Recent climate change, which has occurred during the modern instrument era, is the focus of this module. It is through the lens of long-term climate change (occurring on thousands to millions of years) that we will view earth’s current climate and recent climate change. The goal is to investigate how the principles listed above are shaping current climate events
Learning objectives
After reading this module, students should be able to
assess long-term global temperature records and place recent climate change into the context of historical temperature observations
explain how changes in the Sun's energy output have impacted the last 1300 years of global temperature records
analyze the human impact on the planetary albedo and relate these changes to recent climate change
predict the response of the global average temperature when large volcanic eruptions occur
explain the enhanced greenhouse effect
discuss how recent observations of change measured within regional ecosystems are related to global climate change
In the past, Earth has been significantly warmer (and mostly ice free) and significantly colder (especially during the so-called “Snowball Earth” eras) than it is today.
Climate change occurs when there are changes in insolation, albedo, and composition of the atmosphere.
Climate is the average of weather, and changes to the earth’s climate occur on long time scales.
Recent climate change, which has occurred during the modern instrument era, is the focus of this module. It is through the lens of long-term climate change (occurring on thousands to millions of years) that we will view earth’s current climate and recent climate change. The goal is to investigate how the principles listed above are shaping current climate events.

Figure
Northern Hemisphere Surface Air clearly shows that the current global average temperature reflects an interglacial warm period. If we focus in on the end of this record we can observe some of the fine scale changes in the global temperature records. Figure
Northern Hemisphere Surface Air combines proxy data (i.e., information from ice cores and tree rings) with the modern instrument record to create a graph showing the last 1300 years of Northern Hemisphere (hereafter, NH) temperatures. Each line on the top two panels represents a different temperature data set collected in the NH and the bottom panel color codes the percentage of overlap among these data sets.
The lymphatic system plays several crucial roles in the human body, functioning as a key component of the immune system and contributing to the maintenance of fluid balance. Its main functions include:
1. Immune Response: The lymphatic system produces and transports lymphocytes, which are a type of
asegid
to transport fluids fats proteins and lymphocytes to the blood stream as lymph
Anatomy is the study of the structure of the body, while physiology is the study of the function of the body. Anatomy looks at the body's organs and systems, while physiology looks at how those organs and systems work together to keep the body functioning.
Enzymes are proteins that help speed up chemical reactions in our bodies. Enzymes are essential for digestion, liver function and much more. Too much or too little of a certain enzyme can cause health problems

how does the stomach protect itself from the damaging effects of HCl
the normal temperature is 37°c or 98.6 °Fahrenheit is important for maintaining the homeostasis in the body
the body regular this temperature through the process called thermoregulation which involves brain skin muscle and other organ working together to maintain stable internal temperature
