2、USES OF GLOBAL WARMINGGreenhouse gas emissionsThe burning of fossil fuels such as coal,oil,and natural gas releases carbon dioxide(CO2)and other greenhouse gases into the atmosphere.These gases trap heat and contribute to the greenhouse effect,leading to global warming.CAUSES OF GLOBAL WARMINGDefore

3、stationThe cutting down of forests for agriculture,logging,and urbanization reduces the Earths ability to absorb CO2 through photosynthesis.This results in higher CO2 levels in the atmosphere,contributing to global warming.CAUSES OF GLOBAL WARMINGIndustrialization and urbanizationThe rapid growth of

4、 industries and cities increases the demand for energy,leading to increased burning of fossil fuels.This releases more greenhouse gases into the atmosphere,intensifying the greenhouse effect and causing global warming.Causes of Global WarmingLand use changes Agricultural practices Industrial and hou

7、 WARMINGIndustrial and household wasteImproper disposal and management of waste,especially in landfills,can generate methane emissions.Methane is a potent greenhouse gas that contributes to global warming when released into the atmosphere.Causes of Global WarmingPopulation growth Increased energy co

8、nsumption Natural factorsCAUSES OF GLOBAL WARMINGIncreased energy consumptionThe rising demand for electricity and energy-intensive products results in increased fossil fuel combustion.This increases the release of greenhouse gases,exacerbating global warming.CAUSES OF GLOBAL WARMINGPopulation growt

9、hThe growing global population leads to increased energy consumption,deforestation,and agricultural activities.These factors collectively contribute to higher greenhouse gas emissions and the acceleration of global warming.Causes of Global WarmingFeedback loopsCAUSES OF GLOBAL WARMINGFeedback loopsG

10、lobal warming can trigger feedback loops that further amplify the warming process.For example,as temperatures rise,the melting of polar ice caps reduces the Earths albedo,leading to more heat absorption and further warming.IMPACTS OF GLOBAL WARMING2Impacts of Global WarmingExtreme weather events Ris

11、ing sea levels Disruption of ecosystemsIMPACTS OF GLOBAL WARMINGRising sea levelsWith the increase in global temperatures,the polar ice caps and glaciers are melting at an accelerated rate.This leads to a rise in sea levels,posing a significant threat to coastal regions and low-lying islands.As sea

12、levels continue to rise,it can result in the displacement of millions of people,loss of habitats,and increased coastal erosion.Impacts of Global WarmingEconomic consequences Health impacts International security risksIMPACTS OF GLOBAL WARMINGHealth impactsGlobal warming has significant implications

13、for human health.The increase in temperatures can lead to heat-related illnesses and deaths,particularly among vulnerable populations such as the elderly and young children.It can also worsen air quality,leading to respiratory problems and an increase in the prevalence of diseases like asthma.Change

14、s in precipitation patterns can also affect water quality and contribute to the spread of waterborne diseases.IMPACTS OF GLOBAL WARMINGEconomic consequencesThe impacts of global warming have far-reaching economic consequences.Extreme weather events can cause significant damage to infrastructure,agri

15、culture,and industries,resulting in substantial financial losses.The need for adaptation and mitigation measures to address the effects of global warming also requires substantial investments.Additionally,the loss of coastal areas and disruption of ecosystems can affect tourism,fisheries,and other s

16、ectors that rely on natural resources.IMPACTS OF GLOBAL WARMINGInternational security risksGlobal warming poses risks to international security.The competition for resources,particularly water and arable land,can lead to conflicts and political instability.The displacement of people due to rising se

17、a levels and extreme weather events can also contribute to social unrest and migration pressures.Additionally,the impacts of global warming can exacerbate existing social and economic inequalities,further straining international relations.Impacts of Global WarmingMitigation and adaptation measuresIM

18、PACTS OF GLOBAL WARMINGMitigation and adaptation measuresTo address the impacts of global warming,mitigation and adaptation measures are necessary.Mitigation involves reducing greenhouse gas emissions to limit further warming,while adaptation focuses on building resilience and adapting to the change

19、s that are already occurring.Mitigation measures include transitioning to clean and renewable energy sources,improving energy efficiency,and implementing sustainable land-use practices.Adaptation measures include investing in infrastructure that can withstand extreme weather events,implementing earl
