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.

Sea Level Rise Explorer - Global Warming Art From Global Warming Art Elevation Relative to Sea Level (m) Description The map shown above allows you to explore the regions of the Earth that are most vulnerable to sea level rise. As with other Google Maps, you can click-and-drag the window to scroll or double click to zoom. Potential for Sea Level Rise As global warming progresses, sea level is expected to rise primarily due to the melting of continental ice sheets in Greenland and Antarctica. During the twentieth century, sea level rose 20 cm. However, even if global temperatures stabilize in 2100, the full magnitude of sea level rise is expected to take far longer to develop. Accuracy of Maps The sea level data appearing in my maps is based primarily on version 2 of NASA's Shuttle Radar Topography Mission (SRTM), with post-processing by CGIAR to fill-in voids using data from other sources. The SRTM data are limited to a region of 60 S to 60 N latitude. Related Materials References ^ [abstract] [DOI] Knutti, Reto and Thomas F.

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.

Why Critique 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).

Apps That Challenge Kids to Solve Environmental Issues By Tanner Higgin, Graphite Environmental education for most adults used to mean learning a little bit about recycling and planting some trees on Arbor Day. We didn’t delve into ecology as much as we skimmed the surface. But things have gotten more complex since then, and the topic of climate change has brought environmental education to the forefront. At its best, environmental education gets students grappling with big, cross-disciplinary issues like sustainable design and renewable energy. Students think critically about environmental and ecological systems; they diagnose problems, and speculate about (or maybe even create) solutions. 1. This app provides an overview of environmental issues, particularly pollution, for younger students. 2. Enercities is a little more sophisticated than Little Green Island. 3. It’s important to learn not just about sustainability and being environmentally conscious, but also about what’s at stake in these efforts. 4. Related

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

Reference, Facts, News - Free and Family-friendly Resources - Refdesk.com 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.

Global Warming and Climate Change skepticism examined 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

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!
