Understanding the basics of climate change

The greenhouse effect and global warming

1. The Earth's global average temperature has risen by approximately 1.1 to 1.2°C above pre-industrial levels (1850-1900).
2. The past decade (2015-2024) has been the warmest on record globally.
3. Human activities, primarily the burning of fossil fuels, have been the main driver of climate change since the 1800s.
4. The greenhouse effect is a natural process where certain atmospheric gases trap heat, vital for sustaining life on Earth.
5. Global warming refers specifically to the long-term heating of Earth's climate system, while climate change encompasses broader shifts like sea level rise and extreme weather events.

Scientific consensus and evidence

1. The Intergovernmental Panel on Climate Change (IPCC) provides comprehensive scientific assessments on climate change, informing global policy.
2. Over 97% of actively publishing climate scientists agree that climate-warming trends are extremely likely due to human activities.
3. Ice cores reveal atmospheric composition and temperatures from hundreds of thousands of years ago, showing current CO2 levels are unprecedented in recent geological history.
4. Oceans have absorbed over 90% of the excess heat trapped by greenhouse gases, leading to thermal expansion and contributing to sea level rise.
5. Satellite observations provide extensive, continuous data on changes in ice sheets, glaciers, sea levels, and atmospheric temperatures, offering robust evidence of climate change.

Key greenhouse gases

1. Carbon dioxide (CO2) is the primary greenhouse gas emitted through human activities, mainly from burning fossil fuels for energy and transport.
2. Methane (CH4) is a potent greenhouse gas, far more effective at trapping heat than CO2 over a 20-year period, though it has a shorter atmospheric lifespan.
3. Nitrous oxide (N2O) is released from agricultural and industrial activities, as well as fossil fuel combustion, and is a long-lived greenhouse gas.
4. Fluorinated gases, such as HFCs, PFCs, and SF6, are synthetic, powerful greenhouse gases used in various industrial applications, with very high global warming potentials.
5. Pre-industrial atmospheric CO2 concentrations were around 280 parts per million (ppm), compared to over 420 ppm today.

Global impacts of climate change

Rising temperatures and extreme weather

1. Global heatwaves are becoming more frequent, longer-lasting, and more intense, posing significant health risks.
2. The Arctic is warming at least twice as fast as the global average, accelerating ice melt and affecting global weather patterns.
3. Glaciers and ice sheets worldwide are shrinking at an accelerated rate, contributing significantly to sea level rise.
4. Climate change is increasing the intensity and frequency of heavy rainfall events in many regions, leading to more severe flooding.
5. Prolonged droughts are expanding in duration and severity across many parts of the world, impacting water resources and agriculture.

Sea level rise and ocean acidification

1. Global mean sea level has risen by about 20 cm since 1900, with the rate accelerating in recent decades.
2. Thermal expansion of ocean water, as it warms, is a major contributor to sea level rise.
3. The melting of ice sheets in Greenland and Antarctica is adding vast quantities of water to the oceans, further accelerating sea level rise.
4. Ocean acidification, caused by the absorption of excess CO2, threatens marine ecosystems, especially shellfish and coral.
5. Coral reefs are experiencing widespread bleaching events due to rising ocean temperatures, leading to significant biodiversity loss.

Biodiversity loss and ecosystem changes

1. Climate change is a significant driver of species extinction risk, altering habitats faster than many species can adapt.
2. Many plant and animal species are shifting their geographic ranges towards cooler poles or higher altitudes in response to warming temperatures.
3. Changes in phenology, such as earlier flowering times and altered migration patterns, disrupt ecological interactions and food webs.
4. The frequency and intensity of wildfires are increasing in many regions, devastating forests, ecosystems, and human settlements.
5. Agricultural yields are being impacted by changes in temperature, rainfall, and increased pest outbreaks, threatening food security.
