A new report released by the Met Office and the National Oceanic and Atmospheric Administration (NOAA) has come to the conclusion that there is "unmistakable signs" that "the world is warming".

The report is based on 10 different indicators of temperature changes. According to the Met Office each indicator "proved consistent with a warming world". According to the report the air temperature over land, the sea-surface and marine air temperature has all increased. Our oceans are also heating and the humidity is getting higher. Tropospheric temperature in the ‘active-weather’ layer of the atmosphere closest to the Earth’s surface has also increased. The Met Office also notes that sea-levels has increased while glaciers, spring snow cover in the northern hemisphere and arctic sea-ice are all in decline.

“The temperature increase of one degree Fahrenheit over the past 50 years may seem small, but it has already altered our planet,” said Deke Arndt, co-editor of the report and chief of the Climate Monitoring Branch of NOAA’s National Climatic Data Center.

“Glaciers and sea ice are melting, heavy rainfall is intensifying and heat waves are more common. And, as the new report tells us, there is now evidence that more than 90 percent of warming over the past 50 years has gone into our oceans.”

A draft text for a potential final agreement in Copenhagen was leaked today to the Guardian. The “Danish text” has made the developing countries “furious” as the draft agreement would give even more powers to the rich nations, weakening UN’s future role as well as abandon the Kyoto protocol. Some say this shows the true agenda in Copenhagen, others believe the draft is unofficial and may have changed a lot since its first creation.

The Environmental Protection Agency in the USA has declared that carbon dioxide is a public danger. This would make it possible for Barack Obama to impose his proposed emissions cuts without an agreement in the sceptic U.S. Senate. A report released today by the Center for Biological Diversity claims that Obama now has the clear legal authority to make a binding commitment for greenhouse gas reductions in Copenhagen without waiting for Congress.

The UK Met Office and World Meteorological Organization have announced, in yet another report, that the first decade of this century is “by far” the warmest on record: “The decade of the 2000s (2000–2009) was warmer than the decade spanning the 1990s (1990–1999), which in turn was warmer than the 1980s (1980–1989).” The National Climatic Data Center (NOAA) in USA also released a similar report today: “The 2000 – 2009 decade will be the warmest on record, with its average global surface temperature about 0.96 degree F above the 20th century average. This will easily surpass the 1990s value of 0.65 degree F.”

Gordon Brown says the EU must cut its emissions with 30% by 2020 – but only if an ambitious global deal is reached in Copenhagen: “We’ve got to make countries recognise that they have to be as ambitious as they say they want to be. It’s not enough to say ‘I may do this, I might do this, possibly I’ll do this’. I want to create a situation in which the European Union is persuaded to go to 30%.”

Speaking at Klimaforum09 (Climate Forum 09), the alternative climate conference, in Copenhagen Naomi Klein said this is the last chance we have to save the world, but at the same time she expressed her doubt whether an ambitious deal would be made at the Bella Centre: “The Bella Center is the biggest case of disaster capitalism. The deal we really need is not even on the table.” Klein also criticized the Hopenhagen climate campaign: “The globe has Siemens logo on the bottom and the whole event is sponsored by Coke. That is a capitalization of hope but Klimaforum09 is where the real hope lies,” she said. “Klimaforum is not about giving charity to the developing world its about taking responsibility and the industrialized countries cleaning up our own mess,” she concluded.

The White House says the leaked “climategate” email story is “silly” and that the science is clear: “I think scientists are clear on the science. I think many on Capitol Hill are clear on the science. I think that this notion that there is some debate … on the science is kind of silly.” But just look at these scandalous emails!

Newly released data from the UK Met Office shows that during the first half of 2008 the global temperatures was more than 0.1 Celcius cooler than any other year after 2000. The reason for this is La Nina, an ocean-atmosphere phenomenon that has a cooling effect on the earth.

But this doesn’t mean the deniers are correct about anything else. Scientists still expects that 2008 will be the 10th warmest year since 1850. And the UK Met Office says that the global temperatures will continue to rise again when La Nina eases away.

“The big thing that’s been happening this year is La Nina, which has lowered global temperatures somewhat,” said John Kennedy, climate monitoring and research scientist at the Met Office’s Hadley Centre.

“La Nina has faded in the last couple of months and now we have neutral conditions in the Pacific,” he told BBC News.

Dr Kennedy also said that “2008 will still be significantly above the long-term average,” and that “there’s been a strong upward trend in the last few decades, and that’s the thing to focus on.”

Even during the temporarily cooling effect from La Nina we see evidence that the rapid man-made warming continues. Images from National Aeronautics and Space Administration satellites show continued breakup of 2 of Greenland’s largest glaciers. According to Canadian authorities the Northwest Passage is navigable. Recently scientists warned that the Arctic could become ice-free during the summers as early as 2013. And just yesterday a huge chunk of ice shelf nearly the size of Manhattan broke away in Canada’s northern Arctic.
