Final Stop

Hello everyone,

Every journey has to come to an end. I hope the past weeks of sharing has helped you learn as much as they have helped me. Previously, I have mostly been sharing on glaciers, but today, I want to look at the bigger picture.

I did a survey on environmental sustainability and asked who/what people thought had the most influence in combating climate change, along with other questions that I will elaborate on later. There were 34 respondents, all of whom were not students in the BES community, and had a wide age range, from 19 to above 65 years old.

Survey respondents

75% of people aged 19-26 thought that governments and corporations had the most influence, while only about 59% of the rest of the respondents thought that way, with more thinking that more influence lies with individuals, or that everybody has a part to play.

Perhaps this has got to do with the younger generation increasingly demanding more government action on climate change, like in other parts of the world. Is this focus on the government perhaps driving the disconnect that the younger generation have between their own actions and climate change?  50% of respondents aged 19-26 thought that their individual actions would have little effect on climate change, compared to 29% of older respondents, from my survey.

Honestly, I believe that the world has to change, but there was a point in time when I was not too convinced that individual actions had an impact at all. Sometimes it felt hopeless, and I often questioned what my actions stood for. But I still tried to make more sustainable decisions anyway, and today it has become somewhat of a habit where I subconsciously choose to live more sustainably.

Research has shown that social influence is a very powerful thing, and one sustainable person can influence many others, and those people can in turn influence more people, and so on. I believe that this, along with the widespread efforts by countries and corporations to reduce emissions, may just be what we need to save the Earth.

I wanted to see if presenting people with some impactful information (in my opinion) could have an effect on how they perceived their individual actions. I presented respondents of my survey with carbon emissions of flights compared to the average carbon emissions of people in several countries, according to a calculator by The Guardian, along with the information that air-cons consume 50 times more energy than fans. 79% said they felt they could contribute more to combat climate change after receiving this information. Perhaps more awareness along with social influence will be able to make all the difference!

Just one flight is enough to cause our emission levels to jump to several times that of average peoples’ emissions around the world. What does this tell us? That many of our lifestyles are unsustainable. Pretty much all of us are guilty, me included. I understand the yearning to travel for leisure, the end-of-year vacation to relief all the stress. But perhaps we should all take a moment to reflect on how much weight our actions can have.

Personally, I hadn’t flown anywhere in 2018 and 2019, only once in February this year to Bali, which produced 470kg of CO2. That is huge.

Researching and writing about glaciers, replying all the comments and reading everybody’s posts have been a refreshing way to learn and see things from so many different perspectives. One thing I have learnt from blogging and conducting surveys is that optimism for a more sustainable world is on the rise, and though I believe there is a lot of work to be done, I want to be a part of that change. Thank you for joining me on this part of my journey 🙂

Ice cores and history

There is a plethora of information we can learn from glaciers. In my past posts I discussed the various ways glaciers are important to us. Today I will be telling you more about the importance of glaciers in helping us understand the Earth’s history.

Ice cores previously found in Greenland are about 130,000 years old and those in Antarctica about 800,000 years old, although an unprecedented find of a 2,700,000 years old ice core was found in 2017. If you want to know more about the drilling and processing of the ice cores, the descriptions and videos here are worth a look!

The amount of information ice cores can tell us is astonishing, at least to me. The air bubbles in the ice tell us about the composition of the atmosphere at different time periods in our history. This includes the carbon dioxide concentration in the atmosphere at those points in time. Other information that can be attained are temperature, precipitation and volcanic activity. Wind patterns can be determined when several ice cores are extracted from areas close to one another, and analysing where precipitation was moved by the wind.

 

So, why is all this important to us? By studying the climate in the past and how different variables like atmospheric carbon dioxide concentrations affect our climate, we are able to predict the changes to come in the future based on our environment now. This is done by climate modeling, and by checking our predictions with what has happened in the past, we are able to better understand the problem of climate change and how to deal with it.

 

I could go on and on about ice cores, but the bottom line is that understanding our history is key to predicting our future. This is true for other fields of study as well, such as in paleontology, where fossil findings in some locations challenge the climate models in places like Alaska. These instances are when new discoveries are born and how we can better understand the Earth.

There have however, been criticisms on the reliability of ice cores, citing reasons such as the drilling of ice cores and their depressurising from being so deep greatly affects the chemistry of the ice cores.

All in all, glaciers are important in many ways, and their persistence is to our benefit.
