The climate where you live is called regional climate. Global climate is a description of the climate of a planet as a whole, with all the regional differences averaged.

Over more than a century, global average temperature warmed 1.5°F (0.8°C). Learn the science of why this has happened, and what the future hold.

Help the Joules family make choices that keep their greenhouse gas emissions low.
Factors that have the power to change global climate can be natural, like volcanic eruptions and changes in solar energy, or caused by humans, like the addition of greenhouse gases to the atmosphere.
co2

Energy from the Sun that makes its way to Earth can have trouble finding its way back out to space. The greenhouse effect causes some of this energy to be waylaid in the atmosphere, absorbed and released by greenhouse gases.

Vector-borne diseases are transmitted typically by the bite of an infected arthropod. Climate plays an important role in the seasonal pattern or temporal distribution of diseases that are carried and transmitted through vectors because the vector animals often thrive in particular climate conditions.
El Nino
Learn how the El Niño-Southern Oscillation (ENSO) climate fluctuation affects weather around the world.
Water moves from place to place through the water cycle, which is changing as climate changes. Learn how the water cycle is changing as global temperatures rise.

Warmer conditions are having an impact on our planet. The world's surface air temperature warmed 0.6° C (1.1°F) on average during the last century. This may not sound like very much change, but it is.
