Flashcards

Greenhouse gases

Gases in the Earth's atmosphere that trap heat, letting sunlight in but preventing some heat from escaping back into space. This process keeps the planet warm enough for life.

Kiribati

A Pacific atoll country, mostly made up of low-lying islands and atolls, vulnerable to rising sea levels due to global warming.

Global sea level rise

The increase in the average level of the world's oceans. Kiribati, and other low-lying islands, are particularly vulnerable.

Pacific Ocean warming

The Pacific Ocean is warming at a rate 15 times faster than average over the past 100 years, exacerbating global warming effects.

Study Notes

Global Warming in Kiribati

  • Greenhouse gases trap heat in Earth's atmosphere, preventing some heat from escaping back into space, maintaining a livable temperature.
  • Key greenhouse gases include carbon dioxide, fluorinated gases, methane, and nitrous oxide.
  • Kiribati is a Pacific atoll country with 119,000 people spread across 33 atolls, 20 of which are inhabited.
  • Maximum altitude is 1.8m above sea level.
  • Global sea levels have risen 10.3cm between 1993 and 2024 (3.32cm per year).
  • The Pacific Ocean absorbs more heat than other oceans (0.9°C warming in the last 100 years, 15x faster than the past 10,000 years).
  • Sea levels are projected to rise by 0.6 meters by 2100, primarily due to existing greenhouse gas emissions.
  • Kiribati is preparing for rising sea levels by purchasing land elsewhere, relocating people, or establishing floating cities.
  • Kiribati is not alone; other island nations like the Maldives, Marshall Islands, Tuvalu, Funafuti, and Tokelau are also facing similar challenges.

World Global Warming

  • Three-quarters of large cities are located on coasts.
  • Human understanding of gravity dates back to 1666.
  • Joseph Fourier, in the 1820s, was among the first to understand that Earth's gravity creates an ozone layer.
  • Svante Arrhenius, in 1886, was the first to suggest that fossil fuel combustion could lead to global warming.
  • The IPCC was established in 1988.
  • Global warming is defined as a 30-year average increase in air and sea surface temperatures, compared to pre-industrial (1850-1900) averages.
  • The IPCC 2021 report indicates that human activity has warmed the planet by approximately 1.1°C since the Industrial Revolution.
