Earth's surface and the clouds absorb visible and invisible radiation from the sun and re-emit much of the energy as infrared back to atmosphere. Certain substances in the atmosphere, chiefly cloud droplets and water vapor, but also carbon dioxide, methane, nitrous oxide, sulfur hexafluoride, and chlorofluorocarbons, absorb this infrared, and re-radiate it in all directions including back to Earth. Thus, the greenhouse effect keeps the atmosphere and surface much warmer than if the infrared absorbers were absent from the atmosphere.
After Earth absorbs methane, in what spectrum is it re-emitted?
A: unanswerable

A number of novel ideas about religion developed with the Enlightenment, including Deism and talk of atheism. Deism, according to Thomas Paine, is the simple belief in God the Creator, with no reference to the Bible or any other miraculous source. Instead, the Deist relies solely on personal reason to guide his creed, which was eminently agreeable to many thinkers of the time. Atheism was much discussed, but there were few proponents. Wilson and Reill note that, "In fact, very few enlightened intellectuals, even when they were vocal critics of Christianity, were true atheists. Rather, they were critics of orthodox belief, wedded rather to skepticism, deism, vitalism, or perhaps pantheism." Some followed Pierre Bayle and argued that atheists could indeed be moral men. Many others like Voltaire held that without belief in a God who punishes evil, the moral order of society was undermined. That is, since atheists gave themselves to no Supreme Authority and no law, and had no fear of eternal consequences, they were far more likely to disrupt society. Bayle (1647–1706) observed that in his day, "prudent persons will always maintain an appearance of [religion].". He believed that even atheists could hold concepts of honor and go beyond their own self-interest to create and interact in society. Locke said that if there were no God and no divine law, the result would be moral anarchy: every individual "could have no law but his own will, no end but himself. He would be a god to himself, and the satisfaction of his own will the sole measure and end of all his actions".
Which philosopher argued that without belief in a God who punishes evil, the moral order of society was undermined?
A: Voltaire

Perhaps the most prominent, controversial and far-reaching theory in all of science has been the theory of evolution by natural selection put forward by the British naturalist Charles Darwin in his book On the Origin of Species in 1859. Darwin proposed that the features of all living things, including humans, were shaped by natural processes over long periods of time. The theory of evolution in its current form affects almost all areas of biology. Implications of evolution on fields outside of pure science have led to both opposition and support from different parts of society, and profoundly influenced the popular understanding of "man's place in the universe". In the early 20th century, the study of heredity became a major investigation after the rediscovery in 1900 of the laws of inheritance developed by the Moravian monk Gregor Mendel in 1866. Mendel's laws provided the beginnings of the study of genetics, which became a major field of research for both scientific and industrial research. By 1953, James D. Watson, Francis Crick and Maurice Wilkins clarified the basic structure of DNA, the genetic material for expressing life in all its forms. In the late 20th century, the possibilities of genetic engineering became practical for the first time, and a massive international effort began in 1990 to map out an entire human genome (the Human Genome Project).
Which scientist championed the idea of evolution?
A: Charles Darwin

Politically, the paper's stance was less clear under Prime Minister Gordon Brown who succeeded Blair in June 2007. Its editorials were critical of many of Brown's policies and often more supportive of those of Conservative leader David Cameron. Rupert Murdoch, head of The Sun's parent company News Corporation, speaking at a 2007 meeting with the House of Lords Select Committee on Communications, which was investigating media ownership and the news, said that he acts as a "traditional proprietor". This means he exercises editorial control on major issues such as which political party to back in a general election or which policy to adopt on Europe.
Who was the Conservative leader that The Sun often supported?
A:
David Cameron
