I have travelled from London to Sydney to join the Catlin Seaview Survey. It promises to be an amazing experience, learning more about the Great Barrier Reef and coral in general.
Over the next three weeks, I shall be visiting different parts of the reef and speaking to the science teams who are investigating the health of this ecosystem.
One of the areas of investigation is how climate change is affecting the reef and the damage that it can cause. Increased CO2 in the atmosphere affects coral reefs in three main ways:
- warming oceans can cause ‘coral bleaching’ where the symbiotic relationship between coral and algae breaks down, so that the coral loses a major energy source and can die
- climate change is also linked to increased storm activity that causes physical damage to the reef
- more carbon dioxide in the atmosphere, increases the amount of carbon dioxide in the oceans, causing ocean acidification and adding to the stress on this fragile environment
It’s a difficult choice. Can I be of benefit to the reef by coming here and helping to communicate its wonders or stay at home and let others do this work?
Can you help in calculating my carbon footprint for this journey so far and if possible compare it to the average annual carbon footprint for the UK?
Here’s how I travelled…
7.5 miles by taxi from my house to Paddington Station
A total of 27 miles by train
10,673 miles by aeroplane from London to Sydney via Singapore
And the last (and nicest) leg by ferry to a part of Sydney called Manly – 7 miles
