Hockey stick graphs present the global or hemispherical mean temperature record of the past 500 to 2000 years as shown by quantitative climate reconstructions based on climate proxy records. These reconstructions have consistently shown a slow long term cooling trend changing into relatively rapid warming in the 20th century, with the ...
Projected global surface temperature changes relative to 1850–1900, based on CMIP6 multi-model mean changes. The IPCC Sixth Assessment Report defines global mean surface temperature (GMST) as the "estimated global average of near-surface air temperatures over land and sea ice, and sea surface temperature (SST) over ice-free ocean regions, with changes normally expressed as departures from a ...
There is good agreement on the overall evolution of global temperatures and year-to-year variability. Dataset anomalies are calculated relative to a 1981 to 2010 baseline and offset by 0.69°C, which is the best estimate difference for that period from the 1850-1900 average given in the IPCC sixth assessment report."

Top chart: Earth's climate has cycled between ice ages and warm interglacial periods, with each cycle taking tens of thousands of years or more. Middle chart: Global average temperature was in a cooling trend for thousands of years before fossil fuel based industrialization. Since then, it has increased about a full 1°C—in a time period less ...
English: Video showing most recent ~140 years of global warming in the perspective of the last ~2000 years. Method: I simplified the two source SVG images (below) in Inkscape, exported to big PNG files, and used Photoshop Elements to generate 59 frame-by-frame PNG images for Shotcut to generate the continuous transition this webm video.

A hockey stick graph or hockey stick curve is a graph, or curve shape, that resembles an ice hockey stick, in that it turns sharply from a nearly flat "blade" to a long "handle". In economics , [ 1 ] [ 2 ] marketing , [ 3 ] and dose–response relationships , [ 4 ] [ 5 ] a hockey stick graph is one in which the "blade" is near zero (hugging the ...
