According to the United Nations, the last decade of the 20th century (1991-2000) was the warmest period in the second millennium (the United Nations Convention to Combat Desertification,UNCCD, 2003). The Inter-Governmental Panel on Climate Change (IPCC), which is attempting to decipher the global climate puzzle using mathematical models that simulate the interactions of land, sea and atmosphere, the 20th century is thought to be the warmest in the past thousand years, presumably the result of human activities (mostly the burning of fossil fuels) that produce greenhouse gases, the accumulation of which contributes to global warming (Cristina Hernández-Espinoza
2003).

Physiology in the 20th century is a mature science
Claude Bernard is France's most famous physiologist and his name is known to physiology students the world over for his idea of the internal environment.
The discovery of the glycogenic function of the liver and of the action of pancreatic juice
Today Bernard is considered one of the founders of experimental medicine.
Bernard was reputedly a very kind person, always ready to help his younger colleagues, a tolerant sceptic who stood out in a France where the hatred between the parties was prevailing. Himself a convinced Orleanist, he was appointed imperial senator for life.
Himself a conscientious investigator, he was an enemy of the charlatanry and oratory that always played the leading roles at the Paris faculty. Bernard invariably failed the competitive examinations for a position as professeur agrégé.
Bernard's most important experimental work may be classified into four areas. Firstly, he showed plasma glucose levels varied in healthy individuals and that a high blood sugar was not necessarily an indication of a disease state. Secondly, this work led to the discovery of the glycogenic function of the liver, which also contributed to knowledge about diabetes. These interests were continued with work on the pancreas and its role in digestion. Thirdly, he discovered vasoconstriction and the nerves that bring about this and vasodilation. This involved work on the sympathetic nervous system. Finally, he studied the oxygenation of arterial and venous blood and was especially interested in toxins, curare and carbon monoxide were his especial favourites.
The constancy of the internal environment is the condition that life should be free and independent
In 1929 by John Barcroft (England, 1872-1947)
W.B. Cannon (America, 1871-1945) who introduced the word homeostasis.
Cannon is particularly remembered for his pioneering contributions to the knowledge of the emergency functions of the sympathetic nervous system and on homeostasis.
The concept of homeostasis was first articulated by the French scientist Claude Bernard (1813-1878) in his studies of the maintenance of stability in the milieu interior. The term itself was coined by American physiologist Walter Cannon, author of The Wisdom of the Body(1932).
From the use of the denervated heart as an indicator of medulliadrenal secretion came the discovery that sympathin is produced in the normal animal. Sympathin is an adrenaline-like substance that is liberated at the tips of certain nerve cells. This disclosure led Cannon into the territory of the chemical mediation of nerve impulses where
"Homeostasis" is derived from the Greek words for "same" and "steady." The term refers to ways the body acts to maintain a stable internal environment in spite of environmental variations and disturbances. Both the mind/brain and the body are endowed with a multitude of automatic mechanisms of feedback-inhibition that counteract influences tending toward disequilibrium.
