Climate Change

The Long-term changes in temperature and the weather patterns are also referred to as climate change. There are changes that could be natural and caused by variations in the solar cycle. However, since the 1800s, human activities have been the primary cause of climate change, owing primarily to the use of fossil fuels such as coal, oil, and gas.

The combustion of fossil fuels produces greenhouse gas emissions, which act like a blanket wrapped around the Earth, trapping heat from the sun and raising temperatures. Carbon dioxide and methane are two examples of greenhouse gas emissions that are causing climate change. These are caused by using gasoline to drive a car or coal to heat a building, for example. Clearing land and forests can also result in the release of carbon dioxide. The Garbage landfills are a major source of the methane emissions. Among the major emitters are energy, industry, transportation, buildings, agriculture, and land use.

What is a Climate Change?

Climate change refers to a long-term change in the average conditions of a region, such as temperature and rainfall. For example, glaciers covered much of the United States 20,000 years ago. Today’s climate is warmer and with fewer glaciers.

The Global climate changes refers to the long-term average changes across the entire planet. These include rising temperatures and precipitation changes, as well as the effects of global warming, such as: 

• Increasing sea levels
• Mountain glaciers are receding.
• Greenland, Antarctica, and the Arctic are melting at a faster rate than usual.
• The Changes in the blooming times of the flowers and plants.

Even before humans arrived on the scene, the Earth’s climate was constantly changing. However, scientists have recently noticed unusual changes. For example, over the last 150 years, the average temperature of the Earth has risen much faster than expected.

Basic effects of climate change

Human-caused increases in average global temperatures have a wide range of consequences for the planet, including more intense and frequent droughts and storms, melting glaciers and ice sheets, rising sea levels, warming oceans, and ocean acidification. 

Climate change is already having an impact on the environment, and people all over the world are feeling it. Changing weather patterns can destroy crops and lead to severe water shortages. Rising sea levels put low-lying islands and coastal cities at risk. Tropical and insect-borne diseases are spreading as their hosts move into previously inhospitable environments.

Climate change poses a significant threat to human societies’ health and well-being, particularly in communities that lack resources and are thus ill-equipped to deal with the effects of a warmer climate.

Causes of climate change

There are numerous factors that influence the Earth’s climate. However, scientists agree that human activity has caused the Earth to warm over the last 50 to 100 years.

Some gases in the Earth’s atmosphere prevent heat from escaping. This is known as the greenhouse effect. These gases keep the Earth warm in the same way that glass in a greenhouse keeps plants warm.

Human activities, such as the use of fossil fuels to power factories, automobiles, and buses, are altering the natural greenhouse effect. Because of these changes, the atmosphere traps more heat than it used to, resulting in a warmer Earth.

What effect does climate change have on food supply?

Climate change can affect farmers’ ability to grow crops as well as the infrastructure required to transport and store food supplies by increasing the frequency and intensity of droughts, floods, and storms. Changes in seasonal weather patterns, which farmers are accustomed to, also make planning plantings and harvests more difficult. Warming ocean temperatures are causing range shifts for fish and shellfish species, affecting fisheries.

Though plants require carbon dioxide to grow, higher levels of CO2 in the atmosphere are not always beneficial to agriculture. Researchers discovered that higher carbon dioxide levels result in crops with lower nutritional value.

What exactly is adaptation to climate change?

Climate adaptation entails preparing for the current and anticipated effects of climate change. It can be applied to habitats as well as societies and economies. Adaptation typically entails preparing for negative consequences (such as rising sea levels and more frequent and intense extreme weather), but it can also prepare communities to capitalise on climate change opportunities. Climate adaptations include shifting crop planting and harvesting patterns to match a new climatic zone, relocating homes away from the coast or building them on stilts, and planting trees in cities to reduce intense heat exacerbated by the urban heat island effect.

Nature-based adaptation is an important type of climate adaptation. The tree mentioned above is an example of a nature-based solution, as are green roofs that absorb stormwater and reduce temperatures, and living shorelines that can absorb storm surge during extreme weather events.
