🌍 What is Global Warming? — A Comprehensive Explanation
✅ 1. Definition
Global warming is the long-term rise in Earth’s average temperature,
primarily due to the increased concentration of greenhouse gases in
the atmosphere. It is a central aspect of climate change, but not the
only one.
🌡️ In simple words: Global warming means the Earth is heating up over
time, mostly because of human activities that release gases which trap
heat.
🔬 2. Scientific Basis: The Greenhouse Effect
🌞 Natural Greenhouse Effect (Beneficial)
The Earth naturally traps some heat from the sun to stay warm. This
process is essential for life.
Sunlight enters Earth’s atmosphere.
The Earth’s surface absorbs it and radiates it back as infrared
heat.
Greenhouse gases (GHGs) like CO₂ and CH₄ trap some of this heat,
keeping Earth at a livable temperature.
🔥 Enhanced Greenhouse Effect (Harmful)
Due to human activities, more GHGs are being added to the
atmosphere, trapping too much heat—this causes global warming.
🧪 3. Main Greenhouse Gases & Their Sources
Gas Source Effect
Carbon dioxide Burning fossil fuels, Long-lasting, major
(CO₂) deforestation contributor
Livestock (cows), landfills, 25x more potent than
Methane (CH₄)
oil & gas CO₂
Nitrous oxide Fertilizers, industrial
300x stronger than CO₂
(N₂O) processes
Refrigerators, air Very potent but less
Fluorinated gases
conditioners common
🕰️ 4. Historical Context
Before the Industrial Revolution (1750s–1800s), CO₂ levels were
about 280 ppm (parts per million).
In 2024, CO₂ levels reached over 420 ppm, the highest in 800,000
years.
Most of this increase happened in the last 150 years, mainly due
to:
o Coal power plants
o Gasoline vehicles
o Deforestation
o Industrial expansion
📈 5. Current Global Trends (2020s–2025)
🌡️ Earth’s surface has warmed by 1.1°C since the 1880s.
📅 The last 9 years have been the warmest ever recorded.
🌊 Sea levels are rising by 3.3 mm/year.
❄️ Arctic sea ice is shrinking by 13% per decade.
🌪️ 6. Consequences of Global Warming
🔥 a. Extreme Weather
More heatwaves, wildfires, storms, floods.
Example: Australia’s 2020 wildfires burned 18 million hectares.
🌊 b. Rising Sea Levels
Melting glaciers and thermal expansion of oceans.
Example: Small island nations like Maldives are at risk of
submersion.
💧 c. Water Stress
Changing rainfall patterns lead to droughts or floods.
Example: Cape Town’s 2018 water crisis—almost ran out of
drinking water.
🌾 d. Threat to Agriculture
Heat reduces crop yields, threatens food security.
Example: In South Asia, rice and wheat production is already
declining due to changing monsoon patterns.
🐾 e. Biodiversity Loss
Habitats are shifting, many species can’t adapt fast enough.
Example: Coral bleaching in the Great Barrier Reef due to ocean
warming.
🏥 f. Public Health Issues
Increased spread of diseases like malaria, dengue, and
heatstroke.
Air pollution worsens respiratory conditions.
🌐 7. Human Role in Global Warming
Human activities are the main cause of global warming.
Major contributors:
Burning coal, oil, and gas for electricity and transport
Deforestation (less CO₂ absorption)
Industrial farming (methane from livestock)
Waste and overconsumption
📚 8. Real-World Case Studies
🇵🇰 Pakistan – 2022 Floods
Worst floods in a century
33 million affected, 1/3rd of the country submerged
Caused by melting glaciers + erratic monsoons (linked to global
warming)
🇧🇩 Bangladesh – Sea-Level Rise

🌍 Global Warming: Facts and Fiction – A Critical Analysis
Introduction
Global warming has emerged as one of the most urgent issues facing
humanity. While scientific consensus affirms its reality, a parallel
narrative of denial and misinformation persists. This essay aims to
distinguish the scientific facts of global warming from the fictional
beliefs, drawing on data, case studies, and expert opinions to critically
analyze the climate crisis.
🔹 FACTS: The Scientific Reality of Global Warming
1. Global Temperatures Are Rising
Fact: The Earth’s average surface temperature has increased by
approximately 1.1°C since the late 19th century.
Evidence: According to NASA and NOAA, the last decade (2011–
2020) was the hottest on record.
Case Study: The 2023 European heatwave broke records across
France, Spain, and Italy, with temperatures reaching above 45°C,
resulting in over 61,000 heat-related deaths (Lancet Report,
2023).
