Global Change Biology: A Primer
Rowan F. Sage
Read the article: https://doi.org/10.1111/gcb.14893
Because of human action, the Earth has entered an era where profound changes in the global environment are creating novel conditions that will be discernable far into the future. One consequence may be a large reduction of the Earth's biodiversity, potentially representing a sixth mass extinction. With effective stewardship, the global change drivers that threaten the Earth's biota could be alleviated, but this requires clear understanding of the drivers, their interactions, and how they impact ecological communities. This review identifies 10 anthropogenic global change drivers and discusses how six of the drivers (atmospheric CO2 enrichment, climate change, land transformation, species ex...

Using big data in global change biology
Research challenges and opportunities for using big data in global change biology
Jianyang Xia, Jing Wang, Shuli Niu
Read the article: https://doi.org/10.1111/gcb.15317
Global change biology has been entering a big data era due to the vast increase in availability of both environmental and biological data. Big data refers to large data volume, complex data sets, and multiple data sources. The recent use of such big data is improving our understanding of interactions between biological systems and global environmental changes. In this review, we first explore how big data has been analyzed to identify the general patterns of biological responses to global changes at scales from gene to ecosystem. After that, we investigate how observational networks and space‐based big data have facilita...

Climate Change and Global Warming: Explained in Simple Words for Beginners
The term climate change is used to denote the long-term changes in the weather patterns in a given region. Another term often interchanged with climate change is global warming. Global warming is formally defined as a rise in Earth's temperature that persists for a decade or longer.
There could be several causes for climate change, but the biggest one is the rising concentration of greenhouse gases. Simply put, greenhouse gases are those gases in our atmosphere that trap heat. Some examples include carbon dioxide, methane, chlorofluorocarbons, nitrous oxide and ozone.
Natural sources and human activities both result in the emission of greenhouse gases. One of the most common ways these gases get released into the atmosphere is through the burning of fossil fuels. Burning coal or oil to ru...

Pollution - Global Warming - GCSE Biology (9-1)
This video is for Edexcel IGCSE Biology 9-1 but is relevant for many GCSE Biology courses. It covers the following objectives from the syllabus
4.13 Understand that water vapour, carbon dioxide, nitrous oxide, methane and CFCs are greenhouse gases.
4.14 Understand how human activities contribute to greenhouse gases.
4.15 Understand how an increase in greenhouse gases results in an enhanced greenhouse effect and that this may lead to global warming and its consequences.

Hanson, Paul; Walker, Anthony
Read the article: https://doi.org/10.1111/gcb.14894
This commentary summarizes the publication history of Global Change Biology for works on experimental manipulations over the past 25 years and highlights a number of key publications. The retrospective summary is then followed by some thoughts on the future of experimental work as it relates to mechanistic understanding and methodological needs. Experiments for elevated CO2 atmospheres and anticipated warming scenarios which take us beyond historical analogs are suggested as future priorities. Disturbance is also highlighted as a key agent of global change. Because experiments are demanding of bot...

Human Impacts on Biodiversity | Ecology and Environment | Biology | FuseSchool
Biodiversity is the variety of life. There are thought to be 8.7 million species on planet Earth. And, as we saw in the video, "Why does biodiversity matter to me?", biodiversity is of utmost importance to humans.
The loss of one key species can have a detrimental impact on many levels; from other species of animals to plants to the physical environment.
Human activities are reducing biodiversity. Our future depends upon maintaining a good level of biodiversity, and so we need to start taking measures to try and stop the reduction.
In this video, we are going to look at how humans are negatively impacting biodiversity.
As the world population has grown from 1.5 billion in 1900 to nearly 7.5 billion people ...

