<h2>Section-1: Introduction</h2>
<p>Climate change is one of the most pressing issues facing our planet today. It is a complex issue with far-reaching consequences that affect all aspects of our lives.</p>
<p>Climate change refers to the long-term shifts in temperature and typical weather patterns, mainly caused by human activities, especially the burning of fossil fuels. These shifts have a variety of effects on humans and the planet.
Climate change is caused by the accumulation of greenhouse gases (GHGs) in the atmosphere. These gases trap heat from the sun, causing the planet to warm. The main GHGs are carbon dioxide, methane, nitrous oxide, and fluorinated gases.
Human activities, such as burning fossil fuels, deforestation, and agriculture, have increased the concentration of GHGs in the atmosphere. This has led to a rapid rise in global temperatures, which is causing a variety of changes in the climate system.</p>

<li><strong>Causes of Climate Change</strong></li>
The main cause of climate change is human activity, primarily the burning of fossil fuels such as coal, oil, and natural gas. These activities release
green house gases, such as carbon dioxide, into the atmosphere. These gases trap heat from the sun, causing the Earth’s temperature to rise.<p></p>
<div class="box" style="background-color: rgb(255, 243, 243); border: 2px solid black;">
<strong>Green house gases:</strong> Greenhouse gases are the gases in the atmosphere that raise the surface temperature of planets such as the Earth. What
distinguishes them from other gases is that they absorb the wavelengths of radiation that a planet emits, resulting in the greenhouse effect. The Earth is
warmed by sunlight, causing its surface to radiate heat, which is then mostly absorbed by water vapor (H<sub>2</sub>O), carbon dioxide (CO<sub>2</sub>),
methane (CH<sub>4</sub>), nitrous oxide (N<sub>2</sub>O), and ozone (O<sub>3</sub>). Without greenhouse gases, the average temperature of Earth's surface
would be about −18 °C (0 °F), rather than the present average of 15 °C (59 °F) [<a href="https://en.wikipedia.org/wiki/Greenhouse_gas" target="_blank">Reference</a>].
(for Celsius to Fahrenheit conversion see the [<a href="https://www.metric-conversions.org/temperature/celsius-to-fahrenheit.htm" target="_blank">link</a>])
<br>
<strong>Green house effect:</strong> The greenhouse effect occurs when greenhouse gases in a planet's atmosphere trap some of the heat radiated from the
planet's surface, raising its temperature. This process happens because stars emit shortwave radiation that passes through greenhouse gases, but planets
emit longwave radiation that is partly absorbed by greenhouse gases. That difference reduces the rate at which a planet can cool off in response to being
warmed by its host star. Adding to greenhouse gases further reduces the rate a planet emits radiation to space, raising its average surface temperature

<li><strong>Impacts of Climate Change</strong></li>
Climate change is already having a significant impact on our planet. The Earth’s average temperature has risen by about 1 degree Celsius since the
pre-industrial period. This may not seem like much, but it is enough to cause a range of changes, including:
<ul>
<li><strong>Rising sea levels: </strong>As the Earth’s temperature rises, more water evaporates from the oceans. This water then returns to the
Earth in the form of rain or snow, but some of it remains in the atmosphere as vapor. This causes the oceans to expand, and sea levels to rise.</li>
<li><strong>Extreme weather events: </strong>Climate change is causing more extreme weather events, such as heat waves, droughts, floods, and wildfires.
These events are having a devastating impact on communities around the world.</li>
<li><strong>Loss of biodiversity: </strong>Climate change is also hurting biodiversity. The Earth’s ecosystems are being disrupted, and many species are being lost.</li>
</ul>
<li><strong>Mitigation and Adaptation</strong></li>
There are two main approaches to addressing climate change:
<ul>
<li><strong>Mitigation: </strong>Mitigation involves reducing greenhouse gas emissions and preventing further warming. This can be done by switching to
renewable energy sources, improving energy efficiency, and planting trees.</li>
<li><strong>Adaptation: </strong>Adaptation involves preparing for the impacts of climate change that are already happening. This can include building
seawalls to protect coastal communities from rising sea levels and developing drought-resistant crops.</li>
</ul>
<li><strong>International Cooperation</strong></li>
Addressing climate change requires international cooperation. The <a href="https://unfccc.int/process-and-meetings/the-paris-agreement#:~:text=The%20Paris%20Agreement%20is%20a,force%20on%204%20November%202016." target="_blank">Paris Agreement</a>, adopted in 2015, is an international treaty that aims to limit global
warming to well below 2 degrees Celsius, preferably to 1.5 degrees Celsius, compared to pre-industrial levels. The agreement also aims to strengthen the
ability of countries to deal with the impacts of climate change.
<li><strong>Individual Actions</strong></li>
While international cooperation is essential, individual actions can also make a difference. There are many things that we can do as individuals to reduce
our carbon footprint and help to address climate change. These include:
<ul>
<li>Driving less and walking, biking, or taking public transportation more often.</li>
<li>Using less energy at home by using energy-efficient appliances, turning off lights when not in use, and taking shorter showers.</li>
<li>Eating less meat and more plant-based foods.</li>
<li>Reducing, reusing, and recycling.</li>
</ul>
</ol>
Climate change is a complex and challenging issue, but it is not insurmountable. With international cooperation, individual action, and technological innovation,
we can address climate change and build a more sustainable future.