2. Human Activities Are the Main Cause
Fact: The Intergovernmental Panel on Climate Change (IPCC) has
stated with over 95% certainty that human activities, especially
the burning of fossil fuels, are the dominant cause of global
warming.
Mechanism: Burning coal, oil, and gas releases greenhouse gases
(GHGs) like CO₂, trapping heat in the atmosphere.
Case Study: China, the world’s largest CO₂ emitter, saw a dramatic
rise in emissions since its industrial boom in the 1990s. Despite
investing in renewable energy, it emitted over 10 billion metric
tons of CO₂ in 2022 (Global Carbon Project).
3. Melting Ice and Rising Sea Levels
Fact: Arctic sea ice is declining at a rate of 13% per decade, and
glaciers are shrinking worldwide.
Consequence: Global sea levels have risen by over 20 cm since
1900, and the rate is accelerating.
Case Study: In Bangladesh, sea-level rise and storm surges have
displaced over 1.5 million people, making it a hotspot for climate
refugees.
4. Extreme Weather Events Are Increasing
Fact: Global warming intensifies the frequency and severity of
heatwaves, floods, droughts, and hurricanes.
Evidence: The 2020 Australian bushfires burned over 18 million
hectares, killed 3 billion animals, and were fueled by record-
breaking heat and drought.
Case Study: Pakistan’s 2022 floods (caused by glacial melt and
extreme monsoon rains) affected 33 million people, submerged
one-third of the country, and caused $30 billion in damages.
5. Climate Change Impacts Agriculture and Food Security
Fact: Global warming affects crop yields, water availability, and
pest patterns.
Evidence: A 2°C rise could reduce wheat yields by 13% globally.
Case Study: Sub-Saharan Africa already experiences lower maize
and sorghum yields due to prolonged droughts, threatening food
security for millions.
6. Ocean Warming and Acidification
Fact: Over 90% of excess heat from global warming is absorbed by
the oceans, causing thermal expansion and coral bleaching.
Evidence: According to the IPCC, ocean heat content has reached
record highs in the last five years.
Example: The Great Barrier Reef (Australia) has experienced
multiple mass coral bleaching events since 2016, leading to loss
of biodiversity and collapse of marine ecosystems.
Fiction Refuted: Some claim the oceans are too vast to be
affected, but science shows ocean pH has declined by 30% since
the Industrial Revolution.
7. Biodiversity Loss and Species Extinction
Fact: Global warming disrupts ecosystems, pushing many species
beyond their survival limits.
Evidence: WWF’s Living Planet Report 2022 shows a 69% average
decline in wildlife populations since 1970.
Case Study: The golden toad of Costa Rica is believed to be the
first extinction directly linked to climate change and habitat
alteration.
8. Climate-Induced Migration
Fact: Rising sea levels, crop failures, and droughts are displacing
millions globally.
Evidence: The World Bank estimates that over 216 million people
could become climate migrants by 2050.
Example: In Sub-Saharan Africa, desertification and water scarcity
have led to internal displacement and conflict (e.g., Lake Chad
crisis).
Fiction Refuted: Deniers claim climate change is only an
environmental issue, ignoring its humanitarian and geopolitical
dimensions.
9. Economic Costs of Inaction
Fact: Climate change inflicts trillions in damages through disasters,
reduced productivity, and healthcare burdens.
Evidence: The Stern Review (UK, 2006) estimated the cost of
inaction on climate change at up to 20% of global GDP per year.
Case Study: In 2021, the U.S. suffered 20 separate billion-dollar
weather disasters, costing $145 billion in damages (NOAA
Report).
Fiction Refuted: Some claim mitigation is too costly, but inaction is
economically more devastating.
10. Public Health Threats
Fact: Rising temperatures increase the prevalence of vector-borne
diseases, malnutrition, and heat-related illnesses.
Evidence: The Lancet Countdown (2023) noted a 50% rise in
dengue, malaria, and cholera risk zones due to climate shifts.
Example: Pakistan and India’s heatwaves in 2022 killed hundreds
and overwhelmed hospitals with heatstroke cases.
Fiction Refuted: It's a myth that climate change only affects the
environment—it directly endangers human life.
🔹 FICTION: Common Myths and Misconceptions
1. ❌ “Climate change is natural, not man-made.”
Rebuttal: Natural climate cycles exist, but the current rate and
magnitude of warming are unprecedented and align with the rise
in GHG emissions since the Industrial Revolution.
Fact Check: Ice core data shows that current CO₂ levels (420 ppm)
are the highest in 800,000 years.
2. ❌ “Global warming stopped in the 2000s.”
