Three Key Facts About Global Warming
Human Activities and Greenhouse Gas Emissions
One of the most critical facts about global warming is that it is primarily driven by human activities. The burning of fossil fuels such as coal, oil, and gas, along with large-scale deforestation, has led to significant emissions of greenhouse gases (GHGs) like carbon dioxide (CO2), methane (CH4), and nitrous oxide (N2O) into the atmosphere1 3 4. These gases trap heat by absorbing infrared radiation emitted by the Earth's surface, creating a "greenhouse effect" that warms the planet1 4. Since the industrial revolution, the concentration of CO2 in the atmosphere has increased by more than a third, significantly contributing to global warming3.
Impacts on Climate and Extreme Weather Events
Global warming has profound impacts on the climate, leading to more frequent and intense extreme weather events. These include heatwaves, increased rainfall, and a higher frequency of extreme climate events such as hurricanes and floods1 2. The warming of the Earth's surface also results in the melting of glaciers, ice caps, and sea ice, contributing to rising sea levels5 6. These changes pose severe risks to human health, food and water supplies, housing, and infrastructure3.
Economic Inequality and Global Disparities
Another significant fact about global warming is its role in exacerbating global economic inequality. Research indicates that global warming has likely increased economic disparities between countries, with poorer, hotter countries experiencing substantial declines in economic output due to the adverse effects of warming9. In contrast, some cooler, wealthier countries have seen economic benefits from the warming climate. This disparity highlights the uneven distribution of the impacts of global warming, where the countries least responsible for GHG emissions often suffer the most9.
Conclusion
In summary, global warming is a critical issue driven by human activities that emit greenhouse gases, leading to significant climate changes and extreme weather events. Additionally, it exacerbates global economic inequality, disproportionately affecting poorer nations. Addressing global warming requires urgent international action to reduce GHG emissions and implement effective mitigation and adaptation strategies.

Adopting mitigation and adaptation strategies simultaneously is the most effective solution to global warming, with CO2 being the controlling factor and water vapor being responsible for two-thirds of the warming.
Highly CitedAn apparent hiatus in global warming?
Global warming has not stopped; it is merely manifested in different ways, with sea-level rise being more relentless.
Highly CitedOn the detection of greenhouse warming
The recent unusually warm global temperature data and the four warmest years on record do not support the detection of greenhouse warming unless we attribute all warming to the greenhouse effect.
Global warming and carbon dioxide through sciences.
Increased atmospheric CO2 concentrations may stimulate plant growth and alter plant physiology, but the exact impact on global warming remains uncertain and scientific knowledge is insufficient to provide precise answers.
Literature ReviewHighly CitedGlobal warming has increased global economic inequality
Global warming has likely increased global economic inequality, with a 25-50% increase in between-country inequality over the past half century due to warming impacting economic growth in hotter, poorer countries and increasing in cooler, wealthier countries.
