Summary
[edit]DescriptionGreenhouse-gas-emission-scenarios-01.png |
English: What does the future of our carbon dioxide and greenhouse gas emissions look like. In the visualization we show a range of potential future scenarios of global greenhouse gas emissions (measured in gigatonnes of carbon dioxide equivalents), based on data from Climate Action Tracker. Interactive data of these pathways can be found here. Here, five scenarios are shown:
No climate policies: projected future emissions if no climate policies were implemented; this would result in an estimated 4.1-4.8°C warming by 2100 (relative to pre-industrial temperatures) Current climate policies: projected warming of 3.1-3.7°C by 2100 based on current implemented climate policies National pledges: if all countries achieve their current targets/pledges set within the Paris climate agreement, it’s estimated average warming by 2100 will be 2.6-3.2°C. This will go well beyond the overall target of the Paris Agreement to keep warming “well below 2°C”. 2°C consistent: there are a range of emissions pathways that would be compatible with limiting average warming to 2°C by 2100. This would require a significant increase in ambition of the current pledges within the Paris Agreement. 1.5°C consistent: there are a range of emissions pathways that would be compatible with limiting average warming to 1.5°C by 2100. However, all would require a very urgent and rapid reduction in global greenhouse gas emissions. Español: ¿Cómo es el futuro de nuestras emisiones de dióxido de carbono y gases de efecto invernadero? En la visualización, mostramos una gama de posibles escenarios futuros de emisiones globales de gases de efecto invernadero (medidos en gigatoneladas de dióxido de carbono equivalente), basados en datos de Climate Action Tracker. Aquí, se muestran cinco escenarios: Sin políticas climáticas: emisiones futuras proyectadas si no se implementaran políticas climáticas; esto resultaría en un calentamiento estimado de 4.1-4.8°C para 2100 (en relación con las temperaturas preindustriales) Políticas climáticas actuales: calentamiento proyectado de 3.1-3.7°C para 2100 basado en las políticas climáticas implementadas actualmente. Compromisos nacionales: si todos los países logran sus objetivos / compromisos actuales establecidos en el acuerdo climático de París, se estima que el calentamiento promedio para 2100 será de 2.6-3.2 ° C. Esto irá mucho más allá del objetivo general del Acuerdo de París de mantener el calentamiento “muy por debajo de los 2°C”. 2°C consistente: hay una gama de vías de emisiones que serían compatibles con limitar el calentamiento promedio a 2°C para 2100. Esto requeriría un aumento significativo en la ambición de los compromisos actuales dentro del Acuerdo de París. 1,5°C consistente: hay una gama de vías de emisión que serían compatibles con limitar el calentamiento promedio a 1,5°C para 2100. Sin embargo, requeriría una reducción urgente y rápida de las emisiones globales de gases de efecto invernadero. |
