Fire Earth

Earth is fighting to stay alive. Mass dieoffs, triggered by anthropogenic assault and fallout of planetary defense systems offsetting the impact, could begin anytime!

A Herculean task, significant impact on physical and biological systems globally, worst cases in 800,000 years

“In my view, climate change and the loss of biodiversity are the most alarming challenges on the global agenda,” Environment Minister Sigmar Gabriel said at the opening of a U.N. biodiversity conference on Monday.

“In my view, climate change [Germany is the world’s 6th largest pollutor] and the loss of biodiversity are the most alarming challenges on the global agenda […] It will be a Herculean task to get the world community and each individual country on the right path to sustainability [still talking about ‘Tending Our Goats at the Edge of Apocalypse’] … The truth today is that we are still on the wrong track. If we follow this path we can foresee that we will fail to meet the target … Business as usual is no more an option if humanity is going to survive. Losing biodiversity is not just losing trees and species, it is an economic and security loss. [Thanks for reading our blogs, Mr Gabriel!]” (Source)

Attributing physical and biological impacts to anthropogenic climate change

Significant changes in physical and biological systems are occurring on all continents and in most oceans, with a concentration of available data in Europe and North America. Most of these changes are in the direction expected with warming temperature. Here we show that these changes in natural systems since at least 1970 are occurring in regions of observed temperature increases, and that these temperature increases at continental scales cannot be explained by natural climate variations alone. Given the conclusions from the Intergovernmental Panel on Climate Change (IPCC) Fourth Assessment Report that most of the observed increase in global average temperatures since the mid-twentieth century is very likely to be due to the observed increase in anthropogenic greenhouse gas concentrations, and furthermore that it is likely that there has been significant anthropogenic warming over the past 50 years averaged over each continent except Antarctica, we conclude that anthropogenic climate change is having a significant impact on physical and biological systems globally and in some continents.

Greenhouse gases highest in 800,000 years

Atmospheric greenhouse gases are now at the highest levels in 800,000 years, according to a study of Antarctic ice, which provides additional evidence that human activity is disrupting the climate.

“We can firmly say that today’s concentrations of carbon dioxide and methane are 28 and 124 percent higher respectively than at any time during the last 800,000 years,” said Thomas Stocker, a researcher at the University of Berne. (Source)
