The other day I stumbled upon this on my twitter feed:
While I strongly believe that climate change deniers constitute a very vocal minority with an oversized internet megaphone, I still physically cringed when I saw that tweet. Fortunately, there is an overwhelming consensus in the scientific community that global warming is a real issue which can manifest itself in many ways (including more intense weather conditions like the blizzard the girl is posing in). In fact, there is an entire international group dedicated to quantifying climate change and its implications on the world – the Intergovernmental Panel on Climate Change (IPCC).
The IPCC is UN’s massive team of scientists dedicated to conducting research on climate change; their main goal is to churn out reports that can inform governments on the ‘what’s, ‘why’s and ‘how’s of everything related to climate change. Just last year, they published SR15, a report which was honestly quite scary for someone like me who had only just begun to learn about the environment in depth.
Essentially, the report concluded that we must limit global temperature rise to 1.5°C instead of 2°C by 2030 (at the very latest) or we risk causing too much irreversible damage. The entire report itself is way too comprehensive and detailed for any average person to fully read through, which means that even their executive summary is 30 pages long!

For Singapore and the SEA region in general, the main concerns include climate change’s impact on marine biodiversity and ecosystems. To put things into perspective, it is predicted that by 2050, a global temperature rise of 1.5°C will drive the decline of 70% to 90% of all coral reefs; with a rise of 2°C or more, more than 99% are at risk! It is indeed quite disheartening to think that it is possible see the loss of such large ecosystems in our lifetimes.
Beyond the risk of species extinction and shrinking marine populations, this may also affect our local food supply. With increasing ocean acidification and rising sea levels, global warming has already been observed to cause declines in the productivity of fisheries and aquaculture; considering the fact that crop yields and the nutritional value of these crops are also expected to diminish, this spells some trouble for global food security.
Apart from affecting marine resources, SR15 studied over 10,000 species and found that among them, 18% of insects, 16% of plants and 8% of vertebrates will lose more than half of their habitat ranges. This is definitely not surprising when you look at the spate of recent extinctions and a growing list of endangered species.
There are other implications as mentioned in SR15, of course, and I would recommend anyone truly interested to read the executive summary. Otherwise, here are some pretty neat infographics by WWF:
Fortunately, Singapore takes climate change quite seriously. In fact, the recent Singapore Budget 2019 addressed a bit of how our country has and will continue to adapt and mitigate. Quite in tandem with what SR15 suggests, we have a mix of adaptation and mitigation strategies in response to global warming. For instance, the budget includes how we have some infrastructural adaptations to rising sea levels and also some mitigation measures like restructuring diesel taxes. Notably, last year’s plan to implement a carbon tax has finally been implemented at the start of 2019.
As average Singaporeans, there’s so much we can do to contribute to the cause! Besides the usual advice of going vegetarian or using less disposables, it is also important to be open minded and help spread the good word to those that are not aware of the pressing issues surrounding climate change. Perhaps this is best done by inspiring a love for nature in them first, and perhaps this can be done by inviting them for a nature walk with us!
