Fingers In Ears

With her digits firmly planted in her ears Joanne Nova pretends that AGW is not happening. The science says otherwise. Perhaps Jo is too busy with Tony “It’s crap” Abbott’s political campaign to write about the science, or perhaps it’s just because these climate science papers don’t agree with her preconceived, politically motivated, scientifically-unsupported, blogger opinion? Here’s a small sample of recent peer-reviewed science Joanne wants to wish away.

update: Nova has commented on this list saying “I can rebut most just from their headlines.” … but of course she doesn’t go any further than that and instead yet another person gets “moderated” when the topic becomes too much for Nova. Joanne repetitively points to her “Evidence”, a page which we’ve covered in detail .

Spread of Crop Pests Threatens Global Food Security as Earth Warms

A new study has revealed that global warming is resulting in the spread of crop pests towards the North and South Poles at a rate of nearly 3 kilometers a year.

On Warming Antarctic Peninsula, Moss and Microbes Reveal Unprecedented Ecological Change

By carefully analyzing a 150-year-old moss bank on the Antarctic Peninsula, researchers reporting in Current Biology, a Cell Press publication, on August 29 describe an unprecedented rate of ecological change since the 1960s driven by warming temperatures.

Where Can Coral Reefs Relocate to Escape the Heat?

Global warming is stronger at the equator and drives corals away into higher latitudes, whereas acidification is stronger close to the poles and pushes coral habitat towards the equator.

Wildfires Projected to Worsen With Climate Change

The Harvard team’s study suggests wildfire seasons by 2050 will be about three weeks longer, up to twice as smoky, and will burn a wider area in the western states.

East Antarctic Ice Sheet Could Be More Vulnerable to Climate Change Than Previously Thought

Using measurements from 175 glaciers, the researchers were able to show that the glaciers underwent rapid and synchronised periods of advance and retreat which coincided with cooling and warming. The researchers said this suggested that large parts of the ice sheet, which reaches thicknesses of more than 4km, could be more susceptible to changes in air temperatures and sea-ice than was originally believed.

Insight Into Marine Life’s Ability to Adapt to Climate Change

Researchers have discovered that some species of polychaete worms are able to modify their metabolic rates to better cope with and thrive in waters high in carbon dioxide (CO2), which is otherwise poisonous to other, often closely-related species. … ”In this sense, our findings could help to explain mass extinctions of the past, and potential extinctions in the future, as well as shed light on the resilience of some species to on-going ocean acidification.”

Ocean Acidification Amplifies Global Warming

The ocean, by taking up significant amounts of CO2, lessens the effect of this anthropogenic disturbance. The “price” for storing CO2 is an ongoing decrease of seawater pH (ocean acidification), a process that is likely to have diverse and harmful impacts on marine biota, food webs, and ecosystems. … As marine DMS emissions are the largest natural source for atmospheric sulfur, changes in their strength have the potential to notably alter Earth’s radiation budget.

Scientists Analyze the Effects of Ocean Acidification On Marine Species

The results of this new assessment are clear. “Our study showed that all animal groups we considered are affected negatively by higher carbon dioxide concentrations. Corals, echinoderms and molluscs above all react very sensitively to a decline in the pH value,” says Dr. Astrid Wittmann.

Potential for Successful Climate Predictions: Hindcast Experiments Capture Long-Term Climate Fluctuations

What happened in the years 1976/77 and 1998/99 in the Pacific was so unusual that scientists spoke of abrupt climate changes. They referred to a sudden warming of the tropical Pacific in the mid-1970s and rapid cooling in the late 1990s. Both events turned the world’s climate topsy-turvy and are clearly reflected in the average temperature of Earth. Today we know that the cause is the interaction between ocean and atmosphere. Is it possible to successfully predict such climate shifts? This is the question that scientists, under the auspices of the GEOMAR Helmholtz Centre for Ocean Research Kiel, pursued. Using a coupled model of the ocean and the atmosphere, they were able to successfully replicate these events.

Food Source for Whales, Seals and Penguins at Risk: Warming Antarctic Seas Likely to Impact On Krill Habitats

Lead author, Dr. Simeon Hill, a marine biologist at BAS, said: “Each year, growth of Antarctic krill in the Southern Ocean produces new material that weighs twice as much as all the sugar produced in the world. Krill grow fastest in cold water and any warming can slow down or stop growth, reducing the food available for wildlife. Our research suggests that expected warming this century could severely reduce the area in which krill can successfully grow.”

Future Flood Losses in Major Coastal Cities: Costly Projections

Climate change combined with rapid population increases, economic growth and land subsidence could lead to a more than nine-fold increase in the global risk of floods in large port cities between now and 2050.

