U.N. climate summit is high-profile, but some of world’s most important leaders will skip it

This week, the United Nations will host a huge and well-publicized one-day summit on climate change. The public is likely to be watching it closely: It comes just days after thousands of people in New York and around the world took to the streets, demanding more political action to help fight global warming. The climate summit’s organizer, U.N. Secretary General Ban Ki-moon, took part in the New York march, and for Tuesday’s event, he is promising to bring together a some of the most powerful people in the world with a common purpose. “I have invited leaders from government, business, finance and civil society to present their vision, make bold announcements and forge new partnerships that will support the transformative change the world needs,” he wrote in a blog post on the summit for the Huffington Post.

6 Ways Climate Change is Making Us Sick

Climate change and global health are intimately connected new research argues

Just a day after the People’s Climate March, one of the largest international environmental marches, a new analysis of 56 studies on climate change-related health problems shows that increasingly, global temperatures and severe weather events will continue to have a major impact on global health. In the U.S. alone, several cities are expected to experience many more frequent hot days by the year 2050, and New York City and Milwaukee for example, may have three times their current average of hot days that reach over 90 degrees. According to researchers from the University of Wisconsin, this is just one consequence of human-driven climate change. Currently, 97% of scientists studying climate agree that climate change is caused by humans. The new study, which is published inJAMA, lays out what these wide ranging effects on public health are.

Gas serra oltre ogni record

Secondo un nuovo report dell’Organizzazione Metereologica Mondiale sono confermate le concentrazioni record di gas serra nell’atmosfera. Intanto il mare si sta acidificando ad una velocità mai avvenuta in 300 milioni di anni. La prognosi è grave. Ancora più acuta di quanto già gli scienziati prevedevano. Secondo un nuovo report ottenuto in anteprima da La Stampa del World Meteorological Organization, l’Organizzazione Metereologica Mondiale è stato confermato il record di concentrazione di gas serra, negli oceani e nell’atmosfera, in particolare di biossido di carbonio, la CO2, il più impattante dei gas climateranti. Apparentemente il Greenhouse Gas Bulletin, questo il titolo del documento, potrebbe essere bollato come “l’ennesimo report sull’andamento del clima”.

U.N. Draft Report Lists Unchecked Emissions’ Risks

Runaway growth in the emission of greenhouse gases is swamping all political efforts to deal with the problem, raising the risk of “severe, pervasive and irreversible impacts” over the coming decades, according to a draft of a major new United Nations report.

Global warming is already cutting grain production by several percentage points, the report found, and that could grow much worse if emissions continue unchecked. Higher seas, devastating heat waves, torrential rain and other climate extremes are also being felt around the world as a result of human-produced emissions, the draft report said, and those problems are likely to intensify unless the gases are brought under control.

Eight ways climate change is making the world more dangerous

Forget the future. The world already is nearly five times as dangerous and disaster prone as it was in the 1970s, because of the increasing risks brought by climate change, according to a new report from the World Meteorological Organisation. The first decade of the 21st century saw 3,496 natural disasters from floods, storms, droughts and heat waves. That was nearly five times as many disasters as the 743 catastrophes reported during the 1970s – and all of those weather events are influenced by climate change.

8 Summer Miseries Made Worse by Global Warming

With average global temperatures expected to rise more than 3.6 degrees Fahrenheit (2 degrees Celsius) over the coming decades, a new report from a leading U.S. environmental group warns that future summers are likely to be filled with more misery, from more prolific poison ivy and biting insects to worsened air and water quality and impacts on tourism. “Summer has always been a time many people look forward to, but climate change is causing more and more threats that we need to be mindful of,” says Kim Knowlton, a co-author of the new report and senior scientist with the New York-based Natural Resources Defense Council (NRDC).
