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.
What is the biggest problem in climate change?
Climate change is already happening: temperatures are rising, drought and wild fires are starting to occur more frequently, rainfall patterns are shifting, glaciers and snow are melting and the global mean sea level is rising.
What is the main cause of climate change problems?
Human activity is the main cause of climate change. People burn fossil fuels and convert land from forests to agriculture. … Burning fossil fuels produces carbon dioxide, a greenhouse gas. It is called a greenhouse gas because it produces a “greenhouse effect”.
What are the 5 major factors that affect climate change?
- Latitude. It depends on how close or how far it is to the equator. …
- Ocean currents. Certain ocean currents have different temperatures. …
- Wind and air masses. Heated ground causes air to rise which results in lower air pressure. …
- Elevation. The higher up you are, the colder and drier it will be. …
What are the 4 main causes of climate change?
Causes for rising emissions
- Burning coal, oil and gas produces carbon dioxide and nitrous oxide.
- Cutting down forests (deforestation). …
- Increasing livestock farming. …
- Fertilisers containing nitrogen produce nitrous oxide emissions.
- Fluorinated gases are emitted from equipment and products that use these gases.
How bad is climate change 2021?
17 March: a study by the International Federation of Red Cross and Red Crescent Societies estimated that, globally between September 2020 and February 2021, 12.5 million people were displaced by adverse impacts of climate change, the annual average exceeding 20 million.
What are the biggest global problems?

What are some examples of climate change?
These include warming temperatures and changes in precipitation, as well as the effects of Earth’s warming, such as:
- 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.
What causes climate change for kids?
The primary cause is greenhouse gas emissions from cars, power plants and other human-made sources—rather than natural variations in climate. … Greenhouse gases act like a blanket, trapping the sun’s warmth near the earth’s surface, and affecting the planet’s climate system.
What are the 6 major controls of the climate of the world?
There are six major controls of the climate of an area. These factors are latitude, elevation, nearby water, ocean currents, topography, vegetation, and prevailing winds.
What are the two effects of climate change on the environment?
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 affects the climate?
The temperature characteristics of a region are influenced by natural factors such as latitude, elevation and the presence of ocean currents. The precipitation characteristics of a region are influenced by factors such as proximity to mountain ranges and prevailing winds.
