New study predicts much hotter new world, as another shows increase in greenhouse gas

In a very worrying but unconnected set of circumstances, two related reports on climate were released this week.

A new study published this week in the respected online journal Nature was led by a biological geographer at the University of Hawaii and indicates some very worrying predictions.

The volume of carbon dioxide, or CO2 grew faster in 2012 than in the previous decade, reaching 393.1 parts per million (ppm), 41 per cent above the pre-industrial level, the WMO reports. Methane levels are grew at the same rate in the last few years. © AP

This study says several cities will become unbearable hot in just a few years time.

Kingston Jamaica will be affected permanently in about a decade, followed by Singapore in 2028, Mexico City by 2031, and Cairo by 2036.  Much of the entire world will be hotter than ever before by 2047 says the report.

To arrive at their projections, the researchers used weather observations, computer models and other data to calculate the point at which every year from then on will be warmer than the hottest year ever recorded over the last 150 years.

Lead author Camilo Mora and colleagues ran simulations from 39 different computer models and looked at hundreds of thousands of species, maps and data points to ask when places will have “an environment like we had never seen before.”

The 2047 date for the whole world is based on continually increasing emissions of greenhouse gases from the burning of coal, oil and natural gases. If the world manages to reduce its emissions of carbon dioxide and other gases, that would be pushed to as late as 2069, according to Mora

He said one of their measurements looking at ocean acidity indicates the oceans crossed into a new regime in 2008, with evey year since getting more acidic than previously.

Environment Canada said in a statement that it is familiar with the study, “which is based on credible science using an ensemble of climate models, including Canada’s earth system model.”

The actions we take now or don’t take now will have consequences for a very, very long period,” said Michel Jarraud, Secretary-General of World Meteorological Organization, WMO, said at a press conference Wednesday © AP

Meanwhile the World Meteorological Organization said this week that  atmospheric volumes of greenhouse gases blamed for climate change hit a new record in 2012,

For all these major greenhouse gases the concentrations are reaching once again record levels,” WMO Secretary-General Michel Jarraud told a news conference in Geneva at which he presented the U.N. climate agency’s annual Greenhouse Gas Bulletin

He said the concentrations were the highest they’ve been in more than 800,000 years.

“The increase in CO2 is mostly due to human activities,” Jarraud said. “The actions we take now or don’t take now will have consequences for a very, very long period.”

Netiquette »

When you express your personal opinion in an online forum, you must be as courteous as if you were speaking with someone face-to-face. Insults and personal attacks will not be tolerated. To disagree with an opinion, an idea or an event is one thing, but to show disrespect for other people is quite another. Great minds don’t always think alike—and that’s precisely what makes online dialogue so interesting and valuable.

Netiquette is the set of rules of conduct governing how you should behave when communicating via the Internet. Before you post a message to a blog or forum, it’s important to read and understand these rules. Otherwise, you may be banned from posting.

  1. RCInet.ca’s online forums are not anonymous. Users must register, and give their full name and place of residence, which are displayed alongside each of their comments. RCInet.ca reserves the right not to publish comments if there is any doubt as to the identity of their author.
  2. Assuming the identity of another person with intent to mislead or cause harm is a serious infraction that may result in the offender being banned.
  3. RCInet.ca’s online forums are open to everyone, without regard to age, ethnic origin, religion, gender or sexual orientation.
  4. Comments that are defamatory, hateful, racist, xenophobic, sexist, or that disparage an ethnic origin, religious affiliation or age group will not be published.
  5. In online speak, writing in ALL CAPS is considered yelling, and may be interpreted as aggressive behaviour, which is unpleasant for the people reading. Any message containing one or more words in all caps (except for initialisms and acronyms) will be rejected, as will any message containing one or more words in bold, italic or underlined characters.
  6. Use of vulgar, obscene or objectionable language is prohibited. Forums are public places and your comments could offend some users. People who use inappropriate language will be banned.
  7. Mutual respect is essential among users. Insulting, threatening or harassing another user is prohibited. You can express your disagreement with an idea without attacking anyone.
  8. Exchanging arguments and opposing views is a key component of healthy debate, but it should not turn into a dialogue or private discussion between two users who address each other without regard for the other participants. Messages of this type will not be posted.
  9. Radio Canada International publishes contents in five languages. The language used in the forums has to be the same as the contents we publish. The usage of other languages, with the exception of some words, is forbidden. Messages that are off-topic will not be published.
  10. Making repetitive posts disrupts the flow of discussions and will not be tolerated.
  11. Adding images or any other type of file to comments is forbidden. Including hyperlinks to other websites is allowed, as long as they comply with netiquette. Radio Canada International  is in no way responsible for the content of such sites, however.
  12. Copying and pasting text written by someone else, even if you credit the author, is unacceptable if that text makes up the majority of your comment.
