One of the major and the most obvious consequences of climate change is the increase in temperature all over the world.According to the NOAA (National Oceanic & Atmospheric Administration), the average increase in temperature is about 1.4 Fahrenheit in the last 100 years.
Studies have suggested that climate change could be a bigger threat than habitat destruction for the global biodiversity.
There are multiple approaches and thus a great variability in projections which makes it difficult to get a clear idea of the global climate change.
Human activity and climate change Several human activities have a large impact on climate change as they cause a change in the atmosphere of the Earth by increasing greenhouse gasses.
Some contributors are the burning of fossil fuels and the use of aerosols.
The atmosphere is something that is around us everyday, but do we really think about the changes that occur in it.
It isn't that we just aren't paying attention, but more of the fact that it is hard to notice slight changes over long periods of time.
Both aerosols and greenhouse gasses result in the altering of solar radiation and infrared radiation.
This, in turn, distorts the energy balance of the Earth, thus leading to excess heating or cooling of the planet.
While the climate has always been changing throughout the history of earth and species have changed accordingly, now we are facing a rapid climate change and this affects the ability of the species to adapt. The rapid change in climate and the resulting accelerating loss of biodiversity can pose human security issues as there can be changes in the food chain and water sources.
Some medicines might become harder to obtain because the fauna from which the chemicals are derived might disappear.
