Sentences with phrase «significant planetary changes»

Not exact matches

The key points of the paper are that: i) model simulations with 20th century forcings are able to match the surface air temperature record, ii) they also match the measured changes of ocean heat content over the last decade, iii) the implied planetary imbalance (the amount of excess energy the Earth is currently absorbing) which is roughly equal to the ocean heat uptake, is significant and growing, and iv) this implies both that there is significant heating «in the pipeline», and that there is an important lag in the climate's full response to changes in the forcing.
However, even a smaller figure (I had calculated about 0.17 W / m ^ 2 based on your inflated figure for total planetary albedo, but you can check it out) is still significant when compared with the total flux imbalance, which I think is a more informative comparison than an arbitrarily selected change in cloud cover, because it compares the sea ice reduction with the effects of all climate variations that have been operating in recent years..
In combination, these two research efforts add to the massive amount of scientific evidence that climate change is always occurring; and, most definitely does not require human consumer / industrial greenhouse gases to produce significant impacts on planetary environments and those associated civilizations.
Humans have been changing Earth's landscapes at globally significant levels for at least 3000 years, and doing so by increasingly productive and efficient means, according to our new research challenging the claim that use of land by industrial civilization is destroying planetary ecology at an accelerating pace.
