The Mesmerizing Effects of Carbon Dioxide Emissions

Our CO2 emissions are warming the planet and making life uncomfortable and even unbearable in some regions. In July, the planet set consecutive records for the hottest day. NASA is mapping our emissions, and while what they show us isn’t uplifting, it is visually appealing in a ghoulish way. Maybe the combination of visual appeal and ghoulishness will build momentum in the fight against climate change.

NASA’s Scientific Visualization Studio has released a video showing how wind and air currents pushed CO2 emissions around Earth’s atmosphere from January to March 2020. The video’s high resolution zooms in and sees individual sources of CO2, including power plants and forest fires.

Global CO2 Emission Sources

The video starkly shows that it doesn’t matter where CO2 emissions come from; we all deal with the outcomes. Yet there are some interesting global differences. Above the USA, South Asia, and China, most of the carbon comes from industry, power plants, and transportation. But over Africa and South America, most of the emissions come from burning, including forest fires, agricultural burning, and land clearing. Emissions also come from fossil fuels like oil and coal.

Key Sources of CO2 Emissions:

Industry: Factories and industrial processes release large amounts of CO2.
Power Plants: Burning fossil fuels for electricity is a major source of emissions.
Transportation: Cars, trucks, ships, and airplanes contribute significantly to CO2 levels.
Burning: Forest fires, agricultural burning, and land clearing are prominent in Africa and South America.

The Pulsing Effect

The image pulses for a couple of reasons. Forest fires tend to flare during the day and then slow down at night. Also, trees and plants photosynthesize during the day, releasing oxygen and absorbing CO2. The land masses and the oceans act as carbon sinks. There’s more pulsing in South America and the tropics because the data was collected during their growing season.

This article delves into the UN’s role in addressing climate change, examining key agreements, scientific contributions, financial mechanisms, and the challenges faced in this global quest.

History of UN Climate Change Initiatives

The Birth of the UNFCCC

The United Nations Framework Convention on Climate Change (UNFCCC), adopted at the Earth Summit in Rio de Janeiro in 1992, is a landmark treaty that established a global framework for addressing climate change. The UNFCCC’s primary objective is to stabilize greenhouse gas concentrations in the atmosphere at a level that would prevent dangerous anthropogenic interference with the climate system.

The Kyoto Protocol

The Kyoto Protocol was adopted in 1997 and came into force in 2005. It was the first agreement under the UNFCCC to set legally binding emission reduction targets for developed countries. The protocol established a system of emissions trading, clean development mechanisms, and joint implementation to help countries meet their targets cost-effectively.

The Paris Agreement

The Paris Agreement, adopted in 2015 and coming into force in 2016, represents a significant milestone in global climate policy. The agreement’s central aim is to limit global warming to well below 2°C above pre-industrial levels, with efforts to keep the increase to 1.5°C. This ambitious target requires substantial reductions in greenhouse gas emissions worldwide.

Key components of the Paris Agreement include:

Nationally Determined Contributions (NDCs): Each country submits their own targets and plans to reduce emissions.
Global stocktake: Every five years, countries review progress and enhance their NDCs.
Climate finance: Developed countries commit to providing financial support to developing countries.

UN Bodies and Programs Supporting Climate Action

The Intergovernmental Panel on Climate Change (IPCC)

The Intergovernmental Panel on Climate Change (IPCC), established in 1988, is a UN body responsible for assessing the science related to climate change. The IPCC provides comprehensive reports that synthesize the latest scientific findings, helping policymakers make informed decisions. Its assessments have been crucial in highlighting the urgency of climate action.

The UN Environment Programme (UNEP)

The United Nations Environment Programme coordinates responses to environmental issues within the United Nations system. Maurice Strong, its first director, established it. This followed the United Nations Conference on the Human Environment in Stockholm in June 1972.

The Green Climate Fund

The Green Climate Fund was established to support developing countries in reducing and adapting to climate change. It provides financial assistance to projects that promote sustainable development and reduce greenhouse gas emissions.

Major UN Climate Agreements and Frameworks

The Kyoto Protocol

The Paris Agreement

The Paris Agreement is a landmark accord that brings together nations to combat climate change. It requires countries to submit nationally determined contributions (NDCs) outlining their climate actions. The agreement also emphasizes transparency and regular reporting to track progress.

