Basic Knowledge on Climate Change

What is climate change?

Climate change refers to a change in the state of the climate that can be identified (e.g., by using statistical tests) by changes in the mean and/or the variability of its properties, and that persists for an extended period, typically decades or longer. Climate change may be due to natural internal processes or external forcing, or to persistent anthropogenic changes in the composition of the atmosphere or in land use.

Causes of climate change

  • Natural factors: changes in solar, slowly changing of earth orbit around the sun, changes sea and air currents.
  • Human activities: burning of fossil fossil, deforestation, land encroachment for agriculture, urban expansion, landfill etc.

Greenhouse Effect

A greenhouse is a house with transparent plastic or glass roof and walls that is built to grow vegetables, flowers or other plants in temperate and colder countries. A greenhouse protects and provides heat to plants: its roof and walls allow sunlight to enter and prevent heat from escaping. This effect is known as the "greenhouse effect".

Greenhouse Gases (GHGs)

The earth's atmosphere contains some gases known as greenhouse gases, which occur naturally: water vapor, carbon dioxide, methane (CH4), nitrous oxide (N2O), and ozone (O3). Anthropogenic emission included CO2, N2O, and CH4, hydrofluorocarbons (HFCs), sulfur hexafluoride (SF6), perfluorocarbons (PFCs).

Climate Change Adaptation

Is the process of adjustment to actual or expected climate and its effects. In human systems, adaptation seeks to moderate harm or exploit beneficial opportunities. In natural systems, human intervention may facilitate adjustment to expected climate and its effects.

Climate Change Mitigation

Is a human intervention to reduce the sources or enhance the sinks of greenhouse gases. Mitigation activities included afforestation, water and electricity saving, reduce and reuse of solid waste, biodigester and solar energy.

The new normal: facing climate change

Source: Phnom Penh Post,

 

Last year’s drought caused a nationwide crisis, with harvests ruined, forest fires raging and many rural families struggling to feed themselves. As experts take stock of the impact, news of another potential El Niño raises a question: Is Cambodia prepared for the next drought?

For Cambodia, the El Niño that began in 2015 hit hard, causing a two-year drought that jeopardised the health, food security and finances of millions of people.

Act Together to Protect Cambodia From Climate Change

Source: The Cambodia Daily, 4 January 2016

It’s time for us to discuss, plan and act together to protect Cambodia and our children from climate change. We must address climate change from the heart, and not treat it as an abstraction or a problem for other countries.

The recent landmark international climate change agreement signed in Paris is a turning point for the planet. It’s the best chance to keep Earth hospitable to human life. Countries agreed to globally coordinate action on climate change; embraced a common goal to strive for a limit of 1.5 degrees Celsius above preindustrial levels; and stated that emissions should peak “as soon as possible” and then rapidly decline.
