The Intergovernmental Panel on Climate Change (IPCC) is broadly viewed as the world’s most legitimate scientific assessment body that periodically assesses the economics of climate change (among many other topics) for policy audiences. However, growing procedural inefficiencies and limitations to substantive coverage have made the IPCC an increasingly unattractive forum for the most qualified climate economists. Drawing on our observations and personal experience working on the most recent IPCC report, published last year, we propose four reforms to the IPCC’s process that we believe will lower the cost for volunteering as an IPCC author: improving interactions between governments and academics, making IPCC operations more efficient, clarifying and strengthening conflict of interest rules, and expanding outreach. We also propose three reforms to the IPCC’s substantive coverage to clarify the IPCC’s role and to make participation as an author more intellectually rewarding: complementing the IPCC with other initiatives, improving the integration of economics with other disciplines, and providing complete data for policymakers to make decisions. Despite the distinct characteristics of the IPCC that create challenges for authors unlike those in any other review body, we continue to believe in the importance of the IPCC for providing the most visible line of public communication between the scholarly community and policymakers.

The Intergovernmental Panel on Climate Change (IPCC) reports on climate change have served to alert both the public and policymakers about the scope of the predicted changes and the effects they would have on natural and economic systems. The first IPCC report was published in 1990, since which time a further four have been produced. The aim of this study was to conduct a content analysis of the IPCC Summaries for Policymakers in order to determine the degree of certainty associated with the statements they contain. For each of the reports we analyzed all statements containing expressions indicating the corresponding level of confidence. The aggregated results show a shift over time towards higher certainty levels, implying a “Call to action” (from 32.8% of statements in IPCC2 to 70.2% in IPCC5). With regard to the international agreements drawn up to tackle climate change, the growing level of confidence expressed in the IPCC Summaries for Policymakers reports might have been a relevant factor in the history of decision making.


Subject African illegal wildlife trade. Significance A recent UK-hosted conference on the Illegal Wildlife Trade (IWT) and a UN Intergovernmental Panel on Climate Change (IPCC) report have highlighted the importance of wildlife and wilderness protection in Sub-Saharan Africa (SSA) and the integral connections between wildlife protection and climate change. Pressure is starting to grow on governments and businesses to protect irreplaceable biodiversity but progress faces several obstacles. Impacts The EU may increase aid for African biodiversity protection as climate change impacts risk increased African migrant numbers to Europe. Growing pressure may encourage institutional investors to divest from fossil fuels towards the renewable energy sector and ecotourism. Civil society pressure could mount to redirect global aid budgets partially towards wilderness landscape preservation. A South African ruling overturning government approval for a coal mine on critical biodiversity-protecting land may set a major precedent.

Governments, corporations and individuals all need to take immediate action to help change the global economy toward a circular economy. A circular economy which uses fewer resources and based on renewable clean technologies to help limit global warming to 1.5 °C. The 2018 Intergovernmental Panel on Climate Change (IPCC) report warned that limiting global warming to 1.5 °C above pre-industrial levels would require current greenhouse-gas (GHG) emissions to be cut in half by 2030. Yet actions by governments, corporations and individuals are lagging behind. Many countries are failing their obligations made under the 2015 Paris climate agreement. Even the International Maritime Organization, a United Nations agency set a 50% reduction target of GHG emissions for global shipping by 2050, but this falls short of the IPCC target by 20 years. The United Nations climate summit in New York this week (September 2019) needs to send a strong wake up call to the entire world for us all to change. Change makers like Greta Thunberg has already done that. Individual actions to change consumer behaviour can play a major role to help reduce GHG emissions. Even reducing use of single-use plastics (a petroleum derivative) and incineration can help reduce GHG emissions. GHG emissions from plastics could reach 15% of the global carbon budget by 2050 if not curbed. In Europe, plastic production and incineration emits an estimated ~400 million tonnes of CO2 per year. Therefore, reducing single-use plastic use could curb GHG emissions.

