Another graphic, circulated on Twitter by German broadcaster Deutsch Welle, shows how
different cumulative, historic
emissions look from the current
scenario: China three years ago surpassed the United States as the global
greenhouse gas emissions leader.
In their newly published study, the U-M researchers examined cost, energy use and
greenhouse gas emissions for
different types of 60 - watt - equivalent bulbs and created a computer model to generate multiple replacement
scenarios, which were then analyzed.
Scenarios A, B, and C are the same model, but with
different forcings (
different greenhouse gas emissions forecasts).
In recent years, they've also started to consider the impact that
different scenarios will have on attempts to limit
emissions of
greenhouse gases.
Lam and team used climate models from the Intergovernmental Panel on Climate Change to examine the economic impacts of climate change on fish stocks and fisheries revenues under two
different emissions scenarios: a high -
emission scenario, in which the rates at which
greenhouse gases are pumped into the Earth's atmosphere continue to rise unchecked, and a low -
emission scenario under which ocean warming is kept below two degrees Celsius.
Wehner and his co-authors of Chapter 2 of the NCA, which looked at the physical basis for our understanding of climate change, considered seven
different future
scenarios (including four new ones), ranging from the «do nothing» option to a geoengineering option, which would require an as - yet uninvented technology to take CO2 out of the atmosphere on a global scale, to achieve net negative
emissions of
greenhouse gases by 2050.
«and we basically don't know whether or not
different scenarios of
greenhouse gas emissions will be (or not be) the primary driver on timescales of a century or less.»
The red and magenta lines show the forcing from anthropogenic
greenhouse gases for the two
different emission scenarios.

Climate change was assessed by means of two Long Ashton Research Station - Weather Generator (LARS - WG) weather generators and all outputs from the available general circulation models in the Model for the Assessment of
Greenhouse -
gas Induced Climate Change - SCENario GENerator (MAGICC - SCENGEN) software, in combination with
different emission scenarios at the regional scale, while the Providing Regional Climates for Impacts Studies (PRECIS) model has been used for projections at the local scale.
A report by the Sussex Energy Group and Tyndall Centre for Climate Change Research entitled China's Energy Transition: Pathways for Low Carbon Development set out four
different scenarios for low - carbon development in China in an attempt to demonstrate how China's economic development can be decoupled from carbon
emissions growth — allowing its economy to expand by some 8 to 13 times while presumably stabilizing
greenhouse gas concentrations in the atmosphere.
Science writer Greg Laden wrote that the Duke study will receive «criticism from climate scientists» because it includes language that suggests it is assessing the likelihood of
different warming
scenarios by predicting the amount of
greenhouse gas emissions that will occur in the future, which it can't possibly know.