<h2>How to address the climate change</h2>
Addressing climate change requires a multifaceted approach that encompasses mitigation, adaptation, and international cooperation. Here are some of the key strategies
currently being considered and implemented to curb the effects of climate change:
<ol>
<li><strong>Renewable Energy Transition: </strong>
Transitioning to renewable energy sources, such as solar, wind, and geothermal power, is crucial to reduce our reliance on fossil fuels, the primary contributors
to greenhouse gas emissions. Governments and industries are investing heavily in renewable energy technologies to increase their share in the global energy mix.
<figure>
<img src="assets/img/remote-sensing/climate-2.png" alt="" style="max-width: 80%; max-height: 80%;">
<figcaption style="text-align: center;"></figcaption>
</figure>
</li>
<li><strong>Energy Efficiency and Conservation: </strong>Improving energy efficiency in buildings, transportation, and industrial processes can significantly reduce
energy consumption and associated emissions. This involves adopting energy-efficient appliances, optimizing building designs, and promoting sustainable transportation options.
<figure>
<img src="assets/img/remote-sensing/climate-3.png" alt="" style="max-width: 50%; max-height: 50%;">
<figcaption style="text-align: center;">Image created by AI technologies.</figcaption>
</figure>
</li>
<li><strong>Carbon Capture and Storage (CCS): </strong>CCS technology captures carbon dioxide (CO<sub>2</sub>) emissions from industrial processes and stores them underground,
preventing them from entering the atmosphere. While CCS is not a standalone solution, it can complement other mitigation strategies to further reduce emissions.
<p></p>
<div class="box" style="background-color: rgb(255, 243, 243); border: 2px solid black;">
The key components of CCS technology include:
<ol>
<li><strong>Capture: </strong>
<ul>
<li><strong>Post-Combustion Capture: </strong>Involves removing CO<sub>2</sub> from the flue gas after the fossil fuel has been burned. This is often done using solvents or other chemical processes.</li>
<li><strong>Pre-COmbustion Capture: </strong>Occurs before the fossil fuel is burned, and it involves converting the fuel into a gas that allows for easier separation of CO<sub>2</sub>.</li>
</ul>
</li>
<li><strong>Transport: </strong>Once captured, the CO<sub>2</sub> is compressed into a dense form for efficient transportation. Pipelines are commonly used to transport CO<sub>2</sub> from capture facilities to storage sites.</li>
<li><strong>Storage: </strong>
<ul>
<li><strong>Geological Storage: </strong>The most common method involves injecting the captured CO<sub>2</sub> into deep geological formations, such as depleted oil and gas fields or deep saline aquifers.
The CO<sub>2</sub> is stored securely underground, reducing the risk of leakage.</li>
<li><strong>Ocean Storage:</strong> Involves injecting CO<sub>2</sub> into deep ocean waters, but this method raises environmental concerns and is not widely implemented due to potential ecological impacts.</li>
</ul>
</li>
</ol>
<p>The goal of CCS is to significantly reduce CO<sub>2</sub> emissions from large-scale point sources, such as power plants and industrial facilities, which are challenging to address through other means like renewable energy adoption
or energy efficiency improvements. CCS is often seen as a transitional technology to help achieve climate goals while continuing to use fossil fuels during the transition to a more sustainable energy mix.</p>
<p>It's important to note that while CCS has the potential to play a role in reducing emissions, it is not a standalone solution. It should be complemented by efforts to increase energy efficiency, transition
to renewable energy sources, and implement other sustainable practices to achieve comprehensive climate goals.</p>
</div><br>
</li>
<li><strong>Forest Conservation and Enhancement: </strong>Forests play a vital role in absorbing CO<sub>2</sub> from the atmosphere and storing it in their biomass. Protecting existing
forests and promoting reforestation efforts can significantly enhance the natural carbon sink and contribute to mitigating climate change.
<br><br>
