The (n, m, l, t, r)-Wizard of houses is a game played by n players p1, p2, p3, ..., pn on a board with m houses. There are l colors of token, and t tokens for each color. Each player chooses one color from the l colors, so that each has a different color. Player p1 starts the game by choosing one token of any color and putting it into any house. Players p2, p3, p4, ..., pn follow suit, until one round is completed. The game is over when the rth round ends or after the tokens are all played, whichever comes first. In each house, each player who has the highest number of his own colored tokens receives one point. The winner is the player who has the highest score. In this paper, we determine the (2, m, 2, ∞, r)-Wizard of houses. We provide non-losing strategies for both players.

Climate change poses significant threats to ecosystems, human health, and global stability. Despite international efforts to reduce greenhouse gas emissions, the Earth's climate continues to warm, leading to extreme weather events, rising sea levels, and other detrimental impacts. In response to this crisis, scientists have begun exploring various strategies to mitigate climate change through geoengineering, which involves deliberate interventions in the Earth's climate system. This article provides an overview of climate geoengineering research, focusing on key techniques, challenges, and ethical considerations, including actions being taken by the American Geophysical Union (AGU), a nonprofit professional scientific society, to develop an ethical framework to help guide research in this important area. AGU also is driving global engagement on this topic, including with leaders and members of faith communities.

The apocalyptic framework has become a handy metaphor for climate change because this story, better than most others, is able to express the scope and severity of the transformation most scientists believe is coming to humanity's planetary and social systems. Since the first Earth Day in 1970 (Bailey 2000) and increasingly in journalistic media, nongovernmental organization circles, scientific literature, academia, eco-activism, and youth culture, climate change is referred to in world-ending terms that are explicitly apocalyptic. Those who use the phrase \"climate apocalypse\" mean to spur serious confrontation with the facts of climate change, resulting in climate activism, whether in the form of climate change mitigation or shoring up societal resiliency. However, stories not only describe reality, they help shape reality, and \"climate apocalypse\" has the unintended effect of creating passivity, fear, paralysis, and naïve hope in its audience.

The objective of this work is to determine the effects of climate change on the water needs of crops in the Bounamoussa perimeter, which is one of the large irrigation systems in the North-East of Algeria in order to predict a diagnosis of its operation. This region covers an area of 16,500 ha and is specialized in vegetable production. The climatic trend of recent years in the study area is characterized by increasingly severe drought conditions that have compromised agricultural production at this perimeter. In this study, the results of the climatic parameters projected to 2050 and 2080 under the Climate Wizard program were used in the CropWat 8.0 program for estimating the future water requirements of crops, taking into account the three Scenarios (B1, A1B, A2) of greenhouse gases (GHGs). The Decision Support System for Agrotechnology Transfer (DSSAT) 4.5 program has also been used to generate future climatic parameters (temperatures and rains) to be compared with those of the climate wizard. The results obtained in 2050 and 2080 show a trend towards increasing temperatures and a fall in rainfall for all models and that the water requirements will be multiplied by 3 to 5 times the current needs. This situation will cause an imbalance in the operation of perimeter irrigation systems. Among the measures of adaptation to this situation in the first place is the change of the date of planting after calibration of the two models for all the cultures of the perimeter.