Key Elements of the Paris Agreement

Nationally Determined Contributions (NDCs): Each country sets its own targets for reducing emissions.
Global Stocktake: Every five years, a global assessment is conducted to evaluate progress and inform future actions.
Climate Finance: Developed countries are expected to provide financial support to developing countries for climate action.

Challenges in UN Climate Action

Political Resistance

One of the significant challenges is political resistance from certain countries and leaders who may prioritize short-term economic gains over long-term environmental sustainability. This resistance can hinder the implementation of global climate agreements.

Inadequate Funding

Despite efforts to mobilize financial resources, funding for climate action remains insufficient. Many developing countries struggle to access the necessary funds to implement effective climate mitigation and adaptation strategies.

Varying Commitments

The level of commitment to climate action varies among UN member states. While some countries are leading in climate initiatives, others lag due to economic, political, or social reasons. This disparity creates challenges in achieving global climate goals.

Successes and Progress

Enhanced Global Cooperation

The UN has successfully fostered international cooperation on climate change. The Paris Agreement, with its widespread adoption, exemplifies the collective effort of countries to address this global issue.

Scientific Advancements

The work of the IPCC has significantly advanced our understanding of climate change. Its reports provide critical scientific evidence that shapes policy decisions and public awareness.

Increased Climate Financing

Efforts to increase climate financing have shown progress. Initiatives like the Green Climate Fund have mobilized resources to support climate action in developing countries.

Future Directions

Strengthening Global Cooperation

Enhancing international cooperation is crucial for future climate action. The UN aims to foster more robust partnerships and collaborations among countries, businesses, and civil society.

Increasing Financial Support

Scaling up financial support for climate action is essential. This includes not only increasing funding but also ensuring that resources are effectively utilized to achieve maximum impact.

Building Climate Resilience

Future efforts will focus on building resilience to climate impacts, especially for vulnerable communities. This involves investing in sustainable infrastructure, early warning systems, and disaster risk reduction strategies.

Promoting Sustainable Development

The UN’s Sustainable Development Goals (SDGs) highlight the importance of integrating climate action with broader development objectives. Achieving these goals requires a holistic approach that addresses social, economic, and environmental dimensions.

Conclusion

The United Nations has been instrumental in the global fight against climate change. Through frameworks like the UNFCCC, agreements such as the Kyoto Protocol and the Paris Agreement, and the efforts of various UN bodies, significant progress has been made. However, challenges remain, and continued efforts are needed to ensure a sustainable and resilient future.

Sea Level Rise: The Looming Crisis

By Jonathan Bala May 24, 2024

Sea Level Rise: The Looming Crisis

Key Takeaways

Sea level rise is a consequence of climate change, driven by the melting of glaciers and polar ice sheets, and the thermal expansion of seawater. The global average sea level is projected to rise by nearly 1 foot by 2050 and potentially more than 3 feet by 2100. Coastal areas, particularly those in the United States, are already experiencing increased flooding, saltwater intrusion, and economic impacts due to rising seas. Strategies to adapt to sea level rise include building sea walls, elevating infrastructure, and implementing nature-based solutions. Policy solutions such as managed retreat, climate adaptation funding, and international cooperation are essential to mitigate and adapt to rising sea levels.

Summary

Global causes: Melting ice sheets, thermal expansion of seawater.
Local causes: Groundwater pumping, tectonic shifts, local geology.
Effects: Extreme weather, tidal flooding, land loss, economic impacts, saltwater intrusion, climate migration.
Responses: Property protection, infrastructure adaptations, nature-based solutions, policy interventions.
Future projections: 1 foot rise by 2050, over 3 feet by 2100, with higher scenarios predicting up to 6.6 feet by the end of the century.
Challenges: Economic costs, displacement of communities, contamination of freshwater resources.

What is Sea Level Rise?

Sea level rise refers to the increase in the total volume of ocean water, resulting primarily from the melting of glaciers and polar ice sheets and the thermal expansion of seawater as it warms. These changes are driven by climate change, which is caused by the burning of fossil fuels.

Types of Sea Level Rise

Global Mean Sea Level Rise: This is the global average sea level change relative to a fixed point, such as the center of the Earth. It reflects the overall increase in the volume of the ocean and is most directly linked to climate change.
Relative Sea Level Change: This measures the height of the ocean’s surface relative to a specific piece of land. It can be influenced by both rising water levels and changes in land elevation.

