Study Notes
Climate Change and Society
- Climate change is the alteration of weather patterns in a place over a long time.
- Weather refers to atmospheric conditions, including temperature, humidity, precipitation, wind pressure, and the appearance of storms, for a particular time.
- Climate is the average weather of a place over a long time (e.g., 30 years or more). This includes average precipitation, temperature, humidity, and wind velocity.
- Climate is predictable.
- The changing climate of the Earth is well-supported by scientific evidence.
- Modern climate data are collected using advanced technology, primarily satellites.
- Paleoclimate data include information from thousands or millions of years ago; these are collected from various sources (e.g., ice cores, soil, trees).
- A climate scientist gathers and analyzes data from the atmosphere, oceans, and land; creates computer models to simulate climate effects; and studies past climates to understand possible future changes.
- The requirements for a career as a climate scientist typically include a Bachelor's or Master's degree in atmospheric science or a related field (e.g., physics, chemistry, geology, engineering); proficiency in technical writing, mathematics, and computer modeling; and research experience.
- Greenland and Antarctic Ice sheets are monitored using remote sensing (GRACE and GRACE Follow-on satellites). These methods use the changes in the distances between orbiting satellites to track ice sheet mass changes.
- Mass balance is the difference between the mass gained (snow deposition) and lost (melting, calving) by ice sheets.
- A negative mass balance indicates warming and changing climate.
- The IPCC (Intergovernmental Panel on Climate Change) is a United Nations body that assesses scientific research related to climate change.
- The IPCC's 5th assessment report stated a 95% certainty about the role of human activities in the 21st century's climate change.
- The greenhouse effect is a well-supported theory for how the Earth's atmosphere blankets the planet. Heat-absorbing gases (e.g., CO2, CH4) help maintain life-sustaining temperatures on Earth.
- Measuring CO2 concentrations in ice cores has shown that current levels are unprecedented in the last 800,000 years.
- Though overall Antarctica is losing more ice mass than it is gaining, some portions have shown increasing ice mass during the last 15 years.
- Reconstructing temperature and climate data over long periods (e.g., thousands to millions of years) is necessary to determine the extent to which human activities are influencing climate shifts. Scientists use various techniques, such as loess soil and ice cores, to study ancient climates.
- Climate data from ice cores can be used to study past temperatures. Data includes the annual layers of ice, which are light (summer) and dark (winter), to determine the age of the core, and oxygen and hydrogen isotope ratios to measure past temperatures.
- There are several international and national policies and programs designed to address climate change mitigation (reducing greenhouse gas emissions). The Kyoto Protocol and the Paris Climate Agreement are examples of global-level efforts. The Philippine Climate Change Commission is an example of a country-level approach. Various projects funded by the Green Climate Fund aim to support the Philippines in tackling climate change.
