During the ice ages of the past 800,000 years and more, and further back to warmer times for 15 million years before then, Earthu2019s surface and oceans have warmed and cooled. The relationship between CO2 levels and temperature (with some variation) has been much the same in warmer and colder eras. With todayu2019s CO2 levels in the air, Earth then (say, 14 million years ago) was 5u00b0C hotter than the 20th century average. Visit: https://www.globalwarming-sowhat.com/heat/world

Past and Future Global Temperatures UNDERSTANDING KEY FACTORS
Introduction The Earth experienced gradual temperature changes throughout millions of years yet recent periods show the fastest temperature increase the planet has experienced. Listening to news reports about climate change and global warming does not reveal their specific effects on our planet. The analysis of historical temperature shifts alongside projections about upcoming changes helps us grasp the main importance of these events.
Temperature fluctuations Temperature fluctuations over extensive periods represent a normal natural process for Earth. Throughout history the planet experienced alternating intervals of ice ages and non-ice age periods which occurred thousands of years ago. The Earth experienced gradual shifts which nature created through volcanic activity along with Earth orbital variations and solar influence. The natural changes occurred during thousands of years whereas the current changes take only a few decades.
Recent years have been much hotter A warming trend emerged in the world during the late 1800s. The Earth has experienced more than 1 degree Celsius rise on average according to scientists. Small temperature fluctuations produce significant effects although the change in Celsius only reaches 1 degree.
People are causing most of the warming Lorem ipsum dolor sit amet, consectetur adipiscing elit. Curabitur a justo ut eros tristique pharetra quis ut leo. Maecenas fringilla consequat augue eget accumsan. Donec vel eros feugiat turpis ullamcorper ultricies. Nulla lectus arcu, sollicitudin eu ligula tincidunt, cursus imperdiet odio.
The future could be much hotter Continuing current patterns of operations could result in a dramatic 2 to 4 degree Fahrenheit temperature rise that would affect the Earth during this century. Past and future global temperatures, temperature increases up to 2-4 degrees Fahrenheit during this century will result in severe weather patterns while creating fiercer storms coupled with devastating effects People who live near the ocean risk sustaining house damage from increased water heights. Extremes of climate change may diminish food sources and drinking water availability in particular areas. Experts state that controlling temperature increase effectively should be a priority.
Conclusion The world experiences its fastest temperature increase at present and this change touches all populations regardless of their geographical location. Historical evidence demonstrates that Earth undergoes past and future global temperatures changes yet modern society possesses the capability to direct future transformations.
