Resumen
El cambio climático aumentará significativamente los casos de malaria y las muertes en África para 2050, principalmente debido a eventos climáticos extremos. El desarrollo urgente de estrategias de control de la malaria resistentes al clima es crucial para los esfuerzos de erradicación.
Área de la Ciencia:
- Ciencias ambientales Ciencias ambientales.
- Epidemiología La epidemiología.
- Ciencias del clima Ciencias del clima Ciencias del clima Ciencias del clima
Sus antecedentes:
- Los impactos del cambio climático en la erradicación de la malaria no se comprenden completamente.
- Los estudios anteriores a menudo aíslan los factores ecológicos, descuidando las interacciones socioeconómicas y climáticas extremas.
Objetivo del estudio:
- Para estimar el impacto futuro del cambio climático en la carga de la malaria en África.
- Identificar los principales impulsores del aumento del riesgo de malaria, considerando tanto los efectos ecológicos como los perjudiciales.
Principales métodos:
- Integró 25 años de datos africanos sobre el clima, la malaria, los factores socioeconómicos y el clima extremo.
- Utilizó un modelo geotemporal con proyecciones climáticas bajo el escenario SSP2-4.5.
Principales resultados:
- Se proyectaron 123 millones de casos adicionales de malaria y 532.000 muertes adicionales en África (2024-2050).
- Los fenómenos meteorológicos extremos son el principal factor, responsables del 79% de los casos y del 93% de las muertes.
- El aumento de la carga de la malaria se debe principalmente a la intensificación en las áreas endémicas, no a la expansión de la gama.
Conclusiones:
- El cambio climático representa una amenaza sustancial para los esfuerzos de erradicación de la malaria en África.
- Se necesitan con urgencia sistemas de control de la malaria y de respuesta a emergencias que sean resistentes al clima.
- Abordar los impactos climáticos extremos es fundamental para las futuras estrategias de control de la malaria.

01:50Global Climate Change
28.9K
Throughout its ~4.5 billion year history, the Earth has experienced periods of warming and cooling. However, the current drastic increase in global temperatures is well outside of the Earth’s cyclic norms, and evidence for human-caused global climate change is compelling. Paleoclimatology, the study of ancient climate conditions, provides ample evidence for human-caused global climate change by comparing recent conditions with those in the past.

01:16What is Climate?
20.8K
Climate refers to the prevailing weather conditions in a specific area over an extended period. As the saying goes, “Climate is what you expect. Weather is what you get.” Climate is influenced by geographic factors, such as latitude, terrain, and proximity to bodies of water.

Learning to draw Fischer projections of molecules and understanding their relevance plays a crucial role in the visual depiction of organic molecules. A Fischer projection is a two-dimensional projection on a planar surface to simplify the three-dimensional wedge–dash representation of molecules. This is especially helpful in the case of molecules with multiple chiral centers that can be difficult to draw. Here, all the bonds of interest are represented as horizontal or vertical lines. While...

Different notations are used to represent the three-dimensional structure of molecules on two-dimensional surfaces. One of the most commonly used representations is the dash-wedge formula. The dashed wedges, solid wedges, and the plane lines indicate the groups situated behind the plane, coming out of the plane, and in the plane, respectively.

Social psychologists analyze how groups influence one another, shaping social structures and interactions through both cooperation and competition. These dynamics manifest in various ways, ranging from economic partnerships to intergroup conflicts that shape societal structures and perceptions.Cooperation and Competition in Intergroup RelationsIntergroup relationships vary across contexts, sometimes fostering cooperation and mutual benefit while at other times leading to conflict and...

Coordinates and map projections are essential tools in accurately representing the Earth's surface for various applications, ranging from navigation to spatial analysis. The latitude and longitude coordinate system is a universally recognized framework for defining locations. Latitude specifies the distance of a point north or south of the equator, measured in degrees from 0° at the equator to 90° at the poles. Longitude indicates a location's position east or west of the prime meridian,...
