Vulnerability to Extreme Weather The Centre for Australian Weather and Climate ResearchA partnership between CSIRO and the Bureau of Meteorology
Extreme Weather • Severe Storms • Flooding • Storm damage – due to wind and/or rain • Hail damage • Tornadoes • Tropical Cyclones (Hurricanes, Typhoons) • Strong winds can destroy buildings, crops, and cause large waves. • Extreme rain rates can lead to flooding • Low pressures can produce storm surge and inundation The Centre for Australian Weather and Climate ResearchA partnership between CSIRO and the Bureau of Meteorology

Eruption of Laki ("Skaftá fires") The Centre for Australian Weather and Climate ResearchA partnership between CSIRO and the Bureau of Meteorology
Icelandic Haze Famine of 1783 Iceland Mist Hardships - 20–25% of the population died in the famine. 80% of sheep, 50% of cattle and 50% of horses died because of fluorosis from the 8 million tons of hydrogen fluoride release. The Centre for Australian Weather and Climate ResearchA partnership between CSIRO and the Bureau of Meteorology
Icelandic Haze Famine of 1783 Monsoon regions Laki eruption weakened African and Indian monsoon circulations, leading to between 1 and 3 millimetres less daily precipitation than normal over the Sahel of Africa, resulting in, among other effects, low flow in the River Nile. Thus famine in Egypt in 1784. . The Centre for Australian Weather and Climate ResearchA partnership between CSIRO and the Bureau of Meteorology
Icelandic Haze Famine of 1783 Europe Sulfur dioxide during unusual weather conditions caused a thick haze to spread across western Europe, resulting in many thousands of deaths throughout 1783 and the winter of 1784. The Centre for Australian Weather and Climate ResearchA partnership between CSIRO and the Bureau of Meteorology
Icelandic Haze Famine of 1783 North America The winter of 1784 was the longest and one of the coldest on record. It was the longest period of below-zero temperatures in New England, with the largest accumulation of snow in New Jersey and the longest freezing over of the Chesapeake Bay. An extreme snowstorm hit the south, the Mississippi River froze at New Orleans and there was ice in the Gulf of Mexico. .

Climate Change and Chill units • Already there is evidence that climate change is impacting on the apple and pear industries, with increased climate variability and reduced chilling hours, which are necessary for quality fruit production. • The Huon Valley of Tasmania has shown an increase in average minimum temperatures from 1950 of about 0.6°C across both summer and winter. • At Orange, NSW, the winter (May to October) average minimums have also risen by 0.6°C • The Goulburn Valley Victoria has experienced a decline in the average number of days with minimums below 7°C indicating a reduction in winter chill units http://www.aph.gov.au/binaries/senate/committee/rrat_ctte/climate_change/submissions/sub23.pdf The Centre for Australian Weather and Climate ResearchA partnership between CSIRO and the Bureau of Meteorology

Batlow - a cool region: Although chill is prolonged, warming in spring still dominates leading to earlier bloom time. Darbyshire et al. in press
Where does the uncertainty lie? • A greater proportion of the uncertainty in climate change impact projections was due to variations among crop models than to variations among downscaled general circulation models • S.

Rosenzweig, et al. • Uncertainty in simulating wheat yields under climate change • Nature Climate Change(2013) • DOI: • doi:10.1038/nclimate1916 The Centre for Australian Weather and Climate ResearchA partnership between CSIRO and the Bureau of Meteorology

WeatCliFS • The International Union of Geodesy and Geophysics (IUGG) is leading the WeatCliFS consortium of international scientific unions to examine weather, climate and food security as well as to look at the interaction of food security and geophysical phenomena. The following fundamental question underpins WeatCliFS: • What technologies and methodologies are required to assess the vulnerability of people and places to hazards [such as famine] – and how might these be used at a variety of spatial and temporal scales?
