Ocean heat storage has increased substantially since 1993, hitting a record high in 2015, according to the State of the Climate in 2015 report. Ocean warming accounts for over 90% of the warming in Earth’s climate system.
We're nine laps into the race to set a new global annual temperature record. NOAA climate scientist Deke Arndt talks about how this year's race might end--and why yearly rankings tell us less about the big picture of climate change than we might think.
NOAA’s National Climatic Data Center announced that last month was the warmest September on record for the planet. If the surface temperature remains elevated at the same level for the remainder of the year, 2014 will set a new record for the warmest annual average temperature since records began in 1880.
This demonstration shows how water absorbs more heat than air. The corollary that is made is that the oceans are absorbing a lot of the heat related to climate change. The video tutorial shows an engaging demonstration that teachers can do live in their classrooms as part of a larger lesson/discussion about global warming. The video itself also includes an animation of how greenhouse gases contribute to global warming and concludes by mentioning simple solutions for students.
This activity allows students to demonstrate the thermal expansion of water for themselves using water bottles and straws. The discussion allows them to explore the connection between this concept and sea level rise due to climate change.
In this worksheet-based activity, students review global visualizations of incoming sunlight and surface temperature and discuss seasonal change. Students use the visualizations to support inquiry on the differences in seasonal change in the Northern and Southern Hemispheres and how land and water absorb and release heat differently. The activity culminates in an argument about why one hemisphere experiences warmer summers although it receives less total solar energy.
