The Wikipedia article of the day for October 19, 2017 is Henry III of England.
Henry III (1207–1272) was King of England from 1216 until his death. The son of King John and Isabella of Angoulême, Henry assumed the throne when he was only nine in the middle of the First Barons’ War. He was known for his piety, holding lavish religious ceremonies, giving generously to charities, and adopting Edward the Confessor as his patron saint. In 1230 he attempted to reconquer the provinces of France that had once belonged to his father, but the invasion was a debacle, and a revolt broke out in 1232. He invaded Poitou in 1242, leading to the disastrous Battle of Taillebourg. In 1258 a coalition of his barons seized power in a coup. Henry and the baronial government enacted a peace treaty with King Louis IX of France in 1259, under which Henry gave up his other lands in France in return for recognition as the rightful ruler of Gascony. In 1263 one of the more radical barons, Simon de Montfort, seized power, resulting in the Second Barons’ War. At the Battle of Lewes in 1264, Henry was taken prisoner. His eldest son, Edward, defeated de Montfort at the Battle of Evesham the following year and freed his father.

The Wikipedia article of the day for October 18, 2017 is Ice core.
An ice core is a core sample that is typically removed from an ice sheet or a high mountain glacier. Cores are drilled with hand augers (for shallow holes) or powered drills; they can reach depths of over two miles, and contain ice up to 800,000 years old. The physical properties of the ice and of material trapped in it can be used to reconstruct the climate over the age range of the core. The ratio of oxygen and hydrogen isotopes provides information about ancient temperatures, and the air trapped in tiny bubbles can indicate the level of atmospheric gases such as carbon dioxide. Greenland ice cores contain layers of wind-blown dust that correlate with cold, dry periods in the past. Radioactive elements, either of natural origin or created by nuclear testing, can be used to date the layers of ice. Some volcanic events that were sufficiently powerful to send material around the globe have left a signature in many different cores that can be used to synchronize their time scales. Climate models can be constructed by piecing together all the available data.