Major polar ice sheets and ice caps experience cycles of variable flow during different glacial periods and as a response to past warming. The rate and localisation of deformation inside an ice body controls the evolution of ice microstructure and crystallographic fabric. This is critical for interpreting proxy signals for climate change, with deformation overprinting and disrupting stratigraphy deep under ice caps due to the nature of the flow. The final crystallographic fabric in polar ice sheets provides a record of deformation history, which in turn controls the flow properties of ice during further deformation and affects geophysical sensing of ice sheets. For example, identification of layering in ice sheets, using seismic or ice radar techniques, is attributed to grain size changes and fabric variations. Such information has been used to provide information on climate state and its changes over time, and as the Fourth Intergovernmental Panel on Climate Change (IPCC) Report (Solomon et al. 2007) points out there is currently still a lack of understanding of internal ice-sheet dynamics. To answer this we have recently conducted experiments at the Australian Nuclear Science and Technology Organisation (ANSTO) to collect fully quantitative microstructural data from polycrystalline heavy water (D2O) ice deformed in a dynamic regime. The ice and temperature (–7°C) chosen for this study is used as a direct analogue for deforming natural-water ice as it offers a unique opportunity to link grain size and texture evolution in natural ice at –10°C. Results show a dynamic system where steady-state rheology is not necessarily coupled to microstructural and crystallographic fabric stability. This link needs to be taken into account to improve ice-mass-deformation modelling critical for climate change predictions.

When the democratic government came into power in 1994 in South Africa, it faced formidable problems stemming from the structural and historical inequalities and imbalances created by apartheid. Among the challenges included climate change. The release of the 2013 Intergovernmental Panel for Climate Change (IPCC) report indicates that climate change is a reality and its effects globally are getting worse daily. However, South African youth have not been adequately educated about climate change through formal basic schooling so that they can act as change agents.This article argues that the curriculum has to include relevant and the most recent content on climate change so that children can become agents of climate change in their homes and communities. The article uses content analysis of the National Curriculum Statement (2012) to determine the relevance and currency of climate change content in the present basic schooling curriculum. The article also makes recommendations on how the present content can be revised and made relevant to South African schools.

Another international climate change summit, this time in the Qatari city of Doha, has concluded without a binding agreement reached on reducing global greenhouse gas emissions. The failure of 18th Conference of the Parties (COP18) was anticipated beforehand by everyone involved, and met with widespread indifference on the part of international media. Since, the debacle at Copenhagen summit in December 2009—which broke up without agreement on a post-Kyoto climate treaty amid bitter conflicts between the major powers — annual UN-sponsored climate summits have been restricted to negotiating various secondary issues, unrelated to the question of binding emissions targets. Heads of government have not gathered to discuss the issue in past three years, leaving junior ministers and diplomats to head negotiating teams at the subsequent summits at Cancun, Durban, and Doha. The inability of world leaders to even meet to discuss the climate change crisis, represents a devastating indictment of capitalist system. Overwhelming scientific evidence points to the serious threat posed to world's population by excessive emissions of carbon dioxide and other greenhouse gases. The forecasts made in first UN Intergovernmental Panel on Climate Change (IPCC) Report, in 1990, have proven accurate. “We've sat back and watched the two decades unfold and warming has progressed at a rate consistent with those projections,” Matt England, of the University of New South Wales' Climate Change Research Centre, told Australia's ABC Radio. “The analysis is very clear that, IPCC projections are coming true. And at the moment, we are tracking at high end in terms of our emissions, and so all of the projections that we look to at the moment are those high end forecasts.” However, the researchers believe that the conclusions will have a broader implication, that will surely help developing nations in not only reaching, the much sought economic integration among them and reducing Economic Asymmetries with developed nations, but also in reducing the emission levels to save our planet. So, if a revolution has to be there in International trade and globalization, be it the Green Way!

The UN Intergovernmental Panel on Climate Change Report (2007) concluded that the globally averaged net effect of human activities since 1750 has been one of the sources of global warming. The Stern Report (2007) corroborates this statement and states that anthropogenic CO2 influences the climate and stresses that the cost of mitigating against climate change is significantly lower than the cost of climate change. The Tata group companies have been actively seeking out experiences of other global companies to develop an effective action plan against climate change. The present paper seeks to review the role of the Tata group in addressing and abating the climate change. It further looks at the various Tata group companies like Tata Chemicals Limited, Tata Steel Europe, Tata Communications and Tata Motors and their ways to stay the course towards sustainable development
