Is this temperature increase an estimate or a projection based upon verified measurements over a statistically valid time period? How much confidence is there in these numbers?Scientists and researchers around the world have been warning us about the adverse effects of climate change for many years. They have made it clear that if we continue to emit greenhouse gases at the current rate, the average global temperature will increase by 1.5°C to 4.5°C by the end of this century. ...
The projected increase in global temperature due to greenhouse gas emissions is based on a combination of verified measurements and models that simulate the behavior of the Earth's climate system. While measurements of temperature, sea level rise, and other indicators provide concrete evidence of global warming, projections of future warming rely on sophisticated computer models that incorporate data on various factors like greenhouse gas concentrations, solar radiation, and other climatic forces.Is this temperature increase an estimate or a projection based upon verified measurements over a statistically valid time period?

What is the maximum average global temperature that is known across earths history? Is it true that the earth goes through warming and cooling cycles?
