It was cool the day before, but now the temperature is climbing. She turns to look at Aaron and Gracie and shakes her head back and forth with gloom. Aaron and Gracie look at each other with confusion. If you were on the bus with these people, how would you respond? If yesterday was cool and today is warm, could that be due to global warming?
Are weather and climate the same or different? How would you respond to the people on the bus?
Science / Weather and Climate
How would you figure out what weather is normal for that time of year and that location? Can you think of a way that we can use weather data to figure out how climate is changing?
Extensions Use this activity before an exploration of global climate change. To get started, have students look for local climate change projections on Weather Underground. Do this exercise in cooperation with another school in a different geographic location comparing weather data to emphasize regional climate differences. Weather is different in different parts of the world and changes over minutes, hours, days and weeks.
The weather events happening in an area are controlled by changes in air pressure. Air pressure is caused by the weight of the huge numbers of air molecules that make up the atmosphere.
Typically, when air pressure is high, skies are clear and blue. The high pressure causes air to flow down and fan out when it gets near the ground, preventing clouds from forming. When air pressure is low, air flows together and then upward where it converges, rising, cooling, and forming clouds.
Remember to bring an umbrella with you on low pressure days because those clouds might cause rain or other types of precipitation. The average weather pattern in a place over several decades is called climate. Different regions have different regional climates.
It is the average weather in a place over thirty years. To describe the regional climate of a place, people often tell what the temperatures are like over the seasons, how windy it is, and how much rain or snow falls. The climate of a region depends on many factors including the amount of sunlight it receives, its height above sea level, the shape of the land, and how close it is to oceans. Since the equator receives more sunlight than the poles, climate varies depending on its distance from he equator.
Notice how the white bars stay generally, but not exactly within the range of the average high temperature 87 F and the average low temperature 56 F. Global climate is a description of the climate of a planet as a whole, with all the regional differences averaged. Overall, global climate depends on the amount of energy received by the Sun and the amount of energy that is trapped in the system.
These amounts are different for different planets. Scientists who study Earth's climate and climate change study the factors that affect the climate of our whole planet.
While the weather can change in just a few hours, climate changes over longer timeframes. Today, climates are changing.
Adaptation comes at a cost. Adaptive responses vary in effectiveness, as demonstrated by current efforts to cope with climate variability. The systemic nature of climate impacts complicates the development of adaptation policy.
Climate change adaptation
Maladaptation can result in negative effects that are as serious as the climate-induced effects that are being avoided. Many opportunities for adaptation make sense whether or not the effects of climate change are realized.
Scheraga and Grambsch make it clear that climate change policy is impeded by the high level of variance surrounding climate change impacts as well as the diverse nature of the problems they face. Adaptation can mitigate the adverse impacts of climate changebut it will incur costs and will not prevent all damage. Furthermore, these problems both the causes and effects of climate change are occurring on a global scale, which has caused the United Nations to lead global policy efforts such as the Kyoto Protocol and Paris Agreementin addition to creating a body of research through the IPCCin order to create a global framework for adapting to and combatting climate change.
Environmental Protection Agencyidentifies the following criteria that policy makers should use in assessing responses to global warming: Will the initiative yield benefits substantially greater than if the resources were applied elsewhere?
Is the strategy reasonable for the entire range of possible changes in temperatures, precipitation, and sea level? Would the strategy be successful if implementation were delayed ten or twenty years? Does the strategy require minimal resources? Does the strategy unfairly benefit some at the expense of other regions, generations, or economic classes?

Is the strategy acceptable to the public? Can it be implemented with existing institutions under existing laws? Unique or Critical Resources: Would the strategy decrease the risk of losing unique environmental or cultural resources? Would the proposed strategy increase or decrease the risk of disease or injury? Does the policy support other national state, community, or private goals?
Does the strategy minimize governmental interference with decisions best made by the private sector? Differing time scales[ edit ] Adaptation can either occur in anticipation of change anticipatory adaptationor be a response to those changes reactive adaptation.
Some adaptation measures, however, are anticipating future climate change, such as the construction of the Confederation Bridge in Canada at a higher elevation to take into account the effect of future sea-level rise on ship clearance under the bridge. For example, the expansion of irrigation in Egypt into the Western Sinai desert due to a period of higher river flows is a maladaptation when viewed in relation to the longer term projections of drying in the region .
Adaptations at one scale can also create externalities at another by reducing the adaptive capacity of other actors. This is often the case when broad assessments of the costs and benefits of adaptation are examined at smaller scales and it is possible to see that whilst the adaptation may benefit some actors, it has a negative effect on others.
Strengthening these local techniques and building upon them also makes it more likely that adaptation strategies will be adopted, as it creates more community ownership and involvement in the process. Some have begun to take steps to adapt to threats intensified by climate change, such as flooding, bushfires, heatwaves, and rising sea levels.
Its efforts include not only making buildings less prone flooding, but taking steps to reduce the future recurrence of specific problems encountered during and after the storm: Those societies that can respond to change quickly and successfully have a high adaptive capacity.
For example, the adaptive capacity in Western Europe is high, and the risks of warmer winters increasing the range of livestock diseases was well documented, but many parts of Europe were still badly affected by outbreaks of the Bluetongue virus in livestock in Adaptive capacity is the ability of a system human, natural or managed to adjust to climate change including climate variability and extremes to moderate potential damages, to take advantage of opportunities, or to cope with consequences.
