Water in 2050

To be able to adequately feed and support the world’s growing population, our global economy needs to continue to grow. Water is critical to future growth. But it can also become the major limiting factor to growth. For instance, businesses in water-scarce areas are already at risk, and so investors are increasingly taking water supply into consideration during their decision-making processes. Given today’s approach to water management, there is only so much growth that can be sustained. Gains in efficiency and productivity in water management and utilization can reduce these risks and enable higher levels of sustainable growth, but how much higher? How far-reaching do those gains have to be? And can we make a difference in a timely enough manner by understanding that the path for sustainable growth requires more than green solutions – but also requires blue ones? The answers lie in examining current demand and supply pressures and looking at trends within each. Demand pressures include population growth and an increase in water-intensive diets as a portion of the population moves into increasingly higher water-consumption behaviors. Demand pressures also include growing urban, domestic and industrial water usage. Climate change plays a role by creating additional water demand for agriculture and for reservoir replenishment. On the supply side, issues such as water transport, availability and variability present challenges, as does the decline in renewable water resources.

In nearly every one of these categories, trends are moving in the exact opposite direction necessary to sustain future growth. Taken together, these trends create “water stress.” And the resulting ecosystem pressures along with economic and political conflict only exacerbate that stress.

Today, many regions of the world are already water stressed due to population and economic growth.

In fact, 2.5 billion people (36% of the world population) live in these regions and more than 20% of the global GDP is already produced in risky, water-scarce areas affecting production, as well as corporate reputations when competition over water usages develops. Given today’s accelerated pace of human development and the slow pace of managing issues as complex as water resources, tomorrow’s challenges are already at our door. Whether improving our governance models or our infrastructure systems, years and even decades (not weeks or months) are required to implement change! This is especially troubling when considering analysis by the International Food Policy Research Institute (IFPRI), which found that 4.8 billion people – more than half the world’s population – and approximately half of global grain production will be at risk due to water stress by 2050 if status quo, business-as-usual behavior is followed. The IFPRI study also found that 45% of total GDP ($63 trillion) will be at risk due to water stress by 2050. That’s 1.5 times the size of today’s entire global economy! By wasting less, polluting less, reusing more, managing effectively and becoming more efficient in all uses of water – individual, collective, agricultural and industrial – we can achieve higher water productivity levels (economic output per drop) and reduce water stress.

Continued evolution of technology and infrastructure improvements will enhance water supply capacity for cities and industries while helping deliver clean drinking water and sanitation services to rural populations and the urban poor. In so doing, more than 1 billion people and about $17 trillion in GDP will no longer be at risk of unsustainable water supplies by 2050.

Well it's official. Global record cold temperatures this year have been fantastic for The Great Lakes of North America. Another month of snow, ice, and freezing temperatures has led government experts to project water levels in the Great Lakes will rise even more in the coming months than earlier estimated. We will be back to historic averages.

On Wednesday, ice covered roughly 90 percentof the Great Lakes, according to the National Oceanic and Atmospheric Administration. It puts the Lakes within striking distance of the known record of 94.8 percent set in 1994. Six-month forecasts generated by the Army Corps raise the possibility that all but Lakes Michigan and Huron could rise above their long-term averages by this summer.

It's been a long, cold winter. The snow covered Pyramids--not the fake ones--looked astonishing this year. Snow on the pyramids has not happened in well over 100 years. And records have been set: The coldest temperature ever recorded on earth occurred in Antarctica this year at minus 135 degrees below Fahrenheit, trumping a record set in 1983. So cold, a NASA space suit would come in handy. The record was captured by NASA's Aqua MODIS Satellite.

Speaking of ice, a Russian expedition ship carrying a gaggle of Global Warming Scientists got stuck in the ice earlier this year. They were there to show how Global Warming had made the ice disappear, but, found themselves stuck in record-level Antarctic Ice.A Chinese Icebreaker Xue Long, or Snow Dragon, went to rescue the Global Warming Scientists, but the rescue Icebreaker also got stuck in the ice.