Global Change Biology: A Primer

Read the article: https://doi.org/10.1111/gcb.14893
Because of human action, the Earth has entered an era where profound changes in the global environment are creating novel conditions that will be discernable far into the future. One consequence may be a large reduction of the Earth's biodiversity, potentially representing a sixth mass extinction. With effective stewardship, the global change drivers that threaten the Earth's biota could be alleviated, but this requires clear understanding of the drivers, their interactions, and how they impact ecological communities. This review identifies 10 anthropogenic global change drivers and discusses how six of the drivers (atmospheric CO2 enrichment, climate change, land transformation, species exploitation, exotic species invasions, eutrophication) impact Earth's biodiversity. Driver impacts on a particular species could be positive or negative. In either case, they initiate secondary responses that cascade along ecological lines of connection and in doing so magnify the initial impact. The unique nature of the threat to the Earth's biodiversity is not simply due to the magnitude of each driver, but due to the speed of change, the novelty of the drivers, and their interactions. Emphasizing one driver, notably climate change, is problematic because the other global change drivers also degrade biodiversity and together threaten the stability of the biosphere. As the main academic journal addressing global change effects on living systems, GCB is well positioned to provide leadership in solving the global change challenge. If humanity cannot meet the challenge, then GCB is positioned to serve as a leading chronicle of the sixth mass extinction to occur on planet Earth.

Research challenges and opportunities for using big data in global change biology
Jianyang Xia, Jing Wang, Shuli Niu
Read the article: https://doi.org/10.1111/gcb.15317
Global change biology has been entering a big data era due to the vast increase in availability of both environmental and biological data. Big data refers to large data volume, complex data sets, and multiple data sources. The recent use of such big data is improving our understanding of interactions between biological systems and global environmental changes. In this review, we first explore how big data has been analyzed to identify the general patterns of biological responses to global changes at scales from gene to ecosystem. After that, we investigate how observational networks and space‐based big data have facilitated the discovery of emergent mechanisms and phenomena on the regional and global scales. Then, we evaluate the predictions of terrestrial biosphere under global changes by big modeling data. Finally, we introduce some methods to extract knowledge from big data, such as meta‐analysis, machine learning, traceability analysis, and data assimilation. The big data has opened new research opportunities, especially for developing new data‐driven theories for improving biological predictions in Earth system models, tracing global change impacts across different organismic levels, and constructing cyberinfrastructure tools to accelerate the pace of model‐data integrations. These efforts will uncork the bottleneck of using big data to understand biological responses and adaptations to future global changes.

The term climate change is used to denote the long-term changes in the weather patterns in a given region. Another term often interchanged with climate change is global warming. Global warming is formally defined as a rise in Earth's temperature that persists for a decade or longer.
There could be several causes for climate change, but the biggest one is the rising concentration of greenhouse gases. Simply put, greenhouse gases are those gases in our atmosphere that trap heat. Some examples include carbon dioxide, methane, chlorofluorocarbons, nitrous oxide and ozone.
Natural sources and human activities both result in the emission of greenhouse gases. One of the most common ways these gases get released into the atmosphere is through the burning of fossil fuels. Burning coal or oil to run industrial processes or giant factories increases the concentration of atmospheric carbon dioxide. Indeed, fossil fuels' contribution to greenhouse gas emissions is the largest, in the range of 70- 80% of total emissions.
In this video, we explain, in simple terms, climate change and global warming and what we can do as a community and individually to save Earth from climate change.

