It is the “leading international body for the assessment of climate change,” * The first IPCC report (1990) contains the following graph of average global temperature changes over the past 1,000 years based upon proxies.

It shows a “Medieval warm period” that was warmer than the present era and a “Little Ice Age” that was cooler.

Hopefully it will give some insight into the science and the people behind it.[129] [130] Look at the instrumental record!

There are huge differences between different regions - Alaska has warmed substantially while eastern North America cooled after the 1950s.

The materials were authored by some of the world’s leading climate scientists and accompanied by the following note: We feel that climate science is too important to be kept under wraps.

We hereby release a random selection of correspondence, code, and documents.

K., the Earth’s average temperature warmed by 1.4ºF (0.8ºC) between the 1850s and 2000s, mostly during 1911-19-1998: * Sources of uncertainty in surface temperature data involve “very incomplete” temperature records in the earlier years,[58] “systematic changes in measurement methods,”[59] “calculation and reporting errors,”[60] [61] [62] [63] [64] [65] [66] data adjustments that are performed when instruments are moved to different locations,[67] instrument precision,[68] instrument positioning,[69] and missing documentation/raw data.[70] [71] definitive assessment of uncertainties is impossible, because it is always possible that some unknown error has contaminated the data, and no quantitative allowance can be made for such unknowns.[72] * Oceans constitute about 71% of the Earth’s surface.[73] Changes in air temperature over the world’s oceans are typically based on measurements of water temperature at depths varying from less than 3 feet to more than 49 feet.[74] [75] This data is combined with changes in air temperature over land areas to produce global averages.[76] [77] contrasted water and air temperature changes in the tropical Pacific Ocean using three sources of measurements.The report states that: some of the global warming since 1850 could be a recovery from the Little Ice Age rather than a direct result of human activities.
