2. Natural Climate Changes Causes:

a. Greenhouse Gases: 

Greenhouse gases (GHGs) are central to the causes of climate change, playing a crucial role in the Earth’s natural greenhouse effect. While the greenhouse effect is essential for maintaining a habitable temperature on our planet, human activities have significantly amplified this process, leading to global warming. Here’s how greenhouse gases are involved in causing climate change:

The natural greenhouse effect is a process where certain gases in the Earth’s atmosphere, known as greenhouse gases, trap heat from the Sun. This trapped heat keeps the Earth’s surface warm enough to support life. Water vapour, carbon dioxide (CO2), methane (CH4), nitrous oxide (N2O), and ozone (O3) are some of the key greenhouse gases involved in this process.

Human activities, such as the burning of fossil fuels (coal, oil, and natural gas), deforestation, industrial processes, and agriculture, release significant amounts of greenhouse gases into the atmosphere.

d. Earth Orbits and Rotation:

The Earth’s orbits and rotation play a crucial role in influencing climate over long periods. Three primary orbital parameters, collectively known as Milankovitch cycles, contribute to variations in Earth’s atmosphere. These cycles have significant impacts on the distribution of solar radiation received by the Earth, influencing climate patterns over thousands to hundreds of thousands of years. 

3. Effect of Climate Change:

The effects of climate change reverberate across Earth, impacting ecosystems, societies, and wildlife. Rising temperatures intensify droughts, storms, and heatwaves, while melting glaciers contribute to rising sea levels. Earth faces the peril of altered landscapes and disrupted weather patterns. For humanity, climate change poses the single largest health threat, manifesting through air pollution, extreme weather events, and food insecurity. Displaced populations, mental health challenges, and increased hunger underscore the profound human toll. Wildlife faces altered food chains and habitat loss, with species at risk due to changing environments. Climate change stands as an urgent call to safeguard the interconnected well-being of Earth, man, and wildlife.

A. To Earth: More frequent and intense drought, storms, heat waves, rising sea levels, melting glaciers and warming oceans can directly harm animals, destroy the places they live, and wreak havoc on people’s livelihoods and communities.

B. To Humans: Climate change is the single biggest health threat facing humanity. Climate impacts are already harming health through air pollution, disease, extreme weather events, forced displacement, pressures on mental health, and increased hunger and poor nutrition in places where people cannot grow or find sufficient food.

C. To wildlife: Altered food chains: the effects of climate change on even the smallest species can threaten ecosystems. Increased sea ice melt and ocean acidification in the Antarctic are reducing krill populations, threatening the survival of whales, penguins, and seals that depend on krill as a primary food source.
