what are some ways to slow down the increase in the CO2 level?

Answer 1

I recommend you look at the "stabilization wedge" materials put together by Robert Socolow and Stephen Pacala at Princeton. They came up with a list of 15 strategies that could be adopted using known technologies. The important point is that these strategies provide results at a large enough scale, so that if we can do just 7 of them, we will avoid the projected increases in annual CO2 emissions over the next 50 years, and therefore prevent the atmospheric CO2 levels from rising above 570ppm (double the pre-industrial level.)

The 15 strategies are:
1. Efficiency –Transport
Increase automobile fuel efficiency (2 billion cars projected in 2050) … 1 wedge = doubling the efficiency of the all world’s cars from 30 to 60 mpg

2. Conservation- Transport
Reduce miles traveled by passenger and/or freight vehicles … 1 wedge = cutting miles traveled by all passenger vehicles in half

3. Efficiency - Buildings
Increase insulation, furnace and lighting efficiency… 1 wedge = using best available technology in all new and existing buildings

4. Efficiency – Electricity
Increase efficiency of power generation … 1 wedge = raising plant efficiency from 40% to 60%

5. Carbon Capture and Sequestration (CCS) Electricity
CO2 from fossil fuel power plants captured, then stored underground (700 large coal plants or 1400 natural gas plants) … 1 wedge = injecting a volume of CO2 every year equal to the volume of oil extracted

6. CCS Hydrogen
Hydrogen fuel from fossil sources with CCS displaces hydrocarbon fuels … 1 wedge = producing hydrogen at 10 times the current rate

7. CCS Synfuels
Hydrogen fuel from fossil sources with CCS displaces hydrocarbon fuels … 1 wedge = producing hydrogen at 10 times the current rate

8. Fuel Switching – Electricity
Replacing coal-burning electric plants with natural gas plants (1400 1 GW coal plants) … 1 wedge = using an amount of natural gas equal to that used for all purposes today

9. Nuclear Electricity
Displace coal-burning electric plants with nuclear plants (2 x current capacity) … 1 wedge = ~3 times the effort France put into expanding nuclear power in the 1980’s, sustained for 50 years

10. Wind Electricity
Wind displaces coal-based electricity (30 x current capacity) … 1 wedge = using area equal to ~3% of U.S. land area for wind farms

11. Solar Electricity
Solar PV displaces coal-based electricity (700 x current capacity) ... 1 wedge = using the equivalent of a 100 x 200 km PV array

12. Wind Hydrogen
Produce hydrogen with wind electricity … 1 wedge = powering half the world’s cars predicted for 2050 with hydrogen

13. Biofuels
Biomass fuels from plantations replace petroleum fuels … 1 wedge = scaling up world ethanol production by a factor of 30

14. Forest Storage
Carbon stored in new forests … 1 wedge = halting deforestation in 50
years

15. Soil Storage
Farming techiques increase carbon retention or storage in soils … 1 wedge = using conservation tillage on all the world’s agricultural soils

Answer 2

GLOBAL WARMING "MARSHALL PLAN":

1. Raise gas taxes by $2 a gallon which would cause people to drive less and buy more efficient cars.
The tax money could be used for all these following projects as well.

1B. use this to buy back all the millions of gas guzzling SUVs which will be melted down to build hybid cars.

2. Immediate moratorium on all sprawl deveolpment.

3. Massivre urban renewal on the scale of the Interstate Freeway program in the 50's so people wont have to commute so far.

4. Massive electric mass transport program linking every neighboirhood by street car and/o light rail.

5. Outlaw all coal fired electric plants and start massive wind power plant development nationwide.

Answer 3

we may be able to do it by following recommendations- a million:Afforestation 2:Controlling speedy inhabitants 3:ideal use of fossil fuels 4:increasing preparation about inhabitants concerns 5:reduce use of CFC and NH3

Answer 4

Plant more plants.
