This common lionfish (
Pterois volitans) was sighted more than 200km further south than expected down the NSW coast by 14-year-old scuba diver Georgia Poyner. It’s one of almost 40 verified observations she has submitted to Redmap.
We know the warming seas are forcing some marine life to new waters, but we don't know much about how fast and how far they are moving. But now you can help scientists find the answers with Redmap.
Low carbon choices such as solar power are essential for the African continent, if it intends to stop the harmful global warming effects.
For the sake of mitigating climate change, the African continent needs to make low carbon energy choices.
Places near the equator, with less natural climate variation, were the first to see humanity’s climate fingerprint.
Global warming is, by definition, experienced worldwide. But a new study shows that the tropics were the first places on earth where the human effect on climate outstripped normal climate variations.

The latest science on hurricanes and climate change explained – vital information for coastal regions to prepare for the effects of more intense storms.
Really dry: a Colorado River aqueduct in southern California.
Historical analysis shows that natural forces are behind California’s drought, but global warming has contributed 8%-27% to the drought’s severity.
Look to the Pacific for reasons behind the hiatus.
Study of natural variability explains slowdowns in the rate of warming in recent decades – and is key to improving climate models.
Sea level rise is one of the biggest worries of climate change. This image is from the Witness King Tides project, which aims to visualise sea level rise using large tides and storm surges.

Sea level rise represents one of the most worrying aspects of global warming, potentially displacing millions of people along coasts, low river valleys, deltas and islands.

A dedicated group of forward-looking experts have crunched the numbers on human progress. There's good news, and there's bad news.
Piton de la Fournaise or “Peak of the Furnace” on Reunion Island is one of the world’s most active volcanoes, shown erupting in August 2015.
What happens beneath the surface before a volcano erupts? Can we predict when one will blow? And how can typhoons and melting glaciers contribute to big eruptions?
Study raises new questions over the rate of ice melting, and thus sea level rise.
NASA's former climate chief, James Hansen, is lead author on a paper that predicts rapidly rising seas this century, but not all climate scientists believe the study's models are convincing.
Once there was water….
Some atomic ratio detective work on our solar system neighbors tells us a lot about their watery pasts. That Venus and Mars are mostly dry now could be a cautionary tale for us on the Blue Planet.
New data set includes more accurate data from the Arctic, where more warming has occurred.
NOAA review reveals that difficult-to-explain slowdown in higher temperatures from global warming was based on faulty data.
A new analysis of historic weather balloon data reveals that the troposphere has been warming as climate models predicted.
Climate models have been criticised because observations could not find the predicted "hot spot" of strong warming in the troposphere. But analyses now show that the tropospheric hot spot is indeed real.
We cross the 2C threshold at our peril.
2C is the officially agreed safe limit for global warming, but a recent expert finds 2C is still in the danger zone.
With sea levels rising, a managed retreat from the coastline is necessary.
In areas vulnerable to sea level rise and storm surges, developments are at increasing risk of inundation and permanent damage over coming years.
Out of sight out of mind? The vast majority of global warming is going into the ocean.
Over the past decade, warming air temperatures at Earth's surface appear to have slowed. But that ignores the vast majority of heat going steadily into the ocean. And, a new paper shows, that makes no difference to the long-term prognosis.
It’s hard to know for sure what role climate change played in the intensity of Cyclone Pam.

A causal relationship between cyclone behaviour and anthropogenic global warming is a very real possibility. But most climate scientists hesitate to attribute any single event to global warming.
Despite adjustments to temperature data in the Arctic, the overall global warming trend remains the same.

A few more trees and a little less aircon and we’d all be in clover.

Cities may only occupy about 2% of the world’s habitable land, but they are big drivers of global climate change. Cities are usually hotter than rural areas, and get referred to in the jargon as “urban…
Imagine the smokestacks without the billowing clouds of greenhouse gas pollution.
Earth’s climate is changing rapidly. We know this from billions of observations, documented in thousands of journal papers and texts and summarized every few years by the United Nations' Intergovernmental…
