The Country Most Vulnerable to Climate Change

By Hakim Abdi, June 12, 2017

Of the 186 countries assessed in a recent survey of climate vulnerability, Chad was rated most in peril. A combination of high poverty, frequent conflicts, and the risk of both droughts and floods means the central African nation is bottom of the list, just below Bangladesh and some way behind Norway, the country least vulnerable to climate change.

So why Chad? For a start, it is one of the poorest countries in the world. Around 87% of Chadians are classified as poor, according to the Multidimentional Poverty Index, which factors in health, education and living standards.


This is exacerbated by the fact that the country has been in civil war or conflict for 35 out of the 57 years since it gained independence from France.

Any poor or conflict-prone country will always be vulnerable, but Chad’s geography means climate change is a particular risk. Chad is bigger than many Westerners may realise. At 1.28m km² it’s larger than Nigeria and twice the size of Texas. Around 90% of its 10m people live in the southern half of the country, as most of the northern half extends well into the Sahara desert.


Since the mid-20th century, temperatures in Chad have been increasing while rainfall is decreasing. Ninety percent of the country’s largest lake, Lake Chad, has disappeared over the past 50 years due to a combination of droughts and increasing withdrawals for irrigation. Climate studies project things will get increasingly hot and arid throughout the 21st century, which means lower crop yields, worse pasture, and a harder life for anyone dependent on Lake Chad.


The Conversation


  1. Chad is one of the poorest nations on Earth.  
  2. Chad has been at war for 61% of the last 57 years. 
  3. 90% of the population lives in the part of Chad not in the Sahara Desert. ✓ 
  4. Chadians have drained 90% of their largest lake over the past 50 years. 
  5. Climate models predict that it will get worse. AEUHHH????

Only one of the above is truly related to “climate change.”  Any guesses as to which?  Vanishing Lake Chad?  No.  This is due to droughts of the 1970’s and 1980’s (when global cooling was the crisis du jour), the lake’s unique bathymetry and agricultural withdrawals (Gao et al., 2011).   According to hydrological models, by the year 2000, Lake Chad would have recovered to 82% 1963 area and 59% of its volume, if not for the agricultural withdrawals and unique bathymetery.

In warm desert, warm semi-arid and tropical savanna climates, droughts *are* climate, not climate change.  So, the answer is #5: “Climate models predict that it will get worse.”

Climate models are apparently so good that they can predict that the worst place on Earth, with a nearly uninhabitable climate, will get worse due to climate change?

Can anyone identify this logical fallacy?  How can you cite the hydrological model of Lake Chad, while ridiculing climate models?  If you criticize one type of model, you must criticize all models!

Can Chad’s climate realistically get worse?  For starters, Chad appears to be invulnerable to CAGW’s chief bogeyman: Sea Level Rise…

So… They got that going for them… Unfortunately, that’s where the good news ends.

Eyeballing a Köppen climate classification map of Chad, it appears that about 65% of the country is warm desert (BWh), 20% is warm semi-arid (Bsh) and about 15% is tropical savanna (Aw).

With most of Chad being unsuitable to agriculture largely due to a lack of water… could climate change really make things any worse?  It’s hot.  It’s dry.  It’s been hot and dry longer than there are modern weather records.  Could it really get worse?

The capital city of Ndjamena was already very hot before the 97% consensus decided that humans were responsible for at least half of whatever happened since 1950:


Ndjamena: Average annual temperature (°C). In 1950, at the start of the 97% consensus that humans caused everything since 1950, the average annual temperature was already 27.4 °C (81.3 °F). It’s now up around 29.3 °C (84.5 °F). Assuming the 97% consensus is correct and not fictitious, Ndjamena’s average annual temperature might only be 83.8 °F… Much more habitable than 84.5 °F… (Yes, I am being sarcastic). https://data.giss.nasa.gov/cgi-bin/gistemp/show_station.cgi?id=110647000000&dt=1&ds=12


That’s the annual average, including nighttime and winter.  The climate has literally gone from uninhabitable to uninhabitable and the climate models say it will likely get worse!!!

We can see how severely (or not) the Chadian climate changed over the 20th Century on these historical Köppen climate classification maps from Rubel & Kottek (2010):


Chad’s 20th century climate change. Yellow = Warm Desert (BWh), Gold = Warm Semi-Arid (BSh) and Pink = Tropical Savanna (Aw). (Source Rubel & Kottek, 2010).

History says Chad’s climate has been bad since at least 1900.  The models say Chad’s climate will get worse.  The models have a very good track record of being wrong.

Whatever happens to Chad’s climate, Sam Kinnison offered a solution to this sort of  climate problem back in the 1980’s… (Warning, Sam Kinnison cussed a lot)…

As usual, any and all sarcasm was very intentional.
