Truths like these? It easier to fool a denier than it is flowers and birds. Global Warming Brings Earlier Spring Flowers Starting in 1852 and at different points throughout his life, Thoreau also created the first "spreadsheets of flowering dates" for many well-known flowers, They found that as temperatures warmed over the last 161 years, the date of first blooms of the season crept forward, too — about 10 days earlier than when Thoreau first visited the site. During the record-breaking years of 2010 and 2012, flowering happened a full 20 to 21 days earlier. The average spring temperature at Walden Pond has increased about 6 degrees Fahrenheit (3.4 degrees Celsius) since Thoreau's time. Similarly, at The Shack, as average spring temperatures rose about 3 degrees Fahrenheit (1.7 degrees Celsius) over the last eight decades, first flowering came a week early for the 23 species they studied. During the hottest years in the United States (2010 and 2012), flowering came 24 days earlier than in Leopold's time. livescience.com Climate Change Causing Birds To Migrate Early
