Climate Change & Anthropocene Extinction 5: What are the IPCC predictions for biodiversity loss?

Climate change is a direct disturbing factor to ecosystem health. It also leads to geographical biome shifts and therefore forced species migrations. Invasive species and food chain disturbances can lead to plagues, creating further ecosystem damage. All these factors work … Continue reading

Real Global Temperature Trend, p23 – Climate sensitivity has large geographical spread: 2-3 degrees global average equals 6+ in the Arctic

Why climate change is such a killer? Because disruption is never a linear process. We see that with ecosystem disintegration – where beyond a certain threshold cascading damage sets in – leading to shifts and collapse scenarios that are easy … Continue reading

IPCC graph of the day: bridging a gap of >600 ppm – immediate clamp down on fossil fuels required

Yesterday we took a look at what we have been doing over the past 40 years. Now we take a look at what we will be doing over the rest of the 21st century. It’s a real shocker to look … Continue reading

Permian-Triassic climate lesson: Don’t even try to adapt to a mass extinction, mitigate – a single plague can kill a planet!

The second part of the new IPCC report, about the impacts of climate change, has been released on Monday. Across the globe dutiful journalists filled the headlines of their newspapers – and as they presume most of their readers are … Continue reading

Despite recession carbon emissions keep rising to new records

We knew CO2 emissions reached a new record high in 2010, at 30.6 gigatonnes. Now a new study by CICERO, the Tyndall Centre and other institutes reconfirms the strong rebound after the 2008 global financial crisis – and predicts that … Continue reading

Good news? According to paleo research median CO2 climate sensitivity could be 0.7 degrees lower

The most-quoted climate sensitivity range (IPCC 4AR) suggests a median temperature response to a doubling of the atmospheric CO2 concentration of 3 degrees Celsius – and a 66 percent probability range warming under CO2-doubling will be somewhere between 1.5 and … Continue reading
