Paper For Above instruction

The urgency of understanding global climate change has never been more critical, given its profound implications for the environment, society, and the economy. This paper provides a comprehensive overview of the scientific principles behind the greenhouse effect, evidence of global warming over the past century, and the technological advancements in satellite monitoring. It also explores the major contributors to greenhouse gases globally and assesses the multifaceted impacts of climate change on both the environment and societies worldwide.

Greenhouse Gases and Their Role in Climate Change

Major greenhouse gases include carbon dioxide (CO₂), methane (CH₄), nitrous oxide (N₂O), and fluorinated gases. According to the Global Carbon Project (2022), CO₂ constitutes approximately 76% of human-caused greenhouse gases, primarily emitted from fossil fuel combustion and deforestation. Methane accounts for about 16%, mainly from agriculture, livestock, and landfills, while nitrous oxide makes up around 6%, largely from agricultural activities and industrial processes. Fluorinated gases, although present in smaller quantities, possess high global warming potentials (GWP).

The greenhouse effect operates on the physical principle that certain gases trap infrared radiation emitted from Earth’s surface, preventing it from escaping into space. This trapped heat maintains the planet’s temperature within a range capable of sustaining life. However, excess greenhouse gases intensify this natural process, leading to global warming. The benefits of this effect include maintaining habitable temperatures; however, the drawbacks are evident in climate destabilization, melting ice caps, and extreme weather events (Kump et al., 2017).

Historical Data of Global Temperature and Greenhouse Gases

Data collected over the last century reveal a significant rise in global temperatures. According to NASA's Goddard Institute for Space Studies (GISTEMP), the global land and ocean surface temperature has increased by about 1.2°C since 1900. This rise correlates strongly with increased greenhouse gas concentrations, which have nearly doubled since pre-industrial times (Jones et al., 2019). The acceleration in temperature rise corresponds with industrialization, fossil fuel consumption, and deforestation.

Satellite Monitoring of Greenhouse Gases

Several satellites actively monitor atmospheric greenhouse gases. Examples include the Orbiting Carbon Observatory-2 (OCO-2), launched by NASA in 2014, which has a weight of approximately 660 kg, with an orbit at 705 km altitude following a sun-synchronous path with a revisit period of about 16 days. It detects CO₂ concentrations using spectrometers capable of analyzing sunlight reflected off Earth’s surface. The European Space Agency’s Sentinel-5P, launched in 2017, uses the TROPOspheric Monitoring Instrument (TROPOMI) to identify multiple gases, including NO₂, CO, and CH₄, providing high-resolution data essential for tracking emission sources (VeefKind et al., 2018).

Data collected from these satellites have revealed spatial and temporal patterns of greenhouse gas concentrations, identifying emission hotspots worldwide and informing policy measures.

Major Greenhouse Gas Contributors and Their Impacts

The top ten countries contributing to global greenhouse gas emissions include China, the United States, India, Russia, Japan, Iran, Germany, Indonesia, Saudi Arabia, and South Korea. Each country’s emission profile is shaped by its economic activities, energy policies, and industrial sectors. For example, China’s emissions predominantly originate from coal-based power generation, manufacturing, and construction (Rahman et al., 2020). In contrast, the United States’ emissions are driven by transportation, industry, and energy production.

Focusing on China and India, two leading emitters, illustrates the environmental impacts of increased greenhouse gases. In China, high emissions have contributed to deteriorating air quality, affecting freshwater supplies through pollution runoff, reducing fish stocks, and harm to biodiversity (Li et al., 2020). Similarly, India’s increased emission levels threaten water security by contaminating groundwater and surface water, adversely affecting agriculture, fisheries, and wildlife.

Effects on Society and Economy

The social implications of rising greenhouse gases include heightened health risks, such as respiratory and vector-borne diseases, especially in densely populated areas like India. Additionally, economic impacts are evident in increased costs related to climate-induced disasters, healthcare, and loss of productivity (Satesh et al., 2020). For example, Bangladesh anticipates severe flooding due to sea-level rise, which jeopardizes its economy and displaces millions of people.

Evidence of Climate Change and Its Impact

Evidence of climate change is manifold. Ocean temperature measurements indicate rising sea surface temperatures, which disrupt marine ecosystems and increase the frequency of hurricanes. The Arctic ice sheet has been shrinking at an alarming rate, contributing to sea-level rise, which threatens coastal cities globally (Meyer et al., 2019). Additionally, climate change correlates with an increase in extreme weather events such as droughts, floods, and heatwaves, destabilizing food and water security worldwide.

International Efforts and Policies to Mitigate Climate Change

The Paris Agreement, adopted in 2015, is a landmark international treaty aiming to limit global temperature rise below 2°C. Its core principles include nationally determined contributions (NDCs), transparency, and financial support to developing nations. Countries are encouraged to set emission reduction targets aligned with their capacities (UNFCCC, 2015). Policies to mitigate emissions involve transitioning to renewable energy sources, enhancing energy efficiency, afforestation, and implementing carbon pricing mechanisms. Individuals can contribute by reducing energy consumption, adopting sustainable practices, and supporting policies that promote environmental conservation (Stern, 2021).

Conclusion

Addressing global climate change requires a multifaceted approach that combines technological, policy, and behavioral changes. Satellite data plays an indispensable role in monitoring emissions and informing decision-making. Equally important are international agreements like the Paris Accord and collective efforts at the national and individual levels. As climate impacts become increasingly severe, proactive measures are essential to safeguarding the planet’s future for generations to come.
