    According to IPCC Sixth Assessment Report, in the last 170 years, humans have caused the global temperature to increase to the highest level in the last 2,000 years. The current multi-century period is the warmest in the past 100,000 years. [3] The temperature in the years 2011-2020 was 1.09 °C higher than in 1859–1890.

    The Huang, Pollack & Shen 2000 borehole temperature reconstruction covering the past five centuries supported the conclusion that 20th century warming was exceptional. [ 71 ] In a perspective commenting on MBH99, Wallace Smith Broecker argued that the Medieval Warm Period (MWP) was global.

    Global warming affects all parts of Earth's climate system. [19] Global surface temperatures have risen by 1.1 °C (2.0 °F). Scientists say they will rise further in the future. [20] [21] The changes in climate are not uniform across the Earth. In particular, most land areas have warmed faster than most ocean areas.

    An early (2018) warming stripes graphic published by their originator, climatologist Ed Hawkins. [1] The progression from blue (cooler) to red (warmer) stripes portrays annual increases of global average temperature since 1850 (left side of graphic) until the date of the graphic (right side).

    Global warming projections from AR4 [3] are shown below. The projections apply to the end of the 21st century (2090–2099), relative to temperatures at the end of the 20th century (1980–1999). Add 0.7 °C to projections to make them relative to pre-industrial levels instead of 1980–1999. (UK Royal Society, 2010, p=10 [citation needed]). [5]

    World leaders are meeting in Paris this month in what amounts to a last-ditch effort to avert the worst ravages of climate change. Climatologists now say that the best case scenario — assuming immediate and dramatic emissions curbs — is that planetary surface temperatures will increase by at least 2 degrees Celsius in the coming decades.
