once in a while, it's good to remind oneself of the bigger picture
1. global warming and climate change can be stopped

"There are multiple mitigation pathways that are likely to limit warming to below 2°C relative to pre-industrial levels.

2. goal and time frame are clear: "Zero emissions by 2100"

"These pathways would require substantial emissions reductions over the next few decades and near zero emissions of CO2 and other long-lived greenhouse gases by the end of the century.

3. The solution space is complex and Technology Alone won't solve it all

"Implementing such reductions poses substantial technological, economic, social and institutional challenges, which increase with delays in additional mitigation and if key technologies are not available.

4. Effective climate change mitigation hinges upon the global energy transition

"In scenarios reaching 450 ppm CO2-eq concentrations by 2100, global CO2 emissions from the energy supply sector are projected to decline over the next decade and are characterized by reductions of 90% or more below 2010 levels between 2040 and 2070.

5. In the coming decades we need a complete fuel switch in the electricity sector

"In the majority of low-concentration stabilization scenarios, the share of low-carbon electricity supply (comprising renewable energy (RE), nuclear and CCS, including BECCS) increases from the current share of approximately 30% to more than 80% by 2050 and 90% by 2100, and fossil fuel power generation without CCS is phased out almost entirely by 2100.

6. Coordinating the transitions of the energy, transport, building Sectors will pay off

"Mitigation options are available in every major sector. Mitigation can be more cost-effective if using an integrated approach that combines measures to reduce energy use and the greenhouse gas intensity of end-use sectors, decarbonize energy supply, reduce net emissions and enhance carbon sinks in land-based sectors.

7. Stringent policies and Effective governance are key

"Effective adaptation and mitigation responses will depend on policies and measures across multiple scales: international, regional, national and sub-national. Policies across all scales supporting technology development, diffusion and transfer, as well as finance for responses to climate change, can complement and enhance the effectiveness of policies that directly promote adaptation and mitigation.
