Since then, it has increased about a full 1°C—in a time period less than 1/3,000th the width of the top chart. Bottom chart: This 1°C increase, commonly called global warming, accelerated since 1980—a period less than 1/20,000th the width of the top chart. SOURCES (and related explanations): 1. Top chart (800,000 years): — Data itself:
The following day (10 May), Jason Samenow wrote in The Washington Post that the spiral graph was "the most compelling global warming visualization ever made", [27] and, likewise, former Climate Central senior science writer Andrew Freedman wrote in Mashable that it was "the most compelling climate change visualization we’ve ever seen". [28]
— Data uses 1901-2000 base period (=0°C in the chart). Actual data for this chart is provided in expandable text, below. FYI: Data, adjusted for a different base period, is used in the top half of uploader RCraig09's other image file: File: 20190727 COMPARE warming stripes - Global vs Caribbean 1910-2018 (ref 1910-2000).png
The high elevation areas of Asia, Africa, and Antarctica saw elevation dependent warming (EDW), while those in North America and India saw elevation dependent cooling (EDC). [13] The latitudinal climate gradient is generally believed to have been smaller, which was mainly the result of a decrease in albedo differences across Earth's surface. [14]
The cover of the "Climate Issue" (fall 2020) of the Space Science and Engineering Center's Through the Atmosphere journal was a warming stripes graphic, [91] and in June 2021 the WMO used warming stripes to "show climate change is here and now" in its statement that "2021 is a make-or-break year for climate action". [56]
The generally strong dependency on elevation is known as altitudinal zonation: the average temperature of a location decreases as the elevation increases. The general effect of elevation depends on atmospheric physics. However, the specific climate and ecology of any particular location depends on specific features of that location.
In 2003, as lobbying over the 1997 Kyoto Protocol intensified, efforts by the Bush administration to remove climate reconstructions from the first Environmental Protection Agency and Jim Inhofe's Senate speech claiming that man-made global warming is a hoax both drew on the Soon and Baliunas controversy. [17]
Finally, when asked about the 1990 IPCC estimate of warming proceeding at 0.3 °F (0.17 °C) per decade throughout the 21st century under the business-as-usual climate change scenario, 13 (15%) expressed skepticism, 39 (44%) had emphasized uncertainty, and 37 (42%) had agreed. 52% thought the rate of warming would likely be lower, and 8% ...
