Announcement: Chemistry Climate Model Initiative Summer School and Workshop 2019

We are pleased to announce that the 2019 science workshop of the joint SPARC-IGAC project the Chemistry Climate Model Initiative (CCMI) will take place August 7 – 9, 2019 on the campus of the Chinese University of Hong Kong (CUHK) in Hong Kong. The meeting is very generously being hosted by Prof. Amos Tai and his research group, the Institute of Environment, Energy and Sustainability and the Earth System Science Program of the Faculty of Science at CUHK. In addition to invited and contributed presentations covering recent developments in chemistry-climate interactions, discussions will be held on the science questions and policy needs, simulations and outputs for a CCMI Phase Two.

Before the workshop, August 4 – 6, CCMI will be holding a summer school titled Earth system modelling and observations to study Earth in a changing climate. Lectures will focus on developing a critical understanding of the strengths and weaknesses of Earth-system observations and chemistry-climate models. The summer school will include a significant practical component to provide participants with an introduction to the tools and methods used to analyse model output fields (netCDF) that are publicly available within the CCMI-1 archive, including examples of how to use Earth observations to assess these models with the goal of improving our understanding of chemistry-climate processes. The summer school places a strong emphasis on capacity building and early career scientists from developing countries are strongly encouraged to apply. Some limited funds to support travel is available and the summer school will be limited to approximately 20 participants.

Please check the CCMI website (http://blogs.reading.ac.uk/ccmi/) for further details on both the science workshop and the summer school and for information on how you can participate in the discussions on the next phase of CCMI in the lead-up to the workshop.

15 African researchers to receive £1.5M to conduct research on impacts of climate change in Africa

In October 2018, the Intergovernmental Panel on Climate Change (IPCC) published its Special Report on the Implications of 1.5 degrees warming (SR 1.5), and shortly thereafter UN Environment published its 2018 Emissions Gap Report. The SR 1.5 concludes that the projected impacts of 2 degrees warming are more dangerous than initially thought and brings us closer to several critical tipping points. The report also cautions that we have only 12 years for drastic action if we are to have any chance of achieving the 1.5 degrees’ target. The UN Environment’s Emissions Gap Report establishes that, despite progress made in the global climate governance regime, greenhouse gas emissions are once again on the increase.

More than any other continent, Africa is already bearing the impact of the instability of the climate system as evidenced by increasingly unpredictable patterns of precipitation and high temperatures. These trends have devastating impacts on the continent’s economies, livelihoods and ecosystems. Drastic and urgent climate action is required to ensure that the continent does not experience worsening climate related devastation and retains some capacity to meet its development aspirations.  Drastic climate action will require the engagement of all sectors, interests and stakeholders. A key gap in climate policy and governance in Africa is the weak linkage between science and policy. This gap must be addressed urgently to ensure that development strategies, policies and programmes are climate informed.

The African Academy of Sciences (The AAS), the United Kindgoms’ Department for International Development (DFID) Weather and Climate information SERvices for Africa (WISER) programme and the Africa Climate Policy Centre (ACPC) of the United Nations Economic Commission for Africa are today announcing the implementation of a multimillion dollar initiative to support Africa-led climate science research through the Climate Research for Development (CR4D) in Africa initiative. The CR4D initiative was conceptualized at the Africa Climate Conference in 2013 as a mechanism to strengthen links between climate science research and climate information needs to support development planning in Africa. The initiative addresses climate research priority areas that have been identified in Africa by African researchers.

Over the next year, CR4D will support research into identified priority areas for climate change and development linkages. The research will cover foundational climate science, impacts, information and research translation and engagement with policy and decision-making communities. The goal will be to produce research outputs that inform policy in climate sensitive sectors to better prepare Africa to deal with the impacts of climate change.

Dr James Murombedzi of the ACPC noted that “While Africa is responsible for only 4% of global greenhouse-gas emissions, 65% of the African population is directly impacted by climate change. It is therefore imperative that climate action must be stepped up to deliver high impact outcomes for African populations, and to ensure the resilience of economies, ecosystems and infrastructure on the continent. The framework for scaling up climate action was put in place in the 2015 Paris Agreement. The realization of the ideals of this agreement will be determined by the national frameworks, strategies and policies that are put in place to implement national and sub-national climate actions. The CR4D initiative will enhance support for improved climate information and services to contribute to climate sensitive planning. This, in turn, will contribute towards ensuring human and environmental security, improved investment policies, as well as institutional developments to manage potential threats from climate change.”

The Executive Director of The AAS, Prof. Nelson Torto says, “With smallholder farms, most being rainfed, forming about 80% of farmed land in sub-Saharan Africa and given that most of sub-Saharan Africa’s population draws its livelihood from smallholder farming,[1] the CR4D initiative will be a huge addition to Africa’s quest to transform itself through science. Tackling climate change in Africa requires that African researchers are supported to ensure they have the best understanding of the problems to be better prepared to provide and amplify solutions. The AAS is particularly proud to be part of this noble initiative and we look forward to celebrating its impact in all climate sensitive sectors including agriculture, health, water resources, tourism and other areas of socio-economic development.”

CR4D will award 1-year research grants to 15 African climate researchers of up to USD 130,000. Through The AAS Rising Research Leaders programme, grantees will be supported to develop as independent research leaders through training, mentoring, and networking opportunities that will enable international collaborations. CR4D candidates must be hosted by or affiliated with a university, research institute or other eligible institution of higher education in Africa. They must hold a PhD in climate or related sciences and/or have a proven track record of high-quality, impactful research in a relevant field. Applicants must have a clearly defined scientific research proposal and all African nationals are eligible to apply.

A call for proposals for CR4D has been issued and is open from 18 January to 10 February 2019. The call is accessible here https://aasishango.ccgranttracker.com/Login.aspx?ReturnUrl=/
