These claims were subsequently disputed in an article in Eos (Rahmstorf et al, 2004) by an international team of scientists and geologists (including some of us here at RealClimate), who suggested that Shaviv and Veizer's analyses were based on unreliable and poorly replicated estimates, selective adjustments of the data (shifting the data, in one case by 40 million years) and drew untenable conclusions, particularly with regard to the influence of anthropogenic greenhouse gas concentrations on recent warming (see for example the exchange between the two sets of authors).

They challenge the longstanding view of Richard Lindzen and others that there are natural regulators built in to the tropical climate system that «let off steam» in a way; but they also challenge those using the specter of tropical warming — including the Amazon rain forest turning into a desert — as another reason to move swiftly to curb greenhouse gases.

Taking account of their historic responsibility, as well as the need to secure climate justice for the world's poorest and most vulnerable communities, developed countries must commit to legally binding and ambitious emission reduction targets consistent with limiting global average surface warming to well below 1.5 degrees Celsius above preindustrial levels and long - term stabilization of atmospheric greenhouse gas concentrations at well below below 350 p.p.m., and that to achieve this the agreement at COP15 U.N.F.C.C.C. should include a goal of peaking global emissions by 2015 with a sharp decline thereafter towards a global reduction of 85 percent by 2050,

What is obvious is that including the data of the past few years pushes the estimates of climate sensitivity downward, because there was little warming over the past decade despite a larger greenhouse gas forcing.

For instance, the warming that began in the early 20th century (1925 - 1944) is consistent with natural variability of the climate system (including a generalized lack of significant volcanic activity, which has a cooling effect), solar forcing, and initial forcing from greenhouse gases.

In regards to your statements about CO2, the fact that CO2 is a greenhouse gas, and that increasing CO2 will produce warming, is accepted by virtually every scientist, including most of the AGW skeptics (Christy, Spencer, Lindzen...).

• Greenhouse gases contributed a global mean surface warming likely to be in the range of 0.5 °C to 1.3 °C over the period 1951 to 2010, with the contributions from other anthropogenic forcings, including the cooling effect of aerosols, likely to be in the range of − 0.6 °C to 0.1 °C.

They have survived previous Arctic warming periods, including the last warm stretch between ice ages some 130,000 years ago, but some climate experts project that nothing in the species» history is likely to match the pace and extent of warming and ice retreats projected in this century and beyond, should emissions of heat - trapping gases continue unabated.

However, taking account of sampling uncertainty (as most more recent detection and attribution studies do, including those shown in Figure 9.9) makes relatively little difference to estimates of attributable warming rates, particularly those due to greenhouse gases; the largest differences occur in estimates of upper bounds for small signals, such as the response to solar forcing (Allen and Stott, 2003; Stott et al., 2003a).

In the Arctic, the tipping points identified in the new report, published on Friday, include: growth in vegetation on tundra, which replaces reflective snow and ice with darker vegetation, thus absorbing more heat; higher releases of methane, a potent greenhouse gas, from the tundra as it warms; shifts in snow distribution that warm the ocean, resulting in altered climate patterns as far away as Asia, where the monsoon could be effected; and the collapse of some key Arctic fisheries, with knock - on effects on ocean ecosystems around the globe.»

Moreover, it also includes a number of detection and attribution studies, the IPCC's «gold standard» in terms of inferring climate change and establishing consistency of AO - GCM simulations of greenhouse gas induced warming with observations.

For example, short - lived greenhouse gases, such as methane, are not included in — nor necessarily appropriate for4 — the 1 trillion tonne C budget approach because they play a secondary role in influencing long - term warming.

If the body of evidence is so strong and the concensus so overwhelming, why is it that no organisation, including IPCC, will directly answer the question «what percentage of forecast global warming is due to greenhouse gas emissions».

Greenhouse gases contributed a global mean surface warming likely to be in the range of 0.5 °C to 1.3 °C over the period 1951 − 2010, with the contributions from other anthropogenic forcings, including the cooling effect of aerosols, likely to be in the range of − 0.6 °C to 0.1 °C.
