Greenhouse Gas Emissions Hit Highest Levels<\/strong><\/h2>\n

50 Leading Scientists on \u201cUnprecedented\u201d Human-Caused Global Warming<\/strong><\/h3>\n

\u201cWe need to change policy and approaches in the light of the latest evidence about the state of the climate system. Time is no longer on our side.\u201d<\/h4>\n

BY DAVID LEWIS<\/strong><\/h3>\n

Human-caused global warming has continued to increase at an \u201cunprecedented rate\u201d since the last major assessment of the climate system published two years ago, say 50 leading scientists.<\/p>\n

One of the researchers said the analysis was a \u201ctimely wake-up call\u201d that the pace and scale of climate action have been insufficient.<\/p>\n

\u201cThis is the critical decade for climate change,\u201d says Piers Forster, director of the Priestley Centre for Climate Futures at Leeds. \u201cDecisions made now will have an impact on how much temperatures will rise and the degree and severity of impacts we will see as a result.\u201d<\/span><\/p>\n

Forster says that although the rate of increase in greenhouse gas emissions has slowed, \u201cwarming rates are currently at a long-term high.\u201d<\/span><\/p>\n

Human-induced warming is now increasing at a pace of 0.36\u00b0F per decade. The analysis also found that greenhouse gas emissions were \u201cat an all-time high,\u201d with human activity resulting in roughly 54 billion metric tons of carbon dioxide released into the atmosphere on average every year.<\/span><\/p>\n

Given the speed at which the global climate system is changing, the scientists argue that policymakers, climate negotiators, and civil society groups need to have access to up-to-date and robust scientific evidence on which to base decisions. The authoritative source of scientific information <\/span>on the state of the climate is the UN\u2019s Intergovernmental Panel on Climate Change (IPCC), but the turnaround time for its major assessments is five or ten years.<\/span><\/p>\n

That creates an \u201cinformation gap,\u201d particularly when climate indicators are changing rapidly.<\/p>\n

In a new initiative through the University of Leeds, the scientists have developed an open science climate tracker \u2014 \u201cIndicators of Global Climate Change\u201d \u2014 that will update information on key climate indicators every year. <\/span><\/p>\n

As recent IPCC reports have conclusively shown, with every further increment of global warming, the frequency and intensity of climate extremes \u2014 including hot extremes, heavy rainfall, and agricultural droughts \u2014 increases.<\/span><\/p>\n

\u201cWe need to be nimble footed in the face of climate change,\u201d Forster says. \u201cWe need to change policy and approaches in the light of the latest evidence about the state of the climate system.\u201d<\/span><\/p>\n

Forster adds that access to up-to-date information is vital. \u201cTime is no longer on our side.\u201d<\/span><\/p>\n
