A paper published by researchers from Chinese universities suggests that global warming is causing changes in the length and onset of the four seasons. Summers are becoming longer and hotter, while winters are becoming shorter and warmer. This trend is expected to continue and may be amplified in the future. The shift in seasonal patterns could have negative impacts on ecosystems, agriculture, and the occurrence of extreme weather events. It is important for humanity to take responsibility and mitigate the effects of climate change to ensure a more stable future. [Extracted from the article]

The author reflects on a paper speculating on runaway climate change if the Earth warms by just two degrees Celsius and on broad reactions to the paper. He states that the Earth will likely warm by three or four degrees Celsius unless drastic environmental policy changes are enacted worldwide which would have significant impacts on lifestyles. He suggests that humanity can still prepare and adapt for the future impacts of climate change.

The article focuses on global warming. Satellite images of the Arctic region released in late September by the scientists show more water, less ice. As climate change pushes polar temperatures higher, each summer's melt takes a bigger toll. Hurricane Katrina was not an isolated natural disaster but an obvious sign of a future far less predictable than the past. Massachusetts Institute of Technology hurricane specialist Kerry Emmanuel published a landmark paper in the British science magazine "Nature," shows that in the past half century tropical storms have been lasting 60 percent longer and spinning winds 50 percent more powerful. More than a decade ago, environmental researcher Norman Myers began adding up the number of humans at risk of losing their homes to global warming. The bulk of those refugees will be in countries where nobody emits much carbon. Meanwhile, the 4 percent of the world's population living in the United States produces 25 percent of the planet's carbon dioxide.

This article discusses the Kyoto Protocol on climate change and how since its ratification in Canada few changes have been made to battle global warming. The day after Canada officially ratified the Kyoto Protocol on climate change in December 2002, David Anderson was in New York City to deposit the freshly signed paper with the Treaty Section of the United Nations. It was his shining moment as federal environment minister: an avowed multilateralist and an unabashed tree hugger, Anderson had spent three years battling opponents -- and sometimes cabinet colleagues -- over a deal he firmly held to be a turning point in the war against global warming. Whatever it was about the Kyoto accord that stirred such emotions two years ago seems like a distant memory, to the point where neither proponents nor critics of the deal give it much chance of making a difference in Canada. Since the conception of the protocol in 1990, greenhouse gas emissions in Canada have climbed some 20 per cent (as of 2002), and all signs suggest those numbers have increased since Anderson's giddy time in New York two years ago. But most critics agree on the basic errors that have led us to our current dilemma, where reaching our stated goal of cutting emissions six per cent below 1990 levels by 2010 -- a reduction of at least 240 megatonnes per year -- would require a brand of resolve we simply don't have. Our most grave, and perhaps most foreseeable, mistake was fooling ourselves into thinking we could do our part under Kyoto without inflicting pain on so-called large final emitters.

Presents an essay on climate change and global warming. Rise of carbon dioxide levels; Paper published by the United Kingdom Meteorological Office's Hadley Center in "Nature" regarding the results of a computer simulation of the future global carbon cycle; Impact of methane hydrate failure on the global environment; Reference to the motion picture "The Day After Tomorrow"; Need for global warming to be addressed in the political arena; Military implications of climate change.

The article discusses the "China's Policies and Actions for Addressing Climate Change" white paper released by China. The white paper on global warming admits that China is one of the countries that easily feel the impact of climate change. The paper also outlines strategies to be implemented by the country which include international cooperation and innovation of science and technology.

The article presents information on the review of various scientific writings on climate change, that have been published on internet between 1991 and 2012, by U.S. scientist James Lawrence Powell. Powell came across around 13950 articles, out of which 24 papers clearly reject the theory of global warming.

Provides evidence that global warming is caused by man's influence on nature. Reference to a paper by Tim Barnett of the Scripps Institution of Oceanography in La Jolla, California, regarding the impact of human activity on global warming; Report that Barnett focused his climate change research on changes in ocean temperatures.

The article maintains that the effects of global warming have become visible in the form of climate change. A paper published in the periodical "Geophysical Research Letters" showed evidence that runaway feedback on climate change has began. It is reported that in 2007 methane levels rose again in the atmosphere. Also it is stated that global meltdown has started. Further some steps are suggested for its prevention which includes reducing carbon pollution and stopping opencast coal mining.

In this article the author reviews the performance of various British newspapers on the subject of climate change and global warming. The piece was written in light of record high summer temperatures in the U.K. in 2006. The conservative papers, the "Times," "Sun" and "Evening Standard" featured writers unconvinced by the idea of global warming. He also comments favorably on "The Guardian" newspaper's new "G2" supplement.

The article focuses on the study conducted by researchers at the University of California, Northern Arizona University, and in the Netherlands regarding plants' ability to remove carbon dioxide from the atmosphere and store it as carbon in the soil. The findings challenge assessments and model projections from the Intergovernmental Panel on Climate Change that have anticipated increases in soil carbon with rising carbon dioxide. One of the researcher Johan Six said that future carbon storage by land ecosystems may be smaller than previously thought. Many plants can move nitrogen from the air into soils, and some researchers expected rising atmospheric carbon dioxide levels to speed up this natural nitrogen pump. But the studies analyzed in this paper revealed that this process, called nitrogen fixation, cannot keep up with increasing carbon dioxide unless other essential nutrients, such as potassium, phosphorus, and molybdenum, are added as fertilizers. The researchers acknowledge that plants do play a role in mitigating global warming, with about half of the carbon dioxide emitted into the atmosphere stored, at least temporarily, by ecosystems.

Focuses on the approaches that can be taken to address the issue of climate change. Effects of global warming; Influence of human activities on the occurrence of global warming according to a study that reviewed scientific papers on global warming between 1993 and 2003.

This article, the third of a series on the Copenhagen Consensus project, examines climate change. Global warming looms, in many people's minds, as one of the biggest threats facing the planet. Over the past 20 years researchers have gathered evidence that the burning of fossil fuels is causing temperatures to rise. However, the exact pace of global warming, as well as the size of mankind's contribution to the warming trend, remain uncertain. Aside from these issues is the question of precisely how greenhouse-gas emissions should be abated, assuming that they need to be reduced at all. In a new paper for the Copenhagen Consensus project, William Cline of the Centre for Global Development and the Institute for International Economics examines these topics. Rising temperatures are capable of causing great economic harm--though a lot depends not just on how big future rises prove to be but also on how quickly they happen.
