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
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
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
And now it has to go sharply down. To summarise the entire IPCC WG3 report on climate mitigation:
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
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
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
The image to the right wasn’t leaked, but neatly published in 2007 – the old IPCC report. It still does a good job explaining the logic.
If we can’t bring actual emissions down to within the IPCC projections range – than why don’t we bend the spectrum upwards. It’s easier.
