GLOBAL WARMING : A GLOBAL WARNING?

Global warming is defined as a rise in the average temperature of the Earth, particularly a long-term shift significant enough to induce climate change. Since 1900, the global average surface temperature has risen by more than a degree, and the rate of warming has nearly doubled the century-long average since 1970. Global warming refers to an increase in the average temperature of the Earth. Almost all experts examining the earth's climate record now agree that human actions, specifically the release of greenhouse gases from smokestacks, cars, and burning forests, are possibly the primary force behind the trend. The gases supplement the planet's natural greenhouse effect, allowing sunlight in but preventing part of the resulting heat from escaping into space. Many climate experts believe that if greenhouse gas emissions are not significantly reduced, the 21st century will see temperatures rise by 3 to 8 degrees, climatic patterns alter dramatically, ice sheets decrease, and sea levels rise by several feet.

With the possible exception of another world war, a massive asteroid, a deadly pandemic, or global warming may be the only major threats to our planet.

CAUSES:

The emission of greenhouse gases into the atmosphere, such as carbon dioxide, methane, and nitrous oxide, is the primary driver of global warming. The primary source of CO2 emissions in power plants. These power stations release significant volumes of CO2 from the combustion of fossil fuels for electricity generation.

The combustion of gasoline in automobile engines accounts for approximately 20% of carbon dioxide emissions into the environment. Buildings, both commercial and residential, contribute more to global warming pollution than automobiles and trucks. Building huge structures necessitate the use of a lot of fuel, which emits a lot of carbon dioxide into the environment. Methane is more than 20 times more effective than carbon dioxide in trapping heat in the atmosphere. Methane is generated from a variety of sources, including rice paddies, bovine farts, bog microbes, and the production of fossil fuels. The primary sources of nitrous oxide include the manufacturing of nylon and nitric acid, automobiles with catalytic converters, the usage of fertilisers in agriculture, and the combustion of organic materials.
Deforestation, which is caused by the chopping and burning of trees for residential and industrial use, is another driver of global warming.

Scientists all throughout the world are making predictions about the negative impacts of global warming and linking some of the events that have occurred in recent decades as an alarm of global warming. The average temperature of the Earth is rising as a result of global warming.

A rise in global temperatures can induce additional changes in the environment, such as rising sea levels and changing the amount and pattern of rainfall. These changes may increase the frequency and severity of catastrophic weather events such as floods, famines, heat waves, tornadoes, and twisters. Other implications might include greater or lower agricultural outputs, glacier melting, decreased summer stream flows, genus extinctions, and a shift in disease vector distributions. Many bird and animal species have already become extinct as a result of global warming. As a result of global warming, several new illnesses have recently appeared.

Many species are likely to die off or become extinct as sea temperatures rise, whilst other species that favour warmer waters will thrive. Coral reefs are predicted to die out as a result of global warming, which is one of the most concerning trends. Climate change is projected to produce irreversible changes in the ecology and animal behaviour. Birds are one of the species that will be impacted by climate change. Birds may find a more permanent home in northern portions of the Northern Hemisphere as a result of global warming.

Scientists warn that the tundra is at risk of melting owing to an increase in global warming pollution equal to the net quantity previously present in the earth's/atmosphere. Similarly, another team of scientists previously claimed that in a single year, Greenland saw 32 glacial earthquakes with magnitudes ranging from 4.6 to 5.1 on the Richter scale. This is a concerning indicator, indicating that a massive destabilization is currently taking place deep beneath the world's second-largest ice growth. If this ice melted and fell into the sea, it would raise global sea levels by 20 feet.

Every day brings more evidence that we are currently in the midst of a global emergency, a climate catastrophe that requires immediate action to drastically reduce carbon dioxide emissions globally to slow the earth's increasing temperatures and escape disaster.

It is difficult to attribute any individual incident to global warming, but studies show that human activities are raising the earth's temperature. Even if no new greenhouse gases were released after 2100, global warming and sea level would likely continue to increase for more than a millennium, since carbon dioxide has a long average atmospheric life cycle.

Various countries are making significant efforts to slow the rate of global warming. The Kyoto Protocol, signed by numerous governments to minimize emissions of various greenhouse gases, is one such initiative. In addition, various non-profit organizations are attempting to further the cause
