2. 1. Ideological roots of climate change denial : Resistance to change, acceptance of inequality, or both?

   Author : Kirsti Maria Jylhä; Nazar Akrami; Mats Fredrikson; Christopher Cohrs; Uppsala universitet; []
   Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Climate change denial; ideology; political orientation; social dominance orientation; dominance of nature; personality; gender; Psychology; Psykologi;

   Abstract : Climate change denial has been found to correlate with sociopolitical ideology. The general aim of the present thesis was to investigate this relation, and more specifically to 1) test the unique effects of intercorrelated ideological variables on denial, and 2) investigate the psychological underpinnings of the ideology-denial relation.

4. 2. Tree Rings as Sensitive Proxies of Past Climate Change

   Author : Håkan Grudd; Wibjörn Karlén; Brian Luckman; Stockholms universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Tree ring; width; density; climate; temperature; change; variability; sensitivity; Torneträsk; Tornetrask; Sweden; Fennoscandia; explosive; volcanic; eruption; Santorini; Thera; subfossil; Fitzroya; Chile; Physical geography; Naturgeografi;

   Abstract : In the boreal forests of the Northern Hemisphere, time series of tree-ring width (TRW) and maximum density in the latewood (MXD) are highly correlated to local instrumental summer-temperature data and are thus widely used as proxies in high-resolution climate reconstructions. Hence, much of our present knowledge about climatic variability in the last millennium is based on tree-rings. READ MORE

5. 3. Uncertainties in tropical precipitation and radiative feedbacks under climate change

   Author : Alejandro Uribe Cortes; Thorsten Mauritsen; Frida Bender; Caroline Muller; Stockholms universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Climate change; radiative feedback; tropical precipitation; tropical extreme precipitation; climate modeling; Atmospheric Sciences and Oceanography; atmosfärvetenskap och oceanografi;

   Abstract : Clouds have a significant impact on climate. They contribute to controlling the planetary energy balance, and the precipitation distribution. Global Climate Models (GCMs) designed to reproduce the state of the climate system, however, have difficulties representing clouds. READ MORE

6. 4. Model analysis of ocean carbon storage and transport across climate states

   Author : Malin Ödalen; Jonas Nycander; Johan Nilsson; Kevin I. C. Oliver; Nathaelle Bouttes-Mauhourat; Stockholms universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Oceanography; Climate; Climate model; Carbon cycle; Paleoclimate; atmosfärvetenskap och oceanografi; Atmospheric Sciences and Oceanography;

   Abstract : The ocean carbon cycle plays a fundamental role in the Earth’s climate system, on decadal to multi-millennial timescales. Of the carbon held in the ocean, the atmosphere, and the terrestrial biosphere combined, more than 90% resides in the ocean. Carbon enters the surface ocean through air-sea gas exchange and from terrestrial sources. READ MORE

7. 5. Grasslands in a changing climate : Summer drought and winter warming effects on grassland vegetation

   Author : Nina Roth; Sara A. O. Cousins; Carly Stevens; Stockholms universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; biodiversity; climate change; compost; floral resources; grasslands; in-situ experiments; mowing; nectar; open-top chambers; plants; rain-out shelters; sheep grazing; soil amendments; summer drought; winter warming; naturgeografi; Physical Geography;

   Abstract : Grasslands harbour a high biodiversity of both plants and animals, and they provide many ecosystem services such as fodder production, pollination, and carbon storage. Climate change is likely to alter grassland ecosystems, with the effects varying according to the exact nature and timing of changes. READ MORE
