It is we humans who are fragile and vulnerable and the earth that is hearty and powerful, and holds us in its hands. In pragmatic terms, our challenge is less to save the earth from ourselves and more to save ourselves from an earth that, if pushed too far, has ample power to rock, burn, and shake us off completely.

Less than animal agriculture. So most people think that buying a prius is the answer, and it's certainly not wrong, but it's not the biggest agent of climate change. James cameron, "Director James Cameron on Vegan diet Ecorazzi, april 12, 2014 2 likes, the violence present in our hearts, wounded by sin, is also reflected in the symptoms of sickness evident in the soil, in the water, in the air and in all forms.

But linke the roads in Robert Frost's familiar poem, they are not equally fair. The road we have long been traveling is deceptively easy, a smooth superhighway on which we progress with great speed, but at its end upbringing lies disaster. The other fork of the road-the one less traveled by-offers our last, our only chance to reach a destination that assures the preservation of the earth. Rachel carson, silent Spring 2 likes, when we marvel at that blue marble in all its delicacy and frailty, and resolve to save the planet, we cast ourselves in a very specific role. That role is of a parent, the parent of the earth. But the opposite is the case.

Thad allen, smithsonian Magazine, march 2010 3 likes, scientists. Out on a limb in the face of a peer group which holds a robust counter-view, have ultimately been proven correct on many occasions during the history of science. One can resume think of Galileo, and even Einstein. But the stakes are a little different with global warming. The future of civilization, perhaps even of life on Earth, did not potentially hinge on Galileo or Einstein being right. Leggett, the carbon War 2 likes, this may surprise you, because it surprised me when I found out, but the single biggest thing that an individual can do to combat climate change is to stop eating animals. Because of the huge, huge carbon footprint of animal agriculture. I was shocked to find out that animal agriculture directly or indirectly accounts for.5 of all greenhouse gas emissions, compared to all transportation - every ship, car, truck, plane on the planet only accounts for.

Al gore, speech at National sierra Club Convention, sept. 9, 2005 3 likes. All across the world, in every kind of environment and region known to man, increasingly dangerous weather patterns and devastating storms are abruptly putting an end to the long-running debate over whether or not climate change is real. Not only is it real, it's here, and its effects are giving rise to a proposal frighteningly new global phenomenon: the man-made natural disaster. Barack obama, speech, Apr. 3, 2006 3 likes, i'm agnostic as to the causes. All i know is there is water where there once was ice.

"We can slow global warming, keep temperature increases to the lower end of the scale and reduce the severity of future droughts. The kyoto Protocol is the first international agreement with targets for reducing greenhouse gas emissions and slowing global warming it is in our national interest to ratify the treaty she said. For further information: Martin Hiller, wwf climate Change Programme's Communications Manager, tel.:, mobile. Quot;tions about global warming, people tend to focus on the here and now. The problem is that, once global warming is something that most people can feel in the course of their daily lives, it will be too late to prevent much larger, potentially catastrophic changes. Elizabeth kolbert, the new Yorker, apr. 25, 2005 3 likes, two thousand scientists, in a hundred countries, engaged in the most elaborate, well organized scientific collaboration in the history of humankind, have produced long-since a consensus that we will face a string of terrible catastrophes unless we act to prepare ourselves.

The report, Global Warming Contributes to australias Worst Drought, compares the 2002 drought with the four other major droughts in the country since 1950 and has found higher temperatures caused a marked increase in evaporation rates from soil, watercourses and vegetation. The report warns that higher temperatures and drier conditions have created greater bushfire danger than previous droughts. Drought severity also has increased in the murray darling Basin, which produces 40 percent of Australias agricultural e report states that in 2002 Australia recorded its highest-ever average march-november daytime maximum temperature, with the temperature across Australia.6C higher than the long term average and. The murray darling Basin experienced average maximum temperatures more than.2C higher than in any previous drought since 1950. "The higher temperatures experienced throughout Australia last year are part of a national warming trend over the past 50 years which cannot be explained by natural climate variability alone said Professor david Karoly, formerly Professor of Meteorology at Monash University, who co-authored the report with.

"Most of this warming is likely due to the increase in greenhouse gases in the atmosphere from human acitivity such as burning fossil fuels for electricity and transport and from landclearing.". According to Professor Karoly, the actual trend in Australian temperature since 1950 is now matching the climate model studies of how temperatures respond to increased greenhouse gases in the atmosphere. He believes that this is the first drought in Australia where the impact of human-induced global warming can be clearly observed. Dr James Risbey said that although the 2002 drought was related to natural climate variations associated mughal with El niño, the higher temperatures could not be attributed solely to this factor: "While higher temperatures are expected during El niño triggered droughts, the 2002 drought temperatures are. "The report contains new data on evaporation rates and says low rainfall and higher evaporation has adversely impacted on agricultural productivity with lower crop production leading to lower export earnings for farmers. According to Anna reynold, global warming is a reality want that is affecting the livelihoods of rural Australians. Wwf is urging Prime minister Howard to act to prevent further economic and environmental devastation.

Vegetation changes play a significant role in the rainfall variability. The increase in rainfall has allowed more plants to grow, which in turn increases precipitation even more. Plants transfer moisture from the soil into the air by evaporation from their leaves and hold water in the soil close to the surface, where it can also evaporate. The darker surface of plants compared with sand also absorb more solar radiation, which can create convection and turbulence in the atmosphere which might create rainfall. Vegetation effects account for around 30 percent of annual rainfall variation in the sahel. The increased vegetation will fix the soil, enhance its anti-wind erosion ability, reduce the possibility of released dust and consequently cause a decline in the numbers of sand-dust storms.


