Actualmente ¿hay alguna relación entre calentamiento global antropogénico y precipitaciones? Yo no la veo:

Interesante hilo, buen trabajo!

Una pregunta

¿Alguien podría buscar una gráfica dela evolución de la lluvia mensual o anual hasta 2007-2007?

Es que sólo he encontrado hasta 1990

Gracias de antemano

yo tengo una  de estimación del ciclo del agua de todo el holoceno, cuando la encuentre te la pongo

Changes in the variability of global land precipitation

In our warming climate there is a general expectation that the variability of precipitation (P) will increase at daily, monthly and inter-annual timescales. Here we analyse observations of monthly P (1940–2009) over the global land surface using a new theoretical framework that can distinguish changes in global P variance between space and time. We report a near-zero temporal trend in global mean P. Unexpectedly we found a reduction in global land P variance over space and time that was due to a redistribution, where, on average, the dry became wetter while wet became drier. Changes in the P variance were not related to variations in temperature. Instead, the largest changes in P variance were generally found in regions having the largest aerosol emissions. Our results combined with recent modelling studies lead us to speculate that aerosol loading has played a key role in changing the variability of P.
