Sentences with phrase «human caused climate change contribution»

Not exact matches

As the graph below from Spracklen's News and Views article shows, the balance between warming (red shading) and cooling (blue shading) have kept the country's contribution to human - caused climate change pegged at about 10 % in recent decades, despite soaring fossil fuel emissions.
Scientifically, the meteorologists, climatologists, and atmospheric physicists, who were responsible for «discovering» the human contribution to the terrestrial greenhouse effect, have been the most consistent champions of its importance, while the solar physics community, and especially those interested in solar - terrestrial relations, have increasingly stressed the possible importance of the long - term variations of the solar constant as the chief cause of climate change.
Nevertheless, it should be stated that since CO2 is a GH, and since most if not all of its increase is human - caused, there must be some minor human contribution to climate change.
While I reject most apocalyptic scenarios as unfounded or unduly speculative, I am convinced that the human contribution to climate change will cause or exacerbate significant problems in at least some parts of the world.
We not only agree, but have dozens of examples of how great American bird conservation projects make considerable, sometimes unexpected contributions to other important causes including amphibian conservation, human health, food safety, climate change, water conservation, and home energy savings.
While it is generally accepted that the observed reduction of the Northern Hemisphere spring snow cover extent (SCE) is linked to warming of the climate system caused by human induced greenhouse gas emissions, it has been difficult to robustly quantify the anthropogenic contribution to the observed change.
Some are specific about quantifying the percentage of human contribution, others just say «humans are causing climate change» without specific quantification.
E.g., research assumes greenhouse gas emissions cause warming without explicitly stating humans are the cause»... carbon sequestration in soil is important for mitigating global climate change» (4a) No position Does not address or mention the cause of global warming (4b) Uncertain Expresses position that human's role on recent global warming is uncertain / undefined «While the extent of human - induced global warming is inconclusive...» (5) Implicit rejection Implies humans have had a minimal impact on global warming without saying so explicitly E.g., proposing a natural mechanism is the main cause of global warming»... anywhere from a major portion to all of the warming of the 20th century could plausibly result from natural causes according to these results» (6) Explicit rejection without quantification Explicitly minimizes or rejects that humans are causing global warming»... the global temperature record provides little support for the catastrophic view of the greenhouse effect» (7) Explicit rejection with quantification Explicitly states that humans are causing less than half of global warming «The human contribution to the CO2 content in the atmosphere and the increase in temperature is negligible in comparison with other sources of carbon dioxide emission»»
(Geoengineering is popular among right - leaning think tanks; as are the views — which Thernstrom does not share — that climate change isn't caused by human activities, or that our contribution is overhyped and may not be the primary cause.)
Therefore, knowledge on the Time of Emergence (ToE), or the years that the human contributions to climate change will become more important than natural variability in causing heat waves, is crucial for better mitigation and adaptation efforts.
