aHuman activities causing global climate change are the burning of fossil fuels, which release CO2, water vapour, and SO2¬ into the atmosphere; agricultural activity, which releases CO2 from the soil; the increased use of fertilizer and animal husbandry, which adds nitrous oxide (N2O) and ...
athe increase in CO2 levels in the atmosphere as a result of human activity means that the world is already locked into some climate change, and faces a major challenge to keep global temperature rises to below two degrees. 在二氧化碳水平的增量在大气由于人类活动意味着世界已经是锁着的入一些气候...

but the public continues to be deeply divided over both its cause and what to do about it (only 47% say that human activity, such as the burning of fossil fuels, is mostly to blame for the earth
We found that the RORA motif was significantly enriched in DMRs in primates (Fig. 5d) and showed high activity in accessible-chromatin sites of ChCs in all species (Fig. 5e and Supplementary Table 14). Moreover, 60 of 357 DEGs contained an ROR-binding motif in DMRs and in regions of ...

Large, well-documented wildfires have recently generated worldwide attention, and raised concerns about the impacts of humans and climate change on wildfire regimes. However, comparatively little is known about the patterns and driving forces of global fire activity before the twentieth century. Here ...
“Habitat destruction due to human activity—such as logging, farming, and armed conflicts—is pushing giraffe populations to the breaking point throughout the African continent. An ever-expanding human population, largely unchecked due to a huge unmet need for family planning, is having a frighteni...
aIf true, this would imply that CO2 are not important influences on the natural greenhouse capacity of Earth, and that the continuing increase in CO2 due to human activity is therefore not relevant to climate change. 如果真实,这暗示二氧化碳不是对地球自然温室容量的重要影响,因此,并且在二氧化碳的继...
