Can ozone depletion and global warming interact to produce rapid climate change?

The atmosphere displays modes of variability whose structures exhibit a strong longitudinally symmetric (annular) component that extends from the surface to the stratosphere in middle and high latitudes of both hemispheres. In the past 30 years, these modes have exhibited trends that seem larger than their natural background variability, and may be related to human influences on stratospheric ozone and/or atmospheric greenhouse gas concentrations. The pattern of climate trends during the past few decades is marked by rapid cooling and ozone depletion in the polar lower stratosphere of both hemispheres, coupled with an increasing strength of the wintertime westerly polar vortex and a poleward shift of the westerly wind belt at the earth's surface. Annular modes of variability are fundamentally a result of internal dynamical feedbacks within the climate system, and as such can show a large response to rather modest external forcing. The dynamics and thermodynamics of these modes are such that strong synergistic interactions between stratospheric ozone depletion and greenhouse warming are possible. These interactions may be responsible for the pronounced changes in tropospheric and stratospheric climate observed during the past few decades. If these trends continue, they could have important implications for the climate of the 21st century.

Global warming in the twenty-first century: An alternative scenario

A common view is that the current global warming rate will continue or accelerate. But we argue that rapid warming in recent decades has been driven mainly by non-CO2 greenhouse gases (GHGs), such as chlorofluorocarbons, CH4, and N2O, not by the products of fossil fuel burning, CO2 and aerosols, the positive and negative climate forcings of which are partially offsetting. The growth rate of non-CO2 GHGs has declined in the past decade. If sources of CH4 and O3 precursors were reduced in the future, the change in climate forcing by non-CO2 GHGs in the next 50 years could be near zero. Combined with a reduction of black carbon emissions and plausible success in slowing CO2 emissions, this reduction of non-CO2 GHGs could lead to a decline in the rate of global warming, reducing the danger of dramatic climate change. Such a focus on air pollution has practical benefits that unite the interests of developed and developing countries. However, assessment of ongoing and future climate change requires composition-specific long-term global monitoring of aerosol properties.

The observed global warming record: What does it tell us?

Global, near-surface temperature data sets and their derivations are discussed, and differences between the Jones and Intergovernmental Panel on Climate Change data sets are explained. Global-mean temperature changes are then interpreted in terms of anthropogenic forcing influences and natural variability. The inclusion of aerosol forcing improves the fit between modeled and observed changes but does not improve the agreement between the implied climate sensitivity value and the standard model-based range of 1.5–4.5°C equilibrium warming for a CO2 doubling. The implied sensitivity goes from below the model-based range of estimates to substantially above this range. The addition of a solar forcing effect further improves the fit and brings the best-fit sensitivity into the middle of the model-based range. Consistency is further improved when internally generated changes are considered. This consistency, however, hides many uncertainties that surround observed data/model comparisons. These uncertainties make it impossible currently to use observed global-scale temperature changes to narrow the uncertainty range in the climate sensitivity below that estimated directly from climate models.

Tratamiento informativo del deporte femenino español en los Juegos Olímpicos en el diario ABC (1924-2012)

Los recientes éxitos del deporte femenino olímpico español (en los últimos Juegos Olímpicos de Londres 2012 hubo más medallas de mujeres que de hombres) están empezando a tener su repercusión en los medios de comunicación, tanto en la cantidad como en la calidad de las informaciones. Salvando las constantes inherentes a los deportes minoritarios (sólo se habla de ellos cada cuatro años, eclipsados el resto de la Olimpiada por el fútbol), sí que se está produciendo un cambio de actitud hacia las especialidades femeninas. Los Medios de Comunicación les dedican más atención y las deportistas disfrutan de más popularidad mediática. Además, los éxitos olímpicos han continuado en otras competiciones (Europeos, Mundiales…) y se siguen con interés los campeonatos en los que participan las españolas. Hace años, era impensable que los MM.CC. se hicieran eco de un Europeo de balonmano femenino o de uno de piscina corta, como ahora sucede. Y el interés por las actividades deportivas de las féminas sigue creciendo en función de los buenos resultados. Precisamente, para analizar lo que ha sido esta evolución en las citas olímpicas vamos a centrarnos en el estudio de las informaciones femeninas en todos los Juegos Olímpicos en el Diario ABC, el más veterano de los de tirada nacional. Esto nos va a permitir estudiar el tratamiento informativo que se les ha dado a estas deportistas a lo largo de la historia. Dado que la primera aparición femenina sucedió en París 1924, este periódico es ideal para este fin. Se han analizado todas las páginas de los Juegos Olímpicos en los que ha habido representación femenina española (desde París 1924 hasta Londres 2012) y contabilizado sus resultados de modo cuantitativo, tanto por deportes como por espacio, y cualitativo, por la relevancia de las mismas...

La salud pública en el marco de la administración periférica: el Instituto Provincial de Higiene de Alicante (1924-1936)

Se describe el desarrollo del Instituto Provincial de Higiene de Alicante. En una primera parte se pasa revista al marco normativo nacional que dio lugar a la constitución y a las sucesivas reorganizaciones de los Institutos Provinciales de Higiene. En la segunda parte, utilizando materiales de archivo, reconstruimos la vida del Instituto Provincial de Higiene, desde sus antecedentes como Brigada Sanitaria Provincial hasta el inicio de la Guerra Civil, estudiando las fases en las que dependió de la Diputación Provincial, y, posteriormente con la República, de la Mancomunidad de Municipios.
