Global warming continues and won’t be stopped by wishful thinking

Global warming has continued rapidly in recent years, mostly accumulating in the oceans. Yet there remains a pervasive myth that it has somehow magically stopped. Most recently displaying this confusion was Georgia Tech climate scientist Judith Curry, who testified about climate change before a US Senate committee. Curry’s testimony was riddled with mistakes and misleading arguments, in her testimony, the worst of which involved disputing that climate scientists are more confident in human-caused global warming than they were six years ago.

A united call for action on climate change

Kofi Annan is chair of The Elders, a group of independent leaders who work for peace, justice and human rights worldwide. When Nelson Mandela formed the Elders in 2007 to promote peace and human rights across the world, he challenged us to be bold and to give a voice to those who have none. No issue demands these qualities more than our collective failure to tackle climate change.

Cambiamenti climatici: quali rischi per la salute?

Le condizioni ambientali influenzano la qualità di vita e la salute degli individui. E’ sempre più diffusa la consapevolezza dei rischi che possono emergere, per esempio, da una scarsa qualità dell’acqua o dall’alta concentrazione di sostanze inquinanti nell’aria, e i dati parlano chiaro: l’inquinamento dell’aria è causa, ogni anno, di circa 1,3 milioni di decessi nel mondo. Una recente revisione di un migliaio di ricerche scientifiche svolta dall’International Agency for Research on Cancer (IARC), agenzia specializzata dell’Organizzazione Mondiale della Sanità (OMS), ha classificato l’inquinamento atmosferico tra le cause principali del cancro ai polmoni [1]; un quarto dei decessi di bambini a livello mondiale sono attribuibili ad ambienti insalubri e insicuri.

The polar vortex in no way disproves climate change

Almost half of the Lower 48 will shiver under sub-zero wind chills Tuesday morning. Countless records will be set. Yet none of that means a thing about the existence of climate change, its severity or its consequences.

November Was Cold, But the Climate Keeps Warming

Global warming is a misnomer. “Warming” makes it sound as if the climate will get hotter at a steady, predictable pace—like a pot of soup heating on the stove. But that’s not how our enormously complex climate system works. The increasing concentration of carbon dioxide and other warming gases in the atmosphere is just one of many factors affecting the global climate—including the natural year-to-year variability that has always been at work. Over the short term, temperatures can rise and fall like the fluctuating value of a single company in the stock market. But the long-term trends—the important trends—remain unchanged.

Why climate change threatens Peru’s poverty reduction mission

The Peruvian Amazon became a net emitter of carbon dioxide rather than oxygen for the first time in 2012, according to the UN Development Programme’s (UNDP) latest human development country report. The reversal of the rainforest’s usual role as a carbon sink is a direct result of the droughts in the western Amazon in 2005 and 2010 – and a stark reminder, say scientists, that this mega-biodiverse country is highly vulnerable to climate change.
