Carbon-Di-Oxide In Atmosphere And Its Impact On Earth In Last 100 Years

 The levels of carbon dioxide (CO2) in the Earth's atmosphere have been increasing at an alarming rate over the past century, primarily due to human activities such as the burning of fossil fuels, deforestation, and industrial processes. This increase in CO2 has had a significant impact on the Earth's climate, leading to a phenomenon known as global warming. In this essay, we will discuss the effects of increased CO2 in the atmosphere over the past 100 years.

The first effect of increased CO2 in the atmosphere is global warming. CO2 is one of the primary greenhouse gases, which means that it traps heat from the sun and warms the Earth's atmosphere. Since the beginning of the industrial revolution, the concentration of CO2 in the atmosphere has increased by more than 40%, from around 280 parts per million (ppm) to over 400 ppm. This increase in CO2 has caused the Earth's temperature to rise by about 1 degree Celsius (1.8 degrees Fahrenheit) since the late 19th century. The warming trend has accelerated in recent decades, with the 10 warmest years on record occurring since 2005.

The second effect of increased CO2 in the atmosphere is the melting of ice caps and glaciers. The warming of the Earth's atmosphere has caused the polar ice caps to melt at an alarming rate. According to NASA, the Arctic sea ice extent has declined by about 13.4% per decade since 1979. The melting of ice caps and glaciers has contributed to the rising sea levels, which pose a significant threat to coastal communities and low-lying countries. It is estimated that global sea levels have risen by about 8 inches (21 cm) since 1880, and the rate of sea-level rise has accelerated in recent years.

The third effect of increased CO2 in the atmosphere is extreme weather events. Climate change has caused more frequent and severe weather events such as heatwaves, droughts, and storms. For example, the United States has experienced an increase in the frequency and severity of heatwaves, which can lead to heatstroke, dehydration, and other health problems. In addition, the frequency of extreme rainfall events has increased in many parts of the world, leading to flooding, landslides, and other natural disasters.

The fourth effect of increased CO2 in the atmosphere is ocean acidification. When CO2 is absorbed by seawater, it forms carbonic acid, which makes the water more acidic. This process is known as ocean acidification, and it has significant implications for marine life. Acidic water makes it difficult for marine organisms such as corals and shellfish to form their shells and skeletons. This can lead to a decline in the population of these organisms, which can have a ripple effect on the entire marine ecosystem.

The fifth effect of increased CO2 in the atmosphere is the loss of biodiversity. Climate change has led to changes in temperature and rainfall patterns, which have affected ecosystems and biodiversity. Many plant and animal species are struggling to adapt to the rapidly changing climate, and some are facing extinction. For example, the polar bear population is declining due to the loss of sea ice, which is their primary hunting ground. The loss of biodiversity can have significant ecological and economic impacts, as many species play important roles in maintaining the health of ecosystems and supporting human livelihoods.

In conclusion, increased CO2 in the Earth's atmosphere over the past 100 years has had significant and far-reaching effects on the planet. The effects of global warming, such as rising temperatures, melting ice caps, extreme weather events, ocean acidification, and the loss of biodiversity, are threatening the health and wellbeing of people and the environment. Urgent action is needed to reduce greenhouse gas emissions, mitigate the impacts of climate change, and protect the planet
