Climate Change - The Cause
It's clear that our climate is changing - all over the earth.
Can we find out why?
Forget politics, forget politicians, forget people and businesses whose $ depends on life staying the way it is?
Life is changing, the world is changing and not in good ways.
We need to figure out and understand why and what we can do to make it better.
Changing Air - THE Cause.
Gases that catch extra heat from the sun - GASES MADE BY PEOPLE.
1) The best measure of global warming is the ocean heating up.
We measure the heating of the entire ocean by using satellites and lots of bouys spread over all the oceans.
2) If the oceans are heating up, that heat has to come from somewhere.
3) The extra heat comes from the biggest Earth heater there is - the sun.
4) More of the sun's heat is being captured because the air, changed by people, absorbs more of its heat.
5) We measure huge increases in CO2 and other heat catching gases in the air - by planes and satellites.
6) We can measure in the lab that for a specific amount of these gases how much heat these gases absorb from sunlight .
7) We add up all the amounts of these gases in the atmosphere and add up all the heat they absorb, and that is the same as the global warming we measure.
.
What else tells us CO2 is the cause of global warming?
- The lower atmosphere that is gathering the CO2 we make is expanding as it gets warmer, is moving outward the boundary to the upper atmosphere
- Not only that, but we measure that the upper atmosphere is actually cooling, not heating.
- There are two types of Carbon atoms in the CO2 in our air. naturally from plants and animals has Carbon atoms that are slightly different that can easily be measured.
- One type of Carbon comes naturally from plants and animals and one slightly different comes from fossil fuels.
- The difference in Carbon atoms is easily be measured and it tells us that:
- Most of the excess CO2 comes from Fossil fuels that PEOPLE have burned into the air.
- The numbers are huge.
- The amount of CO2 in the atmosphere is far higher than it has been for a long, long time.
Other Possibilities? Probably NOT
Did the Sun get hotter?
The sun’s heat has not increased since at least 1978 (when satellite measuring - outside the earth - began), but global temperatures over the last 30 years have continued to rise.
Did the extra CO2 come from plants?
Is there maybe some unknown natural warm age coming?
Earth's climate has changed naturally over the past 650,000 years, moving in and out of ice ages and warm periods.
Ocean sediments built up over tens of millions of years allows us to compare the past with the present.
This lets us know how much ocean temperatures have changed before we had thermometers.
Over the last 2,000 years, there have been natural climate variations, but they were not especially large compared to what we see now.
Ocean sediments, ice cores, tree rings, sedimentary rocks and coral reefs show that the current warming is occurring 10 times faster than it did in the past when Earth emerged from the ice ages.
Supporting Evidence?
How much is that?
Advances in Climate Modeling?/span>
The mathematical modelling does a good job explaining global warming.
