Study Notes
Global Warming
- The primary cause of global warming since the late 19th century is the widespread burning of fossil fuels, leading to large-scale emissions of heat-trapping carbon dioxide into the atmosphere.
Temperature Increase
- Average surface temperatures have increased by approximately 1°C compared to a century and a half ago.
Ice Melt and Sea Level Rise
- Trillions of tons of ice have melted from the world’s ice sheets and glaciers, evidenced by glaciological and satellite data.
- Sea levels have risen by approximately 15-20 cm since 1900, according to tide gauges and other instruments.
Climate Change Effects
- Climate change has caused shifts in bird species' migration patterns and breeding seasons, as documented by ornithologists.
- Rainfall data have shown an increase in extreme precipitation events and altered patterns due to climate change.
- The top layer of the world’s oceans has warmed, with evidence showing a significant increase in ocean temperatures.
Scientific Consensus
- Scientists have reached an overwhelming consensus that global warming is real, primarily caused by human activities, and a serious threat to the environment.
