The Modern Climate Change
Climate change includes both global warming driven by human-induced emissions of the greenhouse gases and the resulting large-scale shifts in weather patterns. Though there have been previous periods of climate change, humans have since the mid-20th century had an unprecedented impact on Earth’s climate system and have caused change on a global scale.
The largest driver of warning is the emission of gases that create a greenhouse effect, of which more than 90% are carbon dioxide and methane. Fossil fuel burning for energy consumption is the main sourse of these emissions, with additional contributions from agriculture, deforestation, and manufacturing. The human cause of climate change is not disputed by any scientific body of national or international standing. Temperature rise is accelerated or tempered by climate feedback, such as loss of sunlight-reflecting snow and ice over, increased water vapour and changes to land and ocean carbon sinks.
Temperature rise on land is about twice the global average increase, leading to desert expansion and more common heat waves and wildfire. Temperature rise is also amplified in the Artic, where it has contributed to melting permafrost, glacial retreat and sea ice loss. Warmer temperatures are increasing rates of evaporation, causing more intense storms and weather extremes. Climate change threatens people with food insecurity, water scarcity, flooding, infectious diseases, extreme heat, economic losses, and displacement. These impacts have led the World Health Organisation to call climate change the greatest threat to global health in the 21stcentury.
Effects of Global Warming
- More frequent and severe weather
- Higher temperatures
- Worsening’s of types of disasters, including storms, heat waves, floods, and droughts
- Higher death rates
- Dirtier air
- Higher wildlife extinction rates
- More acidic oceans
- Higher sea levels
Due to these facts and effects it is more crucial than ever to do your part to cut down your carbon foot print.
