1. Assume that you have 100 years of continuous temperature records from your local weather service office. Discuss some of the difficulties you might have trying to determine whether average temperatures have increased during this period. 2. What are meant by the terms positive and negative feedback mechanisms? Give an example of a process that would be considered a positive feedback mechanism during a period of warming on the earth. Can you think of a negative feedback mechanism? 3. Discuss

our climate has changed in the past century and will continue to change‚ affecting both biological and physical systems. In the past 50-100 years British Columbia has noticed an annual precipitation increase of about 20 percent‚ and lost around 50 percent of its snow pack annually. Also with the increased precipitation and faster melt the province has been more susceptible to floods in the Fraser Valley‚ Interior and throughout British Columbia. These floods and early melt are expecting to increase

MEANING OF GLOBAL WARMING Global warming is defined as an increase in the average temperature of the Earth’s atmosphere‚ especially a sustained increase great enough to cause changes in the global climate. The term global warming is synonymous with Enhanced green house effect‚ implying an increase in the amount of green house gases in the earth’s atmosphere‚ leading to entrapment of more and more solar radiations‚ and thus increasing the overall temperature of the earth. (71 words) EFFECT OF GLOBAL

it absorbs not only the long wave terrestrial radiation‚ but also a part of the incoming solar radiation. Thus‚ it is an important control in regulating the energy transfer through the atmosphere. Water vapour is the source of all clouds and precipitation. Through the condensation of water vapour‚ vast amount of energy is released into the atmosphere in the form of latent heat of condensation‚ the

strong they say it can be up to 70mph some airports have been shut. Windy rainy days but still very humid. Sunny and windy days but cold. Climate measures the average pattern of variation in temperature‚ humidity‚ atmospheric pressure‚ wind‚ precipitation. Climate is different from weather‚ in that weather only describes the short-term conditions of these variables in a given region. Climate change means the average temperature across the world either increases or decreases. It happens naturally

Dominique Bowie Climate Change and the California Wildfires Your Class Instructor name August 13th 20 10 The world around us is forever changing. Things don’t ever quite stay the same do they? Over the year there have been changes in politics‚ traditions‚ and even television. The list could go on and on. With that being said‚ there is one element of the world where change could drastically impact our futures and that of our loved ones. Our surrounding Environment is becoming more complicated

weather patterns also affects a human’s well-being exponentially. Due to the alteration of weather‚ the number of droughts and floods will drastically increase. Evidence to this would be how‚ over the past century‚ random and rapid bouts of precipitation have come to be more frequent. Along with these natural disasters come death‚ starvation‚ and a redevelopment and an extended range of infectious diseases. This would be problematic seeing as once a disease settles itself in a community‚ that disease

1. Is a temperature inversion more likely to form on a calm or a windy night? Why? A temperature inversion is most likely to form on a calm night. Windy nights are not ideal for an inversion to occur since an inversion is considered a stable layer of atmosphere as well as due to the wind mixing the air to even out the density‚ remembering cold air is denser than warm air so it will flow downhill and pool in a valley. 2. What are the various methods used to protect sensitive crops from damaging
