Global warming is already underway with consequences that must be faced today as well as tomorrow. Evidence of changes to the Earth’s physical, chemical and biological processes is now evident on every continent.
To fully appreciate the urgency of climate change, it’s important to understand the ways it affects society and the natural environment. Sea levels are rising and glaciers are shrinking; record high temperatures and severe rainstorms and droughts are becoming increasingly common. Changes in temperatures and rainfall patterns alter plant and animal behaviour and have significant implications for humans. In this section, explore the connections between the climate data and the changes happening around you—and those you can expect to see in the future—in all parts of the globe, including your own backyard.
Not only are global warming-induced changes currently underway, but scientists also expect additional effects on human society and natural environments around the world. Some further warming is already unavoidable due to past heat-trapping emissions; unless we aggressively reduce today’s emissions, scientists project extra warming and thus additional impacts.
A warmer climate spurs the evaporation of water from land and sea and allows the atmosphere to hold more moisture—thus setting the stage for more extreme precipitation. The atmosphere’s water-holding capacity increases by about 4 percent for every 1° Fahrenheit (0.6° Celsius) rise in temperature. This effect is similar to the difference between a warm bathroom and a cold bathroom: the mirror fogs up more when the air is warmer.
While some regions are likely to get wetter as the world warms, other regions that are already on the dry side are likely to get drier.
Global warming affects evapotranspiration—the movement of water into the atmosphere from land and water surfaces and plants due to evaporation and transpiration
Humans use water for everything from drinking and bathing to growing crops, supporting livestock and fish farms, shipping goods, generating electricity, and simply relaxing and having fun. Yet climate change is producing profound changes in this precious commodity, threatening water availability, access, and even quality.
Loss of mountain snow-pack reduces the amount of water available for irrigation downstream, while earlier spring snow-melt affects the timing. Saltwater intrusion may contaminate the supply from groundwater.
Lower lake and river levels may threaten the capacity of hydroelectric plants, while higher temperatures may mean that water is too warm to cool coal and nuclear power plants, leading to power brownouts. Shrinking mountain glaciers threaten electricity generation as well.
Water Powered Technologies Ltd is the leading designer of zero energy water management systems. They are constantly expanding a range of solutions which do not use any fossil fuels or electric power. Our products are environmentally friendly which will reduce the impact on global warming. The Company uses zero energy rainwater harvesting to turn rainwater into safe, drinking water for remote communities as well as provide solutions for resource efficient agriculture where the Company’s patented PAPA Pumps are being used in Zimbabwe, Kenya, Angola and South Africa. Farmers and remote communities appreciate the light, easy to maintain PAPA Pumps which are able to transport water for free over long distances. Currently larger installations with multiple PAPA Pumps delivering over 1 million litres a day are being quoted for in Ghana Oil Palm plantations where the expected return on investment vs diesel pumps should be only a few years.
For mining and very large agricultural concerns, the Company launched the Venturo Pump in 2015; models of this unit can move over 1 billion litres a year and – as with the PAPA Pump it just uses the natural flowing water to power a pumping action which can send water to great distances.