<div class="box" style="background-color: rgb(255, 243, 243); border: 2px solid black;">
<p>Forests play a crucial role in absorbing carbon dioxide (CO<sub>2</sub>) through a process known as <a href="https://www.khanacademy.org/science/ap-biology/cellular-energetics/photosynthesis/a/intro-to-photosynthesis#:~:text=Photosynthesis%20is%20the%20process%20in,is%20released%20as%20a%20byproduct." target="_blank">photosynthesis</a>.
This natural mechanism is vital for mitigating climate change, as it helps remove CO<sub>2</sub> from the atmosphere and store
it in the form of carbon in trees and soil. Here's how forests contribute to absorbing CO<sub>2</sub> and reducing the impact of climate change:</p>
<ol>
<li><strong>Photosynthesis:</strong>
<ul>
<li><strong>Carbon Uptake:</strong> Trees, along with other plants, absorb CO<sub>2</sub> from the atmosphere during photosynthesis. In this process, they use sunlight, water, and carbon dioxide to produce oxygen and glucose (a form of sugar).</li>
<li><strong>Carbon Storage:</strong> The carbon from CO<sub>2</sub> is stored in the form of biomass, including leaves, stems, branches, and roots. As trees grow, they continue to accumulate carbon in their structures.</li>
</ul>
</li>
<li><strong>Carbon Sequestration:</strong>
<ul>
<li><strong>Above-Ground Biomass:</strong> The carbon stored in the above-ground parts of trees helps sequester carbon, preventing it from being released back into the atmosphere.</li>
<li><strong>Below-Ground Biomass:</strong> Tree roots and soil also store significant amounts of carbon, contributing to carbon sequestration. This carbon remains stored for years or even centuries.</li>
</ul>
</li>
<li><strong>Forest Ecosystems:</strong>
<ul>
<li><strong>Biodiversity:</strong> Forests support diverse ecosystems with a variety of plant and animal species. This biodiversity enhances the overall health and resilience of the ecosystem.</li>
<li><strong>Symbiotic Relationships:</strong> Some tree species form symbiotic relationships with fungi (mycorrhizal associations), which can increase nutrient uptake and carbon storage in soils.</li>
</ul>
</li>
<li><strong>Carbon Sink:</strong>
<ul>
<li><strong>Net Carbon Sink:</strong> A healthy, growing forest acts as a net carbon sink, meaning it absorbs more carbon through photosynthesis than it releases through processes like respiration and decay.</li>
</ul>
</li>
<li><strong>Climate Regulation:</strong>
<ul>
<li><strong>Local Climate:</strong> Forests influence local climates by providing shade, releasing water vapor through transpiration, and affecting wind patterns. These factors contribute to a more stable and favorable climate.</li>
</ul>
</li>
</ol>
The conservation and sustainable management of forests are essential for maximizing their carbon sequestration potential. Deforestation and forest degradation release stored carbon back into the atmosphere, contributing to increased CO2 levels and climate change. Therefore, efforts to prevent deforestation, promote afforestation (planting trees in areas that were not previously forested), and implement sustainable forestry practices are critical components of global climate change mitigation strategies.
</div>
</li>
<br><br>
<li><strong>Sustainable Land Use Practices: </strong>Sustainable land use practices, such as minimizing deforestation, adopting regenerative agriculture, and conserving
natural habitats, can help conserve carbon and promote biodiversity, further enhancing climate resilience.</li>
<li><strong>International Cooperation and Agreements: </strong>International cooperation is essential to address climate change on a global scale. The Paris Agreement, a
landmark international pact, outlines a global framework for reducing greenhouse gas emissions and adapting to climate change (for more details on the international cooperation, see the sectio below <a href="#sec-6">sec-6</a> ).</li>
<li><strong>Public Awareness and Behavioral Change: </strong>In addition to policy and technological interventions, fostering public awareness and encouraging behavioral
changes are crucial to mitigating climate change. This includes promoting sustainable lifestyles, reducing consumption, and supporting climate-friendly policies. </li>
</ol>

