Global Warming Affecting The Planet And Inhabitants.

In ancient times, people suspected that the climate of a region could change over a period of time. The scientific study of climate change began in the early 19th century. In the late 19th century, scientists found evidence that human emission of greenhouse gases could change the climate. In the beginning, climate change was not taken very seriously. Opinions about it changed in recent times because climate changes became very evident primarily due to burning fossil fuels that emit carbon dioxide (CO2), methane and other greenhouse gases in the atmosphere.

Global warming is measurably affecting the planet. As the name suggests, one of the most instantaneous and evident effects of global warming is the increase in temperatures around the world. The average temperature on our planet has increased by one-degree Celsius in the last 100 years. One degree Celsius may seem like an insignificant number but, even a slight rise in average temperature is enough to cause a drastic change to our planet.

Outrageous climate changes are one of the major impacts of global warming. While encountering some of the hottest summers on record, the planet has also been experiencing harsher winters. Scientists project that extreme climate changes such as heatwaves, droughts, blizzards, and rainstorms will keep on happening all the more regularly and with more intensity because of global warming. Also, high levels of greenhouse gases are likely to remain in the atmosphere for a long time which is why the climate changes will last longer and keep worsening.

One of the most dramatic effects of global warming is ice melts. North America, Europe, Asia have all experienced a less snow cover over the last couple of decades. Studies show that there is now 10% less permanently frozen ground than there was in the early 1900s. The thawing of ice may cause landslides or sudden land collapses. It can also release long-buried microbes of deadly diseases into the atmosphere. Glaciers melting is an obvious effect of global warming as well. Some glaciers have retreated up to 15 times as much as they would have without global warming.

As the ice melts, the seas levels rise. Global sea levels have risen about 8 inches since 1870 and are expected to keep rising in the years to come. If the situation continues, the coastal areas will be flooded. Ocean level isn't the only thing changing for the seas because of global warming. As levels of CO2 increase, the seas absorb a portion of that gas, which increases the acidity of seawater. If the ocean acidification continues, coral reefs will become extremely rare and life of the sea creatures will be hampered.

The impacts of global warming on the Earth's biological systems are significant and widespread. Numerous types of plants and creatures are as of now moving their habitat northward or to higher altitudes because of increasing temperatures. And the number of animals whose natural habitat requires low temperatures is declining due to global warming. Migratory birds and insects are also arriving at their feeding and nesting grounds several days or weeks earlier than they did in the 20th century. Warmer temperatures all over the globe will also lead to an increase in the number of disease-causing pathogens that were earlier found only in tropical and sub-tropical areas. If left unchecked, global warming may lead to the disappearance of the majority of plants and animal species on the planet.

As dramatic as the impacts of climate change are expected to be on the natural world, the anticipated changes to human society might be significantly more devastating. Agriculture may have to deal with a crippling blow due to growing seasons, impacts of drought, severe weather, snow melt, groundwater levels, loss of land and livestock shortage. Loss of food security may create havoc in the society causing riots, famines and civil unrest worldwide. An increase in temperature may also lead to an increase in various diseases.

Global warming is a real and serious issue. And knowing how it will affect the planet and our lives, we need to act promptly to curb its effects.
