Winter climate response to continental snow anomalies
Climate variability has emerged in recent decades as an important field of geoscience research. A thorough understanding of the patterns and causes of climate variability is required to predict and prepare for upcoming climatic shifts, and also to accurately distill anthropogenic climate change …

Investigating the atmospheric composition and climate response to mitigation: a methane emissions-driven approach
… an attractive option for near-term mitigation of climate change. Methane is also a key tropospheric ozone precursor: ozone is a greenhouse gas, and acts as an air pollutant in the troposphere. Therefore, mitigation of methane has both climate and air quality benefits. A new configuration of the UK …

Evaluating the relationship between the temperature response to volcanic aerosols and climate sensitivity
Climate sensitivity is an important concept in climate science, but its estimated value has considerable uncertainty. Some previous studies have argued for a link between the temperature response to volcanic radiative forcing and climate sensitivity. Bender et al. (2010) showed that equilibrium …

Climate change & society in conflicted landscapes: Cases of Srinagar (Kashmir) and Jerusalem (West Bank, Palestine)
Climate change has become an important part of social, political and economic policy post the Paris Climate Agreement of 2016. The Agreement recognizes the urgency for action at a global scale. Major superpowers, developing countries and a host of nations in-between are parties to this agreement. …

A vertically-integrated approach to climate science : from measurements and machine learning to models and policy
… of understanding past, present, and future climate. Studying how these particles influence ice cloud formation requires careful measurement of their ice nucleating ability as well as robust uncertainty quantification of experimental results. These measurements and their corresponding …

Invariant Manifolds of a Toy Climate Model
… glacier/temperature interaction of an idealized climate was studied. Self sustained oscillation of the autonomous equation was used to model the internal mechanisms that could produce these fluctuations. Periodic parametric modulation of a damped internal oscillation was used to model periodic …

The Combined Role of ENSO-driven Sea Surface Temperature Variation and Arctic Sea Ice Extent in Defining Climate Conditions in the Southwestern United States
… tracks, precipitation patterns, and overall climate conditions in the American southwest. We find that tropical Pacific SSTs greatly influence climate system response to variability in Arctic SIC, with ENSO-Neutral SSTs permitting the greatest response. Additionally, the degree of expansion …

Investigating Palaeoatmospheric Composition-Climate Interactions
… history, with important implications for past climate. A number of case studies will be presented which employ coupled climate model simulations to assess the strength of these chemical feedbacks on the climate. The eruption of Mount Samalas in 1257 led to the largest stratospheric volcanic …

Application of a New Tree-Ring Based Drought Reconstruction Method at Multiple Forest Sites Across Indiana, U.S.A.
… using multiple co-occurring species (MCOS) in a climate reconstruction model compared to a single species (SS) in four old-growth forests in Indiana: Pioneer Mothers Memorial Forest (PM), Donaldson Woods (DW), Hoot Woods (HW), and Lilly Dickey Woods (LD). The objectives of this study were to [1] …

An Investigation Of Cloud Processes Relevant To Climate Sensitivity
… source of uncertainty in predicting the Earth's climate response to CO2 radiative forcing. Various global climate models estimate that this response amplifies the initial CO2 forcing by a factor between 2 and 5. The research in this dissertation aims to better understand cloud processes that have …

Radial growth patterns of jack pine in relation to climate, moisture availability, and dwarf mistletoe infection in the Boreal Plains Ecozone of Saskatchewan, Canada
Drought stress is increasing as a result of climate change, and is thought to be driving episodes of tree mortality that have been observed in every forested region on Earth. In the western boreal forest, potential interactions between drought stress and forest diseases could lead to forest …

Towards zero emissions and zero poverty in the Global South: a comparative analysis of South Africa, India and Mexico's approach to development and climate change mitigation
… the 21st century are sustainable development and climate change mitigation. In light of these challenges, this thesis seeks to analyse and compare the extent to which development and climate change mitigation are aligned on a policy level in three countries in the global south, namely South …

Forward modeling of tree-climate relations across the Northern Hemisphere
… that directly predicts tree-ring growth using climate data, to simulate tree-ring formation across the Northern Hemisphere. Previous research has shown the model has skill in reproducing ring-width variability and climate sensitivity at local and regional scales, but its ability to simulate the …

‘Grounding' ecosystem-based adaptation in the Western Cape Province
… society's adaptation to the adverse impacts of climate change. The National Department of Environmental Affairs, Fisheries and Forestry in South Africa has decided to mainstream EbA into its climate response actions, developing a strategy and set of guidelines to steer implementation. However, …

A central Texas drying event identified at the Younger Dryas-early Holocene transition using coupled speleothem 𝛿¹³C-¹⁴C analysis
… is consistent with other Texas paleoclimate records, indicating a climate transition to drier early Holocene conditions. Compared with existing regional proxy records, the relatively high temporal resolution of the McN-1 𝛿¹³C record (inter-annual) indicates a rapid drying event …

Microbial communities and their response to Pleistocene and Holocene climate variabilities in the Russian Arctic
… is considered as a focal region in the ongoing climate change debate. The currently observed and predicted climate warming is particularly pronounced in the high northern latitudes. Rising temperatures in the Arctic cause progressive deepening and duration of permafrost thawing during the arctic …

The role of high-latitude oceans in transient climate change
… globally averaged sea surface temperature (SST) response to atmospheric forcing. We focus on the impact of anthropogenic greenhouse gases (AGHGs) and the Antarctic ozone hole and use output from general circulation models (GCMs) to estimate the corresponding climate response functions (CRFs). We …

Application of the hector-brick reduced complexity earth system model for probabilistic climate projection
Probabilistic climate assessments require robust characterizations of decision-relevant uncertainties. Reduced complexity climate models can be useful tools for quantifying uncertainty, given their flexibility, computational efficiency, and the ability to link these models with large-ensemble …

A Multi-scale Analysis of the Potential Impacts of Rapid Climate Change on Forest Lands Managed by the Department of Defense in the US
Based on current projections from global climate models (GCM's), regional climates in the coterminous U.S. are expected to become warmer and either wetter or drier over the next century depending on the GCM used to make projections. Forest communities and the species that comprise them are likely …

Reconstructing Australia’s late Quaternary climate from the geochemistry of lake sediments and snail shells
Australia’s climate is influenced by ocean-atmosphere interactions in the adjacent Indian, Pacific, and Southern oceans, as well as major atmospheric circulation patterns. Australian climates exhibit high inter-annual variability, arising in part from complex interactions between these drivers. …
