The announcement by NIWA that last month was one of the coldest Decembers in the last 60 years is evidence that there is no “global warming” in New Zealand, according to the New Zealand Climate Science Coalition.

The first image was taken from NIWA's website. The extreme warming spike around 1998 was the result of the El Nino southern oscillation, a natural climate event. Shortly after the NZCSC drew attention to this graph in May 2006, it was removed from the NIWA website and replaced by the Second image, including the new black dotted trend line 1900-2005 which emphasises for readers the steeper warming at about 1 degree for this particular 106 year period. It is clear to the eye that the entire 1853 to 2005 period shows a total net ‘warming’ of less than three-quarters of 1 degree warming over the 153 years.

Several records for temperatures in Britain have been broken during 2006.
Scientists from the Met Office and the University of East Anglia (UEA) say the year was probably the hottest in central England since records began.
The average growing season temperature was the highest recorded in central England, while previous maximums for individual months were also passed.
Globally, 2006 was the sixth hottest year on record, cooled by La Nina conditions in the Pacific Ocean.
The top 10 warmest years recorded globally have all occurred during the last 12 years.

Current sea level rise projections could be under-estimating the impact of human-induced climate change on the world's oceans, scientists suggest.
By plotting global mean surface temperatures against sea level rise, the team found that levels could rise by 59% more than current forecasts.
The researchers say the possibility of greater increases needs be taken into account when planning coastal defences.
The findings have been published in the online edition of the journal Science.

Africa has experienced a significant drying in the past three years, new satellite data reveals.
The volume of water lost from the land amounts to 334 cubic km, which is almost as much as all Africans have consumed over the period.
The data comes from Nasa spacecraft that can detect changes in gravity caused by water as it cycles between the sea, the atmosphere and the land.

Title: Climatic consequences of regional nuclear conflicts
Authors: A. Robock, L. Oman, G. L. Stenchikov, O. B. Toon, C. Bardeen, R. P. Turco

We use a modern climate model and new estimates of smoke generated by fires in contemporary cities to calculate the response of the climate system to a regional nuclear war between emerging third world nuclear powers using 100 Hiroshima-size bombs (less than 0.03% of the explosive yield of the current global nuclear arsenal) on cities in the subtropics. We find significant cooling and reductions of precipitation lasting years, which would impact the global food supply. The climate changes are large and long-lasting because the fuel loadings in modern cities are quite high and the subtropical solar insolation heats the resulting smoke cloud and lofts it into the high stratosphere, where removal mechanisms are slow. While the climate changes are less dramatic than found in previous "nuclear winter'' simulations of a massive nuclear exchange between the superpowers, because less smoke is emitted, the changes are more long-lasting because the older models did not adequately represent the stratospheric plume rise.

By absorbing half of the carbon dioxide emitted into the atmosphere, the oceans have a profound influence on climate. However, their ability to take up this carbon dioxide might be impaired as a result of climate change. To determine their response to global warming, ESA has backed two projects that provide systematic data on key oceanic variables – colour and temperature.

Winter is coming again to Britain's largest National Park. But life in the Cairngorms is changing with alarming speed. Rising temperatures are having dramatic effects on flora and fauna. So is this spectacular region facing its greatest eco-catastrophe since the Ice Age?

UN annual summit

The United Nations annual summit on climate change this week in Nairobi, Kenya, seeks to negotiate a successor to the Kyoto Protocol strategy, which becomes obsolete in 2012, to restrict emissions of heat-trapping gases that drive climate change. ESA joins the activities to share results of its satellite-based Kyoto-supporting services.
