The 10 things you need to know from the new IPCC climate report

The chair of the Intergovernmental Panel on Climate Change, Rajendra Pachauri, called today’s report the “strongest, most robust and most comprehensive” to come out of the IPCC, which has been tracking climate change since 1988. It is “yet another wake-up call to the global community that we must act together swiftly and aggressively,” the White House said in a statement. The report’s language is stronger than in years past: Warming is “unequivocal,” and the changes we’re seeing are pervasive, it states clearly. We must take action quickly to cut our dependence on fossil fuels, it warns. If we don’t, we’ll face “further warming and long-lasting changes in all components of the climate system, increasing the likelihood of severe, pervasive and irreversible impacts for people and ecosystems.”

As we explained last week, you may be experiencing déjà vu — that’s because there have been three IPCC reports released since September 2013. Revue des revues n° 4. 1.

Le climat, roche Tarpéienne pour l’humanité ? Il n’est sans doute pas incongru d’introduire un article relatif au bouleversement du climat en évoquant la croissance, sans que ce soit le lieu ici d’en évoquer ni le bien-fondé, ni le contenu. Il s’agit simplement d’avoir présentes à l’esprit, quand on lira l’analyse du GIEC, quelques données de base. La croissance du produit intérieur brut (PIB), estimé en dollars courants (sous parité de pouvoir d’achat [1]) de la planète est beaucoup plus rapide que celle de la population qui l’habite. Pour avoir été critiqués, les travaux d’Angus Maddison, n’en demeurent pas moins la référence en matière de données chiffrées depuis le premier siècle.

Dans cette étude, le PIB du premier siècle est chiffré à quelque 100 millions de dollars et celui de 2010 à 74 000 milliards de dollars. 1.1 - Cinquième rapport d’évaluation GIEC Conséquence : vulnérabilité et adaptation dans un monde complexe et en évolution. 1.2 - Rapport OMM 2013 Et la Chine ? 2. 3. The U.N.’s latest report on climate change is terrifying. Yep, we know that greenhouse gas emissions are through the roof, and that climate change is already happening in a big, bad way, and that it’s only getting worse.

The U.N.’s latest report on climate change is terrifying

But did you see the news stories about the latest draft report from the Intergovernmental Panel on Climate Change (IPCC)? They are positively horrifying! We are royally f#! @%$#cked, everybody. The key word that the report uses to describe our plight: irreversible. From The New York Times: The world may already be nearing a temperature at which the loss of the vast ice sheet covering Greenland would become inevitable, the report said. The IPCC — a team of scientists and other experts appointed by the United Nations to periodically review the latest research on climate science — has been rolling out its fifth assessment report in four installments, and this draft is the latest.

Rapport mars - avril 2014. 10 Charts that Explain Climate Change Mitigation (plus 2 more that explain negotiation) I really love the IPCC (high confidence), but if you read the summary for policymakers (medium confidence), some of the wording doesn’t exactly roll off the tongue (robust evidence, medium agreement).

10 Charts that Explain Climate Change Mitigation (plus 2 more that explain negotiation)

You know what I mean? (medium evidence, medium agreement) This post is an attempt to do a pictorial summary (of the summary) from Climate Change 2014: Mitigation of Climate Change using its main charts. I’ll try to keep it punchy. Here . . . we . . . go (have coffee, will make it through). 1) Emissions Keep Growing Over the last forty years emissions have just kept growing. 2) The Whole Economy Contributes The leading economic sectors for emissions are ‘electricity and heat’ (25%), ‘agriculture, forestry and other land use’ (24%), industry (21%), transport (14%), other energy (10%) and buildings (6%). 3) Economic and Population Growth Drive Emissions Economic growth and population growth are the key drivers of growing emissions. 4) Low Carbon Energy is the Key to Mitigation Keen for more?
