«If
global emissions of carbon dioxide continue to rise at the rate of the past decade,» said Dr. Hansen, «this research shows that there will be disastrous effects, including increasingly rapid sea level rise, increased frequency of droughts and floods, and increased stress on wildlife and plants due to rapidly shifting climate zones.»
Lead author James Hansen, NASA Goddard Institute for Space Studies, New York, concludes: «If
global emissions of carbon dioxide continue to rise at the rate of the past decade, this research shows that there will be disastrous effects, including increasingly rapid sea level rise, increased frequency of droughts and floods, and increased stress on wildlife and plants due to rapidly shifting climate zones.»
Not exact matches
The ability
of the oceans to take up
carbon dioxide can not keep up with the rising levels
of greenhouse gases in the atmosphere, which means
carbon dioxide and
global temperatures will
continue to increase unless humans cut their
carbon dioxide emissions.
«If ozone
continues to increase, vegetation will take up less and less
of our
carbon dioxide emissions, which will leave more CO2 in the atmosphere, adding to
global warming,» Sitch says.
Meanwhile,
global emissions of carbon dioxide and other greenhouse gases
continue to increase, promising far worse to come.
* Scientists from the Carnegie Institution's Department
of Global Ecology have calculated that if current
carbon dioxide emission trends
continue, by mid-century 98 %
of present - day reef habitats will be bathed in water too acidic for reef growth.
Hence, the rate
of global carbon dioxide emissions continues to accelerate.
Now Raupach and colleagues plan to look at the relationship
of emissions to the
global carbon dioxide budget, and at
continued increases in
emissions as a source
of Earth system vulnerability.
They have told the public, politicians, and the press that «
global warming» (alias «climate change») is primarily due to human - caused
emissions of carbon dioxide, and that if this
continues at current levels that this will result in catastrophic
global warming.
These trends lead to
continued growth in
global energy - related
emissions of carbon -
dioxide (CO2), from 27 Gt in 2005 to 42 Gt in 2030 — a rise
of 57 %.
First, substantial
global warming is already «baked in,» as a result
of past
emissions and because even with a strong climate - change policy the amount
of carbon dioxide in the atmosphere is most likely to
continue rising for many years.
Global carbon dioxide emissions continue to track the high end of a range of emission scenarios, expanding the gap between current emission trends and the emission pathway required to keep the global - average temperature increase below 2 degrees Ce
Global carbon dioxide emissions continue to track the high end
of a range
of emission scenarios, expanding the gap between current
emission trends and the
emission pathway required to keep the
global - average temperature increase below 2 degrees Ce
global - average temperature increase below 2 degrees Celsius.
That means if plants around the world
continue to adjust to rising
carbon dioxide concentrations, increasing their biomass on a
global scale, they could actually help offset some
of our human
carbon emissions by removing more
carbon dioxide from the air.
