The climate of a region depends on many factors including the amount of sunlight it receives, its height above sea level, the shape of the land, and how close it is to oceans. Since the equator receives more sunlight than the poles, climate varies depending on its distance from the equator.
What causes climate variability?
Climate variability is the way aspects of climate (such as temperature and precipitation) differ from an average. Climate variability occurs due to natural and sometimes periodic changes in the circulation of the air and ocean, volcanic eruptions, and other factors.
What is varied climate?
Climate variability includes all the variations in the climate that last longer than individual weather events, whereas the term climate change only refers to those variations that persist for a longer period of time, typically decades or more. … The climate system also radiates energy to outer space.
Why is climate change happening and what are the causes?
Humans are increasingly influencing the climate and the earth’s temperature by burning fossil fuels, cutting down forests and farming livestock. This adds enormous amounts of greenhouse gases to those naturally occurring in the atmosphere, increasing the greenhouse effect and global warming.
How is climate change affecting the environment?
More frequent and intense drought, storms, heat waves, rising sea levels, melting glaciers and warming oceans can directly harm animals, destroy the places they live, and wreak havoc on people’s livelihoods and communities. As climate change worsens, dangerous weather events are becoming more frequent or severe.
Why do climate differs from place to place?
There are differences in climate around the world because of differing amounts of radiation received from the Sun at different parts of the Earth at different times of the year. More heat from the Sun is received near the equator than near the north and south poles where the angle of the Sun’s rays is lower.
What factors affect the climate?
There are lots of factors that influence our climate
- Elevation or Altitude effect climate. Normally, climatic conditions become colder as altitude increases. …
- Prevailing global wind patterns. …
- Topography. …
- Effects of Geography. …
- Surface of the Earth. …
- Climate change over time.
Why do you think the climate differs from place to place?
Climate varies from region to region. This variation is driven by the uneven distribution of solar heating, the individual responses of the atmosphere, oceans and land surface, the interactions be- tween these, and the physical characteristics of the regions.
Why is climate change so important?
It’s important that we understand how the climate is changing, so that we can prepare for the future. Studying the climate helps us predict how much rain the next winter might bring, or how far sea levels will rise due to warmer sea temperatures.
Why is climate change a concern?
Increased heat, drought and insect outbreaks, all linked to climate change, have increased wildfires. Declining water supplies, reduced agricultural yields, health impacts in cities due to heat, and flooding and erosion in coastal areas are additional concerns.
What are the 3 main natural causes of climate change?
The earth’s climate is influenced and changed through natural causes like volcanic eruptions, ocean currents, the Earth’s orbital changes, solar variations and internal variability.
How does climate change affect society?
Climate change is projected to increase the frequency and intensity of extreme weather events, such as heat waves, droughts, and floods. These changes are likely to increase losses to property and crops, and cause costly disruptions to society.
