Causes and effects of climate change have forced humans into finding better ways to live daily through actions such as recycling, consuming energy and reducing dependency of fossil fuels. There is a tremendous amount of evidence collected over the years by scientists that tell a story about how the Earth is changing. While such elements are fascinating and intriguing, it is also raising questions and concerns about global warming and climate change.
In particularly, evidence dating back thousands of years through different forms of human civilization show how such changes of the Earth have evolved. The following points offer brief insight on causes and effects contributing to climate change.
Climate Change Causes
- The Earth’s surface absorbs different types of gases and molecules that enter and exit its atmosphere. This includes radiation from sunlight. The emissions go in all directions helping to heat the Earth’s surface. In other words the Earth is covered in a blanket.
- The Earth has gases that prevent heat from escaping into the atmosphere. These gases contribute to changes in climate system development.
- Water vapors in the Earth’s atmosphere are part of greenhouse gases. Yet, these same vapors contribute to precipitation and cloud development on Earth.
- Carbon dioxide is another gas found to help heat the Earth’s surface. This element is important to land, fossil fuel burning and other natural processes of the Earth such as volcano eruption. Yet, humans help develop more of this gas and it is a contributing problem of climate change.
- Human activity on Earth contributes to changes in emission levels of the atmosphere. This includes burning fossil fuels and land use for agriculture.
Climate Change Effects
- Scientists say the average temperature of the Earth has increased by at least one degree in recent years. While this seems small experts believe activity on Earth has increased dramatically causing long-term Earth temperature changes.
- Parts of the world are seeing phenomenal change including shrinking of glaciers and ice thawing of lakes and rivers occurring sooner than expected. Animal and plant development has seen a shift and flowers and trees tend to bloom earlier or later depending on where they are located.
- Human activity will continue to encourage surface temperature of the Earth by as much as 10 degrees in the next century. This is a conclusion from more than 1,000 scientists from around the world.
- The cost of maintaining agriculture, ecosystems and infrastructures is expected to increase thanks to climate change. A number of companies, businesses and corporations have included elements of climate change into their annual budgets.
- Certain parts of the world experience warmer temperatures, heavy rains and rising sea levels. In other parts of the world problems with water supply, erosion, insect outbreaks and diseased trees (causing more to die off) are on the rise. Natural disasters such as wildfires, drought and tropical systems increase in magnitude. Some regions have seen their share of tropical systems and longer periods without rain.