In 2022, U.S. agencies like NOAA projected several scenarios for future sea level rise, depending on greenhouse gas emissions. These scenarios predict a global mean sea level rise of almost 1 foot by 2050 and more than 3 feet by 2100 under intermediate scenarios. In high-emission scenarios, sea levels could rise by up to 6.6 feet by the end of the century.

Table 1: Projected Global Sea Level Rise Scenarios

Scenario	2050 Projection (Feet)	2100 Projection (Feet)
Low	0.6 – 1.2	1.6 – 3.3
Intermediate	0.9 – 1.8	2.3 – 4.9
High	1.2 – 2.0	3.3 – 6.6

Global Causes of Sea Level Rise

Melting Ice

Melting ice from glaciers and polar ice sheets is a significant contributor to sea level rise. For instance, the Greenland ice sheet loses about 270 billion tons of ice each year.

Thermal Expansion

As the oceans absorb heat from greenhouse gases, the water expands. This process, known as thermal expansion, has contributed to one-third of the global sea level rise since 2004.

Local Causes of Sea Level Rise

Local Geology

In some areas, geological factors cause land to sink, making the sea appear to rise faster. Norfolk, Virginia, is one such example, built on a slowly sinking impact crater.

Tectonic Shifts

Tectonic movements can also affect local sea levels. For example, parts of California are being pushed upward, masking the effects of sea level rise.

Groundwater Pumping

Extracting groundwater can cause land to settle, leading to a relative rise in sea levels. Jakarta, Indonesia, is sinking rapidly due to excessive groundwater pumping.

Effects of Sea Level Rise

Rising sea levels amplify the effects of extreme weather events. Higher baseline water levels mean that storm surges and flooding will be more severe.

Tidal Flooding

Coastal areas are experiencing more frequent high tide floods, known as “nuisance” or “sunny day” floods. NOAA projects that by 2050, the U.S. will see an average of 45 to 85 high tide flooding days per year.

Land Loss and Coastal Erosion

Rising seas will permanently submerge some areas of land and accelerate coastal erosion. By 2050, 4.4 million acres of U.S. properties could be below tide lines.

Economic Impacts

Sea level rise threatens costly infrastructure like sewage plants and power stations. The economic losses could reach trillions of dollars by 2100, with annual costs of $14 trillion from adaptation efforts alone.

Table 2: Economic Impacts of Sea Level Rise

Impact	Annual Cost (By 2100)
Property Loss	$500 million
Infrastructure Damage	$14 trillion
Energy Facilities	Nearly 300 at risk
Transportation	2,400 miles of roadway

Saltwater Intrusion and Freshwater Contamination

Saltwater intrusion from rising seas threatens freshwater sources and agricultural lands, particularly in coastal areas like Miami and Bangladesh. This contamination can lead to water insecurity and displacement.

Climate Migration

Rising sea levels will force populations to relocate, creating potential refugee crises. Up to 13 million people in the U.S. and millions more globally could be displaced by permanent inundation.

Responses and Adaptations to Rising Sea Levels

Strategies for Property Owners

Flood Risk Assessment: Use flood maps to understand your risk.
Flood Insurance: Purchase insurance to protect against potential losses.
Home Elevation: Elevate homes and important possessions to avoid flood damage.
Relocation: Consider moving to safer, higher ground.

Strategies for Infrastructure

Sea Walls: Construct barriers to protect against flooding and storm surges.
Elevated Roads: Raise roads to prevent flooding.
Water Pumps: Install pumps to remove collected water.

Nature-Based Strategies

Preserving and restoring natural defenses like wetlands, dunes, and mangroves can reduce flood risks and provide additional benefits like recreation and food sources.

Policy Solutions

Engage at-risk communities in long-term planning to relocate infrastructure and homes to safer areas while bolstering resilience where necessary. Increase state and federal funding for climate adaptation projects, reform flood insurance programs, and protect critical infrastructure. International cooperation is essential. Major polluters must fulfill their commitments to reduce emissions, invest in clean energy, and support vulnerable nations through initiatives like the Green Climate Fund.

Conclusion

Sea level rise presents a significant challenge that requires immediate and sustained action. From understanding the science behind it to implementing practical and policy solutions, every effort counts. As the impacts of rising seas become more evident, it is crucial for governments, communities, and individuals to work together to mitigate risks and adapt to the changing climate.

