And what does this 350 number even mean?

350 is the number that leading scientists say is the safe upper limit for carbon dioxide—measured in "Parts Per Million" in our atmosphere. 350 PPM—it’s the number humanity needs to get back to as soon as possible to avoid runaway climate change.   read more about climate change

The science is clear: global warming is happening faster than ever and humans are responsible. Global warming is caused by releasing what are called greenhouse gases into the atmosphere. The most common greenhouse gas is carbon dioxide. Many of the activities we do every day like turn the lights on, cook food, or heat or cool our homes rely on energy sources like coal and oil that emit carbon dioxide and other heat-trapping gases. This is a major problem because global warming destabilizes the delicate balance that makes life on this planet possible. Just a few degrees in temperature can completely change the world as we know it, and threaten the lives of millions of people around the world. But don’t give up hope! You can help stop global warming by taking action here at 350.org.

We need an international agreement to reduce carbon emissions fast, and 2009 might be our best shot.

The United Nations is working on a global climate treaty, which is supposed to be completed in December of 2009 at a conference in Copenhagen, Denmark. But the current plans for the treaty are much too weak to get us back to safety. This treaty needs to put a high enough price on carbon that we stop using so much. It also needs to ensure poor countries a fair chance to develop.

This year, we can create a grassroots movement connected by the web and active all over the world.

We can hold our decision-makers accountable to producing a treaty that is strong, equitable, and grounded in the latest science. On 24 October, we’re holding a Global Day of Climate Action to do just this.

If this global movement succeeds, we can get the world on track to get back to 350 and back to climate safety. It won’t be easy, that’s why we need all the help we can get.

Proyecto Argo

September 27, 2008

 

600px-Argo_LogoArgo es un sistema de observación de los océanos de la Tierra que proporciona datos en tiempo real para su uso en el clima, las condiciones meteorológicas, oceanográficas y de investigación pesquera. El Argo consiste en una colección grande de sondas robóticas oceánicas pequeñas, que van a la deriva desplegadas por todo el mundo.  Las sondas miden la temperatura y la salinidad de los océanos a profundidades a 2 km. Una vez cada 10 días, las sondas emergen a la  superficie para transmitir las mediciones a los científicos en tierra vía satélite. Los datos recogidos son de libre acceso a todo el mundo, sin restricciones. El objetivo inicial del proyecto de desplegar 3000l sondas , concluyó en noviembre de 2007. El programa Argo es una colaboración de investigación entre  50 investigadores y los organismos operacionales de 26 países,  los Estados Unidos contribuyeron con  más de la mitad del total de la financiación (a partir de diciembre de 2004). Argo es un componente del Sistema Integrado de Sistema de Observación de los Océanos.

Actualmente el proyecto cuenta con 3148(agosto 2008) sondas distribidas en todos los mares y oceanos alrededor del mundo.
