Hurricanes, climate change and global warming

Anonyme, Mercredi, Novembre 23, 2005 - 16:36

21 November 2005. A World to Win News Service. While the US government has insisted that global warming doesn’t exist, most scientists are convinced otherwise. Some researchers say global warming was a major factor in the deadly series of hurricanes (as the violent tropical storms or cyclones that hit the Americas are called) that struck the Caribbean, Central America and the US recently. What is the link between global warming and tropical storms? What are the causes of global warming? To what extent is global warming caused by human activity, and what can be done about it? The following two-part article examines these questions.

21 November 2005. A World to Win News Service. While the US government has insisted that global warming doesn’t exist, most scientists are convinced otherwise. Some researchers say global warming was a major factor in the deadly series of hurricanes (as the violent tropical storms or cyclones that hit the Americas are called) that struck the Caribbean, Central America and the US recently. What is the link between global warming and tropical storms? What are the causes of global warming? To what extent is global warming caused by human activity, and what can be done about it? The following two-part article examines these questions.

The international science journal Nature reported that possible links between hurricane formation and global warming are a contentious issue in climate policy. The depth of the divide between supporters and sceptics was already apparent in January, when US meteorologist Chris Landsea resigned from the Intergovernmental Panel on Climate Change (IPCC) – an organisation working with the United Nations Environmental Programme. Landsea was protesting against statements made by his panel colleague, Kevin Trenberth, who had argued for a link between global warming and storms in a press conference.

Nature wrote, “Trenberth’s view is supported by the most recent and solid analysis of hurricane destructiveness over the past 30 years, by leading US hurricane researcher Kerry Emanuel of the Massachusetts Institute of Technology in Cambridge, Massachusetts.

Ceci est un média alternatif de publication ouverte. Le collectif CMAQ, qui gère la validation des contributions sur le Indymedia-Québec, n'endosse aucunement les propos et ne juge pas de la véracité des informations. Ce sont les commentaires des Internautes, comme vous, qui servent à évaluer la qualité de l'information. Nous avons néanmoins une Politique éditoriale , qui essentiellement demande que les contributions portent sur une question d'émancipation et ne proviennent pas de médias commerciaux.

This is an alternative media using open publishing. The CMAQ collective, who validates the posts submitted on the Indymedia-Quebec, does not endorse in any way the opinions and statements and does not judge if the information is correct or true. The quality of the information is evaluated by the comments from Internet surfers, like yourself. We nonetheless have an Editorial Policy , which essentially requires that posts be related to questions of emancipation and does not come from a commercial media.
