More Bad Climate News This Christmas
By Woody Chan 18 December, 2019
Want to stay in blissful ignorance this festive season? If not, face the music with our review of recent climate reports
Yet again, bad news on our climate crisis just before Christmas. It’s no surprise that we are still not on track to closing our emissions gap with our emissions rising another 3.4% this past year. The consequences are going to be disastrous but it could be even worse given instabilities in the Arctic. With Asia set to be hit hardest, can it take the lead in climate adaptation this coming decade and prevent its capitals from sinking?
You can wallow in blissful ignorance this Christmas but if you’d rather take the blinkers off then you cannot miss the key reports that came out in the past month, from the IPCC to UNEP. With some of these over a thousand pages long – we’ve got you covered. Here are our five top takeaways.
1. Asia under water? Sea level rising faster than we thought
Back in 2014, the IPCC came out with sea level projections as part of its Assessment Report 5 (AR5). Now, five years on in its Special Report On Ocean & Cryosphere, it turns out the seas are rising faster than expected. For instance, there is medium confidence that for a high emissions scenario (RCP8.5), projections of global sea level rise by 2100 are 0.1m greater than in AR5 due to a larger contribution from the Antarctic Ice Sheet. And just in case you haven’t heard – this scenario is now our new base case.
Many Asian capitals & financial hubs to be impacted
Threats posed by sea level rise and storm surges are going to have disastrous consequences for Asian cities, many of which are along the coast and capitals or major financial hubs, from Bangkok to Shanghai. We have already looked at what this could mean for Hong Kong.
You may also have come across some shocking maps from Climate Central and while they are not perfect, they give a good indication of where we are heading.
2. Extreme sea level events every year by 2050
Remember Typhoon Mangkhut? Or Hurricane Katrina? These extreme sea level events have been historically rare but are now projected to happen at least once every year by 2050 in all scenarios, especially in tropical regions where we in Hong Kong are located. Already we have seen two super typhoons in two consecutive years in 2017 and 2018.
“By 2100 Hong Kong should be expecting a Typhoon Mangkhut every year”
Don’t just take it from us. We were lucky to have talked to the head of the Hong Kong Observatory recently , who informed us that by 2100 HK should be expecting a Typhoon Mangkhut every year. Also, he warns of a 1m sea level rise and total storm tides of more than 7m (aligning with our new base case). How ready are we really?
3. Not on track – need to stop emitting & cut back
All this means we should be drastically cutting down on our emissions but as the UNEP Emissions Gap Report 2019 shows, that is far from reality. Instead of going down, our global greenhouse gas emissions actually increased again from 53.5GtCO2e to 55.3GtCO2e in the past year. This leaves us with just 11 years to cut 14.3GtCO2e by 2030 if we are to meet the Paris Agreement target of +2°C by 2100.
4. The science is correct – 50-year projections from 70s proven right
We can already hear some climate deniers crying “fake news”… so how good are these projections?
According to a new paper published in Geophysical Research Letter, almost every peer-reviewed climate model of human-caused global temperature rise dating back to 1970 lines up with the warming we see today. Out of the 17 models analysed by the authors, 14 correctly predicted how much the earth would warm based on how much CO2 was in the atmosphere. So they have been right on the money all this time.
If we keep dragging our feet, we will hit 4.5°C & the impacts will be disastrous
Not only does this debunk climate deniers’ claim that climate models are unreliable and inaccurate, but it further underlines the message from the IPCC and UNEP reports. The science is correct: if we keep dragging our feet, we will hit 4.5°C this century and the impacts will be disastrous.
5. Oh no we forgot about feedback loops
As if this weren’t bad enough, enter feedback loops, which are set to kick in to make the planet go haywire.
Take the Arctic for instance. According to the new 2019 Arctic Report Card, the Arctic may have crossed a threshold to become a net carbon emitter due to thawing permafrost, which is carbon-rich frozen soil that covers 24% of the Northern Hemisphere’s land mass. The report concludes that the Arctic and other permafrost ecosystems could already be releasing as much as 1.1GtCO2e to 2.2GtCO2e per year. This is almost as much as the annual emissions of Japan and Russia in 2018, respectively.

What’s more, 2100 is not a cut-off – we face an ultimate sea level rise of between 4–10m or more
What’s more we have to remember that climate change does not stop in 2100, despite many studies and policies using the end of the century for projections. In reality, beyond 2100, the climate crisis deepens and we face an ultimate sea level rise of between 4–10 meters or more.
Asia most exposed – need to step up
As those at COP25 struggle with mitigation actions and as the US withdraws from the Paris Agreement, it’s down to Asia to step up. We need to think radical and adapt to the new climate. We need to build resilience. We need to protect our assets and infrastructure.
