Climate change describes a change in the typical weather for a region — such as high and low temperatures and amount of rainfall — over a long period of time. Scientists have observed that, overall, Earth is warming. In fact, many of the warmest years on record have happened in the past 20 years.
What Is Climate Change? Climate change refers to long-term shifts in temperatures and weather patterns. Such shifts can be natural, due to changes in the sun's activity or large
Climate change is the long-term alteration of temperature and typical weather patterns in a place. Climate change could refer to a particular location or the planet as a whole. Climate change may cause weather patterns to be less predictable. These unexpected weather patterns can make it difficult to maintain and grow crops in regions that rely
Introduction. Climate change refers to the shift in the Earth's usual weather conditions over many years. Our world has been getting hotter due to things humans are doing, like burning
Effects of global warming. The signs of global warming are everywhere, and are more complex than just climbing temperatures. 2:49. CAUSES AND EFFECTS OF CLIMATE CHANGE. What causes climate
Climate change is the long-term shift in the Earth's average temperatures and weather conditions. The world is now about 1.1C warmer than in the late 19th Century. Are
1. Scientific information taken from natural sources (such as ice cores, rocks, and tree rings) and from modern equipment (like satellites and instruments) all show the signs of a changing climate. From global temperature rise to melting ice sheets, the evidence of a warming planet abounds. En español.
Climate change is a long-term change in the average weather patterns that have come to define Earth's local, regional and global climates. These changes have a broad range of observed effects that are synonymous with the term.
