Fine Particulate Matter
Fine Particulate Matter Fine particulate matter are microscopic particles suspended in the air, known as aerosols. PM10 includes particles smaller than 10 micrometers, and PM2.5 refers to those under 2.5 micrometers. These particles originate from human activities (e.g., industry, transport, agriculture) and natural sources (e.g., wildfires, volcanic eruptions) or form through chemical reactions in the…

Protected areas
Protected areas Protected areas are clearly designated geographical spaces that are managed for the long-term conservation of nature, biodiversity, and cultural heritage. These areas are set aside to prevent harmful human activities, ensuring the preservation of ecosystems, wildlife, and landscapes. They provide essential benefits such as safeguarding clean air and water, supporting biodiversity, and offering…

Net zero emissions
Net zero emissions Net zero emissions refers to the balance between the amount of greenhouse gases emitted and the amount removed from the atmosphere, resulting in no net increase in atmospheric GHG. Achieving net zero involves reducing emissions as much as possible through measures such as transitioning to renewable energy, improving energy efficiency, and adopting…

Greenhouse gas
Greenhouse gas Greenhouse gases (GHG) are those gaseous constituents of the atmosphere, both natural and anthropogenic, that absorb and emit radiation at specific wavelengths within the spectrum of terrestrial radiation emitted by the Earth’s surface, the atmosphere itself and by clouds. Water vapor (H2O), carbon dioxide (CO2), nitrous oxide (N2O), methane (CH4) and ozone (O3)…

Greenhouse effect
Greenhouse effect The greenhouse effect is a natural process that occurs when certain gases in the Earth’s atmosphere, known as greenhouse gases, trap heat from the sun. These gases allow sunlight to enter the atmosphere and reach the Earth’s surface. However, they also absorb and re-radiate infrared radiation emitted by the Earth, trapping heat in…

Global warming
Global warming Global warming refers to the long-term increase in Earth’s average surface temperature due to human activities, primarily due to the release of greenhouse gases into the atmosphere. These gases, such as carbon dioxide and methane, trap heat from the sun as a greenhouse effect, leading to a gradual rise in temperatures worldwide. This…

Climate Change
Climate Change Climate change refers to the long-term variations observed in weather conditions due to the warming of the Earth’s atmosphere. These variations include changes in temperature, precipitation, wind patterns and other aspects of the climate system. Although natural processes, such as the solar cycle or massive volcanic eruptions, can contribute to these changes, human…
