Fisher et al. (2012)––henceforth, FHRS––have uncovered coding and data errors in our paper, Deschênes and Greenstone (2007), henceforth, DG. We acknowledge and are embarrassed by these mistakes. We are grateful to FHRS for uncovering them. We hope that this Reply will also contribute to advancing the literature on the vital question of the impact of climate change on the US agricultural sector.

This paper measures the economic impact of climate change on US agricultural land by estimating the effect of random year-to-year variation in temperature and precipitation on agricultural profits. The preferred estimates indicate that climate change will increase annual profits by $1.3 billion in 2002 dollars (2002$) or 4 percent. This estimate is robust to numerous specification checks and relatively precise, so large negative or positive effects are unlikely. We also find the hedonic approach—which is the standard in the previous literature—to be unreliable because it produces estimates that are extremely sensitive to seemingly minor choices about control variables, sample, and weighting.

Assessing the level of socio-economic vulnerability focuses on the degree of different impacts due to the threats of climate change.The variables of the vulnerability function is a set of indicators.In the process of impact, differentindicatorshave different roles, expressed by the weight of indicators. The selected set of indicator includes 20 indicators. The weights of these indicators are calculated by Analytic Hierarchy Process with the support of Expert Choice software.The results show that the indicators related to natural disasters in the exposure variable, indicators related to crop areas in sensitive variables and indicators related to the prevention and mitigation of adverse impacts of Climate change and natural disasters play the most important role in assessing the vulnerability.The results of assessing the level of vulnerability caused by the impacts of climate change and the natural disasters of the indicators show that: 18 out of 20 districts in the province have medium level of vulnerability.Particularly, in the two districts of Tuong Duong and Thanh Chuong,due to thehigh impact of climate change and natural disastersin combination with the low capacity of adaptation in the agricultural sector, the synthetic vulnerability is assessed at a high level.

Separating the impact of climate change and human activities on runoff is an important topic in hydrology, and a large number of methods and theories have been widely used. In this paper, we review the current papers on separating the impacts of climate and human activities on runoff, summarize the progress of relevant research methods and applications in recent years, and discuss future research needs and directions.

Climate change may affect the use of pesticides and their associated environmental and human health impacts. This study employs and modifies a partial equilibrium model of the US agricultural sector to examine the effects of alternative regulations of the pesticide and greenhouse gas emission externality. Simulation results indicate that without pesticide externality regulations and low greenhouse gas emission mitigation strategy, climate change benefits from increased agricultural production in the US are more than offset by increased environmental costs. Although the combined regulation of pesticide and greenhouse gas emission externalities increases farmers' production costs, their net income effects are positive because of price adjustments and associated welfare shifts from consumers to producers. The results also show heterogeneous impacts on preferred pest management intensities across major crops. While pesticide externality regulations lead to substantial increases in total water use, climate policies induce the opposite effect.

Purpose The purpose of this study is to analyze the impact of climate change and variability on agricultural production in Middle East and North Africa region (MENA) where the deleterious impacts of climate change are generally projected to be greatest. Design/methodology/approach The study used a production function model using Fixed Effect Regression (FER) analysis and then using marginal impact analysis to assess the impact of climate change and variability on agricultural production. Therefore, the study utilized panel data for the period 1961-2009 pooled from 20 countries in MENA region. Findings Results showed that 1 per cent increase in temperature during winter resulted in 1.12 per cent decrease in agricultural production. It was also observed that 1 per cent increase in temperature variability during winter and spring resulted in 0.09 and 0.14 per cent decrease in agricultural production, respectively. Results also indicated that increasing precipitation during winter and fall season and precipitation variability during winter and summer seasons had negative impact. The estimated parameters of square temperature and precipitation indicated that climate change has significant nonlinear impacts on agricultural production in MENA region. Originality/value Despite there are many studies on the impact of climate change on agricultural production, there is a lack of publications to address the economic impact of both climate change and variability on agricultural production in MENA region. Thus, these results are more comprehensive and more informative to policymakers than the results from field trials.

Climate change is one of the significant and threatening problems worldwide. It has attracted the attention of scientists and politicians as well as writers and critics especially in the western world. Writers have responded by writing climate change fiction despite the challenges of representation. James Bradley, an Australian novelist and critic, is one of those writers who are deeply occupied by the impacts of climate change. He has written Clade (2017) which traces the life of Adam Leith, a climatologist, and his family descendants amid the disastrous consequences of climate change. To analyze this novel, the researcher focuses on solastalgia, and applies the approach of everyday aesthetics. In a nutshell, the paper attempts to highlight the impact of climate change, examine the relationship between the characters and their environment, and explore the possibility of adaptation and detection of aesthetic values in an environment destroyed by climate change.
