As the name suggests, climate change is a change in the climatic conditions on the Earth. Several factors contribute towards this change since centuries. However, the more recent ones that are mainly a result of human activities are having a negative repercussion on the atmosphere.
Researchers continually observe the pattern to understand the past, present as well as the future climatic conditions. A record of the climate has been accumulated and is updated regularly based on the geological evidence to study the changes occurred. This evidence includes the records of flora and fauna, glacial and periglacial processes, records of sea levels, borehole temperature profiles and sediment layers among other things.
Here is a closer look at the causes and effects of climate change:
Causes of Climate Change
The factors that contribute towards climate change are:
- Solar Radiation
The energy emitted by the Sun that reaches the Earth and is carried further to different parts of the planet by winds and ocean currents is one of the main reasons for the climatic change.
- Human Activities
The new age technology is adding to the emission of carbon on the planet which in turn is having a negative impact on the climate.
Apart from this, the orbital variations, plate tectonics, and volcanic eruptions also cause changes in the climate.
Effects of Climate Change
- Impact on Forests and Wildlife
A number of species of plants and animals have gone extinct due to the change in the climatic conditions and many others are on the verge of going extinct. With the mass extinction of trees in certain regions, many forests are also diminishing.
- Impact on Water
Changes in the climatic conditions are also having a negative impact on the water system. It has resulted in the melting of glaciers and erratic rainfall patterns that in turn are leading to environmental imbalance.
It is important to take the climate change issue seriously and control human activities that are contributing towards this change.
