The impact of climate change and human activities on desertification are exemplified in the Sahel region of Africa. The region is characterized by a dry hot climate, high temperatures and low rainfall (100–600 mm per year). [44] So, droughts are the rule in the Sahel region. [45]
Some climate change effects: wildfire caused by heat and dryness, bleached coral caused by ocean acidification and heating, environmental migration caused by desertification, and coastal flooding caused by storms and sea level rise. Effects of climate change are well documented and growing for Earth's natural environment and human societies. Changes to the climate system include an overall ...
The effects of climate change vary in timing and location. Up until now the Arctic has warmed faster than most other regions due to climate change feedbacks. [164] Surface air temperatures over land have also increased at about twice the rate they do over the ocean, causing intense heat waves.
For instance, it might be difficult to tell if desertification or desert expansion is the result of climate change or human activity. [19] Desertification in Africa is exacerbated by human factors such as deforestation, overgrazing, and unsustainable farming methods such as monoculture and excessive use of chemical fertilizers.
Climate change can also be used more broadly to include changes to the climate that have happened throughout Earth's history. [32] Global warming—used as early as 1975 [33] —became the more popular term after NASA climate scientist James Hansen used it in his 1988 testimony in the U.S. Senate. [34] Since the 2000s, climate change has ...
Of particular concern is how climate change and global warming caused by anthropogenic, or human-made releases of greenhouse gases, most notably carbon dioxide, can act interactively and have adverse effects upon the planet, its natural environment and humans' existence. It is clear the planet is warming, and warming rapidly.
NEW YORK (AP) — For decades, scientists warned that continued burning of oil, gas, and coal would have devastating climate impacts. Those impacts are being felt around the world. Climate change is driving extreme weather. By all accounts, the last few years have been brutal for the climate — and for the humans and other living things within it.
Deforestation is a primary contributor to climate change, [1] [2] and climate change affects the health of forests. [3] Land use change , especially in the form of deforestation, is the second largest source of carbon dioxide emissions from human activities, after the burning of fossil fuels .
