“CO2 is certainly a heat-trapping greenhouse gas, but hardly the primary one: Water vapor accounts for about 95 percent of greenhouse gases.
The world's most important greenhouse gas is carbon dioxide, a by-product of the burning of fossil fuels.

As of today,JAXA shows that we have more ice than any time on this date for the past 8 years of Aqua satellite measurement for this AMSRE dataset."
However, due to various reasons,[specify] both satellites had a much shorter than expected life term.

But more than 7% of deaths are related to cold—counting hypothermia, as well as increased blood pressure and risk of heart attack that results when the body restricts blood flow in response to frigid temperatures.”
This increased pressure reduced blood flow back to the heart, thereby reducing blood flow to the body and resultign in signs and symptoms of shock.

Just 0.7% of the world’s forests are coastal mangroves, y​​​​​​et they store up to 10 times as much carbon per hectare as tropical forests.
Amazonian forests are estimated to have accumulated 0.62 ± 0.37 tons of carbon per hectare per year between 1975 and 1996.

94 percent of the carbon emissions which you so want to get rid of are caused by nature.
The vast majority of anthropogenic carbon dioxide emissions come from combustion of fossil fuels, principally coal, oil, and natural gas, with additional contributions coming from deforestation, changes in land use, soil erosion and agriculture (including livestock).

The Greenland ice sheet is at least 400,000 years old and warming was not global when Europeans settled in Greeland 1,000 years ago
Between 2001 and 2005: Sermeq Kujalleq broke up, losing 93 square kilometres (36 sq mi) and raised awareness worldwide of glacial response to global climate change.

The Independent Climate Change Email Review found the CRU scientists were unhelpful and unsympathetic to information requesters and at times broke FoI laws.
The e-mail theft highlighted "the harassment that denialists inflict on some climate-change researchers, often in the form of endless, time-consuming demands for information under the US and UK Freedom of Information Acts.
