Atmospheric carbon dioxide emissions will soon pass 400 parts per million (ppm), up from 316 ppm in 1958 when modern record keeping began and an estimated 280 ppm at the start of the Industrial Revolution, according to the Scripps Institution of Oceanography at University of California, San Diego.
Natural variability alone cannot explain the recent (past century) warming trend, confirms a new study published in Nature Geoscience.
The annual range of precipitation has increased across the globe, mostly due to the fact that wet seasons have become wetter, according to a new study published in Nature Geoscience.
By the year 2100, surface temperatures will exceed those of the Holocene (the past about 11,300 years), according to new research published in Science.
Last year was the 10th warmest year for the globe since records began in 1880, making it the 36th consecutive year in which global temperatures were above average, according to a recent analysis by NOAA. What’s more, all 12 years in the 21st century have been among the 14 warmest years on record, with 2010 and 2005 ranking as warmest and second warmest, respectively.
Climate change costs the world $1.2 trillion, or 1.6 percent of global GDP, per year, according to a new report by DARA, a European nongovernmental organization, and the Climate Vulnerable Forum, a semi-formal government group made up of developing countries.
A new study, conducted by Richard Muller (a known climate change denier) and other scientists from Berkeley Earth, shows that the Earth has warmed about 2.7 degrees F in the last 250 years, and that this warming closely follows carbon dioxide concentrations.
The average global temperature in May was the second warmest on record, with a combined global land and ocean surface temperature of 1.19 degrees F above the 20th century average, according to the newest State of the Climate from NOAA.
Two new reports warn the world is on an unsustainable path and is moving towards a ‘tipping point’.
