Climate is usually defined as the "average weather" in a place. It includes patterns of temperature, precipitation (rain or snow), humidity, wind and seasons. Climate patterns play a fundamental role in shaping natural ecosystems, and the human economies and cultures that depend on them. But the climate we’ve come to expect is not what it used to be, because the past is no longer a reliable predictor of the future. Global Warming & Climate Change - The New York Times. Climate.nasa. Climate change - Wikipedia. Climate change is a change in the statistical distribution of weather patterns when that change lasts for an extended period of time (i.e., decades to millions of years).
Climate change may refer to a change in average weather conditions, or in the time variation of weather around longer-term average conditions (i.e., more or fewer extreme weather events). Climate change is caused by factors such as biotic processes, variations in solar radiation received by Earth, plate tectonics, and volcanic eruptions. Certain human activities have also been identified as significant causes of recent climate change, often referred to as global warming. Terminology The most general definition of climate change is a change in the statistical properties (principally its mean and spread) of the climate system when considered over long periods of time, regardless of cause. Accordingly, fluctuations over periods shorter than a few decades, such as El Niño, do not represent climate change.
Security Check Required. Climate.nasa. EU Climate Policy - Stop Climate Change. The EU can and must be a climate leader EU leaders have agreed to a binding target of a 20% reduction of carbon emissions levels by 2020 compared to 1990 levels.
The EU is already on its way to achieving its climate target. The Greens/EFA group thus pushes the EU to increase its own domestic climate ambition and set itself a binding target of at least 30% by 2020. Untitled. Untitled.
