We estimate a 7% rise in wetland CH4 emissions over 2003–2007, due to warming of mid-latitude and Arctic wetland regions, which we find is consistent with recent changes in atmospheric CH4.

This report highlights the profound impact that the ozone hole has had on the
Antarctic environment over the last 30 years, shielding the continent from
much of the effect of global warming. However, this situation will not last.
Over the next century we expect ozone concentrations above the Antarctic to
recover, but if greenhouse gas concentrations increase at the present rate then
temperatures across the continent will increase by several degrees and there
will be about one third less sea ice.

Using gravity measurement data from the NASA/German Aerospace Center's Gravity Recovery and Climate Experiment (Grace) mission, a team of scientists found that the East Antarctic ice sheet may have begun to lose ice.

our model indicates that the impact of twentieth-century warming on sea level will continue for many centuries into the future
As global temperatures increase, the potential for longer growing seasons to
enhance the terrestrial carbon sink has been proposed as a mechanism to reduce
the rate of further warming. At the Niwot Ridge AmeriFlux site, a subalpine
forest in the Colorado Rocky Mountains, we used a 9-year record (1999–2007) of
continuous eddy flux observations to show that longer growing season length
(GSL) actually resulted in less annual CO2 uptake.

computer modeling of the cooling suggests that the cooling was caused by a reduction of greenhouse gases in the atmosphere

The new data continues the global trend in accelerated ice loss over the past few decades

Any increase in dead zones from global warming will last for thousands of years. They will be a permanent fixture ... In the worst-case scenario, dead zones could encompass more than a fifth of the world's oceans
article
climate change that takes place due to increases in carbon dioxide concentration is largely irreversible for 1,000 years after emissions stop
study
all our simulations have a very small probability of warming less than 2.4°C, the lower bound of the IPCC AR4 projected likely range
study
Greenhouse gases play an important role in North American climate ... More than half of this warming is likely the result of human-caused greenhouse gas forcing of climate change

The rate of warming we are seeing is unprecedented in human history.
article
None of the natural processes can account for the overall warming trend in global surface temperatures ... solar forcing contributed negligible long-term warming in the past 25 years and 10% of the warming in the past 100 years
study
Avoiding environmental damage from ocean acidification requires reductions in
carbon dioxide emissions regardless of climate change.
