What is climate change? The definition, causes and effects

The potential future effects of global climate change include more frequent wildfires, longer periods of drought in some regions and an increase in the number, duration and intensity of tropical storms. Global climate change has already had observable effects on the environment. Glaciers have shrunk, ice on rivers and lakes is breaking up earlier, plant and animal ranges have shifted and trees are flowering sooner. Effects that scientists had predicted in the past would result from global climate change are now occurring: loss of sea ice, accelerated sea level rise and longer, more intense heat waves. Scientists have high confidence that global temperatures will continue to rise for decades to come, largely due to greenhouse gases produced by human activities.

Climate change is the catch-all term for the shift in worldwide weather phenomena associated with an increase in global average temperatures. It's real and temperatures have been going up around the world for many decades. Reliable temperature records began in and our world is now about one degree Celcius hotter than it was in the period between and — commonly referred to as the "pre-industrial" average.


This study reviews the causes and effects of climate change on agriculture in Africa. The main interests are findings concerning the present and potential impacts.

Climate change includes both global warming driven by human emissions of greenhouse gases and the resulting large-scale shifts in weather patterns. Though there have been previous periods of climatic change , since the midth century humans have had an unprecedented impact on Earth's climate system and caused change on a global scale. Temperature rise on land is about twice the global average increase, leading to desert expansion and more common heat waves and wildfires. These impacts have led the World Health Organization to call climate change the greatest threat to global health in the 21st century.

Global warming

Jump to navigation. And yes, it's really happening. Over the past 50 years, the average global temperature has increased at the fastest rate in recorded history.

What is climate change? Is it the same as global warming? What are its main causes and consequences? Is it a lie? Find everything about climate change bel ow! Climate change is the global phenomenon of climate transformation characterized by the changes in the usual climate of the planet regarding temperature, precipitation, and wind that are especially caused by human activities.

Sparser rainfall leads to desertification that harms agriculture and can displace populations. Shown: Telly, Mali.

Global warming , the phenomenon of increasing average air temperatures near the surface of Earth over the past one to two centuries. Increases in greenhouse gases —i. Continued global warming is expected to impact everything from energy use to water availability to crop productivity throughout the world. Poor countries and communities with limited abilities to adapt to these changes are expected to suffer disproportionately. Global warming is already being associated with increases in the incidence of severe and extreme weather, heavy flooding , and wildfires —phenomena that threaten homes, dams, transportation networks, and other facets of human infrastructure. Temperature increases related to global warming have been the most pronounced at the poles, where they often make the difference between frozen and melted ice.

Global climate change has typically occurred very slowly over thousands or millions of years. However, research shows that the current climate is changing more rapidly than shown in geological records. During the last ice age, the British Isles had many glaciers like the example above, located in present-day Iceland. The energy output of the Sun is not constant, it varies over time and this has an impact on our climate. The period between these changes happen over 10s of s of years precession and axial tilt to more than s of s of years eccentricity.
