Sea ice extent 1970-2017

Description

The sea ice extent from 1978 to 2017 shows the average daily extent of sea ice in the northern hemisphere, measured in millions of square kilometers The sea ice extent is a measure of the surface area of the ocean covered by sea ice. This data is crucial for understanding changes in the Earth’s climate, as sea ice plays a significant role in regulating the planet’s temperature. The chart is likely to show fluctuations in the sea ice extent over the years, reflecting seasonal variations as well as long-term trends due to climate change.

Purposes:

1. Indicator of Climate Change:

Sea ice concentration is both an indicator and driver of high-latitude climate change with strong societal and ecological importance.

2. Modeling and Forecasting:

It is a key boundary condition for atmospheric models (including those used in atmospheric reanalyses) and a benchmark for coupled climate models.

3. Interactive Data Visualization:

This chart can provide an interactive visualization of the sea ice extent data. This allows users to explore the data in a more engaging and intuitive way. For example, the length and color of each bar in the chart can vary dynamically with the data, and additional information can be displayed when the mouse moves over the data

4. Historical Comparison:

The graph can provide information about the current state of the sea ice cover and how the most current daily data available compare with the record lows and record highs for the same date during the satellite era.

5. Educational Tool:

The graph can serve as an educational tool to increase public awareness about the impacts of climate change on sea ice extent
