Open Letter by Netherlands Scientists on IPCC and Errors in 2007 Climate Change Report

Green Car Congress

In response to the ongoing discussion about the reliability of the UN IPCC and the climate reports, a group of 55 leading Dutch scientists working in the field of climate change, energy and the environment wrote an open letter. Errors in the IPCC climate change report are being seized by some to discredit climate science.

Perspective: The Role of Offsets in Climate Change Legislation

Green Car Congress

For example, a covered source (an entity in the power generation, chemicals, steel, and cement industries) can make reductions beyond its compliance obligations and then sell these reductions as credits to other covered sources. Nitrous oxide (N 2 O) emissions from agricultural operations or specific industrial processes (GWP = 298).

EPA says methane emissions from natural gas production have dropped 36% from 2007-2011

Green Car Congress

In its recently released Inventory of US Greenhouse Gas Emissions and Sinks: 1990 – 2011 ( earlier post ), the US Environmental Protection Agency (EPA) reported that methane (CH 4 ) emissions from the field production of natural gas have declined by 36% from 2007 to 2011 (from 83.1 Climate Change Emissions Natural Gas'

Black carbon is a much larger cause of climate change than previously assessed; about twice previous estimates, and 2/3 the effect of CO2

Green Car Congress

These effects are calculated with climate models, but when possible, they are evaluated with both microphysical measurements and field observations. Predominant sources are combustion related; namely, fossil fuels for transportation, solid fuels for industrial and residential uses, and open burning of biomass.
