Effects of Climate Change

Creation Process:

• The map was created using climate data from various sources, including NOAA and Esri, within ArcGIS Pro. Each panel (oxygen change, pH change, and temperature change) represents data visualized through global climate models that predict how different aspects of the ocean will shift in response to ongoing climate change.

• Specific raster layers were applied to each variable, using a diverging color ramp to visualize increases or decreases relative to baseline levels. Data was projected using the WGS 1984 coordinate system.

Visual Details:

• The left panel displays oxygen change, with blue representing oxygen increase and red indicating oxygen loss. Significant oxygen depletion is seen in the Southern Ocean.

• The right panel shows pH change, with color gradients indicating increased acidity (in red) in the Southern Hemisphere's waters.

• The lower panel visualizes temperature change, with red denoting warming waters and blue representing cooling trends. The map focuses on dramatic temperature increases near the poles.

• The map includes a clear analysis box summarizing the effects of these changes on marine ecosystems, alongside a legend and scale bar for accurate interpretation. This map effectively communicates the global impact of climate change on the ocean’s health.