Advancing Global Change Biology Through Experimental Manipulations: Where Have We Been and Where Might We Go?
Hanson, Paul; Walker, Anthony
Read the article: https://doi.org/10.1111/gcb.14894
This commentary summarizes the publication history of Global Change Biology for works on experimental manipulations over the past 25 years and highlights a number of key publications. The retrospective summary is then followed by some thoughts on the future of experimental work as it relates to mechanistic understanding and methodological needs. Experiments for elevated CO2 atmospheres and anticipated warming scenarios which take us beyond historical analogs are suggested as future priorities. Disturbance is also highlighted as a key agent of global change. Because experiments are demanding of both personnel effort and limited fiscal resources, the allocation of experimental investments across Earth's biomes should be done in ecosystems of key importance. Uncertainty analysis and broad community consultation should be used to identify research questions and target biomes that will yield substantial gains in predictive confidence and societal relevance. A full range of methodological approaches covering small to large spatial scales will continue to be justified as a source of mechanistic understanding. Nevertheless, experiments operating at larger spatial scales encompassing organismal, edaphic, and environmental diversity of target ecosystems are favored, as they allow for the assessment of long‐term biogeochemical feedbacks enabling a full range of questions to be addressed. Such studies must also include adequate investment in measurements of key interacting variables (e.g., water and nutrient availability and budgets) to enable mechanistic understanding of responses and to interpret context dependency. Integration of ecosystem‐scale manipulations with focused process‐based manipulations, networks, and large‐scale observations will aid more complete understanding of ecosystem responses, context dependence, and the extrapolation of results. From the outset, these studies must be informed by and integrated with ecosystem models that provide quantitative predictions from their embedded mechanistic hypotheses. A true two‐way interaction between experiments and models will simultaneously increase the rate and robustness of Global Change research.

Human Impacts on Biodiversity | Ecology and Environment | Biology | FuseSchool
Biodiversity is the variety of life. There are thought to be 8.7 million species on planet Earth. And, as we saw in the video, "Why does biodiversity matter to me?", biodiversity is of utmost importance to humans.
The loss of one key species can have a detrimental impact on many levels; from other species of animals to plants to the physical environment.
Human activities are reducing biodiversity. Our future depends upon maintaining a good level of biodiversity, and so we need to start taking measures to try and stop the reduction.
In this video, we are going to look at how humans are negatively impacting biodiversity.
As the world population has grown from 1.5 billion in 1900 to nearly 7.5 billion people today, unsurprisingly the land use has changed.
Habitats have been destroyed in favour of agriculture, forestry, fishing, urbanisation and manufacturing. Unsurprisingly, habitat loss has greatly reduced the species richness. Habitat fragmentation has also meant that populations have been split into smaller subunits, which then, when faced with challenging circumstances, have not been able to adapt and survive.
After habitat loss, over-harvesting has had a huge effect on biodiversity. Humans historically exploit plant and animal species for short-term profit. If a resource is profitable, we develop more efficient methods of harvesting it, inevitably depleting the resources, as is currently happening with fishing and logging. The exploited species then needs protection. The difficulty is that the demand then outstrips the supply, and so the resource value rises. This increases the incentive to extract the resource and leads to the final collapse of the population, as happened with whales, elephants, spotted cats, cod, tuna and many more species.
Human activities are polluting the air and water. Toxic discharge into the water from industrial processes unsurprisingly has a negative effect on the local aquatic species by killing, weakening or affecting their ability to reproduce. Another big water pollution problem is eutrophication. Phosphorous and nitrogen in fertilisers run-off agricultural fields and pass into rivers. These surplus nutrients cause algae to bloom, which then starves other aquatic species of oxygen and light, causing them to die.
Acid rain is one consequence of humans polluting the air. This causes lakes and water bodies to become more acidic, killing off fish, molluscs, amphibians and many other species.
A huge impact humans have had on planet Earth is the introduction of alien species to habitats. In fact, it is estimated that on any given day there are 3000 species in transit aboard ocean-going vessels! Alien species can cause problems in a number of ways.
Throughout the earth’s history there have been periods of rapid climate change that have led to mass extinction events. We are currently in a period of fluctuating climate, but nearly all scientists agree that human activities, like burning fossil fuels, are speeding up global warming.
We don’t know how much climate change is going to affect biodiversity in future, but it’s predicted to be huge. Loss of sea ice and ocean acidification are already causing huge reductions in biodiversity. Climate change alters temperature and weather patterns, with changing patterns of rainfall and drought expected to have significant impacts on biodiversity.
