Click for more detail Thermohaline Change Evidence is growing that the thermohaline current may be slowed or stopped by cold fresh water inputs to the Arctic and North Atlantic oceans. This could occur if global warming is sufficient to cause large scale melting of arctic sea ice and the Greenland ice sheet. Such a change in the current may be gradual (over centuries) or very rapid (over a few years). "Diatoms (a kind of phytoplankton) are estimated to "scrub" roughly as much CO2 from the atmosphere each year as all the world's rainforests. "Net primary productivity is the mass of plant material produced each year on land and in the oceans by photosynthesis using energy from sunlight. Biodiversity is the variety of life found at all levels of biological organization, ranging from individuals and populations to species, communities and ecosystems.

Global risks: Interactive map shows climate issues rising An overly simplistic view of global economics has fuelled climate denial and skepticism for decades. Some opponents of climate change mitigation policies argue that achieving any progress would require an impossible retrofitting of our economy and result in lower profits and fewer jobs. In reality, in many ways, climate action will help businesses be more resilient in tomorrow’s economy. Interestingly, the rapid and widespread outbreak of COVID-19 has given the world an opportunity to test the hypothesis of whether and how an economic shutdown might affect climate outcomes. Initial data suggests that 2020 annual emissions could decrease by as much as seven percent globally due to the downward shift in energy demand worldwide. Climate change poses an urgent threat demanding decisive action. The World Economic Forum's Climate Initiative supports the scaling and acceleration of global climate action through public and private-sector collaboration. Contact us to get involved.

The scientific consensus on global warming « Later On From the American Association for the Advancement of Science (AAAS), the preeminent scientific organization in the US. Note that this article is not based on a mere count of articles, but rather looks at statements from various scientific organizations. Science 3 December 2004: Vol. 306. no. 5702, p. 1686 DOI: 10.1126/science.1103618BEYOND THE IVORY TOWER: The Scientific Consensus on Climate ChangeNaomi Oreskes*Policy-makers and the media, particularly in the United States, frequently assert that climate science is highly uncertain. Some have used this as an argument against adopting strong measures to reduce greenhouse gas emissions. For example, while discussing a major U.S. Environmental Protection Agency report on the risks of climate change, then-EPA administrator Christine Whitman argued, “As [the report] went through review, there was less consensus on the science and conclusions on climate change” (1).

5 reasons why biodiversity matters to health and the economy Biodiversity is critically important to human health, economies and livelihoods. Humans have caused the loss of 83% of all wild animals and half of all plants. To mark the International Day for Biodiversity, here are five reasons why biodiversity matters to humans – and why we need to protect it. Biodiversity is critically important – to your health, to your safety and, probably, to your business or livelihood. But biodiversity – the diversity within species, between species and of ecosystems – is declining globally, faster than at any other time in human history. In celebration of the International Day for Biological Diversity, we break down the five ways in which biodiversity supports our economies and enhances our wellbeing – and has the potential to do even more. 1. Biodiversity underpins global nutrition and food security. People once understood that the conservation of species was crucial for healthy societies and ecosystems. 2. First, plants are essential for medicines. 3. 4. 5.

Arctic Warming is Altering Weather Patterns, Study Shows EDITOR'S NOTE: This story was originally published April 3. Given recent news that Arctic sea ice set a record low, it's a reminder that changes in the Arctic can affect the U.S. and Europe. By showing that Arctic climate change is no longer just a problem for the polar bear, a new study may finally dispel the view that what happens in the Arctic, stays in the Arctic. The study, by Jennifer Francis of Rutgers University and Stephen Vavrus of the University of Wisconsin-Madison, ties rapid Arctic climate change to high-impact, extreme weather events in the U.S. and Europe. The study shows that by changing the temperature balance between the Arctic and mid-latitudes, rapid Arctic warming is altering the course of the jet stream, which steers weather systems from west to east around the hemisphere. The jet stream, the study says, is becoming “wavier,” with steeper troughs and higher ridges. The strong area of high pressure shunted the jet stream far north into Canada.

