New study
To curb
Economic growth
Wealthy countries
Make waves
global economy
underestimated
Damage
Caused by humans
By looking at data
From 160 countries
1960 to 2010
13°C
Economically optimal
Agricultural productivity
Many wealthy countries
Temperature
cooler
Benefits
Local economy
Past the peak
Reduces economic productivity
Interesting
Trend
1960
Economies haven't adapted
Hotter temperatures
At first
Economists
No impacts
Wealthy countries
Many resources
To adapt
But
So vulnerable
Beyond 13°C
As poorer
Accumulation / Wealth, technology, experience
Not mitigate
Global economic losses
Study
If we continue
High fossil fuel consumption
Carbon pollution
77% of countries
poorer
2100
Compared with
World where we curb
Global warming
5%-43%
Poorer than today
Disparities
Some colder countries
Benefits
Global warming
But most trade partners
Will be in recession
Poor countries
Contribute the least
Problem
Most vulnerable
Higher social cost of carbon
Integrated Assessment Models
Tools
Estimate impact of climate change
Just these models
are not enough
Economic continue to growth
Cost of the pollution
Via climate damages
Two studies
Economists Moore and Diaz
Professor Marshall Burke
70%-400% per ton
Over 100$ per ton
Underestimate
Economic costs
Climate change
Excluding others factors
Carbon pricing
Price
Reflects estimation social cost of carbon
Consumers react
Economist
Global Warming Policy Foundation
Optimal tax
Some tens and some hundred dollars
Per ton of carbon
Even CEO of the world's biggest oil companies
