STEADY-STATE TERRESTRIAL ECOSYSTEMS AND THE GLOBAL CARBON-CYCLE - LUGO,AE,BROWN - 《Vegetatio》 被引量: 69发表: 1986年 Contribution of increasing CO2 and climate change to the carbon cycle in China's ecosystems [1] Atmospheric CO2 and China's climate have changed greatly during 1961–2000. ...
warming, projected global temperatures are likely to exceed 2 °C above pre-industrial times for higher emission scenarios, with “likely” being defined as with a probability between 66 and 100%. This threshold can, however, likely be avoided in a low emission scenario. What are we to make...
This is known as the greenhouse effect and ultimately leads to global warming. CO2 is one of the greenhouse gases in the atmosphere. How much do we need to reduce CO2-emissions? How big reductions in CO2-emissions are needed to limit the rise in global temperatures? According to the UN ...
A more precise understanding of the contribution of human activity to potential global warming ( vis-à-vis natural climatic variability) is of critical policy interest. Surprisingly little research has been devoted to establishing the underlying statistical relationship between human activities and CO 2...
warming have the potential to inform projections. Here we show that robust across-model relationships exist between the global spatial patterns of several fundamental attributes of Earth’s top-of-atmosphere energy budget and the magnitude of projected global warming. When we constrain the model ...
5b). Increasing [CO2] not only adds to global warming but also allows greater photosynthesis. Under RCPs 6.0 and 8.5, assimilation rates are projected to increase steadily throughout the twenty-first century, but under RCP 2.6, they are expected to increase only to about 2040 before returning ...
There are many benefits to low-carbon life, such as: energy conservation, reduce co2 emissions and prevent global warming, air pollution. These effects are improving the environment and improve the quality of life made a great contribution. ...
However, recent studies have challenged the carbon neutrality hypothesis by introducing metric indicators to assess the global warming potential of biogenic CO2 (GWPbio). In this study we calculated the GWPbio factors using a forest growth model and radiative forcing effects with a time horizon of ...
3 Comparing the net CO2-emissions of the four scenarios for the global plastic sector. These emission lines are the same as the solid net emission lines of Fig. 3; biogenic emissions are assumed to be renewable and therefore have no net contribution to climate change. Extended Data Fig. 4 ...
