Question

1. describe three

ways that climate
is changing now around the world.

1. what new factor is influencing earth’s

climate?

1. if we are in a time of global warming,

does that mean that every place on
earth is getting warmer every year?
why or why not?

Explanation:

Question 6

1. Rising Temperatures: Global average surface temperatures are increasing. Over the past century, the Earth's average temperature has risen, with more rapid warming in recent decades. This is measured by analyzing temperature records from weather stations, satellites, and other monitoring systems.
2. Melting Ice: Polar ice caps (like the Arctic and Antarctic ice sheets) and glaciers worldwide are melting at an accelerated rate. For example, the Arctic sea ice extent has been decreasing, and glaciers in mountainous regions (such as the Himalayas) are retreating. This melting contributes to rising sea levels.
3. Changing Precipitation Patterns: There are shifts in rainfall and snowfall distributions. Some regions are experiencing more intense rainfall events (leading to increased flooding), while others are facing more frequent droughts. For instance, parts of Africa and the Mediterranean are becoming drier, while areas like South Asia see heavier monsoonal rains.

The new factor influencing Earth’s climate is human activity, particularly the emission of greenhouse gases (like carbon dioxide, methane, and nitrous oxide) from burning fossil fuels (coal, oil, gas), deforestation, and industrial processes. These gases trap heat in the atmosphere, enhancing the greenhouse effect and causing global warming. Natural factors like solar radiation and volcanic activity have influenced climate historically, but human - induced greenhouse gas emissions are a relatively new (on a geological time scale) and dominant factor in recent climate change.

1. Climate vs. Weather Distinction: Global warming refers to the long - term trend of increasing global average temperatures. Weather is the short - term (daily, yearly) atmospheric condition of a specific place. A place's temperature in a given year can be affected by short - term weather phenomena (e.g., a strong El Niño or La Niña event, volcanic eruptions that temporarily cool the atmosphere, or local weather systems).
2. Regional Variability: Even in a warming world, some regions may experience cooling in certain years or over short periods. For example, changes in ocean currents (like the Atlantic Meridional Overturning Circulation) can affect regional temperatures. Also, local factors such as land - use changes (e.g., reforestation or urbanization) can impact the local climate in complex ways. However, the overall long - term trend across the globe is one of warming, but individual places may not warm every single year.

Answer:

• Rising global average temperatures.
• Melting of polar ice caps and glaciers.
• Altered precipitation patterns (more intense rains or droughts in different regions).