Rebuttal: While warming slowed slightly due to oceanic heat
absorption (the so-called “hiatus”), global temperatures
continued to rise overall. The eight hottest years ever recorded
have all occurred since 2015.
3. ❌ “It’s cold outside, so global warming is a hoax.”
Rebuttal: Weather is not the same as climate. Local cold spells can
occur even as the global average temperature increases.
Example: The 2021 Texas snowstorm was linked to jet stream
instability caused by Arctic warming.
4. ❌ “Carbon dioxide is harmless; plants need it.”
Rebuttal: While CO₂ is necessary for photosynthesis, excess CO₂
traps heat. Also, extreme heat and drought reduce plant growth
despite higher CO₂.
Example: In Amazon forests, extreme heat events reduce carbon
absorption, turning forests into carbon sources.
5. ❌ “Climate scientists are uncertain or divided.”
Rebuttal: Over 97% of climate scientists agree that global
warming is real and caused by human actions.
Source: Multiple studies, including Cook et al. (2013), confirm this
overwhelming consensus.
6. ❌ “The climate has always changed—this is nothing new.”
Rebuttal: Yes, but natural changes happened over thousands of
years. The current warming is occurring within decades,
overwhelming natural systems.
Fact: The current rate of CO₂ increase is 100 times faster than
previous ice age cycles.
7. ❌ “Technology will fix everything eventually.”
Rebuttal: Relying on unproven future technology is risky. While
innovations like carbon capture and solar geoengineering are
promising, they are not fully scalable or tested for long-term
sustainability.
Example: The IPCC warns that mitigation through clean energy
and lifestyle change is irreplaceable.
8. ❌ “Only developed countries are responsible; poor nations can
pollute.”
Rebuttal: While historically rich countries emitted more, many
developing nations are now major polluters (e.g., India and
China). Climate change knows no borders.
Solution: The concept of Common But Differentiated
Responsibilities (CBDR) under UNFCCC promotes shared yet
proportionate action.
9. ❌ “Climate models are unreliable.”
Rebuttal: Climate models have accurately predicted warming
trends for decades, including Arctic melt and extreme rainfall
events.
Evidence: Models from the 1980s predicted current temperatures
with surprising accuracy (NASA 2019 review).
10. ❌ “There's nothing individuals can do.”
Rebuttal: Though governments play a major role, individual
actions add up: reducing meat consumption, conserving energy,
using public transport, etc.
Example: Denmark’s energy-efficient housing and cycling culture
reduce its per capita emissions significantly.
🔹 Real-World Global Responses (Mixed Progress)
1. Paris Agreement (2015)
Aim: Limit global warming to below 2°C, preferably 1.5°C.
Problem: Many countries are not meeting their Nationally
Determined Contributions (NDCs).
Example: The United States rejoined under President Biden in
2021, aiming for net-zero emissions by 2050.
2. Renewable Energy Growth
Fact: Solar and wind energy prices have dropped dramatically.
Example: In Germany, 51% of electricity in 2024 came from
renewables.
3. Fossil Fuel Subsidies Continue
Contradiction: In 2023, global fossil fuel subsidies hit a record $7
trillion (IMF report), undermining climate efforts.
🔹 Global Case Studies in Climate Action
🌿 Costa Rica
Runs on 99% renewable energy since 2015 and has doubled its
forest cover.
Model of eco-tourism and sustainable development.
☀️ Germany’s “Energiewende” (Energy Transition)

🌡️ Lesson 3: Climate Change
Harari identifies climate change as one of the three greatest existential
threats to humanity, alongside nuclear war and technological
disruption.
🔑 Key Points:
Climate change is a global problem that no single nation can solve
alone.
Nationalism is outdated in the face of planetary challenges.
Global problems need global solidarity.
Harari critiques political leaders who deny climate science or
sacrifice long-term environmental stability for short-term
economic gains.
He stresses the urgent need for collective responsibility,
technological innovation, and sustainable economic models.
🧪 Insightful Quote:
“As long as millions of individuals believe in nationalist myths, climate
change will continue to worsen.”
⚖️ Lesson 6: Civilization
Harari argues that our civilization is built on fragile foundations,
including ecological stability. If the environment collapses, so will our
economies, governments, and social systems.
He warns that if environmental tipping points are reached,
humanity may face mass migrations, food shortages, and social
unrest.
🌐 Lesson 20: Meaning
Harari reflects on how global warming challenges human meaning
systems—religion, nationalism, and capitalism—none of which alone
offer an effective solution.
He suggests embracing secular humility, science, and global
ethics to build a meaningful and sustainable future.
