According to NOAA and NASA data, the Earth's average surface temperature has increased by about 1.2 to 1.4ºF in the last 100 years.
In 2006, the world emitted over 28 billion metric tons of CO2. Thailand was part of that by emitting 200 million metric tons of CO2.
If greenhouse gases continue to increase, climate models predict that the average temperature at the Earth's surface could increase from 1.8 to 4ºC (3.2 to 7.2ºF) above 1990 levels by the end of this century.
Scientists have observed that some changes are already occurring. Observed effects include sea level rise, shrinking glaciers, changes in the range and distribution of plants and animals, trees blooming earlier, lengthening of growing seasons, ice on rivers and lakes freezing later and breaking up earlier, and thawing of permafrost.
Scientists are working to better understand future climate change and how the effects will vary by region and over time.