How Small Aerosols Shape Cloud Formation

By Jonathan Bala May 5, 2024

How Small Aerosols Shape Cloud Formation

Key Takeaway

The study reveals that aerosols as small as 25-30 nanometers, much smaller than previously thought, can initiate cloud formation, which challenges current climate models and suggests the need for recalibration to account for the influence of these tiny aerosols on cloud formation and climate predictions.

Summary

A recent collaborative study utilizing global satellite data and direct observations off the California coast shows that aerosol particles as small as 25-30 nanometers are crucial for cloud development, contrary to the established norm of 60 nanometers.
Clouds are essential components of Earth’s climate system, but they also constitute one of the largest uncertainties in understanding climate change.
The study focused on the behavior of cloud condensation nuclei within marine stratus clouds and found that the size threshold required for these nuclei to trigger cloud formation is much smaller than previously believed.
Traditionally, it was thought that cloud condensation nuclei had to be relatively large, but the researchers discovered that even smaller proto-seeds can serve as effective nuclei.
The sensitivity of cloud formation to these smaller aerosols arises because they can be activated into cloud droplets in conditions where water is highly supersaturated.
The combined observations from marine stratus clouds and global data from the MODIS satellite instrument revealed a consistent pattern of higher-than-expected supersaturation across the globe, adjusting the scale of critical seed size downwards.
The discovery that smaller aerosols can effectively contribute to cloud formation suggests that climate models need to be recalibrated to account for these dynamics, potentially improving predictions of future climate scenarios.
The study not only challenges established paradigms in climatology but also opens the door for further investigations into the delicate interplays at the heart of our planet’s climate system.

Tiny Aerosols: The Unexpected Key Players in Cloud Formation

Cloud formation is a complicated process that has always interested scientists and climatologists. Clouds are crucial to our atmosphere. They help regulate Earth’s climate by reflecting sunlight and interacting with thermal radiation. A recent groundbreaking study has challenged our understanding of how clouds form.

Traditionally, it was believed that cloud condensation nuclei – the seed particles around which water condenses to form clouds – had to be relatively large, typically around 60 nanometers or larger. This belief was deeply ingrained in climate models and our understanding of atmospheric processes.

However, a collaborative research effort involving scientists from The Technical University of Denmark, the University of Copenhagen, and the Hebrew University of Jerusalem has uncovered a surprising truth that could redefine our approach to climate modeling.

Through a combination of global satellite data and direct observations off the California coast, the researchers made a remarkable discovery: aerosol particles as small as 25-30 nanometers can initiate cloud formation. This finding challenges the long-held assumption that larger particles are necessary for this process.

The study focused specifically on the behavior of cloud condensation nuclei within marine stratus clouds, which are prevalent over vast swaths of the Earth’s oceans. The researchers found that the size threshold required for these nuclei to trigger cloud formation is much smaller than previously believed.

The sensitivity of cloud formation to these smaller aerosols arises from a fundamental principle: the denser the water vapor, the smaller the necessary seed particle. In other words, in conditions where water is highly supersaturated, even minuscule aerosol particles can catalyze the formation of cloud droplets.

This revelation deeply affects our understanding of climate dynamics. It also impacts the accuracy of climate models.

The study’s findings suggest that current climate models may be underestimating the influence of smaller aerosols on cloud formation, particularly in pristine areas where marine stratus clouds dominate. As a result, these models may need to be recalibrated to account for the dynamics of these tiny particles.

Henrik Svensmark, the lead author of the study, emphasized the significance of this discovery:

“Current models show that due to the growth time, most of the small aerosols are lost before they grow to the critical size, and thus, cloud formation is rather insensitive to changes in the production of small aerosols. Our results change this understanding as aerosols must grow much less, which is important for modeling clouds and climate predictions.”

This study challenges existing ideas in climatology and encourages more research into our planet’s climate system. It focuses on the complex interactions involving aerosols, water vapor, and clouds. Exploring this balance is crucial because it deeply affects our understanding of climate change and its consequences.

Why Is the North Pole Warming Faster Than Any Other Region?

By Jonathan Bala May 5, 2024

Why Is the North Pole Warming Faster Than Any Other Region?

