Essay on Global Warming

Summary:

Global warming is causing Earth’s temperatures to rise faster than past climate changes due to human activities. The main causes include burning fossil fuels, deforestation, and certain agricultural and industrial practices, leading to increased levels of greenhouse gases like carbon dioxide and methane.

From 2013 to 2022, the average global temperature increased by 1.14°C above the pre-industrial baseline, showing that long-term warming continues. This period witnessed severe weather events, including large-scale floods in Pakistan in 2022 and devastating landslides in North India in 2013, indicating the tangible impacts of climate change.

Major contributors to global emissions include the transportation sector, with cars contributing 82%, followed closely by electricity production. The lockdowns during the COVID-19 pandemic revealed a noticeable decrease in pollution and an increase in oxygen levels due to reduced transportation usage. The US has the highest per capita carbon emissions, and 100 major companies, primarily in oil and coal, account for 71% of global greenhouse gas emissions.

To mitigate global warming, the top three areas that need immediate attention are:

Transportation, especially reducing the use of cars.
Electricity production, focusing on renewable sources.
Regulation of major companies responsible for a significant portion of greenhouse emissions.

Essay on Global Warming

Examine the effects of global warming in the past 10 years and the science behind this. Choose three areas that need targeting immediately to slow down global warming.

Global warming, the global average temperature, is increasing, affecting Earth’s climate system. Climate change also includes past long-term changes to Earth’s climate. The current rise in temperature is faster than previous changes. The uses of fossil fuels, deforestation, and certain agricultural and industrial practices release greenhouse gases, such as Carbon dioxide and Methane. These gases trap heat in Earth’s lower atmosphere, leading to Global warming.

The 10-year average temperature for 2013-2022 is 1.14 (1.02 to 1.27) oC above the 1850-1900 pre-industrial baseline. This compares with 1.09 C from 2011 to 2020, as the Intergovernmental Panel on Climate Change (IPCC) Sixth Assessment report estimates, and indicates that long-term warming continues.
