By 2100, extreme heat waves could cover 80 percent of the globe
Hundreds of thousands of East Coasters suffered through hot and sticky climates for much of July, as temperatures reached record highs in some places. Although these types of extreme heat waves are unusual, they will become more frequent and severe across the globe in the next 30 years, and there’s nothing that can be done about it, according to a new study from a team of international researchers.
Most environmental and climate researchers believe that extreme heat waves are the result of global warming and high levels of carbon dioxide being released into the atmosphere. But no matter what actions are taken to reduce carbon dioxide emissions, intense summer heat waves are expected to Read more…
The seeds of conflict take root.
This is one of the scenarios Joachim Schellnhuber, director of the Potsdam Institute for Climate Impact Research, presented today to members of the United Nations Security Council in New York to show the connection between climate change and global security challenges.
Either rich nations will find a way to supply needy nations suffering from damaging climate effects “or you will have all kinds of unrest and revolutions, with the export of angry and hungry people to the industrialised countries,” Schellnhuber said in an interview.

While we in Australia are looking forward to celebrating Christmas and the holidays, we should spare a thought for the Christians who are suffering persecution in so many countries. Even in democracies such as the US and Canada, Christians can be fined or lose their jobs for imaginary “hate” crimes, i.e. speaking about the health risks of some homosexual practices or declining to provide services for homosexual “marriages”.
It is persecution in developing countries that is most distressing to me because Christians there rarely have the financial resources to seek legal redress. Below some news items from the weekly email I receive from Christians in Crisis:
Iran: Two of the seven members of the Church of Iran arrested in Shiraz have been temporarily released on bail.
Indonesia: Church building set ablaze – Unidentified attackers torched a church building in Poso in a series of renewed violence against the local Christian community.
Egypt: A call to pray for an end to the abduction, forced conversion and forced marriage of Coptic girls by Islamist Salafis.

How much extra energy are we putting in the atmosphere through emission of greenhouse gases? One Australian researcher put it into context: “The radiative forcing of the CO2 we have already put in the atmosphere in the last century is … the equivalent in energy terms to almost half a billion Hiroshima bombs each year.”
With more energy radiating down on the planet rather than back up into space, the planet continues to heat up. As the atmosphere warms, it is able to hold more water vapor — thus strengthening the global hydrological cycle.
With all that extra energy, more water is pulled out of the subtropic regions and moved toward higher-precipitation areas in the subpolar regions, resulting in stronger droughts and stronger storms. Or, as the video below explains, how the wet gets wetter and the dry gets drier.
Through five decades of observations and future climate modeling, the National Oceanic and Atmospheric Administration has put together this educational piece on how a warming planet will make weather more extreme: Read more…
Food prices hit record highs in February 2011 and stoked protests connected to the Arab Spring wave of civil unrest in some North African and Middle Eastern countries. They then receded, but started to grow again in January.
The index, which measures monthly price changes for a food basket of cereals, oilseeds, dairy, meat and sugar, averaged 215,9 points in March, up from a revised 215,4 points in February, FAO data showed.
Its cereal price index averaged 227 points in March, up from February, with maize prices showing gains, supported by low inventories and a strong soybean market, the FAO said.
“You can see prices in the near term rising even further,” FAO’s senior economist and grain analyst Abdolreza Abbassian said before the index update.
The FAO also confirmed its earlier forecast for world wheat output to fall 1,4% from Read more…
(NaturalNews) The Office of the Director of National Intelligence (ODNI) recently released a report entitled Global Water Security that claims water supply issues around the globe will lead to economic instability, civil and international wars, and even the use of water as a weapon in the next several decades. In typical shock-and-awe fashion, the U.S. government paints a grim picture of so-called global warming, water shortages, and other water problems as the causes of major global destabilization, which it also says may be mitigated if certain steps are taken to offset them.
What are these steps, you may ask? As expected, getting the U.S. government involved in water supply issues around the globe is presented as a primary solution. This measure implies, of course, that U.S. models of water management, which include price-gouging the public in the name of water conservation, will also be implemented across the Read more…
Seasonal Jun-Jul-Aug 2010 sea surface temperature (SST) anomalies relative to 1951–70. Record high SSTs were recorded in the locations and at the times indicated with record flooding nearby.
Curious about the connection between global warming and extreme weather? You ought to be. And who better to learn about this from than National Center for Atmospheric Research senior scientist Kevin E. Trenberth?
