Nearly a century ago, the British scientist John Tyndall suggested that a fall in the atmospheric carbon dioxide could allow the earth to cool whereas a rise in the carbon dioxide would make it warmer.
Earth warming: Yes, carbon dioxide in the atmosphere is considered a cause of earth warming.
Northern waters are able to absorb and hold more gases, particularly carbon dioxide, which is growing steadily in the Earth's atmosphere.
Other scientists say it may have been 10 million years ago that Earth last encountered this much carbon dioxide in the atmosphere.
But Friends of the Earth say that an increase in carbon dioxide emissions is a price worth paying to protect the ancient landscape of the Blackdown Hills.

Around eight percent of the earth's forest carbon storage is trapped in the DRC's 86 million hectares of rainforest.
Forty million years ago, when the earth was warmer because there was more carbon dioxide in the air as a result of volcanic eruptions, the oceans are thought to have been 70 meters (or 229 feet) higher.

Although you went on to recognise that human activity causes these natural flows to become unbalanced, it can actually take only two or three decades for humans to cumulatively emit an amount that matches those natural fluxes, given how long carbon dioxide persists in the atmosphere and the low amount that the earth can absorb each year.
Only 44% of Americans believe that carbon dioxide emissions are warming the Earth, down from 51% in 2009, and 71% in 2007.
Greenhouse gases still warm planets, carbon dioxide is still a greenhouse gas and the amount of it in the Earth's atmosphere is still shooting up.
Greenhouse effect: heating of the earth's atmosphere due to an increase in gases like carbon dioxide.
The amount of carbon dioxide varies daily somewhat and has cycled historically in accordance with changes in the Earth's orbit, a phenomenon known as Milankovitch cycles.
Since then, the concentration of carbon dioxide has in fact increased and the mean temperature of the surface of the earth has increased in pretty much the way Dr. Arrhenius said it would.

Carbon-rich worlds contrast sharply with the Earth, whose interior is relatively poor in that element but rich in oxygen.
The three conventional forms of fossil carbon oil, coal and gas differ both in the way the Earth stores them and the way its people use them.
The other approach is less risky, and involves removing carbon directly from the atmosphere and burying it in vast ocean storage beds or deep inside the earth.
So, its of no surprise, when looking at long term ice core sample and ocean core deposits, they indicate as the Earth warms, so does the carbon footprint from the increase carbon produced high in the atmosphere.

Arrhenius predicted that if the carbon dioxide concentration increased, the mean temperature of the surface of the earth would increase, in pretty much the way he said it would.

The president would oversee bi-partisan legislation to limit carbon dioxide -- the main "greenhouse gas" blamed by many scientists for trapping heat in the earth's atmosphere -- from U.S. power plants for the first time, she said.
Carbon dioxide levels in the atmosphere are currently the highest on record, according to preliminary data from the Earth Systems Research Laboratory at Mauna Loa in Hawaii where measurements of CO2 have been recorded for nearly half a century.
In a joint statement in August 2006 Greenpeace, the WWF and Friends of the Earth said: "Carbon offsets should only be seen as a last resort" and that "purchasing offsets can be seen as an easy way out for governments, businesses and individuals to continue polluting without making changes to the way they do business or their behavior".
But before Westerners begin pointing fingers at Asian countries for contributing to greenhouse gases and other anti-sustainability actions, it should be understood that while they may be growing in their contributions to deleterious effects on the earth, they still lag far behind western nations in terms of per capita production of Carbon Dioxide, the greenhouse gas identified as the greatest contributor to climate change.
