This NOAA visualization on YouTube shows the seasonal variations in sea surface temperatures and ice cover from 1985 to 2007. The visualization is based on data collected by NOAA polar-orbiting satellites. El NiÃo and La NiÃa are easily identified, as are the trends in decreasing polar sea ice.

A short video that discusses how changing climate is affecting the population of AdÃlie penguins.

This activity from NOAA Ocean Service is about using aerial photographs to assess the impact of extreme weather events such as Hurricane Katrina. The activity features aerial views of Biloxi, MS post-Katrina and enables students to see evidence of the power of extreme weather on the environment.

These graphs show carbon dioxide measurements at the Mauna Loa Observatory, Hawaii. The graphs display recent measurements as well as historical long term measurements. The related website summarizes in graphs the recent monthly CO2, the full CO2 Record, the annual Mean CO2 Growth Rate, and gives links to detailed CO2 data for this location, which is one of the most important CO2 tracking sites in the world.

In this video, NOAA's Deke Arndt, Chief of the Climate Monitoring Branch at the National Climatic Data Center, recaps the temperature and precipitation data for the continental US in summer 2012. It describes how these conditions have led to drought and reduced crop yields.

This learning activity explores the concept of resiliency. It allows students to make city planning decisions and then employs a game to test their resilience decisions against potential impacts from severe weather, climate change, and natural hazards.

This set of interactive data visualizations show the weather and climate events that have had the greatest economic impact on the US from 1980 to 2016.

This video describes what black carbon is, where is comes from, and how it contributes to sea ice melt and global warming.

In this activity, groups of learners work together to create edible models of chemicals involved in autotrophic nutrition. Learners use candy to represent elements involved in the chemical equations for chemosynthesis and photosynthesis. Learners complete a Lab Report based on their findings and understanding of chemosynthesis and photosynthesis. This detailed lesson guide includes background information, additional information for teachers of deaf students, and extensions.

This activity from NOAA Earth System Research Laboratory introduces students to the scientific understanding of the greenhouse effect and the carbon cycle. The activity leads them through several interactive tasks to investigate recent trends in atmospheric carbon dioxide. Students analyze scientific data and use scientific reasoning to determine the causes responsible for these recent trends. By studying carbon cycle science in a visual and interactive manner, students can learn firsthand about the reasons behind our changing climate.

In this activity, learners take on the role of a carbon atom and record which reservoirs in the carbon cycle they visit. Learners will compare and contrast their trip with those of other learners to discover information about sources and sinks, and residence times of the different reservoirs. Ocean processes are highlighted to allow the educator to define the biological pump and explain its importance to climate. Helping learners understand the carbon cycle is essential to their understanding of the causes and consequences of climate change.

In this activity (on page 1), learners role play as atoms to explore how atoms can be rearranged to make different materials. Learners group together and link arms or hold hands to form chemical bonds and act out the processes of photosynthesis and respiration. Use this activity to introduce the carbon cycle and follow this activity with two associated activities from the same resource.

In this activity (on page 7), learners explore the meaning of a "carbon sink." Using simple props, learners and/or an educator demonstrate how plants act as carbon sinks and how greenhouse gases cause global warming. This activity is the second in a series of three activities that introduce learners to the carbon cycle (see related sources), although it is not mandatory that all three activities are completed as a set.

In this activity, learners explore the human influences on the carbon cycle and examine how fossil fuels release carbon. Learners role play as miners, power plant operators, car drivers, and home owners in a city. Learners will act out how each member of society contributes to the carbon cycle and then create a classroom mural depicting the path of carbon. Learners can reflect on this process as well as brainstorm ways to lower their carbon footprints. This activity is the third in a series of three activities that introduce learners to the carbon cycle (see related sources), although it is not mandatory that all three activities are completed as a set.

This is a rich compilation of resources and tools to help decision-makers across the US identify their local climate threats and vulnerabilities and reduce their risks from impacts of climate​ variability and change. As part of President Obama's Climate Action Plan, the toolkit was developed by NOAA in partnership with NASA and other departments and agencies in the U.S. Global Change Research Program.

This teaching activity addresses environmental stresses on corals. Students assess coral bleaching using water temperature data from the NOAA National Data Buoy Center. Students learn about the habitat of corals, the stresses on coral populations, and the impact of increased sea surface temperatures on coral reefs. In a discussion section, the connection between coral bleaching and global warming is drawn.

Coral Reefs in Hot Water is a short video displaying computerized data collected on the number of reefs impacted by coral bleaching around the world.

This activity models the mass coral spawning event that takes place at Flower Garden Banks National Marine Sanctuary every August. The result is like a snow globe in which the думsnowдуќ floats up instead of down, and the scene is a model of a coral reef, complete with Christmas tree worms.

This tool provides a summary of daily records broken in several weather parameters (temperature, precipitation, snow fall, snow depth), over various time intervals, in the US and globally.
