What is climate change?
Introduction
A change in global or regional climate patterns, in particular a change apparent from the mid to late 20th century onwards and attributed largely to the increased levels of atmospheric carbon dioxide produced by the use of fossil fuels.
Effects Of Climate Change
Effects
Rising sea levels
Shrinking mountain glaciers
Ice melting at a faster rate than usual in Greenland, Antarctica and the Arctic
Changes in flower and plant blooming times.

Causes Of Climate Change
Causes
There are lots of factors that contribute to Earth’s climate. However, scientists agree that Earth has been getting warmer in the past 50 to 100 years due to human activities.
Certain gases in Earth’s atmosphere block heat from escaping. This is called the greenhouse effect. These gases keep Earth warm like the glass in a greenhouse keeps plants warm.
Human activities — such as burning fuel to power factories, cars and buses — are changing the natural greenhouse. These changes cause the atmosphere to trap more heat than it used to, leading to a warmer Earth.
How Much Is Earth’s Climate Changing Right Now?
Some parts of Earth are warming faster than others. But on average, global air temperatures near Earth's surface have gone up about 2 degrees Fahrenheit in the past 100 years. In fact, the past five years have been the warmest five years in centuries.
Many people, including scientists, are concerned about this warming. As Earth’s climate continues to warm, the intensity and amount of rainfall during storms such as hurricanes is expected to increase. Droughts and heat waves are also expected to become more intense as the climate warms.
When the whole Earth’s temperature changes by one or two degrees, that change can have big impacts on the health of Earth's plants and animals, too.
How can we end climate change?
Solutions
Regreening can help us to do this! Recent studies show that nature-based solutions can contribute up to 37% of the carbon emission intake required to keep global warming below 2 degrees Celsius. Vegetation cause the sequestration of carbon, decreasing the amount of carbon in the atmosphere and subsequently reducing the greenhouse effect, ultimately leading to the mitigation of global warming. Vegetation also causes cooling of the soil, decreasing the evaporation of water from the soil leading to increased water availability for plants, animals and humans. In addition, greening stimulates the water cycle, causing increased rainfall and the retention of water in the soil. This increase in the soil moisture content makes the land available for agriculture again, producing food and income for the local communities.