<h5>How Satellites Inform Climate Models:</h5>
Satellite data provides a wealth of information that is essential for refining and improving climate models. These models are complex computer programs that simulate the Earth's climate system and predict future climate changes
<ul>
<li><strong>Satellite data serves as "reality checks" for climate models: </strong>By comparing model simulations to satellite observations, scientists can identify and correct biases in the models.</li>
<li><strong>Satellite data provides key inputs for climate models: </strong>Satellite measurements of temperature, precipitation, and other climate variables are used to initialize and update climate models.</li>

<h2>International Cooperation and Agreements</h2>
Addressing climate change requires concerted global action and international cooperation. Several important agreements have been established to guide and support international efforts to
mitigate and adapt to climate change. Here are some of the key international agreements:
<ol>
<li><strong><a href="https://unfccc.int/" target="_blank">United Nations Framework Convention on Climate Change (UNFCCC)</a></strong>
<p>Adopted in 1992, the UNFCCC is the primary international treaty addressing climate change. It establishes a framework for countries to cooperate in the reduction of
<a href="https://en.wikipedia.org/wiki/Greenhouse_gas_emissions" target="_blank">greenhouse gas emissions</a> and the adaptation to the effects of climate change. The UNFCCC has been ratified by 197 parties, representing virtually every country in the world.</p>
</li>
<li><strong><a href="https://en.wikipedia.org/wiki/Kyoto_Protocol" target="_blank">Kyoto Protocol</a></strong>
<p>The Kyoto Protocol, adopted in 1997 and entered into force in 2005, is an international agreement that set legally binding emission reduction targets for industrialized
countries. The protocol aimed to reduce greenhouse gas emissions by an average of 5% below 1990 levels over the period 2008-2012. However, the United States, the world's
largest emitter at the time, never ratified the Kyoto Protocol, and some other major emitters also did not meet their targets.</p>

<li><strong><a href="https://en.wikipedia.org/wiki/Paris_Agreement" target="_blank">Paris Agreement</a></strong>
<p>The Paris Agreement, adopted in 2015, is a landmark international agreement that aims to strengthen the global response to the threat of climate change. It establishes a framework
for countries to voluntarily set ambitious national targets for reducing greenhouse gas emissions and to accelerate their efforts to adapt to the effects of climate change. The Paris
Agreement has been ratified by 196 parties, representing over 195 countries.</p>
</li>
<li><strong><a href="https://en.wikipedia.org/wiki/Intergovernmental_Panel_on_Climate_Change" target="_blank">Intergovernmental Panel on Climate Change (IPCC)</a></strong>
<p>The IPCC is an intergovernmental body established by the <a href="https://en.wikipedia.org/wiki/World_Meteorological_Organization" target="_blank">World Meteorological Organization (WMO)</a>
and the <a href="https://en.wikipedia.org/wiki/United_Nations_Environment_Programme" target="_blank">United Nations Environment Programme (UNEP)</a>
to provide the world with the most up-to-date scientific assessment of climate change. The IPCC assesses the physical science basis of climate change, its impacts, and the options for
mitigation and adaptation. The IPCC's reports are considered authoritative sources of information on climate change and have informed many international agreements and policies.</p>
</li>
<li><strong><a href="https://www.greenclimate.fund/" target="_blank">Green Climate Fund</a></strong>
<p>The Green Climate Fund (GCF) is a financial mechanism established to support developing countries in their efforts to mitigate and adapt to climate change. The GCF provides grants
and concessional financing to developing countries to invest in clean energy, protect forests, and build resilience to climate change impacts. The GCF has received pledges of over
$100 billion from developed countries, and it is expected to play a crucial role in supporting the implementation of the Paris Agreement.</p>
</li>
</ol>
These international agreements and initiatives provide a framework for international cooperation and action on climate change. As the world continues to grapple with the challenges of climate
change, these agreements and institutions will play an increasingly important role in supporting global efforts to mitigate and adapt to the impacts of a changing climate

<h2>Working Group on Climate</h2>
Working Group on Climate" can refer to two different organizations:
<ul>
<li><strong>Working Group I of the Intergovernmental Panel on Climate Change (IPCC): </strong>
The Intergovernmental Panel on Climate Change (IPCC) is the leading international body for the assessment of climate change. It is a scientific body composed of hundreds of
experts from all over the world. The IPCC Working Group I (WGI) assesses the physical science basis of climate change. This includes understanding the Earth's climate system,
how it is changing, and the potential impacts of climate change.
</li>
<li><strong>Working Group on Energy and Climate Change of the Economic Policy Committee (EPC): </strong>
The Economic Policy Committee (EPC) is an independent advisory body to the European Commission. The Working Group on Energy and Climate Change (WGEEC) of the EPC is responsible
for assisting and preparing the EPC's work on the economic and financial aspects of climate and energy policy, international climate policy, and the EU Energy Union.
</li>
</ul>
Here is a table summarizing the key differences between the two working groups:
