Numerical simulation of the permafrost thawing near the city of Yakutsk during climate change up to the year 2100

In the city of Yakutsk, Numerical simulation of the thermal state of permafrost soils is carried out. Using climatic data from the general circulation model GFDL CM2. 1, a 1D Stefan problem is solved. profiles of the permafrost top edge, as well as moderate and intense climate warming scenarios up to the year 2100 can be obtained on the website.

Farmers adapt to climate change irrespective of stated belief in climate change: a California case study

Climate change in northern California, as in other regions of the world, is affecting natural resource-dependent communities by exacerbating droughts, heatwaves, and wildfires. Farmers recognize and describe climate shifts that match the meteorological evidence of anthropogenic climate change, but attribute these changes to weather cycles and harsh geographies, according to my findings. However, farmers continue to practice climate change with mitigation co-benefits, in despite growing evidence that climate change belief and action are not closely linked.

Local Perceptions of Climate Change Impacts in St. Kitts (Caribbean Sea) and Malé, Maldives (Indian Ocean)

Despite this, climate change studies remain at regional or national levels. In two SIDS case studies: St. Kitts in the Caribbean Sea and Maldives' Maldives, this study investigates climate change and related environmental and socioeconomic changes. This article explores human responses to this disconnect. Community shifts are evident in both island case and case studies, according to our findings, communities believe environmental changes are occurring that warrant discussion with the social transitions of daily life. Both research indicate that perceived climate change impacts are only part of the equation, as social and economic effects show two case studies of shifting island societies. Although the geographical context in each case study differs, this report explores the perceived effects of climate change and social transformations on a local level, giving valuable insight and angles for creating policies and actions to cope with the slew of socioeconomic and environmental factors impacting SIDS.

Process informed selection of climate models for climate change impact assessment in the Western Coast of India

With downscaling, the present study suggests a multi-stage process for selecting general circulation models, which forms the basis for a regional-scale climate change impact assessment with downscaling. In the first stage, the procedure evaluates the representation of climatic processes within the GCMs, assuming that an enhanced process representation in the models would ensure improved forecasts of future climate. The ability of the GCMs to simulate historical regional climate variables is investigated in the second stage. The climate models' characteristics are compared to the observed climatic variables in terms of temporal and spatial similarity. The final stage of removing interdependent models based on the mutual information measure established between the best performing climate models will be removed. The complete set of GCMs is also evaluated for the near future period 2021-2030, and the selection procedure reduces the width of the precipitation simulation band from 428 mm to 184 mm for the final chosen set. These climate projections must be downscaled before they can be used in a climate change impact assessment, which would further reduce the data's uncertainty. The climate models that weren't chosen will have their own capabilities in other areas that were not included in the previous report. Based on the purpose of the impact analysis report, the climate model selection criteria for climate model selection must be determined.

The existential risk space of climate change

Climate change is widely recognized as a major threat to human life and natural ecosystems, but the extreme risk, i. e. , where risks become existential, is poorly articulated, defined, and analyzed in the scientific literature. In the Intergovernmental Panel on Climate Change's reports, we first examine the context of existential risks and climate change, drawing on analysis in fields of global catastrophe risks and climate change, as well as key risks and the so-called Reasons for Concern. In addition, we discuss how existential risks are portrayed in the civil society climate movement, as well as what can be learned from the COVID-19 tragedy in this regard. We can better reflect existential risks in the context of climate change, and we suggest that they be classified as those threats that endanger the existence of a subject, whether that individual, a group, or nation state or humanity.
