Washington. AFP temperatures rise, greenhouse gases hit record peaks and glaciers of the Arctic melt, making 2013 one of the warmest years on record.

So what scientists warned in the annual report on the state of climate science journal with climate data and events compiled by 425 scientists from 57 countries.

"These results reinforce what scientists observed for decades: that our planet is transformed into a warmer place," said Kathryn Sullivan, president of the National Oceanic and Atmospheric Administration.

In 2013, global temperatures were among the highest in the records began in the early twentieth century.

"Australia had its warmest year, while for Argentina was the second warmest and New Zealand, the third," the document states.

The surface temperature of the oceans and seas also rose last year and was placed among the 10 warmest it has been, while the Arctic had its seventh warmest year.

The ice in the Arctic was the sixth less extensive since 1979, when satellite observations began.

On average, water levels also rose, maintaining an upward trend of about three millimeters per year in the past two decades.

Emissions of greenhouse gases resulting from the combustion of fossil fuels continued to increase during 2013, again reaching historic peaks.

For the first time, the daily concentration of carbon dioxide in the atmosphere exceeded 400 parts per million (ppm), measured according to the Mauna Loa Observatory in Hawaii, one year after other observatories FILED 400 ppm in the Arctic.

The report was published in the scientific journal Bulletin of the American Meteorological Society.

"Provides a detailed scientific view of what is happening in our world," said Keith Seifer, who served as director of the group of scientists in charge of the report.
