Who began the concern that the burning of fossil fuels and the rising levels of CO2 in the atmosphere might affect the climate?
(a)Al Gore - 1995(b)Robert Goddard – 1940(c)Albert Einstein - 1930(d)Charles Darwin - 1870

Arvid Högbom
Swedish Chemist
1857-1940
Högbom was the first scientist to realize that coal combustion could significantly increase the amount of CO2 in the air

Joseph Fourier
French Mathematician
1768-1830
Discovered through mathematical calculations that the earth must be heated with something more than the visible light from the sun.

Last Ice Age
Humans are ‘forcing’ the system in a new way. CO2 increases are mainly due to fossil fuel burning. CO2 has not been this high in more than half a million years.
Last Interglacial
Ice ages are not random. They are 'forced' (by earth’s orbital clock…. changes in the sunlight received).

Svante Arrhenius
1896: Calculated what would happen if atmospheric CO2 changed by 50%.
9 degrees F change in temperature
![Page 15: Climate Change, Energy, and Texas](https://reader036.vdocuments.us/reader036/viewer/2022070400/5681358e550346895d9cfa66/html5/thumbnails/15.jpg)
Gilbert Plass
Canadian Physicist - 1956
Lockheed
Worked on heat(IR)-seeking missiles
spare time: access to one of the first digital computers
– confirmed Arrhenius was right –
CO2 absorbs enough IR that planet is going to warm because of emissions

National average is $18 per person / yearTexas spending at $6 per person / year
Texas: top on coal, near bottom on conservation

The Economics of The Carbon Rule•Texans are paying for carbon emissions and climate change today and
reducing emissions will save Texas money and help drive the economy.
•Texans today are spending $71 per capita and $284 per family of 4 annually for Wyoming coal. Approx. $1.8 billion per year in lost economic opportunity.
•Large and growing federal taxpayer exposures, per year (2012):–$20B Congressional Disaster Appropriations
–$10B National Flood Insurance Program
–$4B to 20B Federal Crop Insurance Program
•$300 per capita from every Texan for 2012 federal weather/climate disaster payments
•Climate and weather disasters in 2012 cost the American economy more than $100 billion.
•CPP climate & health benefits worth an estimated $55-$93 billion per yr in 2030. This includes avoiding 2,700-6,600 premature deaths & 140,000 -150,000 asthma attacks in children
•Outweighs the annual CPP compliance costs of $7.3 billion to $8.8 billion in 2030.
