Olivia Shakespear (1863–1938) was a British novelist, playwright, and patron of the arts. She wrote six books that are described as "marriage problem" novels. Her works sold poorly, sometimes only a few hundred copies. Her last novel, Uncle Hilary, is considered her best. She wrote two plays in collaboration with Florence Farr.

Yeats went on to marry Georgie Hyde-Lees, Olivia's step-niece and her daughter Dorothy's best friend. Olivia began hosting a weekly salon frequented by Ezra Pou

Global warming is the rise in the average temperature of Earth's atmosphere and oceans since the late 19th century, and its projected continuation. Since the early 20th century, Earth's mean surface temperature has increased by about 0.8 °C (1.4 °F), with about two-thirds of the increase occurring since 1980.[2] Warming of the climate system is unequivocal, and scientists are more than 90% certain that it is primarily caused by increasing concentrations of greenhouse gases produced by human activities such as deforestation and the burning of fossil fuels.[3][4][5][6] These findings are recognized by the national science academies of all major industrialized nations.
