I saw last week An Inconvenient Sequel by Al Gore, the sequel of 2006 hit documentary, An Inconvenient Truth. I have mix feelings about it.
It seems the huge floods in the United Kingdom could become the new normal because of climate change. The frequency of such destructive events could almost double by mid century as a new study published in Nature Climate Change reports. According to the Guardian :” The huge cost of flood damage is set to soar … Read more
You must have heard or read about it : Friday, the Intergovernmental Panel on Climate Change has published the first part of its latest report. The results are even more frightening than in 2007 and stress how urgent action is needed.
Now the IPCC is between 95 percent sure that most of the warming is human made. To me that doesn’t make much difference since the previous report stated that it was 90 percent sure. That was already enough to urge us toward action.
By the end of the century global temperatures could rise by 4.8°C, compared to an agreed goal of 2°C of increase. This is still achievable but would require huge action quickly.
This was the question asked on the the Yale Environment 360 blog and I believe the timing is perfect as last year cities such as New York City, Manila and Bangkok got it by record floods. Now it is the turn of Jakarta.
The capital megacity of Indonesia now has water in its streets and people to evacuate because of another flood. Given that rising temperatures mean rising sea levels and more extreme weather, the threat is huge.
First in terms of people – as the majority of people will live in cities in 2050 and as 14 of the world’s 17 largest cities are located along coasts.
Unless you have spent the week remote from civilization, you must have heard of THE event of the week : Disney bought the Star Wars franchise. Ooops, sorry, I meant : Hurricane Sandy, also known as the Frankenstorm.
All joking aside, the matter is tremendously serious as dozens died in the Caribbean and the United States. Billion of Dollars of damages will probably be recorded as New York and many other cities were flooded.
Manila, Jakarta and Kolkata (formerly known as Calcutta) would be threatened the most. Others cities, including Mumbai (Bombay), Delhi, Chennai, Karachi, Lagos and Guangdong, would also be in danger.
This reminds me of a series of posts I had published here as early as 2008 on that very subject. This time, the research had been carried out by the OECD and the World Bank.
It seems many people will have to flee their homes. Indeed, many islands like Tuvalu and the Maldives (pictured) may disappear from the surface of our planet by mid-century.
Today I propose you some of the latest articles on that topic. Climate change is happening right now, those islanders witness it as you read this.
As we saw three weeks ago in my article on the scientific data on level sea rise, the melting of both Arctic and Antarctica are one of the main components of the phenomenon.
Even if the Arctic is quite well documented, Antarctica is not that well known. 25 times bigger than France and weighting billions of tons of ice, the sixth continent is a huge unknown.
If a single percent of all this ice melt, it would represent a sea level rise by a staggering 60 centimeters (two feet)… A serious danger I will study today.
Even if it won’t be the most stricken by the phenomenon, it would suffer from dire consequences of rising sea levels provoked by a full scale climate change.
You will find below an overview of the main cities, regions and economic activities that will be the most hit. The list is quite impressive.
After last week’s article on the scientific data of rising sea levels, it is time for us to have a look at how they would affect millions of people and possibly destroy assets worth billions.
The OECD report mentioned last week gives us further data on this very topic and the least I can say is that the situation is truly frightening with possible catastrophes in many countries.
The vast majority of risks are located in Asia, and more particularly in India and China as their coastal populations are due to increase in an important way.