The Global Risks Report 2020 The 15th edition of the World Economic Forum’s Global Risks Report is published as critical risks are manifesting. The global economy is facing an increased risk of stagnation, climate change is striking harder and more rapidly than expected, and fragmented cyberspace threatens the full potential of next-generation technologies — all while citizens worldwide protest political and economic conditions and voice concerns about systems that exacerbate inequality. The challenges before us demand immediate collective action, but fractures within the global community appear to only be widening. Stakeholders need to act quickly and with purpose within an unsettled global landscape. Read the Japanese version here日本語はこちら

Global Warming Facts, Causes and Effects of Climate Change Jump to Section Q: What is global warming? A: Since the Industrial Revolution, the global annual temperature has increased in total by a little more than 1 degree Celsius, or about 2 degrees Fahrenheit. Between 1880—the year that accurate recordkeeping began—and 1980, it rose on average by 0.07 degrees Celsius (0.13 degrees Fahrenheit) every 10 years. Since 1981, however, the rate of increase has more than doubled: For the last 40 years, we’ve seen the global annual temperature rise by 0.18 degrees Celsius, or 0.32 degrees Fahrenheit, per decade. The result? Now climate scientists have concluded that we must limit global warming to 1.5 degrees Celsius by 2040 if we are to avoid a future in which everyday life around the world is marked by its worst, most devastating effects: the extreme droughts, wildfires, floods, tropical storms, and other disasters that we refer to collectively as climate change. Q: What causes global warming? Q: How is global warming linked to extreme weather? A: No!

Green Brexit: a new era for farming, fishing and the environment I want to thank Prosperity UK for organising this conference and in particular, Lord Hill of Oareford, Sir Paul Marshall and Alex Hickman who have been the dynamos who have ensured that today can occur. And they, like the team that run Prosperity UK, are determined to bring together individuals from across the political spectrum to develop policies for Britain’s future outside the European Union (EU). Their committee is composed of both those who argued that we should Leave the EU and also those who believed that we should Remain But they are united by the belief that, whatever positions individuals may have been adopted in the past it’s important that all of us now focus on the opportunities of the future. I want to set out, in a second, where I believe some of those opportunities specifically lie. But more than sixteen million of our fellow citizens voted to Remain. Many people voted to Remain because they understandably feared the economic consequences of leaving. CAP reform Fisheries

25 Year Environment Plan Our environment plan sets out our goals for improving the environment, within a generation, and leaving it in a better state than we found it. It details how we in government will work with communities and businesses to do this. It sets out what we will be doing over the next 25 years. Alongside the plan, we’ve published 3 detailed, technical annexes. We published the first annual progress report in May 2019. The Plan sits alongside two other important government strategies: our Industrial Strategy and our Clean Growth strategy.

Horticultural Research by Stockbridge Technology Centre Precision approaches for sustainable soils - CHAP Challenge: Agricultural production needs to increase by 60% by 2050 in order to feed the growing global population. Despite this, improvements to crop yields have shown signs of having plateaued, while pressure on farmers to produce crops sustainably with fewer inputs has grown. The arable sector also faces the need to meet other key production challenges, as driven by political, societal and environmental pressures. These include reduction of soil erosion and surface water pollution, fixing of atmospheric nitrogen and recycling of unused soil nitrogen, and, critically, the management and improvement of soil health, which underpins productivity as well as environmental benefits. Precision approaches and technologies will play a key role in successful, economically viable and resilient management of crop systems to maximise soil health gains, while supporting yield resilience. Methodology: Living mulches, soil health, and grand challenges:

A move towards precision farming will lead to an improved farm ecosystem - CHAP The green revolution was ushered in by new chemistry, mechanisation and advances in plant breeding. The results were miraculous gains in crop yields around the globe, but at what cost? The increased reliance on petroleum-based inputs transformed the image of agriculture into one of the dirtiest industries in the world. At the same time, increased yields from plant breeding seems to have been achieved at the cost of lower levels of key nutrients in the food produced. Precision revolution Now we are at the forefront of a new revolution guided by precision technologies with the potential to change agriculture into something more sustainable and beneficial to consumers. These technologies have obvious positives such as using less heavy and fuel hungry vehicles and less inputs applied which all saves money and time (which famously is money). Wider Benefits Less obvious, but arguably more valuable outcomes, include the potential restoration of soil and wider ecosystem health. Collaboration is key
