Essay On Geography And Human Geography

How do human geography and physical geography overlap? Steven Grade 9

Human geography and physical geography are not like each other, human geography are focus to the formation and development of regional structure of human social activities, but physical geography are focus to The natural environment or its components. But they also have the relationship. Here are some example of the human geography can change by physical geography reason.

First, Sea level rise is a problem human need to face. Sea level rise is a global sea level rise caused by global warming, the melting of polar glaciers, and the thermal expansion of the upper layer of sea water. Studies have indicated that the global sea level has

Although the increase of near-surface atmospheric temperature is the measure of global warming often reported in the popular press, most of the additional energy stored in the climate system since 1970 has gone into the oceans. The rest has melted ice and warmed the continents and atmosphere. Many of the observed changes since the 1950s are unprecedented over tens to thousands of years. Future climate change and associated impacts will differ from region to region around the globe. Anticipated effects include warming global temperature, rising sea levels, changing precipitation, and expansion of deserts in the subtropics. Warming is expected to be greater over land than over the oceans and greatest in the Arctic, with the continuing retreat of glaciers, permafrost and sea ice. Other likely changes include more frequent extreme weather events including heat waves, droughts, heavy rainfall with floods and heavy snowfall; ocean acidification; and species extinctions due to shifting temperature regimes. Effects significant to humans include the threat to food security from decreasing crop yields and the abandonment of populated areas due to rising sea levels. Because the climate system has a large "inertia" and CO2 will stay in the atmosphere for a