Ringing the Changes: What Museum Specimens Reveal About Climate Change

Records from the UK Butterfly Monitoring Scheme show that since 1976, spring has arrived 6-11 days earlier each decade due to rising temperatures. Now, ecologists from the Natural History Museum (NHM) and the University of Coventry have used some of the museum’s 130,000 butterfly specimens collected over the past 200 years to look back at earlier springs.

Heat Waves to Become Much More Frequent and Severe

Extreme heat waves such as those that hit the US in 2012 and Australia in 2009 — dubbed three-sigma events by the researchers — are projected to cover double the amount of global land by 2020 and quadruple by 2040.

Warming Climate Pushes Plants Up the Mountain

Comparing plant communities today with a survey taken 50 years ago, a UA-led research team is providing the first on-the-ground evidence for Southwestern plants being pushed to higher elevations by an increasingly warmer and drier climate.

Extreme Weather Events Fuel Climate Change

The investigations of the current study, however, show that the consequences of weather extremes can be far-reaching. “As extreme climate events reduce the amount of carbon that the terrestrial ecosystems absorb and the carbon dioxide in the atmosphere therefore continues to increase, more extreme weather could result,” explains Markus Reichstein. “It would be a self-reinforcing effect.”

Why an Ice Age Occurs Every 100,000 Years: Climate and Feedback Effects Explained

Nowadays, Milankovitch’s theory is widely accepted. “Milankovitch’s idea that insolation determines the ice ages was right in principle,” says Blatter. “However, science soon recognised that additional feedback effects in the climate system were necessary to explain ice ages. We are now able to name and identify these effects accurately.”

Study Questions Nature’s Ability to ‘Self-Correct’ Climate Change

By performing tests on subtropical woodland plots over an 11-year period, the researchers found that ecosystem carbon uptake was not significantly increased by the high CO2 treatment-in contrast to expectations. While plants did contain more carbon when CO2 levels were increased, soil actually lost carbon due to microbial decomposition; both factors essentially balanced one another out.

Carbon Emissions to Impact Climate Beyond the Day After Tomorrow

A standard value for present-day climate sensitivity is about 3°C per doubling of atmospheric CO2. But according to Zeebe, climate sensitivity could change over time. Zeebe uses past climate episodes as analogs for the future, which suggest that so-called slow climate ‘feedbacks’ can boost climate sensitivity and amplify warming.

Disappearance of Coral Reefs, Drastically Altered Marine Food Web On the Horizon

But, if fossil fuel use stays on its current trajectory until the end of this century, then the climate effects begin to resemble those of the PETM, with major ecological changes lasting for 20,000 years or more and a recognizable human “fingerprint” on Earth’s climate lasting for 100,000 years.

Looking to the Past to Predict the Future of Climate Change

Climate change has occurred repeatedly throughout Earth’s history, but the recent rate of global warming far exceeds that of any previous episode in the past 10,000 years or longer. … “Looking to the past is one of the few ways ecologist have for understanding how natural systems respond to climate change,” said Fitzpatrick of the Center’s Appalachian Laboratory. “When we look to the fossil record, from hundreds of millions of years ago to near present day, we see episodes of climatic change and biological upheaval, and we see similar patterns.”

Global Investigation Reveals True Scale of Ocean Warming: Species Changing Breeding Times, Shifting Homes

Professor Parmesan said: “This is the first comprehensive documentation of what is happening in our marine systems in relation to climate change. What it reveals is that the changes that are occurring on land are being matched by the oceans. And far from being a buffer and displaying more minor changes, what we’re seeing is a far stronger response from the oceans.”

Climate Change Occurring Ten Times Faster Than at Any Time in Past 65 Million Years

The planet is undergoing one of the largest changes in climate since the dinosaurs went extinct. But what might be even more troubling for humans, plants and animals is the speed of the change. Stanford climate scientists warn that the likely rate of change over the next century will be at least 10 times quicker than any climate shift in the past 65 million years.

    Joanne suffers from the Dunning–Kruger effect. She thinks she has all the answers, but in reality she delivers nothing. She refers to the same old link no matter what people are arguing about. She has no answer for what is causing the warming, if it was not CO2, has no answer for what causes the massive amount of heat to gather in the ocean and cannot refer to peer-reviewed litereature in order to support her claims. Her recent posts are obviously politically motivated and she also has investments in the mining industry.

  2. Michael Caldwell Says:

    The sun causes the warming 354 W/sqm. The amount of heat hat reaches the surface varies with atmospheric absorption and the albedo effect mainly caused by cloud refection not modelled in GCM’s. The heat is distributed in the main by the world’s oceans. The oceans have never been and will never be acidic and will remain alkaline. Rises in atmospheric CO2 (398 ppmv) follow ocean warming. Check the solubility curves for CO2 in sea water. It’s all very simple. Why don’t you stop peer review and get back to the scientific method of observation, theory proposition, theory testing and if the theory fails, revise the theory. The theory of global warming latterly changed to climate change is caused by man-made CO2 is busted and the GCM don’t work
