Environmental context. The idea that gases produced by plankton living in the oceans can affect cloudiness and regulate climate was given prominence by the promulgation more than 20 years ago by Charlson, Lovelock, Andreae and Warren of the CLAW hypothesis. In the intervening period it has been difficult to prove or disprove the idea, although much research has flowed from its enunciation. Perhaps its lasting legacy is in the way we view the planet and how research is conducted to try to understand how it operates.

This article attempts to understand the way in which climate change affects the once dry cold desert of Ladakh and how local communities have adapted to these changes by becoming excellent organic gardeners. The contributions of Sonam Wangchuk and his work with regard to water harvesting and alternative education have been recognised by the Ramon Magsaysay Committee for 2018. This will propel Sonam to complete his life mission, which is the construction of a whole new township in Phey, to relieve Leh of the overload it now experiences. The article provides a background to the work of Sonam and his wife Rebecca Norman in the details of everyday life and work, which they bring to their school, SECMOL.

Significance National GDP nevertheless contracted by just 1.5% in 2020 -- less than almost any other country in Latin America. Resilient remittances and exports, coupled with unprecedented policy support, have mitigated the effects of the pandemic and subsequent containment measures, leaving the country better placed for recovery than its neighbours. Impacts Enduring poverty, inequality and violent crime, and the impacts of accelerating climate change, will drive further migration from Guatemala. The government will pursue banking law reforms, to reduce risks to financial activities in the post-pandemic business environment. Infighting and corruption scandals will hinder the opposition's ability to benefit from the decline of the president's popularity.

This study documented stakeholders’ perception on the changing rainfall pattern in southeast Nigeria. The paper collected data from many stakeholders across Nigeria. Stakeholders’ view about changing rainfall pattern using the December 2013 event was presented. Most of the stakeholders attributed the increasing number of rainy days in December 2013 to climate change. The stakeholders also believed that this new rainfall pattern will impact on different economic sectors and activities. Various adaptation strategies were recommended as the way to manage the risks that may accompany the recent rainfall pattern.

Abstract Providing reliable information on climate change at local scale remains a challenge of first importance for impact studies and policymakers. Here, we propose a novel hybrid downscaling method combining the strengths of both empirical statistical downscaling methods and Regional Climate Models (RCMs). The aim of this tool is to enlarge the size of high-resolution RCM simulation ensembles at low cost.We build a statistical RCM-emulator by estimating the downscaling function included in the RCM. This framework allows us to learn the relationship between large-scale predictors and a local surface variable of interest over the RCM domain in present and future climate. Furthermore, the emulator relies on a neural network architecture, which grants computational efficiency. The RCM-emulator developed in this study is trained to produce daily maps of the near-surface temperature at the RCM resolution (12km). The emulator demonstrates an excellent ability to reproduce the complex spatial structure and daily variability simulated by the RCM and in particular the way the RCM refines locally the low-resolution climate patterns. Training in future climate appears to be a key feature of our emulator. Moreover, there is a huge computational benefit in running the emulator rather than the RCM, since training the emulator takes about 2 hours on GPU, and the prediction is nearly instantaneous. However, further work is needed to improve the way the RCM-emulator reproduces some of the temperature extremes, the intensity of climate change, and to extend the proposed methodology to different regions, GCMs, RCMs, and variables of interest.

Meeting the needs of a growing world population in the face of imminent climate change is a challenge; breeding of vegetable and oilseed Brassica crops is part of the race in meeting these demands. Available genetic diversity constituting the foundation of breeding is essential in plant improvement. Elite varieties, land races, and crop wild species are important resources of useful variation and are available from existing genepools or genebanks. Conservation of diversity in genepools, genebanks, and even the wild is crucial in preventing the loss of variation for future breeding efforts. In addition, the identification of suitable parental lines and alleles is critical in ensuring the development of resilient Brassica crops. During the past two decades, an increasing number of high-quality nuclear and organellar Brassica genomes have been assembled. Whole-genome re-sequencing and the development of pan-genomes are overcoming the limitations of the single reference genome and provide the basis for further exploration. Genomic and complementary omic tools such as microarrays, transcriptomics, epigenetics, and reverse genetics facilitate the study of crop evolution, breeding histories, and the discovery of loci associated with highly sought-after agronomic traits. Furthermore, in genomic selection, predicted breeding values based on phenotype and genome-wide marker scores allow the preselection of promising genotypes, enhancing genetic gains and substantially quickening the breeding cycle. It is clear that genomics, armed with diversity, is set to lead the way in Brassica improvement; however, a multidisciplinary plant breeding approach that includes phenotype = genotype × environment × management interaction will ultimately ensure the selection of resilient Brassica varieties ready for climate change.

This chapter synthesizes the book’s themes of contextualizing climate change in community realities, reflecting on the five climate reductionisms introduced in the opening chapter and taking actionable progress toward policy change. Though climate change is a wicked problem, characterized by uncertainty and complexity, the way forward for socially just solutions must include purposeful, meaningful partnerships with communities in ways that recognize their own inherent diversity, value their knowledge, and address their manifold needs. However, partnerships for policy change might be conceived as a wicked “solution”: They will involve many stakeholders, there is little precedent for how to make them successful, and there are still questions of whether they are needed in all phases of the policy process or for all policy decisions.
