Climate Change: What Is It and Why Does It Happen?

Climate change is defined as a change in the statistical distribution of weather patterns that continues over time. Climate change may refer to the change in average weather conditions. climate change has already had observable effects on the environment. Glaciers have shrunk, ice on rivers and lakes is breaking up earlier, plant and animal ranges have shifted, and trees are flowering sooner. Effects that researchers had predicted in the past would result from global climate change are now occurring loss of sea ice, accelerated sea level rise and longer, more intense heat waves.

Why Climate Changes?

There are two reasons of climate Changes

1. Natural Reasons of Climate Changes

2. Anthropogenic Reasons of Climate Changes

1. Natural Reasons of Climate Changes

Natural factor which influences Climate change have remained constant for centuries. Since 1750, the average amount of energy coming from the sun either remained constant or increased slightly. If the warming were caused by a more active sun, then scientists would expect to see warmer temperatures in all layers of the atmosphere. Instead, they have observed a cooling in the upper atmosphere, and a warming at the surface and in the lower parts of the atmosphere. That’s because greenhouse gases are trapping heat in the lower atmosphere. 

2. Anthropogenic Reasons of Climate Changes

Anthropogenic activities the most dominant with an ever-increasing trend since the industrial revolution of 1940s. Population growth in developing countries, which make about 70% of the comity of nations, has been too high putting an increased pressure on fixed natural resources and the compensation of increased demand for food and shelter through better socioeconomic conditions. Anthropogenic activities, particularly those associated with fossil fuel use, deforestation, and industrial processes, are the dominant drivers of modern climate change. These activities have disrupted Earth’s delicate balance, causing a rapid rise in global temperatures and widespread environmental impacts. Addressing these causes requires urgent and coordinated action, including transitioning to renewable energy, improving agricultural practices, and implementing sustainable urban development. Only through collective efforts can humanity mitigate the effects of climate change and secure a sustainable future. Researcher has high confidence that global temperatures will continue to rise for decades to come, largely due to greenhouse gases produced by human activities.
