This is the visual picture of Australia. Noted the building heat over Sumatra. The Antarctic Vortex is noted at the lower globe. The thing to remember is that clouds that don't carry heat to the poles act to dissipate the heat while providing 'shade' to Earth and reflecting the solar radiation out to space again before it enters the troposphere to increase the 'heat index' under the Greenhouse Gases. Clouds can be but aren't always beneficial. This is still an improved picture. No guarantees it will stay that way but it is hopeful. The heat over Sumatra is known to be a worrisome event.
