Study Notes
Global Warming Overview
- Global annual temperature has increased by over 1°C (2°F) since the Industrial Revolution.
- Average temperature rise from 1880 to 1980 was 0.07°C (0.13°F) every decade; since 1981, the rate has increased to 0.18°C (0.32°F) per decade.
- Nine of the ten warmest years on record have occurred since 2005, with the five warmest years since 2015.
- Claims of a “pause” or “slowdown” in global warming have been disproven by numerous studies.
Impact of Global Warming
- Global warming is already causing harm, with significant effects such as extreme droughts, wildfires, floods, and tropical storms.
- Vulnerable populations, including the economically marginalized and people of color, are disproportionately affected, facing increased poverty, displacement, and hunger due to climate change.
- Scientists advocate for limiting global warming to 1.5°C by 2040 to mitigate severe future consequences.
Causes of Global Warming
- Global warming is caused by an accumulation of greenhouse gases (GHGs) such as CO2, methane, and nitrous oxide in the atmosphere, leading to a greenhouse effect.
- GHGs absorb sunlight and solar radiation that would otherwise escape into space, trapping heat.
- Human activities, particularly the burning of fossil fuels (coal, oil, gasoline, natural gas), are the primary contributors to current warming.
- In the U.S., transportation accounts for 29% of GHG emissions, followed by electricity production at 28% and industrial activity at 22%.
Solutions and Commitments
- Significant emissions reductions are required globally, with a target of 40% reduction by 2030 to avoid severe climate impacts.
- The 2015 Paris Climate Agreement includes commitments by countries to lower emissions through new policies and standards.
- Transitioning from fossil fuels to renewable energy sources (like wind and solar) and increasing energy efficiency in buildings are key strategies for decarbonization.
- Immediate action and collective efforts are essential to achieve climate targets effectively.
