  • Analogical development of Livonian i -adjectives

    Open AccessPatrick O’RourkeARTICLEEesti ja soome-ugri keeleteaduse…2025

    This article presents both a diachronic and synchronic explanation for the occurrence of the suffix -i in Livonian adjectives. The suffix is prevalent among Livonian adjectives and in most cases it can be derived directly from the Finnic suffix *-in(En), such as Courland Livonian roudi ‘of iron’

  • Lounaisitämerensuomalaiset denominaalit johtimet *-As (

    Open AccessPatrick O’RourkeARTICLEUralica Helsingiensia2024

    Southwest Finnic denominal derivative suffixes *-As (: *-AhA-), *-k̆As and *-k̆kAsIn this article, I examine Southwest Finnic variants of the derivative suffixes *-As (: *-AhA-), *-k̆As and *-k̆kAs. The suffixes themselves are common in Finnic, but the distribution of certain words formed with the suffixes gives reason to assume a local development of the use of the suffixes. Southwest Finnic linguistic forms mentioned in the article are Courland…

  • The hydrogen economy can reduce costs of climate change mitigation by up to 22

    Open AccessPaul Wolfram, Page Kyle et al.ARTICLEOne Earth2024

    In response to the urgent need to mitigate climate change via net-zero targets, many nations are renewing their interest in clean hydrogen as a net-zero energy carrier. Although clean hydrogen can be directly used in various sectors for deep decarbonization, the relatively low energy density and high production costs have raised doubts as to whether clean hydrogen development is worthwhile. Here, we improve on the GCAM model by including a more c…

  • Ambitious efforts on residual emissions can reduce CO 2 removal and lower peak temperatures in a net-zero future

    Open AccessJay Fuhrman, Simone Speizer et al.ARTICLEEnvironmental Research Letters2024

    Carbon dioxide removal (CDR) is expected to play a critical role in reaching net zero CO 2 and especially net zero greenhouse gase (GHG) emissions. However, the extent to which the role of CDR in counterbalancing residual emissions can be reduced has not yet been fully quantified. Here, we use a state-of-the-art integrated assessment model to develop a ‘Maximum Sectoral Effort’ scenario which features global emissions policies alongside ambitious…

  • Helping the climate by replacing liquefied natural gas with liquefied hydrogen or ammonia

    Open AccessPaul Wolfram, Patrick O’Rourke et al.ARTICLEEnvironmental Research Letters2024

    The war in Ukraine caused Europe to more than double its imports of liquefied natural gas (LNG) in only one year. In addition, imported LNG remains a crucial source of energy for resource-poor countries, such as Japan, where LNG imports satisfy about a quarter of the country’s primary energy demand. However, an increasing number of countries are formulating stringent decarbonization plans. Liquefied hydrogen and liquefied ammonia coupled with car…

  • The role of direct air capture and negative emissions technologies in the shared socioeconomic pathways towards +1.5 °C and +2 °C futures

    Open AccessJay Fuhrman, Andrés F Clarens et al.ARTICLEEnvironmental Research Letters2021

    The development of the Shared Socioeconomic Pathways (SSPs) and associated integrated assessment modeling (IAM) exercises did not include direct air capture with carbon storage (DACCS) in their scenarios. However, recent more optimistic cost estimates and commercial or pilot-scale DACCS plants have led to increased attention to this technology in both IAM literature and in real-world policy discussions. DACCS is an energy-consuming negative emiss…

  • Historical (1750–2014) anthropogenic emissions of reactive gases and aerosols from the Community Emissions Data System (Ceds)

    Open AccessRachel Hoesly, Steven J Smith et al.ARTICLEGeoscientific Model Development2018

    We present a new data set of annual historical (1750–2014) anthropogenic chemically reactive gases (CO, CH4, NH3, NOx, SO2, NMVOCs), carbonaceous aerosols (black carbon – BC, and organic carbon – OC), and CO2 developed with the Community Emissions Data System (CEDS). We improve upon existing inventories with a more consistent and reproducible methodology applied to all emission species, updated emission factors, and recent estimates through 2014.…

  • Livonian features in Estonian dialects

    Open AccessPatrick O’Rourke, Karl PajusaluARTICLEEesti ja soome-ugri keeleteaduse…2016References: 4

    This article presents linguistic innovations which are typical of both Courland and Salaca Livonian and are also known in the neighbouring Estonian dialect areas. These innovative features are phonological, morphological, and morphosyntactic. The features are present mainly in western and southwestern Estonia, but also more specifically in areas close to the current western border between Estonia and Latvia. This article discusses the nature and …
