There are parallels between today’s and past greenhouse gas-driven climate changes

August 1, 2017 — Coincidence doesn’t prove causality, as they say, but when the same two things happen together over and over again through the vast span of geological time, there must be a causal link. Continue reading Underground magma triggered Earth’s worst mass extinction with greenhouse gases

Record heat, drought and continued glacier retreat show global warming fingerprint in 2015 state of the climate report

August 2, 2016 — Every year, meteorologists pull together a state of the climate report.

Thomas Karl, director at NOAA, the US agency that coordinates data and analysis from all over the world, describes it as an “annual physical” of the Earth’s climate system.  Continue reading Five markers of climate change in 2015’s weather

Experts warn sea level rise will accelerate in the coming decades, putting millions of lives at risk worldwide

MIAMI, USA (Aug. 3, 2016) — Global heat, greenhouse gases, and sea levels all climbed to record highs last year, making 2015 the worst in modern times across a range of key environmental indicators, international scientists said Tuesday, August 2.  Continue reading Global heat, sea level hit record highs in 2015

July 27, 2016 — A global agreement on cutting the use of hydrofluorocarbons (HFCs) – potent greenhouse gases used in aerosols, refrigerants and air conditioning – seems within grasp, delegates said on Sunday after ten days of talks on climate change in Vienna.  Continue reading Deal on cutting greenhouse gases in sight for this year

Antarctic peninsula temperatures have fallen, study shows

Scientists said cooling of tip over past 15 years is related to wind patterns, but does not mean that global warming has stopped

July 21, 20116 — The tip of the Antarctic peninsula has cooled over the past 15 years, scientists have found, but the discovery does not mean global warming has stopped.  Continue reading Antarctic peninsula temperatures have fallen, study shows

More than 800,000 volunteers pitched in to help the country fight climate change.

July 20, 2016 — Although the feat has yet to be certified by Guinness World Records, Indian officials have reported that volunteers planted a whopping 49.3 million tree saplings on July 11, blowing past the previous record for most trees planted in a single day.  Continue reading India Plants 50 Million Trees in One Day, Smashing World Record

Tropical storms to get fiercer as the world warms

Turbocharged weather events like Typhoon Nepartak, Hurricane Katrina and Superstorm Sandy are expected to become more common with climate change

July 18, 2016 — Powerful tropical storms − known variously as cyclones, typhoons and hurricanes − bring death and destruction to huge swathes of the Earth’s surface. And new research suggests that they are likely to become even stronger.  Continue reading Tropical storms to get fiercer as the world warms

Global warming is shifting Earth’s clouds, study shows

The warming of the planet over the past few decades has shifted a key band of clouds poleward and increased the heights of clouds tops

July 14, 2016 — The reaction of clouds to a warming atmosphere has been one of the major sources of uncertainty in estimating exactly how much the world will heat up from the accumulation of Continue reading Global warming is shifting Earth’s clouds, study shows

Pacific Ocean behind recent Antarctic sea ice growth

Scientists have long been searching for an explanation for the contrasting fortunes of sea ice at the Earth’s poles. While the Arctic has seen a rapid decline in sea ice extent in recent decades, the seas around Antarctica have slowly gained ice.

July 7, 2016 — Now, a new study suggests a natural shift from one state to another in the Pacific Ocean is responsible for the increase in Antarctic sea ice.  Continue reading Pacific Ocean behind recent Antarctic sea ice growth

Burning all fossil fuels would scorch Earth

Researchers predict that average temperatures would climb by up to 9.5°C if all known reserves of oil, gas, and coal are burned

BONN, Germany (May 24, 2016) — Using up all known fossil fuel reserves would render Earth even more unliveable than scientists had previously projected, researchers said on Monday, May 23. Continue reading Burning all fossil fuels would scorch Earth
