 &lt;P align=left&gt;Dos centros que miden la concentraci&#243;n de di&#243;xido de carbono en la atm&#243;sfera

 &lt;P align=left&gt;alcanza ya las 391 partes por mill&#243;n (ppm) en el primer centro y hasta 397 ppm en

 &lt;P align=left&gt;el segundo, acerc&#225;ndonos m&#225;s al punto de no retorno de 450 ppm donde el

 &lt;P align=left&gt;calentamiento ser&#225; ya incontrolable, es decir, la concentraci&#243;n del gas invernadero

 &lt;P align=left&gt;seguir&#225; subiendo, aunque el hombre comience a reducir sus emisiones. Para

 &lt;P align=left&gt;entonces, la temperatura media del planeta habr&#225; subido 2 grados cent&#237;grados

desde la era preindustrial.

&lt;/FONT&gt;&lt;/FONT&gt; &lt;P align=left&gt;

 &lt;P align=left&gt;Hasta ahora, era conocido que el nivel de di&#243;xido de CO&lt;/FONT&gt;&lt;/FONT&gt;&lt;FONT face=Verdana size=1&gt;&lt;FONT face=Verdana size=1&gt;2 &lt;/FONT&gt;&lt;/FONT&gt;&lt;FONT face=Verdana size=2&gt;&lt;FONT face=Verdana size=2&gt;actual era el m&#225;s alto

 &lt;P align=left&gt;desde hacia 400.000 a&#241;os, sin embargo, un estudio (3) publicado esta semana

 &lt;P align=left&gt;pasada en Science va m&#225;s atr&#225;s en el tiempo y calcula que el nivel de di&#243;xido de

 &lt;P align=left&gt;carbono actual es el m&#225;s alto de los &#250;ltimos 2.1 millones de a&#241;os. El estudio podr&#237;a

 &lt;P align=left&gt;descartar la teor&#237;a de que la causa de las glaciaciones terrestres haya sido la ca&#237;da

 &lt;P align=left&gt;en los niveles de CO2. Pero, por otra parte, confirma que esos mayores niveles del

 &lt;P align=left&gt;gas coincidieron con intervalos de temperaturas m&#225;s altas en el planeta.

 &lt;P align=left&gt;El gas invernadero (4) se ha ido incrementando desde la revoluci&#243;n industrial desde

 &lt;P align=left&gt;280 ppm a las 390 ppm actuales por la quema de combustibles f&#243;siles y por la

 &lt;P align=left&gt;deforestaci&#243;n. El di&#243;xido de carbono es absorbido por el mar y las plantas en la

 &lt;P align=left&gt;fotos&#237;ntesis, devolviendo ox&#237;geno y creando las estructuras biol&#243;gicas de los &#225;rboles

 &lt;P align=left&gt;y plantas, pero el aumento por la actividad humana es superior a la capacidad de

 &lt;P align=left&gt;absorci&#243;n de la biosfera. Por otro lado, en el oc&#233;ano la absorci&#243;n est&#225; alcanzando

 &lt;P align=left&gt;su l&#237;mite y est&#225; provocando la acidificaci&#243;n de los oc&#233;anos.

 &lt;P align=left&gt;En este punto, es necesario aclarar que el principal de efecto invernadero es el

 &lt;P align=left&gt;vapor de agua, aunque &#233;ste tiene grandes variaciones espaciales y temporales

 &lt;P align=left&gt;dependiendo de la zona. Por ejemplo, su concentraci&#243;n es m&#225;xima en la zona

 &lt;P align=left&gt;ecuatorial y cerca del mar. Por el contrario, es m&#237;nima en los desiertos y en los

 &lt;P align=left&gt;polos ya que las bajas temperaturas admiten muy poca concentraci&#243;n de vapor de

 &lt;P align=left&gt;agua. Por ello, en los desiertos la oscilaci&#243;n t&#233;rmica es muy acusada, porque hay

 &lt;P align=left&gt;un gran calentamiento durante el d&#237;a, pero no hay nada que retenga la radiaci&#243;n

 &lt;P align=left&gt;infrarroja hacia el espacio durante la noche y en estas zonas, dicha oscilaci&#243;n

 &lt;P align=left&gt;t&#233;rmica diaria puede llegar hasta los 35 grados, llegando a helar en algunas zonas

 &lt;P align=left&gt;del desierto, para alcanzarse luego 40 grados cent&#237;grados.

 &lt;P align=left&gt;El tiempo medio de duraci&#243;n del vapor de agua en la atm&#243;sfera es mucho menor

 &lt;P align=left&gt;que el di&#243;xido de carbono que tiende a difundirse por la atm&#243;sfera tras ser emitido

 &lt;P align=left&gt;desde las industrias o el transporte. Adem&#225;s, del aumento de la concentraci&#243;n de

 &lt;P align=left&gt;di&#243;xido de carbono en la atm&#243;sfera, tambi&#233;n se est&#225;n registrando aumento de otros

 &lt;P align=left&gt;gases invernadero como el metano (procedente de la industria ganadera), el &#243;xido

 &lt;P align=left&gt;nitroso (procedente principalmente de la industria agr&#237;cola) y los

 &lt;P align=left&gt;clorofluorocarbonos.

 &lt;P align=left&gt;Nos quedan 90 meses (5), 7 a&#241;os y medio para estabilizar y reducir las

 &lt;P align=left&gt;concentraciones de gases invernadero por debajo de niveles que no supongan

 &lt;P align=left&gt;disparar mecanismos de retroalimentaci&#243;n que hagan el calentamiento global

 &lt;P align=left&gt;imparable (6).

The "ozone hole" is a severe depletion of the ozone layer high above Antarctica. It is primarily caused by human-produced compounds that release chlorine and bromine gases in the stratosphere. The ozone layer acts to protect life on Earth by blocking harmful ultraviolet rays from the sun.

The image at left is a view of the most recent Antarctic ozone hole, derived from satellite measurements that monitor the ozone layer. The blue and purple colors are where there is the least ozone, and the greens, yellows, and reds are where more ozone is present.

There are signs that ozone depletion is slowing in response to the 1987 Montreal Protocol, which resulted in a significant reduction in global emissions of ozone-depleting chemicals. However, climate change may cause the ozone hole to expand further&lt;/TD&gt;&lt;/TR&gt;&lt;/TBODY&gt;&lt;/TABLE&gt;
