CLIMATE CHANGE
ATMOSPHERIC CO2
Massively increased concentrations in the atmosphere since 1880
|
Increase in CO2 concentration in the atmosphere mainly due to human activity: industry, transportation, increased population.
|
Land and sea temperatures are rising over a similar time period as shown in this graph.

CORRELATION: Very strong

GHG-emissions-history-1854–2010-by-Richard-Heede-2013.pdf
This paper presents a quantitative analysis of the historic fossil fuel and cement production records of the 50 leading investor-owned, 31 state-owned, and 9 nation-state producers of oil, natural gas, coal, and cement from as early as 1854 to 2010. This analysis traces emissions totaling 914 GtCO2e—63 % of cumulative worldwide emissions of industrial CO2 and methane between 1751 and 2010—to the 90 “carbon major” entities based on the carbon content of marketed hydrocarbon fuels (subtracting for non-energy uses), process CO2 from cement manufacture, CO2 from flaring, venting, and own fuel use, and fugitive or vented methane. Cumulatively, emissions of 315 GtCO2e have been traced to investor-owned entities, 288 GtCO2e to state-owned enterprises, and 312 GtCO2e to nation-states. Of these emissions, half has been emitted since 1986. The carbon major entities possess fossil fuel reserves that will, if produced and emitted, intensify anthropogenic climate change. The purpose of the analysis is to understand the historic emissions as a factual matter, and to invite consideration of their possible relevance to public policy.

CLIMATE CHANGE ... Hansen etal predictions 2015
RISK-p3-14 ... Some highlights from the Hansen etal report of 2015
James Hansen and many other scientists have been working on the matter of climate change for a long time. Climate change is very complicated, but the evidence is that we are facing change that has not been seen in MILLIONS of years. We are not facing a 100 year storm, but a disruption that happens only a few times in the life of the planet. This Hansen report should be a wake up call to decision makers. It further justifies the MDIA rethink of how we do metrics about all decision making and the accounting for risk.
