While the world is looking for sharp reductions in greenhouse gases responsible for climate change, growing global meat production is going to severely compromise future efforts... a study from the University of Chicago showed that if Americans were to reduce meat consumption by 20 percent it would be as if they switched from a standard sedan to the ultra-efficient Prius.»

First, while the early 20th century warming was likely predominantly naturally - caused (i.e. low volcanic activity and increasing solar activity), there was also a significant human contribution as greenhouse gas emissions began to ramp up.

While environmental activists and some politicians claim «the debate is over» and call for immediate action to reduce man - made greenhouse gas emissions, others say the science points to only a very small human impact — too small to warrant concern — and the costs of trying to prevent global warming far exceed the benefits.

Objection: There was global cooling in the»40s,»50s, and»60s, even while human greenhouse - gas emissions were rising.

«Climate science» as it is used by warmists implies adherence to a set of beliefs: (1) Increasing greenhouse gas concentrations will warm the Earth's surface and atmosphere; (2) Human production of CO2 is producing significant increases in CO2 concentration; (3) The rate of rise of temperature in the 20th and 21st centuries is unprecedented compared to the rates of change of temperature in the previous two millennia and this can only be due to rising greenhouse gas concentrations; (4) The climate of the 19th century was ideal and may be taken as a standard to compare against any current climate; (5) global climate models, while still not perfect, are good enough to indicate that continued use of fossil fuels at projected rates in the 21st century will cause the CO2 concentration to rise to a high level by 2100 (possibly 700 to 900 ppm); (6) The global average temperature under this condition will rise more than 3 °C from the late 19th century ideal; (7) The negative impact on humanity of such a rise will be enormous; (8) The only alternative to such a disaster is to immediately and sharply reduce CO2 emissions (reducing emissions in 2050 by 80 % compared to today's rate) and continue further reductions after 2050; (9) Even with such draconian CO2 reductions, the CO2 concentration is likely to reach at least 450 to 500 ppm by 2100 resulting in significant damage to humanity; (10) Such reductions in CO2 emissions are technically feasible and economically affordable while providing adequate energy to a growing world population that is increasingly industrializing.

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.

While the GCC distributed a «backgrounder» to politicians and media in the early 1990s claiming «The role of greenhouse gases in climate change is not well understood,» a 1995 GCC internal memo drafted by Mobil Oil (which merged with Exxon in 1998) stated that: «The scientific basis for the Greenhouse Effect and the potential impact of human emissions of greenhouse gases such as CO2 on climate is well established and can not be denigreenhouse gases in climate change is not well understood,» a 1995 GCC internal memo drafted by Mobil Oil (which merged with Exxon in 1998) stated that: «The scientific basis for the Greenhouse Effect and the potential impact of human emissions of greenhouse gases such as CO2 on climate is well established and can not be deniGreenhouse Effect and the potential impact of human emissions of greenhouse gases such as CO2 on climate is well established and can not be denigreenhouse gases such as CO2 on climate is well established and can not be denied.»

Humans are developing technologies and means to improve lives while reducing environmental impacts even as humanity is increasing greenhouse gas emissions and worsening climate catastrophe risks and impacts.

While you acknowledged that the climate is changing and that humans are having an impact on it, it is critically important that you understand that emissions of carbon dioxide and other greenhouse gases are the primary cause.

People will die», while others scream how moves to cut greenhouse gas emissions «devalues human life» and «kills thousands» in Britain.

To identify the effects of human activity on temperature, we simulate the model (estimation sample 1960 — 1998) with post 1998 values of solar insolation, SOI, and volcanic sulfates held at their 1998 level while allowing greenhouse gas concentrations and sulfur emissions to evolve as observed.

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»»

While I believe the evidence supports human - caused global warming, I don't think the world has the collective will to voluntarily reign in greenhouse gas emissions.

While the SE4All objectives do not explicitly address climate change, it is clear that sustainable energy is a prerequisite for reducing greenhouse gas emissions: 80 % of human carbon dioxide emissions come from the global energy system, including transportation, buildings, industry, and electricity, heat, and fuel production.