However, the greening cannot be explained solely by the increase in rainfall. There were vegetation increases in areas where rainfall was decreasing, suggesting another factor was responsible for the greening in these areas. This other factor might have been the rise of atmospheric CO2 levels. The aerial fertilization effect of the ongoing rise in the airs CO2 concentration increases greatly the productivity of plants. The more co2 there is in the air, the better plants grow. Rising atmospheric CO2 levels also have an antitranspiration effect, which enhances the water-use efficiency of plants and enables them to grow in areas that were once too dry for them. Posted on, sydney, australia: A new scientific report released today by wwf and leading meteorologists shows that human-induced global warming was a key factor in the severity of the 2002 drought in Australia.

There are now more trees, more grassland for livestock and a 70 increase in plan yields of local cereals such sorghum and millet in recent years. Vegetation has also increased significantly in the past 15 years in southern mauritania, north-western Niger, central Chad, much of Sudan and parts of Eritrea. In Burkina faso and Mali, production of millet rose by 55 percent and 35 percent, respectively, since 1980.6 Satellite photos, taken between 19, revealed the extensive re-greening throughout the sahel. Aerial photographs and interviews with local people have confirmed the increase in vegetation. Causes of the greening, the main reason for the greening of the sahara and the sahel has been an increase in rainfall since the mid-1980s. Of the 40 rainfall stations across the sahel, most of them have been observing an increase in rainfall. If sustained, the increasing rainfalls could revitalize drought-ravaged regions, reclaiming them for farming. The United Nations Africa report of 2008 confirmed that the greening of the sahel is now well established and that increases in rainfall are the main driver of the change in the vegetation cover. The report noted that there was a 50 increase in vegetation in parts of Mali, mauritania and Chad during.

Global warming was infant supposed to increase the frequency and severity of the droughts, which would make crop-growing unviable and cause even worse famines. . According to the United Nations, the outlook for the people in the sahel was bleak. However in sharp contrast to this gloomy outlook, it seems that global warming has exactly the opposite effect on the sahara and the sahel. The sahara is actually shrinking, with vegetation arising on land where there was nothing but sand and rocks before. The southern border of the sahara has been retreating since the early 1980s, making farming viable again in what were some of the most arid parts of Africa. There has been a spectacular regeneration of vegetation in northern Burkina faso, which was devastated by drought and advancing deserts 20 years ago. It is now growing so much greener that families who fled to wetter coastal regions are starting to come back.

compensate poor ones for the damage done by emissions. He said: One should continue to remain sceptical of overconfident claims that climate change, by which is meant fossil fuel emissions, always causes negative effects in these African drylands. Full story, philipp mueller: The sahel Is Greening. Global Warming Policy foundation, Global warming has both positive and negative impacts. However, very often only the negative consequences are reported and the positive ones omitted. This paper will show an example of a positive effect of warming. The people living in the sahel, a semiarid area just south of the sahara desert, spanning the entire African continent from the Atlantic Ocean to the red sea, were suffering from several devastating droughts and famines between the late 1960s and the early 1990s. The draughts were triggered by decreases in rainfall from the early 1950s to the mid-1980s.

Professor Sutton said: This might not sound like a big number but in fact its a substantial shift in the context of this region and the very severe drought experienced in the 1970s and 1980s. The scientists, using a supercomputer climate simulator, said that heat-trapping emissions accounted for three quarters of the recovery in rainfall, rather than other suggested factors such as changes in sea temperature. Warming by greenhouse gases means that air can hold more moisture, bringing more rains, with and can shift winds, influencing the monsoon. Professor Sutton cautioned that the change in rainfall was only local and that many parts of Africa faced problems from global warming, including heatwaves, desertification, floods, rising sea levels and an increase in malaria. It would be naive to conclude that this is a good thing for Africa, he said. In future, there are other effects — the rise in temperatures can be detrimental to crops. He said that other impacts of climate change, such as changes in the temperatures of the Atlantic and Indian oceans, could cause drought to return to the sahel. The Stockholm Resilience centre said the greening of the sahel was also the result of changes in farming practice.

Climate change has achieved what Bob Geldof and live aid failed to do by ending the writing drought in the sahel region of Africa that killed more than 100,000 people in the 1980s, a study has found. Rising greenhouse gases caused rains to return to the region south of the sahara, from Senegal to sudan, boosting crop yields since the 1990s and helping the population to feed itself without relying on foreign donations. The rare positive effect of climate change is identified in a study which concludes that the continued rise in emissions is favourable for sustaining, and potentially amplifying, the recovery of Sahel rainfall. A weather chart showing how average rainfall in the sahel was very low in the 1980s but is now increasing again. The natural variability of Sahel rainfall. Rowan Sutton, a professor at the national centre for atmospheric science at the University of reading and co- author of the study, said: Amounts of rainfall have recovered substantially. It was a surprise that the increase in greenhouse gases appears to have been the dominant factor. The study, in the journal, nature Climate Change, found that Sahel summer rainfall was about 10 per cent,.3mm, higher per day in than in the drought period of 1964-93.
