Earth is getting hotter.

Since 1900, the average surface air temperature has risen 1.8 degrees Fahrenheit (1 degree Celsius). The steepest rise began in the 1970s and continues today.

We know this warming is happening because we have measurements of temperature from weather stations. In some places, recorded temperature measurements go back to the 1880s. Estimates of temperature changes in the further past are made from tree rings and ice cores. Today, surface temperatures are monitored at thousands of places, over both land and oceans.

An increase of 1.8 degrees Fahrenheit may not sound like a lot. On average, Earth is only 7 to 9 degrees Fahrenheit warmer today than it was during the last ice age. The recent increase in average temperature of only a couple degrees is already leading to global changes in precipitation, snow and ice extent, and extreme weather, such as heavy rains, heat waves, and severe storms.

Today, Earth is warming at a much faster rate than it warmed over the 7,000 years since the last ice age. If the current rate of warming isn’t slowed, Earth’s temperature is on track to increase by an additional 7 degrees Fahrenheit or more by the year 2100. That means that Earth will get hotter over the course of a few decades rather than over a few thousand years.
