Bernal Díaz del Castillo
The best Spanish source on the Aztec–Spanish encounter was written by Bernal Díaz del Castillo, an old campaigner from Cortés’s army. Born and raised in a poor family in Spain, Díaz began his military career as a common soldier. In 1514, he went to America to serve with the Spanish forces opening up the “New World,” and he made two previous expeditions to the Yucatan prior to the one led by Hernando Cortés in 1519. According to his own accounts, he took part in over one hundred battles and was present at the surrender of Tenochtitlan in 1521. After having read a published account of the conquest that he considered a distortion, Díaz set about writing his own account during the 1560s, when he was already an old man. He finished it when he was seventy-six years old. Though he had sent a copy to Spain, the work was not published until the next century, well after his long and eventful life had ended in 1581. The drama of the events and the intimacy and novelty of his observations make this a remarkable historical source.

United Nations Drafting Committee
While there has been considerable debate over the last several decades on the nature and degree of global warming, there is general scientific consensus that greenhouse gases are the main contributors to temperature increases on earth. Scientists generally assume that at current rates of greenhouse gas production the earth will reach a “tipping point” of 450 parts per million, with catastrophic consequences for the planet’s climate, before the middle of this century. Although 169 nations joined the 2005 Kyoto Protocol to reduce greenhouse emissions, the United States refused to sign the agreement. However, the United States did eventually sign on to an international agreement regarding climate change and the reduction of its global threat under President Barack Obama. This framework document, resulting from a conference held in Copenhagen in 2009, pledges the international community to action on the environment, in both specific and principled terms.
