The dangers of climate change

The changes in climate are not uniform across the Earth. In particular, most land areas have warmed faster than most ocean areas, and the Arctic is warming faster than most other regions.[6] Among the effects of climate change on oceans are an increase of ocean temperatures, a rise in sea level from ocean warming and ice sheet melting, increased ocean stratification, and changes to ocean currents including a weakening of the Atlantic meridional overturning circulation.[3]: 10  Carbon dioxide from the atmosphere is acidifiying the ocean

Recent warming has strongly affected natural biological systems.[8] It has degraded land by raising temperatures, drying soils and increasing wildfire risk.[9]: 9  Species worldwide are migrating poleward to colder areas. On land, many species move to higher ground, whereas marine species seek colder water at greater depths.[10] At 2 °C (3.6 °F) of warming, around 10% of species on land would become critically endangered.[11]: 259 

Food security and access to fresh water are at risk due to rising temperatures. Climate change has profound impacts on human health, directly via heat stress and indirectly via the spread of infectious diseases. The vulnerability and exposure of humans to climate change varies by economic sector and by country. Wealthy industrialised countries, which have emitted the most CO2, have more resources and so are the least vulnerable to global warming.[12] Economic sectors affected include agriculture, fisheries, forestry, energy, insurance, and tourism. Some groups may be particularly at risk from climate change, such as the poor, women, children and indigenous peoples.[13][14] Climate change can lead to displacement and changes in migration flows.[15].Global warming or climate change has today become a major threat to the mankind. The Earth’s temperature is on the rise and there are various reasons for it such as greenhouse gases emanating from carbon dioxide (CO2) emissions, burning of fossil fuels or deforestation.


Impact of Greenhouse Gases

The rise in the levels of carbon dioxide (CO2) leads to substantial increase in temperature. It is because CO2 remains concentrated in the atmosphere for even hundreds of years. Due to activities like fossil fuel combustion for electricity generation, transportation, and heating, human beings have contributed to increase in the CO2 concentration in the atmosphere.


Global Warming: A Gradual Phenomenon

Recent years have been unusually warm, causing worldwide concern. But the fact is that the increase in carbon dioxide actually began in 1800, due to the deforestation of a large chunk of North-eastern American, besides forested parts of the world. The things became worse with emissions in the wake of the industrial revolution, leading to increase in carbon dioxide level by 1900.


Cause of Concern

According to the Intergovernmental Panel on Climate Change (IPCC), global temperature is likely to rise by about 1-3.5 Celsius by the year 2100. It has also suggested that the climate might warm by as much as 10 degrees Fahrenheit over the next 100 years.


Impact of Global Warming

The sea levels are constantly rising as fresh water marshlands, low-lying cities, and islands have been inundated with seawater.

There have been changes in rainfall patterns, leading to droughts and fires in some areas, and flooding in other areas.

Ice caps are constantly melting posing a threat to polar bears as their feeding season stands reduced.

Glaciers are gradually melting.

Animal populations are gradually vanishing as there has been a widespread loss of their habitat.Global warming or climate change has today become a major threat to the mankind.
