1) the climate has been remarkably steady over the past 10,000 years
2)

3)
over the previous 50,000 years the climate has undergone abrupt and
dramatic changes
4) carbon dioxide levels in the past correlate well with atmospheric temperature
5) current greenhouse gas levels are well within the Earth's long-term operating
range

Earth's climate has changed dramatically many times since the planet was formed 4.5 billion years ago. These changes have been triggered by the changing configuration of continents and oceans, changes in the Sun's intensity, variations in the orbit of Earth, and volcanic eruptions.Over the last 100 years (1906–2005), global temperature has increased by 0.74°C. ... More regional changes have also been observed, including changes in Arctic temperatures and ice, ocean salinity, wind patterns, droughts, precipitations, frequency of heat waves and intensity of tropical cyclones.
