Climate Change
By: Deja Jimenez
What is Climate Change?
Climate change refers to long-term shifts in temperatures and weather patters. Some shift are natural but since the Industrial era human activities have been the main driver of climate change. Scientists have proved beyond doubt that climate change is transforming the planet for the worse. Yet their work has mostly failed to spur governments to address the issue.
Climate Change is accelerating
Long-term observations confirm that our climate is now changing at a rapid rate. Over the 20th century, the average annual US temperature has risen by almost 1°F (0.6°C) (Lerner)
Warming Caused by Human Activity
There is strong scientific data from the IPCC, NASA and many academic journals that supports human activity plays a major role in climate change.
This is mostly due to Concentrations of carbon dioxide, methane, and nitrous oxide. Which is the highest concentrations recorded in 800,000 years.
The graph to the left provides evidence that atmospheric CO2 has increased dramatically since the Industrial Revolution

Consequences of Climate Change
Overall Consequences of Climate Change: included more rain snow, flood, droughts and increase melting glacier, humidity levels increasing and more natural disasters occurring all over the world.
Effects on Ecosystems:
Coral systems and other unique ecosystems cannot handle higher temperatures well
Wildfires will increase
Up to 30% of species will be at increased risk for extinction due to the rapid changes in their ecosystems
Effects in North America
Warming in western mountains: several effects
Heat waves will increase in number, length, and intensity
Coastal communities will be affected by increased flooding and storms
What is being done about Climate Change?
Many Climate mitigation plans have failed
“Few current plans to limit global warming (e.g., the Paris Accords) are on target, but the AR6 Science report also asserts that even if current plans to limit planet-warming greenhouse gas “emissions were performing as expected, many perils related to climate change can not be avoided or mitigated over the next few decades” (Lerner)

Action Needs To Be Taken Before Its Too Late!
Many researchers and scientist agree that climate change is one of the most contentious issues facing humanity
Scientist warn that quick and major action is needed to avoid major increases in sea levels, extreme weather and other effects.
Scientist warn that major and irreversible consequences will occur if Earth undergoes a 1.5 degree celcius rise in global temperature, right now we are at 1.1.
