How Geography and Climate Change Are Connected in Today’s World?

Climate change is one of the greatest challenges of the 21st century globally, impacting ecosystems, economies and communities all over the world. Climate change can be conceptualised as an increase in temperature and extreme weather events; however, understanding the causes and impacts of climate change depends greatly on the geographical location.

Geography can provide explanations for the variation in the impact of climate change on various regions and natural and human systems interactions with the environment. Linking geography to climate change is fundamental in creating solutions to this problem and planning for future environmental issues.

 Understanding Geography’s Role in Climate Change

Geography is the study of the physical features, environments and human activities of the earth. It explores interactions between humans and their environment, and the effects of natural systems on human life.

In regard to climate change, geography explains:

 Regional climate patterns

 Population distribution

 Natural resource use

 Land-use changes

 Environmental vulnerability

Geographers can use these factors to work out which parts of the world are most at risk and suggest ways of adapting and mitigating.

 Geography and Climate.Geography and the effect on the climate.

Local and global climates are influenced by different geographic features.

 Latitude

Equatorial regions are closer to the Sun, and therefore warmer, while the poleward regions are colder.

 Elevation

Cool climates may occur in mountainous areas, compared to adjacent lowland areas. Rainfall can also be affected by higher elevations.

 Water Bodies, Ocean

Wetlands modulate temperature and affect weather. Coastal climates may be less extreme (harsher) than inland climates.

 Landforms

Wind, precipitation, and temperature are influenced by mountains, valleys and plains.

The geographic factors are what help to determine the effects of climate change to specific sites.

 Climate change affects various geographic regions in different ways.

Not all regions of the world are equally impacted by climate change. The severity and type of impacts are greatly influenced by geography.

 Coastal Areas

Sea level is a threat to coastal communities in the following ways:

 Increased flooding

 Shoreline erosion

 Infiltration of saltwater into fresh water supplies

 Polar Regions

In the Arctic and Antarctic, the temperature is increasing more rapidly than in many other regions, causing:

 Melting ice sheets

 Loss of habitat for wildlife.

 Sea level rising.

 Dry and Arid Regions.

There are some drought prone areas with a longer duration of dry spells and water scarcity, which are impacting agricultural activities and livelihoods.

 Tropical Regions

In many tropical areas, storms are more intense, wetter and more likely to flood.

 Human Geography and Climate Change.

Human activities are one of key factors affecting climate change. Human geography focuses on the impact of population, industry and urban development on the environment.

Key factors include:

 Urbanization

As cities expand, their energy uses and GHG emissions tend to rise.

 Deforestation

Clear cutting the forests removes carbon dioxide from the ground to be held in the atmosphere.

 Industrial Activity

Global emissions are high due to the contribution from factories, transportation systems and energy production.

 Agricultural Practices

The use of land, water resources and the emissions of Greenhouse Gases (GHGs) can be affected by large scale farming.

These human factors can help in creating more sustainable solutions for the policymakers.

 Geographical inequality and climate change.Geographical inequality and climate change.

An essential component of climate geography is the understanding that certain communities are more vulnerable than others.

The vulnerable populations may be the following:

 Coastal communities

 Low-income regions

 Small island nations

 Areas where agriculture is a major activity

Geographic planning is particularly important for such communities that may have limited resources to deal with the changes in their environment.

 The significance of geographical work.

Geographers use maps, satellite images and geographic information systems (GIS) to examine changes to the environment.

These technologies help:

 Track climate trends

 Monitor land-use changes

 Predict natural disasters

 Support environmental planning
