Answer:
What is Climate Change?
Climate change is the change in the weather that would normally occur in a location. One example of climate
change could be a change in the amount of rain or snow a place normally gets in a year. Another example of
climate change could be a drop in a place's usual temperature for a month or vice versa. Climate change is also
related to a change in Earth's climate, such as a change in Earth's usual temperature, or a change in where rain
and snow usually fall on Earth. Weather can change in just a few hours, while climate takes hundreds to
millions of years to change.
How is Climate Change Caused?
Gasses that released in the atmosphere block heat from escaping. Air pollution is the main cause of the
rise in temperature over the past century. The increase in industrialization in different countries of the
world and the burning of more fossil fuels in the engines of vehicles and jets are the main reasons for
increasing global temperature. On Earth, human activities are changing the natural greenhouse. Over the
last century, the burning of fossil fuels such as coal and oil has increased the concentration of
atmospheric carbon dioxide (CO2). This happens because the coal or oil burning process combines
carbon with oxygen in the air to make CO2. To a lesser extent, the clearing of land for agriculture, industry,
and other human activities has increased concentrations of greenhouse gases.
How does Climate Change Affect Us?
While it can sometimes be subtle, climate change affects Earth and its residents every day. Climate extremes,
such as droughts, floods, and extreme temperatures, can lead to crop losses and threaten the livelihoods of
agricultural producers and the food security of communities worldwide. Depending on the crop and
ecosystem, weeds, pests, and fungi can also thrive under warmer temperatures, wetter climates, and
increased CO2 levels, and climate change will likely increase weeds and pests.
How Do We Know Climate Change is Real?
“Scientists have been observing Earth for a long time. They use NASA satellites and other instruments to collect
many types of information about Earth's land, atmosphere, ocean and ice. This information tells us that Earth's
climate is getting warmer” (climatekids.nasa.gov) shows that besides your own observations on the Earth over
the years, scientists around the globe have been able to detect the changes in Earth’s climate, along with the
causes of climate change.
Why Should I Care About Climate Change?
Like stated in previous slides, climate change has numerous effects on Earth’s inhabitants and environment.
Some of the greatest impacts on Earth have been increased heat, droughts, increase in pests, rising sea levels,
and melting glaciers. Scientists have predicted that there are “Only 11 Years Left to Prevent Irreversible Damage
from Climate Change” (un.org), as of March of 2019. Earth’s ambient temperature has been on the rise for
hundreds of years, which is a change in the climate that we should strive to slow down
