How is climate different from weather? Weather can change from hour-to-hour, day-to-day, and season-to-season. It may rain for an hour and then become sunny and clear. It includes wind, temperature, humidity, atmospheric pressure, cloudiness, sunshine and precipitation. Climate is the average weather for a particular region over a long time period. Climate describes the total of all weather occurring over a long period of years in a given place. This includes average weather conditions, regular weather seasons (winter, spring, summer, and fall), and special weather events (like tornadoes and floods).
How are climate and weather related? Climate is weather that happens over a period of time, Weather is now. They are both related because they both have changes in the weather. Plus they are use to refer what are the temperatures in a country. What is the green house effect? The greenhouse effect is the rise in temperature that the Earth experiences because certain gases in the atmosphere (water vapor, carbon dioxide, nitrous oxide, and methane, for example) trap energy from the sun.
Without these gases, heat would escape back into space and Earth’s average temperature would be about 60? F colder. Because of how they warm our world, these gases are referred to as greenhouse gases. How is amplified warming different from natural warming? Normal warming is mostly caused by natural gases. Amplified warming is mostly caused by heat changes that cause mutations of climate. Also amplified is more spread around the world than normal warming. What factors are most responsible for significant changes in the climate?
The major factors are carbon dioxide, deforestation, burning of fossil fuels, road vehicles, pollution, volcanic eruptions, sunspots, water vapor, methane, nitrous oxide, etc. Which of these are natural causes and which are driven by human activity? Most of these causes, like pollution and road vehicles, are cause by human activity and they are some of the major causes of the change in the Earth’s climate. Volcanic eruptions and sunspot are natural causes that are putting our world in danger too. How will humans be impacted by changes in the climate?
The sea levels will raise and land will be lost, seas temperature are going to rise, there will be lost of rain, a lot of dry places, lots of diseases, agricultural places and lots of animals die because of these problem. How will global warming change ecosystems and the environment? Environment Impacted by Global Warming: As the surface of the Earth heats up, unseasonal temperatures and weather phenomenon have become the norm in many areas of the world. The changes in the temperature and weather patterns have already begun to cause changes in land that was once able to produce or grow food.
More and more areas are experiencing drought, which has caused a lack of food in areas, which are in great need of water. Global warming has also had the opposite effect in some areas creating catastrophic flooding and other weather phenomenon that has impacted the environment in a disastrous way. Ecosystems Impacted by Global Warming: The ongoing concern right now is the rise in sea level due to glacial ice melting and causing sea level to rise. The rise in sea level could have the potential to not only swallow land along the coast, but to dump salt water in otherwise fresh water habitats such as marshes and wetlands.
The infiltration of this salt water will create an unstable environment for many of the animals that call the fresh water habitats their home. Just a slight change in the ecosystem can greatly affect the symbiotic relationships between the animals and organisms that are native to these areas. How do CO2 emissions levels differ from country to country? In some countries there is a lot of power stations, motor vehicles and industries. These things send a lot of CO2 emissions to the atmosphere. This is why economically develop countries have more CO2 than others.
Which countries produced the most total CO2 in 2000? In 2000, the United States, Canada and Australia were among the leading CO2 emitters per capita in the industrial world. China and the developing world had the smallest emissions per capita. Which countries are expected to see a significant increase in their CO2 emissions by 2025? In 2025, the United States, Canada and Australia are still projected to be among the leading CO2 emitters per capita. China and the developing world are projected to have the lowest emissions per capita.
