1. There are just over 400 billion trees in the world according to NASA spatial mapping -- making that 600 trees per person.
2. More than 50% of the forests of the world have been wiped out since the industrial revolution, whereas world population increased more than 5 times during this period standing at over 7 billion people today. 500 billion trees need to be planted just to return the earth to the position it held until 1750.
3. The United States has by far the greatest amount of carbon emissions in the world, followed by China. But the US emissions per capita are ten times that of a Chinese. We call it the 'Unholy Carbon Capacity.'
4. Greenhouse gasses are the end result of energy generation that is thought to be the single most important component of raising living standards, which theory has now been trashed by proponents of eco-living.
5. North America, Asia and Europe produce 90% of greenhouse gas emissions, whereas the other 3 populated continents of Africa, South America and Australia have a combined share of only 10%!
6. The more the carbon in the atmosphere the more is heat trapped on earth, therefore global warming. Carbon dioxide levels have increase by 1/3rd in 200 years.
7. CO2 concentration in the atmosphere during the ice age was 220 part per million by volume, this grew to 228 ppmv just prior to the industrial age, making that an increase of 160 billion tons in the atmosphere. Today it is close to 400 ppmv, and rapidly rising, bringing the globe to the edge of disaster.
8. Presently the earth's atmosphere is composed of 78% nitrogen, 21% oxygen , and 1% other gases, called greenhouse gases, of which the most important are carbon dioxide and water vapour or humidity which runs to 2% and less. Other greenhouse gases are ozone, nitrous oxide and methane. Greenhouse gases warm the earth's surface by approx. 35° Centigrade by trapping solar heat/energy.
9. Global warming is the balance between the heat generated from the sun as received on earth and the loss of this back into space. Things were going well till the industrial age. Now carbon is being emitted from burning of fossil fuels like petrol, furnace oil, diesel, coal, etc. The more of this that we spew into the atmosphere, the more do they trap heat, not allowing solar heat/energy to return in quantity.
10. 15 million hectares of tropical forests are lost each year -- the size of England. If this pace continues, in 45 years we will have no rain forests left in the world.
11. Why do we need rain forests!? Because they release billions of tons of moisture in the air every day, helping to water crops thousands of miles away.
12. Global warming has the real potential of releasing huge amounts of methane present under ocean beds into the atmosphere, and cause vast areas of the Amazon jungle and other forests to burn, thus releasing even more carbon into the atmosphere and therefore increasing global warming to unsustainable levels.
13. National strategies need to give way to global action. The problem is very serious and some states just dont have the resources to put in place national strategies that are effective. Concerted international action is the only effective recourse.
14. The main source of carbon dioxide is burning of fossil fuels. According to one study Industrialized nations need to reduce carbon emissions to 22 billion tons per annum.
15. The second major cause of carbon emissions is through change of land use from forests to agriculture. This is rampant in South America, Africa and Asia, where food production needs to be increased to feed a growing population. Change in land use is contributing 4 billion to of carbon annually, which is insignificant as compared to fossil fuel burning.
16. Population growth needs to be stemmed more for the global weather than for economic reasons. More people in economic activity means more carbon released into the atmosphere. At present Europe is the most crowded continent on earth.
17. Pakistan experienced a 5°C increase in average summer temperatures in 2015, breaking all records.
