Ciencia climática 101

The document explains the distinction between weather and climate, the human-driven causes of global warming, and the resulting increase in extreme weather events. It highlights the disproportionate impact of climate change on marginalized groups and outlines necessary solutions, including transitioning to renewable energy and improving resource efficiency.

• Global warming refers to the rise in average global temperatures since the 19th century, while climate change is a broader term encompassing global warming and its resulting effects, such as sea-level rise, melting glaciers, and increased frequency of extreme weather.
• Since 1900, the planet has warmed by approximately 1.1 degrees Celsius (1.9 degrees Fahrenheit), with the last seven years (as of 2022) being the hottest on record.
• Current global warming is caused by human activities—primarily the burning of fossil fuels and deforestation—which create an unnecessary second layer of heat-trapping gases in the atmosphere.
• Climate change intensifies extreme weather events, including more prolonged heatwaves, heavier precipitation leading to inland flooding, more severe droughts, larger wildfires, and stronger tropical cyclones due to warmer oceans.
• Climate change disproportionately affects indigenous groups, communities of color, and the poor, despite these groups contributing the least to emissions; for example, the wealthiest 10% of the global population produces over half of the world's carbon emissions.
• The World Health Organization estimates that between 2030 and 2050, uncontrolled climate change could cause approximately 250,000 additional deaths annually from malnutrition, malaria, diarrhea, and heat stress.
• Effective climate solutions must include generating energy from clean sources (specifically wind and solar), reducing emissions across manufacturing, energy, agriculture, and transport, increasing resource efficiency, and removing carbon from the atmosphere.
