 Global warming refers to the long-term trend of increasing average global temperatures,
primarily caused by the release of greenhouse gases.
 By human activities such as burning fossil fuels, deforestation, and industrial processes.
 These greenhouse gases trap heat from the sun within the Earth's atmosphere, increasing the
planet’s overall temperature.

 The most common greenhouse gases include carbon
dioxide (CO2), methane (CH4), nitrous oxide (N2O), and
fluorinated gases.
 Human activities such as burning fossil fuels,
deforestation, and agriculture have increased the
concentration of greenhouse gases in the atmosphere,
leading to global warming and climate change.
 The effects of climate change include rising temperatures,
sea level rise, more frequent extreme weather events, and
changes in precipitation patterns, among others.

The basic mechanism of global warming is the greenhouse effect:

 Rising sea levels caused by the melting of ice caps and glaciers, which can lead to flooding of
low-lying areas, displacement of people, and loss of habitats for plants and animals.
 Changes in precipitation patterns, can affect agriculture, water supply, and biodiversity. Spread
of diseases and pests, as warmer temperatures create favorable conditions for their survival
and proliferation.
 Economic impacts, such as reduced productivity in agriculture, tourism, and other sectors, as
well as increased costs for adaptation and mitigation measures.

 There are currently at least 10,000 viruses “circulating silently” among wild mammals that
have the capacity to cross over into humans, mostly in the depths of tropical forests.
 As rising temperatures force those mammals to abandon their native habitats, they will meet
other species for the first time
 Creating at least 15,000 new instances of viruses jumping between animals by 2070, according
to a study published in the journal Nature.

 Promote sustainable land-use practices: This includes protecting forests, promoting
sustainable agriculture, and reducing deforestation and land-use change.
 Adopt low-carbon transportation options: This includes using public transportation, electric
vehicles, and active transportation (walking, biking).
 Promote sustainable consumption and waste reduction: This includes reducing food waste,
recycling, and reducing consumption of products with high carbon footprints.
 Implement carbon pricing policies: This includes carbon taxes or cap-and-trade systems that
create financial incentives for reducing greenhouse gas emissions.
 Support international climate action: This includes cooperation between nations to reduce
emissions, support for clean energy technology transfer, and climate finance for adaptation
and mitigation measures.
