Future Migrations as Earth Warms ( Animated Map, part 1)

cover


Ecosystems, where will 
animals move to survive? As climate change alters habitats and disrupts and will human development prevent them from getting there. The natural world is under siege by climate change.

Rising temperatures are pushing plants and animals outside their current range. To keep pace with climate change species will need a path to follow northward or up in elevation, minimally interrupted by human development. Warming temperatures, changing precipitation patterns, and extreme weather and climate events are likely to increase at a rate and magnitude not seen in more than 65 million years, according to a new study published in the journal Science.

The melting glacier problem.

A BNA blog posted in December discussed a report released by the United Nations Environmental Program (UNEP) urging countries to increase efforts to combat climate change and cited the rate at which glaciers are melting as the most critical piece of evidence so far to back up its position. UNEP, according to the blog post, said that the different rates of glacial melting, and the fact that some areas are experiencing small expansion of glaciers, underscores the multiple factors at work in determining the rate at which glaciers melt...

Droughts and Climate Change.

Until recently, many scientists spoke of climate change mainly as a “threat,” sometime in the future. But it is increasingly clear that we already live in the era of human-induced climate change, with a growing frequency of weather and climate extremes like heat waves, droughts, floods and fires. Today we will try to explain what’s going on with the fact that we experience very little or no rain at all; in certain places in the world such as Russia, the USA, Europe some part of Africa and in Asia. Future precipitation trends, based on climate model projections for the coming fifth assessment from the Intergovernmental Panel on Climate Change, indicate that droughts of this length and severity will be commonplace through the end of the century unless human-induced carbon emissions are significantly reduced.

Lack of Fresh Water and Impact on Human Activity… Global Warming, Droughts, Flods…

Climate change is about water climate adaptation and is about managing water more effectively. Founded in September 2010, the Alliance for Global Water Adaptation is a group of regional and global development banks, aid agencies and governments, and a diverse set of non-governmental organizations (NGOs) focused on how to manage water resources in way that is sustainable even as climate change alters the global hydrological cycle. We believe that water is a crosscutting theme that provides coherence to climate change adaptation and mitigation, integrating energy, water... Read more [...]

Humans change the world! What drought are you talking about?

Humans change the world! What drought are you talking about? A drought is a period of unusually persistent dry weather that persists long enough to cause serious problems such as crop damage and or water supply shortages. The severity depends upon the degree of moisture deficiency, the duration, and the size of the affected area. The major effects of climate change on water systems take place through changes in the hydrological cycle, basically the balance between temperature, and rainfall. Whilst some regions may have higher rainfalls this can evaporate through sustained increases in temperature... Read more [...]

Humans Change the World! Where do we stand with fresh water? Will there be enough for a more crowded world?

Sandra Postel, founder of the Global Water Policy Project, is recognized as one of the world's most respected authorities on fresh water issues and is hailed for her "inspiring, innovative, and practical approach" to promoting the preservation and sustainable use of Earth’s freshwater. For more than 25 years, Postel has lectured, taught, and written prolifically on the geography of water stress and the implications for food and agriculture... Read more [...]

Humans Change the World ! “Climate Change” What does it mean to me? What is it caused by?

The Industrial Revolution brought us Climate Change. After the Industrial Revolution we became a society of “instant gratification”. The industrial revolution made our life very easy and at the same time is destroying our planet. From the mining for commodities like: minerals, metals and rocks, let's not forget all the underground nuclear explosions and the pumping of oil, our planet is looking more and more like “Swiss Cheese” and now it is letting us know through: earthquakes, volcanoes and the increase of Co2. The time to change is here and now! The Industrial Revolution was a process of change from an agrarian, handicraft economy to one dominated by industry and machine manufacturing. It began in England in the 18th century... Read more [...]

So what is Climate Change?

So what is Climate Change? Do you think the world's climate scientist are lying about the data? What is more powerful than the sun, volcanoes, and all other things in nature and we are officially to "blame" for the world's climate change. Question - which change is it?
You may recall that in the 1970s that science was suggesting we prepare for another ice age.
So should I pack a swim suit or a parka? Point is, climate change is not that simple. The fact is that the Earth is getting warmer. There's a lot of information floating around about climate change. Most people know it has something to do with the "Industrial Revolution". Pollution, changing weather and car exhaust, climate change occurs when long-term weather patterns are altered for example, through human activity. Global warming is one measure of climate change, and is a rise in the average global temperature. We can decide to do nothing about this issue now, but we'll just pay for it later. Food prices will continue to rise and water will continue to become increasingly scarce leading to even more... Read more [...]
