. Burning fossil fuels
  2. Deforestation
  3. Agriculture and farming
  4. Fast fashion
  5. Landfill
  6. Plastic production and single use waste
Burning fossil fuels

The Intergovernmental Panel on Climate Change (IPCC) has found that emissions from fossil fuels are the dominant cause of global warming. In 2018, 89% of global carbon dioxide emissions came from fossil fuels & industry. Coal is the single largest source of the rising global temperature. Burning oil releases approximately a third of the world’s total carbon emissions (not to mention oil spills). Natural gas is a fossil fuel & accounts for a fifth of the world’s total carbon emissions.

Deforestation

It’s estimated that 25% of the world’s total greenhouse gas production comes from deforestation alone. Forests around the world store more than double the amount of carbon dioxide than is found in the atmosphere. This means that when areas are deforested, the carbon dioxide stored in those trees is released into the atmosphere.

Agriculture & farming

Agriculture & farming can be closely linked to deforestation. The main sources of agricultural greenhouse gases include carbon dioxide from tropical deforestation, methane from livestock and rice production, and nitrous oxide from fertilising or burning croplands. Agriculture is responsible for around half of the global methane emissions & methane is 26 times stronger as a greenhouse gas than carbon dioxide.

Fast fashion

Based on estimated annual global textile production of 60 billion kilograms of fabric, the estimated energy and water needed to produce that 60 billion kgs of fabrics is 1,074 billion KWh of electricity (or 132 million metric tons of coal) and between 6 – 9 trillion litres of water.

Landfill

In 2010, landfill released nearly 800 million tonnes (882 million tons) of carbon dioxide worldwide which is about 11% of all methane generated by humans. Toxins released in landfill also leach into our soil and groundwater, becoming hazardous – particularly electronic waste.

Plastic production & single use waste

Fossil fuels are the building blocks of plastics. It’s estimated that 12.5 to 13.5 million tonnes of carbon dioxide are emitted per year while extracting and transporting natural gas to create feedstocks for plastics in the US alone. This is just the production. In 2019, researchers estimated the production & incineration of plastic pumped out more than 850 million tonnes of greenhouse gases into the atmosphere. As the climate changes, the planet gets hotter, the plastic breaks down into more methane and ethylene, which increases the rate of climate change. It becomes a vicious cycle.

This post only scratches the surface of climate change. Although, I hope it gives you a better understanding on why it’s happening. You can check out my little infographic I made for Instagram below.

Just over halfway through January and I've publish Just over halfway through January and I've published my first blog post of the year 😅

It wasn't my plan, but it's what happened.

Click the link in my bio to head over to my blog to read my hello to 2021 💌

What's something you hope 2021 brings you?
I turned 20 yesterday and I don't like these photo I turned 20 yesterday and I don't like these photos, but I'm posting them anyway.

It's kind of weird to think of myself as a 20 year old. I don't feel ready yet, but I'm ready to give it a go.

Today, I went out and had lunch with my family. It was nothing fancy, but it was nice. I'm not one to celebrate things. To me my birthday is just another day 😅

Anyway, I did have something exciting happen and I'm crossing my fingers it all works out. Anyway guesses?

Outfit details if you're interested:
Earrings are @denzandco
Top necklace is @mejuri and the bottom is @skinstudioj_
Shirt is secondhand Glassons from Depop

Also, when I do post photos of me, would you like to know where my clothes are from?

Heading into 2021 has left me super busy with work Heading into 2021 has left me super busy with work, but full of ideas for the blog.

What have you gotten up to so far this year? 🦋

While work has been crazy, loud, cold, hot, and full on, it hasn't been too bad.

I find January is like a test run of the year. It's a hectic month that's all over the shop (for me at least). Finding peace can be hard, but it's super rewarding. It's a month where I always relearn how to look after myself a little more (after some easily avoidable self-destruction though).

Anyway, I'm heading offline again to get some stuff done as I've got tennis this afternoon 🎾
Happy new year guys 🥂 I've been working the la Happy new year guys 🥂

I've been working the last couple of days, and haven't really spent a lot of time on my phone to post.

To think it's 2021 🤔

For me personally, 2020 was a pretty good year: I did well in uni (could've done better), started building some healthier habits, figured who I am/want to be, hiked, and for the first time felt comfortable in my body. These are all things I hope to carry on into the new year.

I'm definitely trying to look at the positives of 2020.

What's something you achieved in/loved about 2020 despite it being the year no one wanted?
Thought I'd share some sustainable new year resolu Thought I'd share some sustainable new year resolutions to bring into 2021 🌱

These are pretty generic, but I hope they inspire you to think about our gorgeous planet and outside the box for your 2021 resolutions (if you set them).

I've got a blog post up with 10 more sustainable resolutions as well. So, if you want to check out the full list, the link is in my bio 🦋

Even if you just set one sustainable resolution within your list, it's better than nothing. I'd definitely recommend taking a look at number 25 on the list (in my blog post) 🥰

Do you plan on setting any sustainable new year resolutions?
From this morning's hike 💥 I started 2020 on a From this morning's hike 💥

I started 2020 on a high note by hiking Lofty with an incredible friend and it's safe to I'm ending it on a high note too, hiking Wine Shanty with her too (even though there are a few days left).

Even though 2020 didn't go to plan for any of us, I feel closer to myself than ever before and I'm ready to continue growing in 2021.

What was a highlight of 2020 for you?
