Are there differences between adolescent men and women in terms of knowledge about climate change? How do adolescents perceive the climate crisis depending on their gender? In order to answer these questions, we carried out a meta-analysis on a sample of 84 international papers selected by conducting a systematic review methodology. To achieve that aim, we identified studies that showed differences according to the gender variable in terms of knowledge, perceptions, and/or opinions among adolescents pursuing secondary education. A total of 26 out of 84 papers (30.95%)"concentrated between 1993 and 2017"addressed gender differences regarding climate change. The meta-analysis revealed that women score lower than men on knowledge about climate change, with the difference increasing as they move forward in their respective secondary education courses. However, women are found to attribute greater risk to the climate crisis, they are more concerned about the problem, and "unlike men, who have a more technical worldview"they show greater ecocentric willingness to accept measures to address it.

Ten years after the creation of the National System of Response to Climate Change (snrcc for its acronym in Spanish) in Uruguay, this paper examines the perceptions among local actors about the impacts of climate change on the Northeast region of the country (Departments of Rivera, Tacuarembó and Cerro Largo). It also analyzes their visions about policies and mechanisms of climate governance defined at the national level, focusing some aspects such as articulation and participation. This way the paper aims to generate relevant inputs for the discussion about the design of policies for mitigation and adaptation to this phenomenon in the specific territory considered here.

In this paper was calculated the return period of coastal floods for each of the coastal settlements that report this extreme event in the Cuban archipelago, based on the period 1901-2020. The chronology and classification of coastal floods for each province was used, as well as the Poisson distribution and the χ² goodness of fit test. It is concluded that the Poisson distribution was suitable in all cases for the significance level of 5%; while the greatest hazard is presented by Havana, Baracoa and the settlements of the Gulf of Batabanó in which the occurrence of a flood event is expected at least once every three to five years.

The present paper analyzes the main more indexed divergent elements among three of the integrated assessment models in the literature about climate change: the RICE (Regional Dynamic Integrated model of Climate and the Economy), the FUND (Climate Framework for Uncertainty, Negotiation and Distribution) and the PAGE (Policy Analysis of the Greenhouse Effect). The research shows how each one of them approaches core topics of the integrated assessment of the climate change (the adaptation, the impacts, the uncertainty, the extreme events and discontinuities) from different edges and points of view, arriving to a heterogeneity in the results.

The current global climate conditions differ from the historical average data. In the Arid Chaco this trend is reflected in the advance of the agricultural frontier towards the east of the subregion, due partially to an increase in the precipitation. The aim of this paper is to analyze temporal changes of temperature and precipitation, and the ENSO influence over these variables. The historical series of the Arid Chaco climate were analyzed for six locations for the period 1931-2011. The results show positive trends in precipitation and average temperatures, although increasingly variable. Precipitations and temperature are inversely related, possibly as a result of the advance of cold fronts from the south, causing precipitation. Nevertheless, the linear regressions between both variables do not fit significantly (p<0,05). Changes in the location of high and low pressure centers in the subregion explain another part of the variation in mean annual temperatures and precipitation. Many of the observed climate anomalies coincide with ENSO events, although the intensity of these events have little relation with the intensity of climate anomalies in the subregion.

The concept of Carbon Footprint, its origin, its relation with greenhouse gases and the methods to quantify it are presented and analyzed. The so-called greenhouse effect causes that the energy that reaches the earth at a certain rate is returned to a slower rate, increasing the temperature of the earth surface. Additionally, it is nowadays accepted that this effect is produced by some gases that are naturally emitted or produced by human actions. The Carbon Footprint is considered to be one of the most important tools for quantifying greenhouse emissions and in a general form it represents the quantity of gases emitted to the atmosphere and that is produced by human activities, and by goods and service consumption. Since there is no consensus about the definition of Carbon Footprint or the forms of quantifying it, this first part of the paper series analyzes the main concept and the main present views on the Carbon Footprint.

The aim of this paper is to explore alternative institutional ways to approach the public strategies for the attention of the meteorological events that occur frequently in Mexico. In the context of a growing presence of such events in the country associated with climate change, increased resilience relates to the identification and correction of the vulnerability of those areas susceptible to such threats.

Climate variability (CV) and climate change (CC) have been associated to global changes or to changes in the climate regime and have shown remarkable effects on the hydrological cycle. Water shortage, changes in precipitation intensity, and variability of extreme events are gaining more importance. Because of the increase in air temperature and the changes in precipitation, CC is increasing the competition for fresh water and is impacting hydrological processes and regimes, causing in some cases a larger flow of pollutants and sediments in lakes and rivers, water quality degradation, alteration of the rate of bio-geochemical processes, and reduction of dissolved oxygen concentration. The need for adapting to CC is urgent when large economic and social changes are occurring that affect usage of water resources (WR). CC is increasing the vulnerability of badly-managed water systems, creating an urgent need to build a new framework for the management of WR. In this paper, an integrated water resource management concept (IWRM) is presented, which is gaining acceptance as a CC adaptation strategy. [ABSTRACT FROM AUTHOR]

Last August, the IPCC (Intergovernmental Panel on Climate Change) celebrated its 20th anniversary. Since the Second Assessment Report, the IPCC is currently focusing on the potential effects of climate on health. However, the diseases related to climate, beyond the victims of the so-called natural disasters are increasing all over the world. This paper presents a brief overview on the reports and the overall picture of the current situation. [ABSTRACT FROM AUTHOR]
