More than nine million flood victims in Pakistan face an "unimaginable catastrophe" of disease and malnutrition due to a massive shortfall in emergency funding, aid agencies have warned.

This year's flooding came as millions were still trying to recover from a similar disaster last year, described by the UN as the worst in its history. Shaheen Chughtai, a humanitarian policy adviser at Oxfam, said: "Last year it was very clear that this was an extraordinary disaster. It was a once in a century flood. The fact we have had floods again this year in Pakistan means that in terms of media news agendas it looks like a continuation of a familiar story.

Continued flooding does threaten the plants, however. As nuclear engineer Arnie Gundersen explains in the above video, cooling pumps must operate continuously, even years after a plant is shut down. One group, the Foundation for Resilient Societies, has proposed solar panels and other high-reliability power sources to supply backup cooling for the fuel pools at nuclear plants.

While hindsight might be 20/20, the lack of foresight can be blindingly deadly when it comes to radioactive waste that lasts tens of thousands of years for the measly prize of 40 years of electricity.

“Ft. Calhoun is the designated spent fuel storage facility for the entire state of Nebraska…and maybe for more than one state. Calhoun stores its spent fuel in ground-level pools which are underwater anyway – but they are open at the top. When the Missouri river pours in there, it’s going to make Fukushima look like an x-ray.

Scientists predict this year's "dead zone" of low-oxygen water in the northern Gulf of Mexico will be the largest in history — about the size of Lake Erie — because of more runoff from the flooded Mississippi River valley.

Each year when the nutrient-rich freshwater from the Mississippi and Atchafalaya rivers pours into the Gulf, it spawns massive algae blooms. In turn, the algae consume the oxygen in the Gulf, creating the low oxygen conditions. Fish, shrimp and many other species must escape the dead zone or face dying

Federal and university scientists predict this year's zone will be between 8,500 square miles and about 9,400 square miles. The actual size of the dead zone will be measured over the summer.

With wildfires, floods, tornadoes, and other dramatic weather events making front page news around the world, many people are asking questions about the signs and impacts of a changing climate. Climate Science is the World Resources Institute’s periodic review of the state of play of the science of climate change. With summaries and explanations of recent peer-reviewed research from a host of scientific journals, Climate Science is a window into what scientists are discovering about how climate change affects the living things and complex systems of our planet.

The latest edition, Climate Science 2009-2010 will be released this summer. In the meantime, we have assembled a preview of some of the research covered in the report. Take a look at our slideshow detailing the huge variety of impacts we are already seeing from warming global temperatures, including insights into sea-level rise, human migration, weather extremes, and the shrinking habitats of wildlife. Then, use our interactive map to learn more about the regional consequences of climate change around the United States

The United States experienced some of the most extreme weather events in its history this spring, including deadly outbreaks of tornadoes, near-record flooding, drought and wildfires

Damages from these disasters have already passed $32 billion, and the hurricane season, which is just beginning, is projected to be above average, according to the National Oceanic and Atmospheric Administration.

Government scientists said Wednesday that the frequency of extreme weather has increased over the past two decades, in part as a result of global warming caused by the accumulation of carbon dioxide in the atmosphere
