  • Global Climate Risk Index 2018
    THINK TANK & RESEARCH BRIEFING PAPER GLOBAL CLIMATE RISK INDEX 2018 Who Suffers Most From Extreme Weather Events? Weather-related Loss Events in 2016 and 1997 to 2016 David Eckstein, Vera Künzel and Laura Schäfer Global Climate Risk Index 2018 GERMANWATCH Brief Summary The Global Climate Risk Index 2018 analyses to what extent countries have been affected by the impacts of weather-related loss events (storms, floods, heat waves etc.). The most recent data available – for 2016 and from 1997 to 2016 – were taken into account. The countries affected most in 2016 were Haiti, Zimbabwe as well as Fiji. For the period from 1997 to 2016 Honduras, Haiti and Myanmar rank highest. This year’s 13th edition of the analysis reconfirms earlier results of the Climate Risk Index: less developed countries are generally more affected than industrialised countries. Regarding future climate change, the Climate Risk Index may serve as a red flag for already existing vulnerability that may further increase in regions where extreme events will become more frequent or more severe due to climate change. While some vulnerable developing countries are frequently hit by extreme events, for others such disasters are a rare occurrence. It remains to be seen how much progress the Fijian climate summit in Bonn will make to address these challenges: The COP23 aims to continue the development of the ‘rule-book’ needed for implementing the Paris Agreement, including the global adaptation goal and adaptation communication guidelines. A new 5-year-work plan of the Warsaw International Mechanism on Loss and Damage is to be adopted by the COP.

  • Evolution of the 2018 European Heat Wave
    Evolution of the 2018 European heat wave Stine Sagen Thesis submitted for the degree of Master of science in Meteorology and Oceanography 60 Credits Department of Geosciences Faculty of mathematics and natural sciences UNIVERSITY OF OSLO June 15, 2020 c 2020 Stine Sagen Evolution of the 2018 European heat wave This work is published digitally through DUO âĂŞ Digitale Utgivelser ved UiO http://www.duo.uio.no/ Printed: Reprosentralen, University of Oslo All rights reserved. No part of this publication may be reproduced or transmitted, in any form or by any means, without permission. Abstract This master study addresses the monthly evolution from April to September of the extreme heat wave that occurred in Europe in 2018. Heat waves cause serious hazards related to regional economics, ecosystems, human health and deaths. According to the large number of studies existing on heat waves, most climate models predict that in the future, heat waves will appear more often, last longer and increase in magnitude. Heat waves therefore require urgent attention and enhanced understanding of the processes behind this phenomenon is thus the motivation behind this thesis. The thesis will investigate how 1) atmospheric blocking was associated with a large-scale quasi-stationary mid-latitude flow regime and 2) soil moisture-temperature feedback could explain the anomalously high temperatures. To analyze these mechanisms and to see how they co-interact, a high resolution reanalysis dataset has been applied in order to provide a complete and consistent dataset. The main finding is that the strongest and most prolonged heat waves could mainly be identified in Northern Europe.

We use the WUI definitions developed for North America applied to a regular 1 km2 grid. The Census blocks, onto which the American WUI is evaluated do not exist for many countries so a method of evaluating the WUI would be valuable for many regions and nations across the world. The results follow expected patterns across the nation, the WUI is scattered over Sweden, but the greatest extent is found outside Stockholm and Gothenburg and in Blekinge county, mostly in the form if intermix WUI in which buildings are scattered within the wildland. For the Community level, the chosen method is too coarse and an adaptation is applied and exemplified on a rural village in southern Sweden.

The present study strives to provide a systematic review of recent studies of warm biometeorological extremes in Europe. The main aim of this paper is to provide a methodical summary of the observed changes in warm extremes, duration, and variability in different parts of Europe. During the last decade, much attention has been paid to the negative impacts of heat and humidity on human health. Therefore, the human biometeorology is required to appraise the human thermal environment in a way that human thermoregulation is taken into account. In many European countries and regions, future heat exposure will indeed exceed critical levels, and a steep increase in biometeorological heatwaves and warm extremes are expected.

Based on three drought indices (SPI, SPEI, Z-index) reconstructed from the documentary evidence and instrumental records, the summers of 1531–1540 were identified as the driest summer decade during the 1501–2015 period in the Czech Lands. Based on documentary data, extended from the Czech scale to central Europe, dry patterns of various 25 intensities (represented, for example, by dry spells, low numbers of precipitation days, very low rivers and drying-out of water sources) occurred in 1532, 1534–1536, 1538 and particularly 1540, broken by wetter or normal patterns in 1531, 1533, 1537 and 1539.
