Climate |
The long term pattern of weather in a particular area. Weather can change from hour to hour, day today, month to month or even year to year. A region's weather patterns, usually tracked for at least 30 years, are considered its climate. |
|
Albedo |
A measure of how much light that hits a surface is reflected without being absorbed. Something that appears white reflects most of the light that hits it and has a high albedo, while something that looks dark absorbs most of the light that hits it, indicating a low albedo. |
|
Greenhouse effect |
A natural process that warms the Earth's surface. When the Sun's energy reaches the Earth's atmosphere, some of it is reflected back to space and the rest is absorbed and re radiated by greenhouse gases. |
|
Global warming |
Describes the current rise in the average temperature of Earth air and oceans. Global warming is often described as the most recent example of climate change. |
|
IPCC |
The intergovernmental panel on climate change Is the leading International body for the assessment of climate change. Reviews and assesses the most recent scientific comic technical and socio economic information produced worldwide relevant to the understanding of climate change. |
|
Weather vs climate |
Climate is the consistent trends and variability in weather over the long term. Whether on the other hand, is the short term condition of the atmosphere at any given place and time. |
|
What type of atmospheric lifting is responsible for precipitation patterns |
All 4 types of atmospheric lifting are responsible |
|
Describe tropical climate region |
High installation, equatorial low pressure, warm surface currents. Types of lifting include convergent, convectional, and orographic. |
|
Describe dry climate region |
High installation, subtropical high air pressure. Cold surface current. Types of lifting include rain shadows from orographic lifting |
|
Describe polar/Highland region |
Low installation, high albedo, polar high air pressure. Cold surface current, atmospheric lifting types include orographic lifting. |
|
Climate change trends |
In the past, long term natural shifts between glacial and interglacial. In the present, rapid shifts inconsistent with natural cycles show climate change. |
|
Climate change indicators |
Increasing temperatures over land and ocean surfaces, increasing sea surface temperatures and the ocean heat content, melting glacial ice and sea ice, rising sea levels, and increasing atmospheric water vapour. |
|
Ice melt: sea ice |
11 to 13% loss of ice decreases ocean albedo and salinity |
|
Ice melt: Glacial |
short term flooding and long term river drought, decrease albedo and ocean salinity and sea level rise |
|
Ice melt, permafrost |
decreased albedo and tundra absorbs more insulation, increase in carbon dioxide and methane. |
|
Sea level rise |
Melting glaciers and rising temperatures increase volume, increasing storm surge and sailing intrusion into aquifers. |
|
Atmospheric water vapor |
Floods, droughts inconsistent with seasonal expectations, higher temperatures, sea levels, and evaporation rates, stronger and more frequent hurricanes, higher storm surge. |
|
What natural fluctuations account for pre anthropogenic climate shifts on our planet? |
Continental landmasses, orbital cycles, milankovitch cycles, solar variability, maunder minimum, atmospheric gases, and El nino. |
|
Continental land masses |
Play tectonic movement over millions of years. Continental position alters ocean current, albedo, and atmospheric lifting |
|
Orbital cycles |
A 100,000 year shift in elliptical orbit, 41,000 and 26,000 year axial tilt and wobble. |
|
Milankovitch cycles |
Changes in albedo, ocean circulation, and greenhouse gases. |
|
Atmospheric gases |
Outgassing (h20) and volcanos (co2). 2 billion years H20 quantity equilibrium, 290 million years modern atmospheric composition. Aerosols increase albedo for months to years. |
|
What are the 4 major greenhouse gases? |
Carbondioxide, methane, nitrous oxide, and halogenated gases |
|
Carbon dioxide anthropogenic sources |
Burning fossil fuels, deforestation, and cement |
|
Methane anthropogenic sources |
Livestock, mining, and burning vegetation |
|
Nitrous oxide anthropogenic sources |
Burning fossil fuels, fertilisers, and wastewater treatment |
|
Hallogenetic gases |
Refrigerants and isolation foams |
|
IPPC |
The International plant protection convention is a 1951 multilateral treaty overseen by the United Nations food and agriculture organisation that aims to secure coordinated, Effective action to prevent and to control the introduction and spread of pests of plants and plant products |
|
Kyoto protocol |
Is an International treaty which H stands the 1992 United Nations framework convention on climate change that commits state parties to reduce greenhouse gas emissions, based on the scientific consensus that global warming is occurring and that human made co2 emissions are driving it |
|
Paris agreement |
The Paris agreement's central aim is to strengthen the global response to the threat of climate change by keeping a global temperature rise this century while below 2゚C above preindustrial levels and to pursue efforts to limit the temperature increase even further to 1.5゚C |
|
Carbon disclosure project |
An International nonprofit organisation based in the United Kingdom, Germany, and the United States of America that helps companies and cities disclose their environmental impact |
