全球升温1.5摄氏度会摧毁至少70%的珊瑚礁，但是如果升温2摄氏度，超过99%的珊瑚礁都会死亡。这对于依赖珊瑚觅食和栖息的鱼群是一个毁灭性打击。Warming of 2°C, versus 1.5°C, would also increase the impact on food production.全球升温由1.5摄氏度到2摄氏度还会加大对粮食生产的影响。"If you have cro...
We find that for model simulations with a symmetric 1% per year increase and decrease in atmospheric CO2, the temperature change (螖T) versus cumulative CO2emissions (CE) relationship is nonlinear during periods of net negative emissions, owing to the lagged response of the deep ocean to ...
In recent decades, there have been a number of debates on climate warming and its driving forces. Based on an extensive literature review, we suggest that (1) climate warming occurs with great uncertainty in the magnitude of the temperature increase; (2) both human activities and natural forces...
An alternate metric is the global temperature potential (GTP). Unlike the GWP, which is a measure of the heat absorbed over a given time period due to emissions of a gas, the GTP is a measure of the temperature change at the end of that time period relative to CO2. The calculation of...
CO2's Impact On Global Temperature Trends: Minimal To Non-Existent, Per IPCC's Gold-Standard Climate change, as represented by global cooling and global warming trends, is in a constant flux...the IPCC's gold-standard temperature dataset provides the empirical proof that a natural cycle of up...
It is often said that the science behind CO2 enhanced global warming is simple and settled. However, calculating the top of the atmosphere ‘radiative forcing’ of CO2 is really not that straightforward at all. First you need to assume an initial temperature profile in the atmosphere and then ...
Fig. 4: Control of temperature versus precipitation on CIA. a,bBoxplots of CIA grouped by zones of MAT (a, interval of 2 °C) and MAP (b, interval of 0.2 m/yr). The notch of each box displays the variability of the median: if the notches of both boxes do not overlap, ...
In panela, positive values mean that the NEEIAVin the latitudinal band supports the dominance of terrestrial water storage in the global NEEIAVwhile the negative values mean that the NEEIAVin the latitudinal band supports the dominance of temperature. In panelb, the solid bars are the contribut...
The role of atmospheric CO2 in regulating global temperature came under renewed scrutiny at the turn of the 21st century in respect to the climate of the Phanerozoic Eon beginning about 540 million years before present (Mybp). One group of investigators supported the prevailing consensus that ...
