Difference between Climate Change and Global Warming

Natural and Unnatural Changes

Climate Change refers to the set of alterations in the terrestrial climate that can affect all climatic parameters (rainfall, temperature, cloudiness, etc.). The climate has never been static, but throughout the history of the Earth, there have been various climatic changes caused by natural causes.

Global Warming is defined as the elevation of the average temperature of the earth's atmosphere, oceans and land masses (islands and continents).

Scientists consider that the Earth has been facing a period of rapid warming for several decades, attributed to human activities, caused by the atmospheric increase in the levels of gases that retain heat, called greenhouse gases.

Greenhouse gases retain radiant energy (heat), provided by the Sun to Earth, in a process called the greenhouse effect. These gases have a natural origin and without them the planet would be too cold to support life as we know it.

Since the beginning of the Industrial Revolution in the middle of the 18th century, the activities of human beings have added more and more gases of this type to the atmosphere.

Levels of carbon dioxide, a powerful greenhouse gas, have risen since 1750, primarily from the use of fossil fuels such as coal, oil, and natural gas. Thus, the atmosphere acts as a thicker blanket that absorbs more heat.




Waste Management in COVID-19 Pandemic

COVID-19 created additional challenges for waste management in developing countries.

In a UN publication (12-08-2020), improper handling of medical waste can have serious consequences for public health and a significant impact on the environment. Proper management of this waste, in addition to urban solid waste and other growing waste streams, such as electronic waste, construction and demolition waste and industrial waste, is therefore a fundamental part of protecting the environment and health.

The importance of proper healthcare waste management has received more attention with the COVID-19 pandemic, only discovered in late 2019.

The risks and challenges associated with waste management in times of the COVID-19 pandemic can be summarized and classified as follows:
