    Global Warming

    Refers to the overallwarming of the planet,

    based on averagetemperature over the

    entire surface of the Earth

    Climate Change

    Refers to changes inclimate characteristics,including temperature,humidity, rainfall, wind,

    and severe weatherevents over long term

    Tools to Predict and ProjectChanges in the Climate

    A climate prediction or climate forecast is an attempt to produce an estimate ofthe actual evolution of the climate in the future.

    Climate Prediction

    Emissions scenarios describe future releases to the atmosphere of greenhousegases, aerosols, and other pollutants and, along with information on land use andland cover, provide inputs to climate models.

    Emissions Scenario

    A numerical representation of the climate system based on the physical, chemicaland biological properties of its components, their interactions and feedbackprocesses, and accounting for some of its known properties.

    Climate Model

    A climate projection is the simulated response of the climate system to a scenarioof future emission or concentration of greenhouse gases and aerosols, generallyderived using climate models.

    Climate Projection

    Why is Climate Change ScienceImportant?

    Sound weather data and forecasts

    important for:

    Short-term planning

    Emergency response

    Climate models help to forecast long

    term climate scenarios

    Important input for vulnerability assessments and

    adaptation planning Fosters climate resilient development and avoids mal-

    adaption

    Module Summary

    65

    Additional Resources

    Weather and climate are the results of complex interactions

    between anthropogenic and natural factors.

    Evidence of global climate change include higher average

    temperatures, changes in precipitation, ocean warming, ocean

    acidification, sea level rise, decreasing sea ice, and changes inphysical and biological systems.

    Observed climate change can be linked with the increase of

    greenhouse gase concentrations in the atmosphere since the

    industrial revolution. Global surface temperature change for the end of the 21st century

    is likely to reach 4C if no drastic mitigation actions are taken.

    Various sources of climate data exist that can support planning for

    climate change.