Key Takeaway

The North Pole is warming at an alarmingly rapid pace compared to the rest of the planet due to the combined effects of lingering ozone and the influx of warm air masses from lower latitudes.

Summary

The Arctic is experiencing intense warming several times faster than the global average, signaling major disruptions in both the Arctic and global climate systems.
Dr. Barten’s research at Wageningen University reveals two key factors driving the accelerated warming at the North Pole:
- Ozone, a potent greenhouse gas, is lingering longer in the Arctic atmosphere than previously assumed, amplifying its warming effect.
- Warm air masses from lower latitudes are increasingly intruding into the Arctic region, transporting additional ozone and directly contributing heat.
Soot particles from fossil fuel combustion, when deposited on Arctic snow and ice, absorb solar radiation and accelerate melting.
The melting of Arctic ice has falling effects beyond the polar regions, including rising sea levels, more intense storms, prolonged droughts, and heatwaves.
Transitioning away from fossil fuel dependence, prioritizing clean energy sources, and promoting sustainable practices are crucial steps to slow Arctic warming.
Raising awareness and demanding bolder climate action from leaders and businesses are essential to address the urgency of the situation.

Insights into a Warming World

The Arctic is facing a quiet crisis. It threatens our planet’s climate balance. The North Pole used to be covered in pure ice and snow. Now, it is the center of a worrying change. Temperatures are rising quickly, faster than ever before. Scientists are urgently trying to figure out what is causing this swift increase in warmth.

The Arctic’s warming is not just a local problem; it signals worldwide climate change. Studies show that the Arctic is warming much faster than the rest of the world. This rapid warming raises the alarm for significant disruptions in the Arctic and the global systems it affects.

Dr. Barten from Wageningen University has identified two main causes of the North Pole’s rapid warming: ozone and warm air intrusions.

Ozone is usually known for protecting us from the sun’s harmful rays high in the atmosphere. However, it also acts as a powerful greenhouse gas near the Earth’s surface. In the Arctic, certain atmospheric conditions cause ozone to stay longer, increasing its warming effect.

Dr. Barten notes, “In the Arctic, ozone is absorbed by seawater, snow, and ice, but this happens slower than we thought. This slow absorption keeps more ozone in the air, warming the region.”

Traditionally stable, cold Arctic air is now frequently disrupted by warmer air from the south. These warmer air spells, driven by broader climate change, are more common and severe. They not only bring more ozone to the Arctic but also melt ice faster, strengthening the warming cycle.

The idea of the Arctic as a remote, untouched wilderness is quickly disappearing. Industrial activities produce soot, a byproduct of burning fossil fuels, which travels long distances and settles on Arctic ice and snow.

Soot, unlike reflective white snow and ice, absorbs solar energy. This absorption speeds up the melting of the Arctic ice, leading to higher sea levels and disrupted ecosystems.

Ignoring the melting Arctic as a distant issue is misleading. The Arctic is vital to the Earth’s climate system, with its changes affecting the entire planet.

Melting Arctic ice directly raises ocean levels, threatening global coastal areas with more floods and displacing millions. The Arctic also shapes global weather patterns by influencing major air and water currents that distribute heat and moisture worldwide.

As the Arctic’s systems are thrown off, we experience effects like:

More intense storms in regions accustomed to mild climates
Prolonged droughts that decimate crops and threaten food supplies
Heatwaves and temperature swings that push infrastructure (and human bodies) to their limits

The situation is urgent but not hopeless. We have powerful tools to slow and potentially limit the Arctic’s transformation. Our choices and policy support can directly affect how quickly and extensively the area warms.

The main cause of global warming, including changes in the Arctic, is our reliance on fossil fuels. To combat this, we must prioritize clean, renewable energy, invest in energy efficiency, and quickly reduce our dependence on fossil fuels.

Even small actions can make a big difference when millions of people participate. Simple steps like conserving energy at home, using public transit or biking, and demanding environmentally responsible practices from businesses are important.

The trouble of the Arctic must be a key topic in climate discussions. We need to voice our concerns to leaders, representatives, and businesses, urging them to take bold climate action. Policies need to match the urgency of the situation.

The transformation of the Arctic is a clear indicator of how connected our planet’s systems are and the extensive impacts of our actions. By understanding what drives the rapid warming at the North Pole, we can aim for a sustainable future. This future would preserve the Arctic’s beauty and maintain the balance of our global climate.
