COLOQUIO
Estimación de emisiones antropogénicas de gases de
efecto invernadero

Ignacio Pisso
National Institute for Envirnonmental
Studies (Japon)

Resumen:

Las emisiones de gases de efecto invernadero
provenientes de actividades humanas pueden modificar negativamente la
composición de la atmósfera. Para regular las actividades que los
generan, es necesario conocer la intensidad de las emisiones y de su
localización en el espacio y en el tiempo. En este coloquio examinaremos
algunos
métodos de estimación de emisiones antropogénicas de gases de
efecto invernadero incluyendo desarrollos recientes en alta
resolucion.

Lugar: Aula 8, 2º Piso, DCAO

Universitaria.

COLOQUIO EXTRAORDINARIO
EVALUATING GLOBAL CLIMATE RESPONSES TO
DIFFERENT FORCINGS USING SIMPLE INDICES

David Karoly
School of Earth
Sciences, University of Melbourne, Australia

Resumen:

The most common
indicator of global scale climate change is the global-mean surface air
temperature. There are several additional indices of global scale
temperature variations that are useful for distinguishing natural
internal climate variations from anthropogenic climate change (Karoly
and Braganza 2001, Drost et al., 2011). These include the contrast
between the average temperatures over land and over oceans, the
meridional temperature gradient in the Northern Hemisphere, and the
magnitude of the annual cycle of temperatures over land. They are nearly
independent of the global mean temperature for natural internal climate
variations at decadal time scales and represent different aspects of the
climate system, yet they show common responses to anthropogenic climate
change.

Here, I will report on analyses of the CMIP5 historical
simulations, comparing the decadal variability of the indices with that
from 3 observational datasets and from CMIP3 model simulations, as well
as comparing the trends of the indices over the last fifty years. The
CMIP5 greenhouse-gas-only and natural-only forcing runs for the
historical period are used to assess the climate responses in these
indices to greenhouse gas, natural and anthropogenic aerosol forcing
variations from the different models.

Professor David Karoly is an
internationally recognised expert in climate change and climate
variability, including greenhouse climate change, stratospheric ozone
depletion and interannual climate variations due to El Niño-Southern
Oscillation. He was heavily involved in preparation of the Fourth
Assessment Report of the Intergovernmental Panel on Climate Change
(IPCC) released in 2007, in several different roles. Professor Karoly is
a member of the new Climate Change Authority in Australia. He is also a
member of the Science Advisory Panel to the Australian Climate
Commission, the Wentworth Group of Concerned Scientists, and the Joint
Scientific Committee, which provides oversight of the World Climate
Research Programme.
