The satellite imagery of the flooding in Pakistan is insufficient to grasp how widespread the devastation is, unless you zoom out enough (which you can do at the MODIS page). The imagery focuses on the flood plain of the Indus River: it covers most of Sindh province and a good chunk of Baluchistan. See The Washington Post’s maps for perspective. The Earth Observatory and MODIS pages, as well as the CNN article, have before/after image sliders: Earth Observatory compares the situation to three weeks ago, the other two to last year.

Update, 1 Sept:

The ESA has released the above image based on Copernicus Sentinel-1 data. More than a third of Pakistan is now under water.

Update, 3 Sept: The Guardian has more before/after imagery.

The deep freeze is unevenly distributed. NASA Earth Observatory published this temperature anomaly map based on data from the MODIS instrument on NASA’s Terra satellite. A temperature anomaly map shows how much warmer or colder temperatures are versus the average—in this case, land surface temperatures from 26 December 2017 to 2 January 2018 are compared to the 2001-2010 average for the same period. While it’s awfully cold in Canada, and the central and eastern United States, it’s warmer than normal in the southwest. And if you look beyond the North American continent (which is something people should do more often), it’s generally warmer worldwide, particularly in Europe and Asia:

NASA Earth Observatory: “Clouds may seem like distant, ephemeral features that have little to do with life on Earth. In fact, they affect everything from the viability of ecosystems, to how much carbon plants absorb, to the reproductive success of reptiles. So by mapping clouds, new research shows, scientists can indirectly map life.”
